How to Calculate the Input and Output Speeds of a Worm Gearbox?

Calculating the input and output speeds of a worm gearbox involves understanding the gear ratio and the principles of gear reduction. Here’s how you can calculate these speeds:

  • Input Speed: The input speed (N1) is the speed of the driving gear, which is the worm gear in this case. It is usually provided by the manufacturer or can be measured directly.
  • Output Speed: The output speed (N2) is the speed of the driven gear, which is the worm wheel. To calculate the output speed, use the formula:

    N2 = N1 / (Z1 * i)

Where:
N2 = Output speed (rpm)
N1 = Input speed (rpm)
Z1 = Number of teeth on the worm gear
i = Gear ratio (ratio of the number of teeth on the worm gear to the number of threads on the worm)

It’s important to note that worm gearboxes are designed for gear reduction, which means that the output speed is lower than the input speed. Additionally, the efficiency of the gearbox, friction, and other factors can affect the actual output speed. Calculating the input and output speeds is crucial for understanding the performance and capabilities of the worm gearbox in a specific application.

Applications
X helical gear units for double-screw extruders with parallel drive shafts and the same direction of screw rotation are used mainly in the manufacture of granulates and the refining of raw plastics. Other areas of application include:

  • Paint and lacquer industry
  • Washing agent industry
  • Foodstuff industry (e.g. bread, pasta)
  • Animal-feed industry (dog, cat other animal food 

Maintenance of the gearbox of the dual-screw extruder
1. The gear box of the dual-screw extruder should be well-ventilated, and the working environment temperature should be within the range of 5-35 °C.
2. Always check the oil quantity of the gear lubricating oil in the box to ensure that the transmission parts in the box are well lubricated.
3. Pay attention to check the bearing parts of the box frequently. The oil temperature of the oil tank of the transmission box should not exceed 70 ºC during operation.
4. The newly put into use gearbox needs to replace the lubricating oil after 250 hours of operation. The oil change time depends on the state of the oil. It is recommended to replace it after 4000-8000 hours of operation or once a year.
5. The gearbox of the dual-screw extruder needs to be regularly maintained and inspected once a year 

Operating Process
1. The gear on the input shaft is driven by the motor and starts to rotate.
2. The rotating input gear meshes with other gears inside the gearbox, transmitting power.
3. Different-sized gears within the gearbox are combined to form a gear train. Through continuous meshing and rotation, the high-speed, low-torque power from the input shaft gradually converts into low-speed, high-torque output.
4. The output shaft is connected to the last gear and transfers the output torque to the load.
5. Gear reduction gearboxes typically include lubrication and cooling systems to ensure smooth operation and prevent overheating and damage.
6. Our extruder gearbox converts high-speed, low-torque power into low-speed, high-torque output by changing the size ratios and meshing arrangements of different gears, achieving the function of speed reduction.

Types of Gearboxes:
Based on customer requirements, gear reduction gearboxes can be classified according to the size of the output shaft, center distance of the output shaft, output speed, and torque. Alternatively, we can provide several commonly used types of gearboxes for customers to choose from.

Calculating Gear Ratio in a Worm Reducer

The gear ratio in a worm reducer is determined by the number of teeth on the worm wheel (also known as the worm gear) and the number of threads on the worm shaft. The gear ratio formula for a worm reducer is:

Gear Ratio = Number of Teeth on Worm Wheel / Number of Threads on Worm Shaft

For example, if the worm wheel has 60 teeth and the worm shaft has a single thread, the gear ratio would be 60:1.

It’s important to note that worm reducers have an inherent self-locking property due to the angle of the worm threads. As a result, the gear ratio also affects the mechanical advantage and the system’s ability to resist backdriving.

When calculating the gear ratio, ensure that the worm reducer is properly designed and that the gear ratio aligns with the desired mechanical characteristics for your application. Additionally, consider factors such as efficiency, load capacity, and speed limitations when selecting a gear ratio for a worm reducer.

Worm Gearboxes in Conveyor Systems: Benefits and Considerations

Worm gearboxes play a crucial role in conveyor systems, offering several benefits and considerations for their effective integration:

  • Space Efficiency: Worm gearboxes have a compact design, making them suitable for applications with limited space, such as conveyor systems.
  • High Reduction Ratios: Worm gearboxes can achieve high reduction ratios in a single stage, allowing for slower conveyor speeds without sacrificing torque.
  • Self-Locking: Worm gearboxes have inherent self-locking properties, preventing the conveyor from moving when the motor is not actively driving it.
  • Directional Control: Worm gearboxes facilitate directional control, enabling the conveyor to move forward or reverse as needed.
  • Low Noise: Worm gearboxes often produce lower noise levels compared to other gearbox types, contributing to quieter conveyor operation.

However, there are also considerations to keep in mind when using worm gearboxes in conveyor systems:

  • Efficiency: Worm gearboxes may have lower mechanical efficiency compared to some other gearbox types, leading to energy losses.
  • Heat Generation: Worm gearboxes can generate more heat due to sliding contact between the worm and gear, necessitating proper cooling mechanisms.
  • Lubrication: Proper lubrication is critical to prevent wear and ensure efficient operation. Regular maintenance is required to monitor lubrication levels.
  • Load and Speed: Worm gearboxes are well-suited for applications with high torque and low to moderate speed requirements. They may not be optimal for high-speed conveyors.

Before integrating a worm gearbox into a conveyor system, it’s important to carefully consider the specific requirements of the application, including load, speed, space constraints, and efficiency needs. Consulting with gearbox experts and manufacturers can help ensure the right choice for the conveyor’s performance and longevity.

Preventing Backlash in a Worm Gearbox

Backlash in a worm gearbox can lead to reduced accuracy, positioning errors, and decreased overall efficiency. Here are steps to prevent or minimize backlash:

  • High-Quality Components: Use high-quality worm gears and worm wheels with tight manufacturing tolerances. Precision components will help reduce backlash.
  • Proper Meshing: Ensure the worm gear and worm wheel are properly aligned and meshed. Improper meshing can lead to increased backlash.
  • Preload: Applying a small amount of preload to the worm gear can help reduce backlash. However, excessive preload can increase friction and wear.
  • Anti-Backlash Mechanisms: Consider using anti-backlash mechanisms, such as spring-loaded systems or adjustable shims, to compensate for any inherent backlash.
  • Lubrication: Proper lubrication can reduce friction and play a role in minimizing backlash. Use a lubricant that provides good film strength and reduces wear.
  • Maintenance: Regularly inspect and maintain the gearbox to identify and address any changes in backlash over time.

It’s important to strike a balance between reducing backlash and maintaining smooth operation. Consulting with gearbox experts and following manufacturer guidelines will help you optimize your worm gearbox’s performance while minimizing backlash.

Worm gear reducer gearbox

A worm gear reducer gearbox is a gear reducer gearbox that uses a worm gear train to reduce the required force. Unlike traditional gear reducer gearboxes, these units are small and require low horsepower ratings. This reduces their efficiency, but their low cost and compact design help make up for this shortcoming. However, these gear reducer gearboxes have some drawbacks, including their tendency to lock up when reversing.
worm reducer

high efficiency

High-efficiency worm reducer gearboxes are ideal for applications where high performance, repeatability, and accuracy are critical. It consists of an input hypoid gear and an output hypoid bevel gear. The input worm rotates perpendicular to the output worm, so for every revolution of the input worm, the output gear makes one revolution. This arrangement reduces friction (another source of energy loss) in a high-efficiency worm gear to at least two arc minutes.
Compared with worm gear reducer gearboxes, hypoid gearmotors offer several advantages, including lower operating costs and higher efficiency. For example, hypoid gear motors can transmit more torque even at high reduction ratios. Also, they are more efficient than worm gear reducer gearboxes, which means they can produce the same output with a smaller motor.
In recent years, the efficiency of worm gear reducer gearboxes has been dramatically improved. Manufacturers have made great strides in materials, design, and manufacturing. New designs, including dual-enveloping worm gear reducer gearboxes, increase efficiency by 3 to 8 percent. These improvements were made possible through countless hours of testing and development. Worm gear reducer gearboxes also offer lower initial costs and higher overload capability than competing systems.
Worm gear reducer gearboxes are popular because they provide maximum reduction in a small package. Their compact size makes them ideal for low to medium-horsepower applications and they are reticent. They also offer higher torque output and better shock load tolerance. Finally, they are an economical option to reduce the device’s power requirements.

low noise

Low-noise worm gear reducer gearboxes are designed to reduce noise in industrial applications. This type of reducer gearbox uses fewer bearings and can work in various mounting positions. Typically, a worm reducer gearbox is a single-stage unit with only one shaft and one gear. Since there is only one gear, the noise level of the worm gear reducer gearbox will be lower than other types.
A worm gear reducer gearbox can be integrated into the electric power steering system to reduce noise. Worm reducer gearboxes can be made and from many different materials. The following three-stage process will explain the components of a low-noise worm reducer gearbox.
Worm gear reducer gearboxes can be mounted at a 90-degree angle to the input worm shaft and are available with various types of hollow or solid output shafts. These reducer gearboxes are especially beneficial for applications where noise reduction is essential. They also have fewer parts and are smaller than other types of reducer gearboxes, making them easier to install.
Worm gear reducer gearboxes are available from various manufacturers. Due to their widespread availability, gear manufacturers maintain extensive inventories of these reducer gearboxes. The worm gear ratio is standard, and the size of the worm gear reducer gearbox is universal. Also, worm gear reducer gearboxes do not need to be sized for a specific purpose, unlike other load interruptions.

pocket

A worm gear reducer gearbox is a transmission mechanism with a compact structure, large transmission ratio, and self-locking function under certain conditions. The worm gear reducer gearbox series products are designed with American technology and have the characteristics of stable transmission, strong bearing capacity, low noise, and compact structure. In addition, these products can provide a wide range of power supplies. However, these worm reducer gearboxes are prone to leaks, usually caused by design flaws.
Worm gear reducer gearboxes are available in single-stage and double-stage. The first type consists of an oil tank that houses the worm gear and bearings. The second type uses a worm gear with a sleeve for the first worm gear.
When choosing a gear reducer gearbox, it is essential to choose a high-quality unit. Improper gear selection can cause rapid wear of the worm gear. While worm gear reducer gearboxes are generally durable, their degree of wear depends on the selection and operating conditions. For example, overuse, improper assembly, or working in extreme conditions can lead to rapid wear.
Worm reducer gearboxes reduce speed and torque. Worm gears can be used to reduce the speed of rotating machines or inertial systems. Worm gears are a type of bevel gear, and their meshing surfaces have great sliding force. Because of this, worm gears can carry more weight than spur gears. They are also harder to manufacture. However, the high-quality design of the worm gear makes it an excellent choice for applications requiring high torque and high-speed rotation.
Worm gears can be manufactured using three types of gears. For large reduction ratios, the input and output gears are irreversible. However, the worm reducer gearbox can be constructed with multiple helices. The multi-start worm drive also minimizes braking effects.

Self-locking function

The worm reducer gearbox is self-locking to prevent the load from being driven back to the ground. The self-locking function is achieved by a worm that meshes with the rack and pinion. When the load reaches the highest position, the reverse signal is disabled. The non-locking subsystem back-drives the load to its original position, while the self-locking subsystem remains in its uppermost position.
The self-locking function of the worm reducer gearbox is a valuable mechanical feature. It helps prevent backing and saves the cost of the braking system. Additionally, self-locking worm gears can be used to lift and hold loads.
The self-locking worm gear reducer gearbox prevents the drive shaft from driving backward. It works with the axial force of the worm gear. A worm reducer gearbox with a self-locking function is a very efficient machine tool.
Worm gear reducer gearboxes can be made with two or four teeth. Single-ended worms have a single-tooth design, while double-ended worms have two threads on the cylindrical gear. A multi-boot worm can have up to four boots. Worm reducer gearboxes can use a variety of gear ratios, but the main advantage is their compact design. It has a larger load capacity than a cross-shaft helical gear mechanism.
The self-locking function of the worm reducer gearbox can also be used for gear sets that are not necessarily parallel to the shaft. It also prevents backward travel and allows forward travel. The self-locking function is achieved by a ratchet cam arranged around the gear member. It also enables selective coupling and decoupling between gear members.
worm reducer

high gear ratio

Worm reducer gearboxes are an easy and inexpensive way to increase gear ratios. These units consist of two worm gears – an input worm gear and an output worm gear. The input worm rotates perpendicular to the output worm gear, which also rotates perpendicular to itself. For example, a 5:1 worm gearbox requires 5 revolutions per worm gear, while a 60:1 worm gearbox requires 60 revolutions. However, this arrangement is prone to inefficiency since the worm gear experiences only sliding friction, not rolling friction.
High-reduction applications require many input revolutions to rotate the output gear. Conversely, low input speed applications suffer from the same friction issues, albeit with a different amount of friction. Worms that spin at low speeds require more energy to maintain their movement. Worm reducer gearboxes can be used in many types of systems, but only some are suitable for high-speed applications.
Worm gears are challenging to produce, but the envelope design is the best choice for applications requiring high precision, high efficiency, and minimal backlash. Envelope design involves modifying gear teeth and worm threads to improve surface contact. However, this type of worm gear is more expensive to manufacture.
Worm gear motors have lower initial meshing ratios than hypoid gear motors, which allows the use of smaller motors. So a 1 hp worm motor can achieve the same output as a 1/2 hp motor. A study by Agknx compared two different types of geared motors, comparing their power, torque, and gear ratio. The results show that the 1/2 HP hypoid gear motor is more efficient than the worm gear motor despite the same output.
Another advantage of the worm gear reducer gearbox is the low initial cost and high efficiency. It offers high ratios and high torque in a small package, making it ideal for low to medium-horsepower applications. Worm gear reducer gearboxes are also more shock-resistant.
