worm gear speed reducer
Solitary reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are reduced to gradual speed requirements of many industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened floor and polished alloy metal worm develops a simple, work hardened surface area on the bronze gear. Because of this worm gears use in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower levels than are possible with regular cast iron devices. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the gear under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s acceleration reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy steel worm. This mixture develops a easy, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and allows for the likelihood of large acceleration reductions. These gears can be found from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The small design and construction allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with some other types of gearing.
The usage of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear container which includes a worm pinion insight, an output worm gear, and includes a right angle result orientation. This kind of reduction gear container is generally used to have a rated motor swiftness and create a low speed result with higher torque value based on the reduction ratio. They often times can resolve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of acceleration reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems make use of a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical screening equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm equipment reducer, the SW-1 and the SW-5 and both are available in a variety of ratios. The SW-1 ratios include 3.5:1 to 60:1 and the SW-5 ratios include 5:1 to 100:1. Both these options are manufactured with tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm speed reducers. Worm gear reducers are used for speed decrease and raising the torque for electric motor drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you want a coupling for the output or input shaft observe our coupling section for selecting a coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore output. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will need to determine the required torque and provider factor for the application form. Click on “Specifications” above for a table that will aid in identifying the service factor. For service factors above 1.0, multiply the required torque by the provider factor.
