High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are perfect for use in applications that demand high performance, precise positioning and repeatability. They were especially developed for use with state-of-the-art servo motor technology, providing limited integration of the motor to the machine. Angular backlash of less than 1 arc-minutes is provided standard.
They can be purchased in four sizes (50 mm to 100 mm center distance) with input boosts to 5,000 rpm, reduction ratios from 4.75 to 52:1 and output torque capacities up to 885 lb.ft. A wide selection of electric motor couplings and mounting flanges are available for assembly to almost all servo motors, and the hollow bore outcome can be utilised to mount output shafts, pinion shafts, or other drive elements.
Typical applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and digital line shafting. Industries dished up include Material H, ling, Aerospace, Robotics, Automation and Machine Tool.
Gearing: Internal gear style was optimized to provide an angular backlash of significantly less than 1 arc-minutes at assembly, with the choice of “in the field” adjustable backlash if necessary.
Bearings: Input angular contact bearings for high suggestions speed, and robust result tapered-roller bearings for great radial and axial load potential.
Housing: Light weight aluminum housing for good heat dissipation, with integral suggestions flange for servo motors and general mounting on any deal with.
Output: The end result bore is available with a compression-type hub or a ISO 9409-1 flange (see dimension pages). We give you a line of gadgets to adjust these outputs to straight shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but also eliminates back-generating the gearmotor so a posture can be held even when power is not applied. The precision surface 3/8” stainless steel productivity shaft is supported by dual 3/8” ABEC 5 ball bearings to support a load from any orientation. The ¼” ABS plastic and metal structure provides a rigid framework without adding pointless weight and is quickly installed to any flat surface by utilizing the bottom mounting tabs. Our Regular Spur Gear motors will work with this gearbox (motor offered separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-speed applications that want high accuracy and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (in max speed)
now offers an economical right position gearhead for use with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers are most appropriate for basic action and insight speeds of 2000 rpm where profile software costs certainly are a major consideration.

Worm Gears are right angle drives providing large swiftness ratios on comparatively short center distances from 1/4” to 11”. When effectively mounted and lubricated they function as the quietist and smoothest operating type of gearing. Due to the high ratios conceivable with worm gearing, maximum speed reduction could be accomplished in much less space than a great many other types of gearing. Worm and worm gears operate on nonintersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a big degree on the helix position of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% more efficient than solitary thread worms. The mesh or engagement of worms with worm gears makes a sliding action leading to considerable friction and increased loss of efficiency beyond other types of gearing. The use of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to boost efficiency in worm gearing. Worm gear action generates considerable warmth, decreasing efficiency. How much electricity transmitted at a given temperature raises as the proficiency of the gearing increases. Proper lubrication enhances proficiency by reducing friction and heat.
RATIOS of worm gear sets are dependant on dividing the quantity of teeth in the apparatus by the number of threads. Thus solitary threads yield higher ratios than multiple threads. All EP. worm equipment sets are available with either left or right side threads. EP. worm gear sets are offered with Triple, Qua, Sole and Double-druple Threads.
Protection PROVISION: Worm gearing should not be used as a good locking mechanism to carry large weights where reversing action could cause harm or personal injury. In applications where potential injury is non-existent and self-locking is preferred against backward rotation in that case use of an individual thread worm with a low helix angle quickly locks the worm gear drive against backward rotation.
Materials recommended for worms is definitely hardened steel and bronze for worm gears. On the other hand, depending on the application unhardened metal worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms can be found in bronze, aluminium, stainless and nylon; worm gears are available in steel, hardened steel, stainless, light weight aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring devices called GEAR GAGES! Gear Gages lessen mistakes, save time and money when identifying and purchasing gears. These pitch templates can be purchased in nine sets to recognize all the regular pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Great Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on GEAR GAGES for catalog quantities when ordering.

There is excellent worth in taking time to understand the subject of Servo Worm Reducer, however the Net might or may not be your ideal resource of information.
