High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are perfect for use in applications that demand high repeatability, precise positioning and performance. They were specifically developed for work with with state-of-the-art servo electric motor technology, providing limited integration of the motor to the unit. Angular backlash of less than 1 arc-moments is provided standard.
They are available in four sizes (50 mm to 100 mm center length) with input speeds up 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 for sale to assembly to nearly all servo motors, and the hollow bore output can be utilized to mount outcome shafts, pinion shafts, or other drive elements.
Regular applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and electronic line shafting. Industries served include Material H, ling, Automation, Machine Device, Robotics and Aerospace.
Gearing: Internal gear style was optimized to provide an angular backlash of significantly less than 1 arc-minutes in assembly, with the option of “in the field” adjustable backlash in the event necessary.
Bearings: Input angular contact bearings for high suggestions speed, and robust outcome tapered-roller bearings for superior radial and axial load capability.
Housing: Aluminium 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 provide a line of gadgets to adapt these outputs to right shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-travel reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-traveling the gearmotor so a position can be placed even when power isn’t applied. The precision ground 3/8” stainless steel result shaft is backed by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and metal structure provides a rigid framework without adding unneeded weight and is conveniently attached to any flat work surface by utilizing the bottom mounting tabs. Our Standard Spur Gear motors will work with this gearbox (motor distributed separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse devices and low-swiftness applications that want high precision and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (at max speed)
now provides an economical right position gearhead for work with with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers are most appropriate for basic motion and source speeds of 2000 rpm where profile program costs certainly are a major consideration.

Worm Gears are right angle drives providing large speed ratios on comparatively short center distances from 1/4” to 11”. When correctly attached and lubricated they function as the quietist and smoothest running type of gearing. Due to the high ratios conceivable with worm gearing, optimum speed reduction can be accomplished in less space than a great many other types of gearing. Worm and worm gears operate on non-intersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a big level on the helix position of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% better than solo thread worms. The mesh or engagement of worms with worm gears creates a sliding action triggering considerable friction and increased loss of efficiency beyond other styles of gearing. The usage of hardened and ground worm swith bronze worm gears rises efficiency.
LUBRICATION can be an essential factor to boost efficiency in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. The quantity of vitality transmitted at confirmed temperature increases as the proficiency of the gearing rises. Proper lubrication enhances efficiency by reducing friction and heat.
RATIOS of worm equipment sets are dependant on dividing the amount of teeth in the apparatus by the number of threads. Thus solitary threads yield larger ratios than multiple threads. All EP. worm gear sets can be found with either left or right palm threads. EP. worm equipment sets are offered with Single, Double, Triple 
and Qua-druple Threads.
Safe practices PROVISION: Worm gearing should not be used as a good locking mechanism to hold heavy weights where reversing actions could cause harm or personal injury. In applications where potential harm is non-existent and self-locking is desired against backward rotation then use of a single thread worm with a minimal helix angle quickly locks the worm equipment travel against backward rotation.
MATERIAL recommended for worms is normally hardened steel and bronze for worm gears. However, depending on the application unhardened steel worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms can be purchased in bronze, stainless, aluminium and nylon; worm gears can be purchased in steel, hardened metal, stainless, light weight aluminum, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring devices called GEAR GAGES! Gear Gages decrease mistakes, save money and time when identifying and ordering gears. These pitch templates can be purchased in nine sets to recognize all the normal pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Fine Pitches, Coarse Pitches and Unusual Pitches. Make reference to the section on Equipment GAGES for catalog quantities when ordering.
