High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are exquisite for use in applications that demand high repeatability, precise positioning and performance. They were especially developed for work with with state-of-the-art servo motor technology, providing limited integration of the electric motor to the machine. Angular backlash of significantly less than 1 arc-moments is provided standard.
They are available in four sizes (50 mm to 100 mm center length) 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 variety of engine couplings and mounting flanges are for sale to assembly to virtually all servo motors, and the hollow bore productivity works extremely well to mount end result shafts, pinion shafts, or other drive elements.
Standard applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives, zero-backlash axis drives and electric line shafting. Industries served include Material H, ling, Machine Program, Automation, Robotics and Aerospace.
Gearing: Internal gear design was optimized to provide an angular backlash of significantly less than 1 arc-minutes in assembly, with the option of “in the discipline” adjustable backlash if necessary.
Bearings: Input angular call bearings for high input speed, and robust end result tapered-roller bearings for superior radial and axial load ability.
Housing: Light weight aluminum housing for good heat dissipation, with essential type flange for servo motors and universal mounting on any deal with.
Output: The productivity bore is available with a compression-type hub or a ISO 9409-1 flange (see dimension pages). We give you a line of equipment to adapt these outputs to straight shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but as well eliminates back-driving the gearmotor so a posture can be placed even when power is not applied. The precision floor 3/8” stainless steel result shaft is reinforced by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and lightweight aluminum structure offers a rigid framework without adding needless weight and is very easily installed to any flat surface by utilizing the bottom mounting tabs. Our Regular Spur Gear motors will continue to work with this gearbox (electric motor purchased separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse systems and low-swiftness applications that require high accuracy and torque.
Motor RPM required = 1 / (a few minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve ten minutes per rotation (in max speed)
now provides an economical right angle gearhead for work with with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers will be most appropriate for basic action and insight speeds of 2000 rpm where profile program costs certainly are a major consideration.

Worm Gears are best suited angle drives providing large acceleration ratios on comparatively short center distances from 1/4” to 11”. When properly attached and lubricated they function as the quietist and smoothest running type of gearing. Because of the high ratios possible with worm gearing, maximal speed reduction could be accomplished in fewer space than many other types of gearing. Worm and worm gears are powered by nonintersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a large extent on the helix position of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than one thread worms. The mesh or engagement of worms with worm gears generates a sliding action triggering considerable friction and increased loss of efficiency beyond other styles of gearing. The use of hardened and ground worm swith bronze worm gears raises efficiency.
LUBRICATION can be an essential factor to improve efficiency found in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The number of electricity transmitted at a given temperature boosts as the efficiency of the gearing rises. Proper lubrication enhances proficiency by minimizing friction and heat.
RATIOS of worm equipment sets are determined by dividing the quantity of teeth in the gear by the number of threads. Thus sole threads yield higher ratios than multiple threads. All EP. worm equipment sets are available with either left or right palm threads. EP. worm equipment sets are offered with Solo, Qua, Double and Triple-druple Threads.
Safeness PROVISION: Worm gearing should not be used as a locking mechanism to carry heavy weights where reversing action can cause harm or damage. In applications where potential damage is non-existent and self-locking is wanted against backward rotation then use of an individual thread worm with a minimal helix angle instantly locks the worm gear get against backward rotation.
MATERIAL recommended for worms is usually hardened steel and bronze for worm gears. On the other hand, depending on the application form unhardened steel worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms can be found in aluminium, bronze, stainless and nylon; worm gears can be purchased in steel, hardened steel, stainless, light weight aluminum, nylon and nonmetallic (phenolic).
EP also sells equipment tooth measuring units called GEAR GAGES! Gear Gages reduce mistakes, save money and time when identifying and buying gears. These pitch templates can be found in nine sets to recognize all the typical pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on GEAR GAGES for catalog figures when ordering.
