High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are perfect for use in applications that demand high precise positioning, repeatability and performance. They were especially developed for employ with state-of-the-art servo electric motor technology, providing tight integration of the motor to the unit. Angular backlash of significantly less than 1 arc-moments is provided standard.
They are available in four sizes (50 mm to 100 mm center range) 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 engine couplings and mounting flanges are for sale to assembly to nearly all servo motors, and the hollow bore productivity can be used to mount end result shafts, pinion shafts, or other drive elements.
Normal applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and electronic digital line shafting. Industries dished up include Material H, Automation, ling, Robotics, Machine Device and Aerospace.
Gearing: Internal gear style was optimized to supply an angular backlash of significantly less than 1 arc-minutes in assembly, with the option of “in the field” adjustable backlash in the event that necessary.
Bearings: Input angular contact bearings for high insight speed, and robust end result tapered-roller bearings for great radial and axial load capacity.
Housing: Light weight aluminum housing for good heat dissipation, with essential insight flange for servo motors and general mounting on any deal with.
Output: The result bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension pages). We offer 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 merely minimizes backlash but as well eliminates back-traveling the gearmotor so a posture can be placed even when power isn’t applied. The precision surface 3/8” stainless steel output shaft is backed by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and metal structure provides a rigid framework without adding unnecessary weight and is quickly attached to any flat surface by utilizing the bottom mounting tabs. Our Typical Spur Gear motors will work with this gearbox (electric motor marketed separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse devices and low-acceleration applications that want high precision and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (at max speed)
now provides an economical right position gearhead for employ with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers happen to be most appropriate for basic motion and source speeds of 2000 rpm where profile software costs certainly are a major consideration.

Worm Gears are best suited angle drives providing large quickness ratios on comparatively short center distances from 1/4” to 11”. When correctly attached and lubricated they function as quietist and smoothest jogging type of gearing. Because of the high ratios likely with worm gearing, optimum speed reduction can be accomplished in less space than a great many other types of gearing. Worm and worm gears are powered by non-intersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a large level on the helix position of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% better than sole thread worms. The mesh or engagement of worms with worm gears generates a sliding action creating considerable friction and better loss of efficiency beyond other styles of gearing. The usage of hardened and surface worm swith bronze worm gears boosts efficiency.
LUBRICATION can be an essential factor to boost efficiency in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The amount of ability transmitted at confirmed temperature rises as the productivity of the gearing boosts. Proper lubrication enhances proficiency by reducing friction and heat.
RATIOS of worm equipment sets are dependant on dividing the amount of teeth in the gear by the number of threads. Thus single threads yield larger ratios than multiple threads. All EP. worm equipment sets are available with either still left or right hands threads. EP. worm equipment sets can be found with Qua, Triple, Double and Single-druple Threads.
Basic safety PROVISION: Worm gearing should not be used as a locking mechanism to hold heavy weights where reversing actions could cause harm or damage. In applications where potential harm is nonexistent and self-locking is wanted against backward rotation in that case use of a single thread worm with a minimal helix angle immediately locks the worm equipment travel against backward rotation.
Materials recommended for worms is certainly hardened steel and bronze for worm gears. Even so, depending on the application form unhardened steel worms operate adequately and extra economically with cast iron worm gears at 50% horsepower ratings. In addition to metal and hardenedsteel, worms can be found in aluminium, bronze, nylon and stainless; worm gears can be purchased in steel, hardened metal, stainless, aluminium, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring units called GEAR GAGES! Gear Gages reduce mistakes, save money and time when identifying and ordering gears. These pitch templates can be found in nine sets to recognize all the common pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Unusual Pitches. Make reference to the section on Equipment GAGES for catalog quantities when ordering.
