High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are simply perfect for use in applications that demand high repeatability, precise positioning and performance. They were specifically developed for make use of with state-of-the-art servo engine technology, providing tight integration of the electric motor to the machine. Angular backlash of less than 1 arc-mins is provided standard.
They can be purchased in four sizes (50 mm to 100 mm center distance) 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 practically all servo motors, and the hollow bore productivity can be utilized to mount result shafts, pinion shafts, or other drive elements.
Usual 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 offered include Material H, Automation, ling, Aerospace, Robotics and Machine Tool.
Gearing: Internal gear style was optimized to provide an angular backlash of less than 1 arc-minutes in assembly, with the option of “in the discipline” adjustable backlash if necessary.
Bearings: Input angular contact bearings for high input speed, and robust result tapered-roller bearings for great radial and axial load potential.
Housing: Aluminium housing once and for all heat dissipation, with essential type flange for servo motors and universal mounting on any face.
Output: The result bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension internet pages). We give you a line of components to adapt these outputs to straight shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-travel reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but likewise eliminates back-driving the gearmotor so a posture can be held even when power isn’t applied. The precision surface 3/8” stainless steel result shaft is backed by dual 3/8” ABEC 5 ball bearings to aid a load from any orientation. The ¼” ABS plastic and light weight aluminum structure provides a rigid framework without adding needless weight and is conveniently installed to any flat work surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will work with this gearbox (motor marketed separately). The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-acceleration applications that require high accuracy and torque.
Motor RPM required = 1 / (minutes per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (in max speed)

Worm Gears are ideal angle drives providing large speed ratios on comparatively short center distances from 1/4” to 11”. When correctly attached and lubricated they function as quietist and smoothest working type of gearing. Due to high ratios likely with worm gearing, maximal speed reduction can be accomplished in much less space than many other types of gearing. Worm and worm gears operate on non-intersecting shafts at 90° angles.
EFFICIENCY of worm gear 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 sole thread worms. The mesh or engagement of worms with worm gears produces a sliding action leading to considerable friction and higher lack of efficiency beyond other styles of gearing. The make use of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to boost efficiency found in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The quantity of power transmitted at confirmed temperature boosts as the performance of the gearing boosts. Proper lubrication enhances productivity by reducing friction and heat.
RATIOS of worm gear sets are determined by dividing the quantity of teeth in the gear by the number of threads. Thus one threads yield larger ratios than multiple threads. All EP. worm equipment sets are available with either still left or right hands threads. EP. worm gear sets can be found with Triple, Double, Qua and Single-druple Threads.
Security 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 harm is nonexistent and self-locking is desired against backward rotation then use of a single thread worm with a low helix angle instantly locks the worm equipment drive against backward rotation.
MATERIAL recommended for worms is usually hardened steel and bronze for worm gears. Nevertheless, depending on the application unhardened metal worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms can be found in bronze, stainless, nylon and aluminum; worm gears can be found in steel, hardened steel, stainless, aluminum, nylon and nonmetallic (phenolic).
EP also sells equipment tooth measuring devices called Equipment GAGES! Gear Gages lessen mistakes, save time and money when identifying and ordering gears. These pitch templates can be found in nine sets to recognize all the normal pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on Equipment GAGES for catalog amounts when ordering.
