High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are ideal for use in applications that demand high precise positioning, repeatability and performance. They were particularly developed for use with state-of-the-art servo engine technology, providing restricted 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 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 broad range of motor couplings and mounting flanges are for sale to assembly to almost all servo motors, and the hollow bore outcome can be utilized to mount outcome 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 served include Material H, Automation, ling, Robotics, Aerospace and Machine Tool.
Gearing: Internal gear style was optimized to supply 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 type speed, and robust output tapered-roller bearings for great radial and axial load capability.
Housing: Light weight aluminum housing once and for all heat dissipation, with essential input flange for servo motors and common mounting on any face.
Output: The end result bore is available with a good compression-type hub or a good ISO 9409-1 flange (see dimension webpages). We provide a line of accessories to adapt these outputs to right shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-get reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but also eliminates back-driving the gearmotor so a position can be kept even when power isn’t applied. The precision surface 3/8” stainless steel output shaft is reinforced by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and aluminium structure provides a rigid framework without adding unneeded weight and is easily installed to any flat work surface by utilizing the bottom mounting tabs. Our Common Spur Gear motors will work with this gearbox (motor distributed separately). The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse systems and low-acceleration applications that require high precision and torque.

Worm Gears are ideal angle drives providing huge 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. As a result of high ratios feasible with worm gearing, optimum speed reduction can 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 gear drives depends to a big degree on the helix angle of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better than sole thread worms. The mesh or engagement of worms with worm gears generates a sliding action leading to considerable friction and greater loss of efficiency beyond other styles of gearing. The make use of hardened and ground worm swith bronze worm gears boosts efficiency.
LUBRICATION is an essential factor to boost efficiency in worm gearing. Worm gear action generates considerable high temperature, decreasing efficiency. The number of electric power transmitted at a given temperature boosts as the performance of the gearing increases. Proper lubrication enhances productivity by lowering friction and heat.
RATIOS of worm gear sets are dependant on dividing the number of teeth in the gear by the amount of threads. Thus solo threads yield bigger ratios than multiple threads. All EP. worm gear sets can be found with either left or right side threads. EP. worm gear sets can be found with Single, Double, Triple and Qua-druple Threads.
Safe practices PROVISION: Worm gearing shouldn’t be used as a locking mechanism to carry heavy weights where reversing actions could cause harm or personal injury. In applications where potential injury is nonexistent and self-locking is preferred against backward rotation in that case use of a single thread worm with a minimal helix angle immediately locks the worm gear drive against backward rotation.
Materials recommended for worms is usually hardened steel and bronze for worm gears. Nevertheless, depending on the application form unhardened steel worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. In addition to steel and hardenedsteel, worms can be purchased in nylon, bronze, lightweight aluminum and stainless; worm gears are available in steel, hardened steel, stainless, lightweight aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring gadgets called GEAR GAGES! Gear Gages lessen mistakes, save money and time when identifying and buying gears. These pitch templates can be purchased in nine sets to identify all the normal 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.
