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 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-moments 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 range of motor couplings and mounting flanges are for sale to assembly to almost all servo motors, and the hollow bore productivity 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, Aerospace, Robotics 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 insight flange for servo motors and common mounting on any encounter.
Output: The end result bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension webpages). We give you a line of accessories to adjust 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 likewise eliminates back-traveling the gearmotor so a position can be kept even when power isn’t applied. The precision ground 3/8” stainless steel output shaft is reinforced by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and aluminium structure provides a rigid framework without adding unneeded weight and is very easily attached to any flat 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 want high precision and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (in max speed)
now provides an economical right angle gearhead for work with with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers happen to be most appropriate for basic action and input speeds of 2000 rpm where profile software costs are a major consideration.

Worm Gears are ideal angle drives providing huge velocity ratios on comparatively short center distances from 1/4” to 11”. When correctly attached and lubricated they function as the quietist and smoothest operating type of gearing. As a result of high ratios likely 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 equipment drives depends to a big level on the helix position of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than solo thread worms. The mesh or engagement of worms with worm gears creates 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 equipment action generates considerable high temperature, decreasing efficiency. The number of electricity transmitted at a given temperature boosts as the productivity of the gearing increases. Proper lubrication enhances productivity by lowering friction and heat.
RATIOS of worm gear sets are determined by dividing the number of teeth in the apparatus by the amount of threads. Thus solo threads yield higher 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 Solitary, Triple, Double 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 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 quickly locks the worm equipment 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 metal and hardenedsteel, worms are available in nylon, stainless, bronze and aluminum; worm gears are available in steel, hardened steel, stainless, metal, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring gadgets called GEAR GAGES! Gear Gages lessen mistakes, save time and money when identifying and ordering gears. These pitch templates are available in nine sets to identify all the typical 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.
