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 specifically developed for make use of with state-of-the-art servo electric motor technology, providing restricted integration of the electric 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 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 engine couplings and mounting flanges are for sale to assembly to virtually all servo motors, and the hollow bore outcome can be utilised to mount productivity shafts, pinion shafts, or other drive elements.
Typical 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 dished up include Material H, ling, Machine Application, Robotics, Automation and Aerospace.
Gearing: Internal gear design was optimized to supply an angular backlash of significantly less than 1 arc-minutes at assembly, with the choice of “in the discipline” adjustable backlash in the event necessary.
Bearings: Input angular contact bearings for high insight speed, and robust result tapered-roller bearings for high radial and axial load ability.
Housing: Aluminium housing once and for all heat dissipation, with integral input flange for servo motors and universal mounting on any encounter.
Output: The output bore is available with a compression-type hub or a ISO 9409-1 flange (see dimension webpages). We offer a line of add-ons to adjust these outputs to direct shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-traveling the gearmotor so a position can be placed even when power is not applied. The precision floor 3/8” stainless steel output shaft is supported by dual 3/8” ABEC 5 ball bearings to support a load from any orientation. The ¼” ABS plastic and aluminum structure offers a rigid framework without adding unneeded weight and is very easily installed to any flat work surface by utilizing the bottom mounting tabs. Our Standard Spur Gear motors will work with this gearbox (engine marketed separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse systems and low-speed applications that want high accuracy 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 ten minutes per rotation (in max speed)
now offers an economical right angle gearhead for make use of with small NEMA 23 through 56 and similar small metric servo and stepper motors. These reducers will be most appropriate for basic motion and insight speeds of 2000 rpm where profile program costs are a major consideration.

Worm Gears are best angle drives providing significant rate ratios on comparatively brief center distances from 1/4” to 11”. When correctly mounted and lubricated they function as the quietist and smoothest working type of gearing. Due to the high ratios practical with worm gearing, optimum speed reduction could be accomplished in fewer space than a great 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 sizable level on the helix angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% more efficient than sole thread worms. The mesh or engagement of worms with worm gears makes a sliding action creating considerable friction and better loss of efficiency beyond other types of gearing. The use of hardened and surface worm swith bronze worm gears boosts efficiency.
LUBRICATION can be an essential factor to boost efficiency found in worm gearing. Worm gear action generates considerable warmth, decreasing efficiency. The quantity of vitality transmitted at a given temperature increases as the performance of the gearing boosts. Proper lubrication enhances productivity by minimizing friction and heat.
RATIOS of worm equipment sets are determined by dividing the number of teeth in the apparatus by the amount of threads. Thus one threads yield bigger ratios than multiple threads. All EP. worm equipment sets can be found with either still left or right side threads. EP. worm equipment sets can be found with Qua, Solitary, Double and Triple-druple Threads.
Basic safety PROVISION: Worm gearing should not be used as a locking mechanism to hold large weights where reversing action could cause harm or injury. In applications where potential harm is non-existent and self-locking is preferred against backward rotation after that use of a single thread worm with a low helix angle immediately locks the worm gear travel against backward rotation.
MATERIAL recommended for worms is hardened steel and bronze for worm gears. On the other hand, depending on the application form unhardened metal worms operate adequately and extra economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms can be found in aluminium, nylon, bronze and stainless; worm gears are available in steel, hardened metal, stainless, metal, nylon and nonmetallic (phenolic).
EP also sells gear tooth measuring units called GEAR GAGES! Gear Gages decrease mistakes, save money and time when identifying and purchasing gears. These pitch templates can be purchased in nine sets to recognize all the normal pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Great Pitches, Coarse Pitches and Uncommon Pitches. Make reference to the section on GEAR GAGES for catalog numbers when ordering.
