High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are simply perfect for use in applications that demand high repeatability, performance and precise positioning. They were especially developed for make use of with state-of-the-art servo engine technology, providing restricted integration of the motor to the machine. Angular backlash of significantly less than 1 arc-a few 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 wide variety of engine couplings and mounting flanges are available for assembly to virtually all servo motors, and the hollow bore outcome can be utilised to mount result 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, Machine Application, Robotics and Aerospace.
Gearing: Internal gear design was optimized to provide an angular backlash of significantly less than 1 arc-minutes at assembly, with the option of “in the field” adjustable backlash in the event that necessary.
Bearings: Input angular call bearings for high type speed, and robust result tapered-roller bearings for large radial and axial load capacity.
Housing: Light weight aluminum housing once and for all heat dissipation, with essential suggestions flange for servo motors and universal mounting on any deal with.
Output: The productivity bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension internet pages). We give a line of accessories to adapt these outputs to direct shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-get reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-generating the gearmotor so a position can be placed even when power is not applied. The precision floor 3/8” stainless steel output shaft is reinforced by dual 3/8” ABEC 5 ball bearings to support a load from any orientation. The ¼” ABS plastic and metal structure provides a rigid framework without adding unneeded weight and is easily mounted to any flat work surface by utilizing the bottom mounting tabs. Our Regular Spur Gear motors will work with this gearbox (electric motor offered separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse systems and low-swiftness applications that require high precision and torque.
Motor RPM required = 1 / (minutes 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 angle gearhead for employ with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers will be best suited for basic motion and input speeds of 2000 rpm where profile program costs certainly are a major consideration.

Worm Gears are best angle drives providing large swiftness ratios on comparatively short center distances from 1/4” to 11”. When correctly mounted and lubricated they function as quietist and smoothest operating type of gearing. Because of the 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 are powered by non-intersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a large extent on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% more efficient than single thread worms. The mesh or engagement of worms with worm gears creates a sliding action leading to considerable friction and higher loss of efficiency beyond other styles of gearing. The utilization of hardened and surface worm swith bronze worm gears raises efficiency.
LUBRICATION can be an essential factor to boost efficiency found in worm gearing. Worm gear action generates considerable heat, decreasing efficiency. The number of vitality transmitted at confirmed temperature increases as the effectiveness of the gearing increases. Proper lubrication enhances productivity by reducing 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 one threads yield larger ratios than multiple threads. All EP. worm equipment sets can be found with either still left or right hands threads. EP. worm gear sets are offered with Solo, Double, Qua and Triple-druple Threads.
SAFETY PROVISION: Worm gearing should not be used as a good locking mechanism to hold heavy weights where reversing actions can cause harm or injury. In applications where potential damage is non-existent and self-locking is preferred against backward rotation after that use of a single thread worm with a minimal helix angle instantly locks the worm equipment travel against backward rotation.
Materials recommended for worms is normally hardened steel and bronze for worm gears. Nevertheless, depending on the application form unhardened steel worms operate adequately and extra economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms can be found in bronze, nylon, lightweight aluminum and stainless; worm gears can be found in steel, hardened metal, stainless, lightweight aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring gadgets called Equipment GAGES! Gear Gages lessen mistakes, save money and time when identifying and buying gears. These pitch templates are available in nine sets to recognize all the common pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on Equipment GAGES for catalog quantities when ordering.

While others have discussed the topic of Servo Worm Reducer, my hope is that this write-up brings a distinct viewpoint.
