High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are ideal for use in applications that demand high repeatability, precise positioning and performance. They were especially developed for work with with state-of-the-art servo motor technology, providing tight integration of the engine to the machine. Angular backlash of significantly less than 1 arc-a few minutes is provided standard.
They are available in four sizes (50 mm to 100 mm center distance) 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 virtually all servo motors, and the hollow bore productivity works extremely well to mount result 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 digital line shafting. Industries offered include Material H, ling, Machine Program, Automation, Aerospace and Robotics.
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 field” adjustable backlash in the event that necessary.
Bearings: Input angular contact bearings for high suggestions speed, and robust result tapered-roller bearings for large radial and axial load potential.
Housing: Light weight aluminum housing once and for all heat dissipation, with integral type flange for servo motors and general mounting on any face.
Output: The end result bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension internet pages). We offer a line of components to adjust these outputs to straight 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 only minimizes backlash but likewise eliminates back-generating the gearmotor so a posture can be kept even when power isn’t applied. The precision ground 3/8” stainless steel result shaft is supported by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and metal structure offers a rigid framework without adding pointless weight and is very easily installed to any flat work surface by utilizing the base mounting tabs. Our Common Spur Gear motors will work with this gearbox (electric motor purchased separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse devices and low-velocity applications that require high precision and torque.
Motor RPM required = 1 / (minutes 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 movement and source speeds of 2000 rpm where profile application costs are a major consideration.

Worm Gears are ideal angle drives providing significant speed ratios on comparatively short center distances from 1/4” to 11”. When correctly installed and lubricated they function as quietist and smoothest jogging type of gearing. Due to high ratios practical with worm gearing, maximal speed reduction could be accomplished in fewer space than a great many other types of gearing. Worm and worm gears operate on nonintersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a large level on the helix position of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% more efficient than solo thread worms. The mesh or engagement of worms with worm gears generates a sliding action leading to considerable friction and greater lack of efficiency beyond other types of gearing. The use of hardened and surface worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to boost efficiency found in worm gearing. Worm equipment action generates considerable high temperature, decreasing efficiency. The quantity of electric power transmitted at confirmed temperature increases 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 quantity of teeth in the apparatus by the number of threads. Thus single threads yield larger ratios than multiple threads. All EP. worm gear sets are available with either still left or right hands threads. EP. worm equipment sets are offered with Triple, Sole, Double and Qua-druple Threads.
Security PROVISION: Worm gearing shouldn’t be used as a good locking mechanism to carry large weights where reversing action could cause harm or injury. In applications where potential harm is non-existent and self-locking is desired against backward rotation after that use of a single thread worm with a minimal helix angle instantly locks the worm gear drive against backward rotation.
Materials recommended for worms is usually hardened steel and bronze for worm gears. However, depending on the application unhardened metal worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. In addition to steel and hardenedsteel, worms can be purchased in aluminium, stainless, nylon and bronze; worm gears can be purchased in steel, hardened steel, stainless, aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring equipment called Equipment GAGES! Gear Gages reduce mistakes, save time and money when identifying and purchasing gears. These pitch templates can be purchased in nine sets to identify all the normal 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 amounts when ordering.
