High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are simply perfect for use in applications that demand high repeatability, precise positioning and performance. They were especially developed for make use of with state-of-the-art servo engine technology, providing limited integration of the motor to the unit. Angular backlash of less than 1 arc-mins 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 range of engine couplings and mounting flanges are available for assembly to nearly all servo motors, and the hollow bore outcome works extremely well to mount output 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 dished up include Material H, Automation, ling, Robotics, Aerospace and Machine Tool.
Gearing: Internal gear design was optimized to provide an angular backlash of significantly less than 1 arc-minutes in assembly, with the option of “in the field” adjustable backlash if necessary.
Bearings: Input angular call bearings for high type speed, and robust result tapered-roller bearings for high radial and axial load potential.
Housing: Aluminium housing for good heat dissipation, with essential insight flange for servo motors and general mounting on any deal with.
Output: The productivity bore is available with a good compression-type hub or a good ISO 9409-1 flange (see dimension web pages). We give a line of extras 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 as well eliminates back-generating the gearmotor so a position can be placed even when power is not applied. The precision ground 3/8” stainless steel productivity shaft is reinforced by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and lightweight aluminum structure provides a rigid framework without adding unnecessary weight and is conveniently attached to any flat work surface by utilizing the bottom mounting tabs. Our Standard Spur Gear motors will work with this gearbox (engine sold separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse systems and low-acceleration applications that want high precision and torque.
Motor RPM required = 1 / (a few minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (at max speed)
now offers an economical right angle gearhead for make use of with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers will be best suited for basic action and source speeds of 2000 rpm where profile software costs are a major consideration.

Worm Gears are best angle drives providing large acceleration ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as the quietist and smoothest operating type of gearing. Because of the high ratios feasible with worm gearing, optimum speed reduction can be accomplished in less space than a great 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 sizable extent on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better than solo thread worms. The mesh 
or engagement of worms with worm gears generates a sliding action causing considerable friction and greater loss of efficiency beyond other types of gearing. The utilization of hardened and surface worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to boost efficiency found in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The quantity of ability transmitted at confirmed temperature rises as the efficiency of the gearing increases. Proper lubrication enhances performance by lowering friction and heat.
RATIOS of worm gear sets are dependant on dividing the quantity of teeth in the apparatus by the amount of threads. Thus solitary threads yield larger ratios than multiple threads. All EP. worm gear sets are available with either still left or right hands threads. EP. worm gear sets are offered with Qua, One, Triple and Double-druple Threads.
Safeness PROVISION: Worm gearing should not be used as a good locking mechanism to hold heavy weights where reversing actions could cause harm or harm. In applications where potential damage is non-existent and self-locking is preferred against backward rotation then use of a single thread worm with a minimal helix angle instantly locks the worm gear travel against backward rotation.
Materials recommended for worms is normally hardened steel and bronze for worm gears. However, 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 are available in bronze, stainless, aluminum and nylon; worm gears are available in steel, hardened steel, stainless, light weight aluminum, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring products called Equipment GAGES! Gear Gages lessen mistakes, save money and time when identifying and purchasing gears. These pitch templates are available in nine sets to identify all the regular pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Great Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on Equipment GAGES for catalog amounts when ordering.
