EP offers a complete selection of modular servo gearboxes /worm reducers. The modular style permits configurations with motor type flange and result pinion for rack and pinion drives, and also solid result shafts, Hollow bore productivity, and suggestions shafts for all other positioning applications. The modular style allows for common mounting of the gearbox in virtually any orientation.
Servo-Worm Reducers were particularly developed for work with with the most recent servo motors in applications that demand specific positioning and repeatability.
These reducers are suited to applications in material handling, automation, equipment tool, and robotics.
The light-weight modular aluminum housing design permits easy machine integration, and excellent heat dissipation. A multitude of source flanges and couplings can be found to permit easy mounting of almost any servo-motor and custom flanges could be accommodated. Output configurations with pinion, hollow bore, or sturdy shaft are available and may be configured for insight with motor flange, free of charge insight shaft, or both free of charge input shaft and electric motor flange.
An optimized worm equipment tooth design insures excessive efficiency while at exactly the same time decreasing backlash. Two degrees of backlash can be found, Precise or Extra-precise, with backlash amounts to less than 3 arc minutes.

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 particularly developed for employ with state-of-the-art servo motor technology, providing limited integration of the engine 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 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 wide variety of motor couplings and mounting flanges are for sale to assembly to nearly all servo motors, and the hollow bore result 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, Robotics, Machine Instrument, Automation and Aerospace.
Gearing: Internal gear style was optimized to provide an angular backlash of less than 1 arc-minutes at assembly, with the option of “in the discipline” adjustable backlash in the event necessary.
Bearings: Input angular get in touch with bearings for high insight speed, and robust output tapered-roller bearings for large radial and axial load capability.
Housing: Aluminium housing for good heat dissipation, with integral insight flange for servo motors and universal mounting on any face.
Output: The result bore is available with a good compression-type hub or a good ISO 9409-1 flange (see dimension pages). We give you a line of extras to adjust these outputs to straight 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 only minimizes backlash but likewise eliminates back-generating the gearmotor so a posture can be kept even when power is not applied. The precision ground 3/8” stainless steel end result shaft is supported by dual 3/8” ABEC 5 ball bearings to support a load from any orientation. The ¼” ABS plastic and aluminium structure provides a rigid framework without adding unneeded weight and is conveniently attached to any flat surface by utilizing the base mounting tabs. Our Normal Spur Gear motors will work with this gearbox (engine offered separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse systems and low-acceleration 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 needed to achieve ten minutes per rotation (at max speed)
now provides an economical right position gearhead for employ with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers are most appropriate for basic movement and suggestions speeds of 2000 rpm where profile program costs are a major consideration.

Worm Gears are best suited angle drives providing significant rate ratios on comparatively short center distances from 1/4” to 11”. When correctly installed and lubricated they function as the quietist and smoothest operating type of gearing. As a result of 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 degree on the helix angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than solitary thread worms. The mesh or engagement of worms with worm gears generates a sliding action causing considerable friction and better loss of efficiency beyond other styles of gearing. The usage of hardened and surface worm swith bronze worm gears rises efficiency.
LUBRICATION can be an essential factor to improve efficiency in worm gearing. Worm gear action generates considerable heating, decreasing efficiency. The volume of power transmitted at confirmed temperature increases 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 sole threads yield larger ratios than multiple threads. All EP. worm equipment sets are available with either left or right hands threads. EP. worm equipment sets are offered with Qua, Sole, Double and Triple-druple Threads.
Basic safety PROVISION: Worm gearing should not be used as a locking mechanism to carry heavy weights where reversing action could cause harm or damage. In applications where potential damage is non-existent and self-locking is preferred against backward rotation in that case use of an individual thread worm with a minimal helix angle immediately locks the worm equipment get against backward rotation.
MATERIAL recommended for worms is certainly hardened steel and bronze for worm gears. However, depending on the application unhardened steel worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. In addition to metal and hardenedsteel, worms are available in bronze, nylon, metal and stainless; worm gears can be purchased in steel, hardened steel, stainless, light weight aluminum, nylon and nonmetallic (phenolic).
EP also sells equipment tooth measuring units called Equipment GAGES! Gear Gages lessen mistakes, save time and money when identifying and purchasing gears. These pitch templates can be found in nine sets to identify all the normal pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Fine Pitches, Coarse Pitches and Uncommon Pitches. Make reference to the section on GEAR GAGES for catalog figures when ordering.
