EP offers a full range of modular servo gearboxes /worm reducers. The modular design allows for configurations with motor source flange and result pinion for rack and pinion drives, in addition to solid productivity shafts, Hollow bore result, and insight shafts for all other positioning applications. The modular style allows for general mounting of the gearbox in virtually any orientation.
Servo-Worm Reducers were especially developed for work with with the most recent servo motors in applications that demand exact positioning and repeatability.
These reducers are suitable for applications in material handling, automation, machine tool, and robotics.

High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are perfect for use in applications that demand high performance, repeatability and precise positioning. They were especially developed for make use of with state-of-the-art servo engine technology, providing limited integration of the engine to the machine. Angular backlash of less than 1 arc-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 electric motor couplings and mounting flanges are for sale to assembly to nearly all servo motors, and the hollow bore outcome can be used to mount output shafts, pinion shafts, or other drive elements.
Common applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives, zero-backlash axis drives and digital line shafting. Industries dished up include Material H, ling, Machine Device, Automation, Aerospace and Robotics.
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 if necessary.
Bearings: Input angular get in touch with bearings for high suggestions speed, and robust end result tapered-roller bearings for great radial and axial load potential.
Housing: Light weight aluminum housing for good heat dissipation, with integral type flange for servo motors and universal mounting on any deal with.
Output: The end result bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension webpages). 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 also eliminates back-generating the gearmotor so a position can be held even when power isn’t applied. The precision ground 3/8” stainless steel output shaft is backed 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 unnecessary weight and is quickly installed to any flat surface by utilizing the base mounting tabs. Our Common Spur Gear motors will work with this gearbox (motor offered separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse systems and low-velocity applications that want high precision and torque.
Motor RPM required = 1 / (mins 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 offers an economical right position gearhead for make use of with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers are most appropriate for basic motion and suggestions speeds of 2000 rpm where profile software costs certainly are a major consideration.

Worm Gears are right angle drives providing large quickness ratios on comparatively short center distances from 1/4” to 11”. When properly installed 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 can 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 big level on the helix position 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 produces a sliding action creating considerable friction and greater loss of efficiency beyond other styles of gearing. The use of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to boost efficiency found in worm gearing. Worm equipment action generates considerable temperature, decreasing efficiency. How much ability transmitted at a given temperature boosts as the efficiency of the gearing increases. Proper lubrication enhances efficiency by reducing friction and heat.
RATIOS of worm gear sets are dependant on dividing the number of teeth in the gear by the number of threads. Thus one threads yield larger ratios than multiple threads. All EP. worm equipment sets are available with either still left or right side threads. EP. worm gear sets are offered with Qua, Double, Triple and Single-druple Threads.
Protection PROVISION: Worm gearing should not be used as a locking mechanism to carry major weights where reversing action could cause harm or personal injury. In applications where potential harm is non-existent and self-locking is preferred against backward rotation in that case use of an individual thread worm with a low helix angle quickly locks the worm gear drive against backward rotation.
Materials recommended for worms is definitely hardened steel and bronze for worm gears. Even so, depending on the application form unhardened metal worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms can be purchased in bronze, stainless, nylon and aluminum; worm gears are available in steel, hardened steel, stainless, light weight aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring devices called GEAR GAGES! Gear Gages reduce mistakes, save time and money when identifying and purchasing gears. These pitch templates can be purchased in nine sets to recognize all the common pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Great Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on GEAR GAGES for catalog numbers when ordering.
