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 specifically developed for employ with state-of-the-art servo engine technology, providing tight integration of the electric motor to the machine. Angular backlash of 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 speeds up to 5,000 rpm, reduction ratios from 4.75 to 52:1 and output torque capacities up to 885 lb.ft. A wide selection of motor couplings and mounting flanges are for sale to assembly to almost all servo motors, and the hollow bore output can be utilized to mount end result shafts, pinion shafts, or other drive elements.
Usual 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, Machine Application and Aerospace.
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 contact bearings for high insight speed, and robust result tapered-roller bearings for superior radial and axial load potential.
Housing: Light weight aluminum housing once and for all heat dissipation, with essential source flange for servo motors and universal mounting on any face.
Output: The result bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension internet pages). We give a line of components to adapt these outputs to straight shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-travel reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but likewise eliminates back-traveling the gearmotor so a position can be held even when power isn’t applied. The precision surface 3/8” stainless steel result shaft is backed by dual 3/8” ABEC 5 ball bearings to aid a load from any orientation. The ¼” ABS plastic and lightweight aluminum structure provides a rigid framework without adding needless weight and is easily installed to any flat surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will continue to work with this gearbox (motor distributed separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse devices and low-acceleration applications that want high accuracy 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 ten minutes per rotation (in max speed)
now offers an economical right angle gearhead for employ with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers will be most appropriate for basic action and source speeds of 2000 rpm where profile request costs are a major consideration.

Worm Gears are ideal angle drives providing huge speed ratios on comparatively short center distances from 1/4” to 11”. When correctly attached and lubricated they function as the quietist and smoothest working type of gearing. Due to high ratios likely with worm gearing, maximum speed reduction can be accomplished in much less space than many other types of gearing. Worm and worm gears operate on non-intersecting shafts at 90° angles.
EFFICIENCY of worm equipment drives depends to a huge level on the helix position of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% better than solo thread worms. The mesh or engagement of worms with worm gears produces a sliding action leading to considerable friction and higher lack of efficiency beyond other styles of gearing. The use of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to improve efficiency found in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The quantity of power transmitted at confirmed temperature boosts as the productivity of the gearing boosts. Proper lubrication enhances productivity by minimizing friction and 
heat.
RATIOS of worm gear sets are determined by dividing the number of teeth in the apparatus by the number 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 palm threads. EP. worm gear sets can be found with Triple, Qua, Single and Double-druple Threads.
Protection PROVISION: Worm gearing should not be used as a good locking mechanism to carry large weights where reversing actions could cause harm or harm. In applications where potential harm is nonexistent and self-locking is desired against backward rotation then use of a single thread worm with a low helix angle instantly locks the worm equipment drive against backward rotation.
MATERIAL recommended for worms is definitely hardened steel and bronze for worm gears. On the other hand, depending on the application unhardened steel worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms can be found in nylon, metal, bronze and stainless; worm gears can be found in steel, hardened steel, stainless, aluminum, nylon and nonmetallic (phenolic).
EP also sells equipment tooth measuring products called Equipment GAGES! Gear Gages lessen 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”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Fine Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on Equipment GAGES for catalog amounts when ordering.
