High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are perfect for use in applications that demand high performance, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo electric motor technology, providing restricted integration of the electric motor to the unit. Angular backlash of less than 1 arc-mins is provided standard.
They are available 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 range of engine couplings and mounting flanges are available for assembly to almost all servo motors, and the hollow bore result can be used to mount output shafts, pinion shafts, or other drive elements.
Standard applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives, zero-backlash axis drives and electronic line shafting. Industries served include Material H, ling, Automation, Aerospace, Robotics and Machine Tool.
Gearing: Internal gear style was optimized to supply an angular backlash of significantly less than 1 arc-minutes in assembly, with the option of “in the discipline” adjustable backlash in the event necessary.
Bearings: Input angular call bearings for high input speed, and robust productivity tapered-roller bearings for great radial and axial load potential.
Housing: Light weight aluminum housing once and for all heat dissipation, with essential source flange for servo motors and common mounting on any face.
Output: The end result bore is available with a compression-type hub or a ISO 9409-1 flange (see dimension web pages). We offer a line of accessories to adapt these outputs to direct 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-traveling the gearmotor so a position can be placed even when power is not applied. The precision surface 3/8” stainless steel outcome shaft is supported by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and aluminium structure provides a rigid framework without adding needless weight and is conveniently mounted to any flat work surface by utilizing the base mounting tabs. Our Typical Spur Gear motors will continue to work with this gearbox (electric motor purchased separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-rate applications that require high precision and torque.
Motor RPM required = 1 / (mins per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (in max speed)
now provides an economical right angle gearhead for employ with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers happen to be best suited for basic action and insight speeds of 2000 rpm where profile program costs certainly are a major consideration.

Worm Gears are best angle drives providing large rate ratios on comparatively short center distances from 1/4” to 11”. When effectively installed and lubricated they function as quietist and smoothest running type of gearing. As a result of high ratios conceivable with worm gearing, maximal speed reduction could be accomplished in much less space than a great 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 sizable extent on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better than solitary thread worms. The mesh or engagement of worms with worm gears creates a sliding action causing considerable friction and better lack of efficiency beyond other styles of gearing. The use of hardened and surface worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to improve efficiency in worm gearing. Worm gear action generates considerable warmth, decreasing efficiency. How much vitality transmitted at a given temperature increases as the effectiveness of the gearing boosts. Proper lubrication enhances productivity by reducing friction and heat.
RATIOS of worm gear sets are dependant on dividing the quantity of teeth in the gear by the number of threads. Thus solitary threads yield bigger ratios than multiple threads. All EP. worm equipment sets can be found with either still left or right side threads. EP. worm equipment sets can be found with Double, Solo, Qua and Triple-druple Threads.
SAFETY PROVISION: Worm gearing should not be used as a good locking mechanism to carry large weights where reversing actions can cause harm or damage. In applications where potential damage is non-existent and self-locking is preferred against backward rotation then use of an individual thread worm with a minimal helix angle automatically locks the worm equipment get against backward rotation.
Materials recommended for worms is 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 steel and hardenedsteel, worms can be found in bronze, aluminium, stainless and nylon; worm gears are available in steel, hardened metal, stainless, lightweight aluminum, nylon and nonmetallic (phenolic).
EP also sells gear tooth measuring devices called Equipment GAGES! Gear Gages reduce mistakes, save time and money when identifying and ordering gears. These pitch templates are available in nine sets to identify all the standard pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Good Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on GEAR GAGES for catalog numbers when ordering.
