High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are exquisite for use in applications that demand high precise positioning, performance and repeatability. They were specifically developed for make use of with state-of-the-art servo electric motor technology, providing tight integration of the motor to the unit. Angular backlash of significantly less than 1 arc-mins is provided standard.
They are available in four sizes (50 mm to 100 mm center length) 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 electric motor couplings and mounting flanges are available for assembly to practically all servo motors, and the hollow bore productivity can be utilized to mount end result shafts, pinion shafts, or other drive elements.
Regular applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and digital line shafting. Industries offered include Material H, ling, Aerospace, Robotics, Machine Instrument and Automation.
Gearing: Internal gear design was optimized to supply an angular backlash of less than 1 arc-minutes in assembly, with the option of “in the discipline” adjustable backlash in the event that necessary.
Bearings: Input angular call bearings for high input speed, and robust outcome tapered-roller bearings for high radial and axial load capacity.
Housing: Light weight aluminum housing for good heat dissipation, with essential source flange for servo motors and general mounting on any deal with.
Output: The productivity bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension web pages). We provide a line of equipment 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 want extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-traveling the gearmotor so a position can be held even when power isn’t applied. The precision surface 3/8” stainless steel output shaft is reinforced by dual 3/8” ABEC 5 ball bearings to aid a load from any orientation. The ¼” ABS plastic and aluminum structure offers a rigid framework without adding pointless weight and is very easily installed to any flat work surface by utilizing the base mounting tabs. Our Regular Spur Gear motors will continue to work with this gearbox (motor purchased separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse devices and low-velocity applications that want high accuracy and torque.
Motor RPM required = 1 / (a few minutes per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor had a need to achieve 10 minutes per rotation (in max speed)
now offers an economical right angle gearhead for use with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers happen to be most appropriate for basic motion and insight speeds of 2000 rpm where profile software costs certainly are a major consideration.

Worm Gears are ideal angle drives providing huge speed ratios on comparatively brief center distances from 1/4” to 11”. When properly mounted and lubricated they function as quietist and smoothest running type of gearing. Due to the high ratios practical with worm gearing, maximal speed reduction could be accomplished in fewer space than many other types of gearing. Worm and worm gears operate on nonintersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a huge extent on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% more efficient than single thread worms. The mesh or engagement of worms with worm gears makes a sliding action triggering considerable friction and greater loss of efficiency beyond other styles of gearing. The utilization of hardened and floor worm swith bronze worm gears boosts efficiency.
LUBRICATION can be an essential factor to boost efficiency in worm gearing. Worm gear action generates considerable temperature, decreasing efficiency. The number of ability transmitted at a given temperature rises as the effectiveness of the gearing boosts. Proper lubrication enhances effectiveness by minimizing friction and heat.
RATIOS of worm equipment sets are dependant on dividing the quantity of teeth in the gear by the number of threads. Thus solitary threads yield higher ratios than multiple threads. All EP. worm gear sets are available with either still left or right hand threads. EP. worm equipment sets are offered with Triple, One, Qua and Double-druple Threads.
Security PROVISION: Worm gearing should not be used as a good locking mechanism to hold major weights where reversing actions can cause harm or harm. In applications where potential harm is nonexistent and self-locking is desired against backward rotation after that use of a single thread worm with a low helix angle automatically locks the worm equipment travel against backward rotation.
Materials recommended for worms is usually 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. In addition to steel and hardenedsteel, worms can be purchased in lightweight aluminum, bronze, nylon and stainless; worm gears can be found in steel, hardened metal, stainless, aluminum, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring gadgets called Equipment GAGES! Gear Gages decrease mistakes, save money and time when identifying and ordering gears. These pitch templates are available in nine sets to recognize all the common pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on Equipment GAGES for catalog quantities when ordering.
