High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are ideal for use in applications that demand high precise positioning, performance and repeatability. They were especially developed for work with with state-of-the-art servo engine technology, providing restricted integration of the motor to the unit. Angular backlash of less than 1 arc-mins is provided standard.
They can be purchased in four sizes (50 mm to 100 mm center range) 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 selection of motor couplings and mounting flanges are available for assembly to almost 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 electric line shafting. Industries offered include Material H, ling, Machine Application, Robotics, Aerospace and Automation.
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 contact bearings for high source speed, and robust output tapered-roller bearings for high radial and axial load capacity.
Housing: Light weight aluminum housing once and for all heat dissipation, with essential input flange for servo motors and universal mounting on any face.
Output: The outcome bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension webpages). We give a line of accessories to adapt these outputs to right shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-travel reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but as well eliminates back-generating the gearmotor so a posture can be kept even when power isn’t applied. The precision floor 3/8” stainless steel result shaft is reinforced by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and metal structure offers a rigid framework without adding needless weight and is easily attached to any flat surface by utilizing the base mounting tabs. Our Typical Spur Gear motors will continue to work with this gearbox (motor purchased separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse systems and low-velocity applications that want high accuracy and torque.
Motor RPM required = 1 / (mins 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 provides an economical right position gearhead for work with with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers happen to 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 significant swiftness ratios on comparatively brief center distances from 1/4” to 11”. When correctly attached and lubricated they function as quietist and smoothest running type of gearing. Because of the high ratios feasible with worm gearing, maximum speed reduction could be accomplished in fewer space than a great many other types of gearing. Worm and worm gears operate on non-intersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a big extent on the helix angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than solo thread worms. The mesh or engagement of worms with worm gears produces a sliding action triggering considerable friction and better loss of efficiency beyond other styles of gearing. The usage of hardened and ground worm swith bronze worm gears rises efficiency.
LUBRICATION is an essential factor to boost efficiency found in worm gearing. Worm gear action generates considerable heating, decreasing efficiency. The quantity of power transmitted at a given temperature raises as the proficiency of the gearing increases. Proper lubrication enhances productivity by minimizing friction and heat.
RATIOS of worm gear sets are dependant on dividing the number of teeth in the gear by the amount of threads. Thus one threads yield bigger ratios than multiple threads. All EP. worm gear sets are available with either still left or right palm threads. EP. worm gear sets can be found with Double, Qua, Triple and Single-druple Threads.
Protection PROVISION: Worm gearing shouldn’t be used as a locking mechanism to hold major weights where reversing action can cause harm or harm. In applications where potential damage is non-existent and self-locking is wanted against backward rotation after that use of a single thread worm with a minimal helix angle automatically locks the worm gear travel against backward rotation.
Materials recommended for worms is going to be hardened steel and bronze for worm gears. On the other hand, depending on the application form unhardened steel worms operate adequately and extra economically with cast iron worm gears at 50% horsepower ratings. In addition to metal and hardenedsteel, worms are available in nylon, bronze, stainless and aluminum; worm gears can be purchased in steel, hardened metal, stainless, lightweight aluminum, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring devices called Equipment GAGES! Gear Gages decrease mistakes, save money and time when identifying and purchasing gears. These pitch templates can be found in nine sets to identify all the common pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on Equipment GAGES for catalog amounts when ordering.
