High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are exquisite for use in applications that demand high precise positioning, repeatability and performance. They were specifically developed for use with state-of-the-art servo electric motor technology, providing restricted integration of the motor to the unit. 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 length) 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 engine couplings and mounting flanges are for sale to assembly to nearly all servo motors, and the hollow bore output works extremely well 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 electric line shafting. Industries offered include Material H, ling, Robotics, Automation, Machine Application and Aerospace.
Gearing: Internal gear style was optimized to provide an angular backlash of significantly less than 1 arc-minutes in assembly, with the choice of “in the discipline” adjustable backlash in the event necessary.
Bearings: Input angular get in touch with bearings for high input speed, and robust result tapered-roller bearings for large radial and axial load capability.
Housing: Aluminium housing once and for all heat dissipation, with essential insight flange for servo motors and universal mounting on any encounter.
Output: The productivity bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension webpages). We offer a line of add-ons to adjust these outputs to direct 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 also eliminates back-generating the gearmotor so a position can be placed even when power isn’t applied. The precision surface 3/8” stainless steel result shaft is reinforced by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and aluminum structure provides a rigid framework without adding pointless weight and is very easily attached to any flat work surface by utilizing the base mounting tabs. Our Standard Spur Gear motors will continue to work with this gearbox (motor sold separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse systems and low-rate applications that require high precision and torque.
Motor RPM required = 1 / (a few minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve ten minutes per rotation (in max speed)
now offers an economical right position gearhead for use with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers happen to be most appropriate for basic motion and input speeds of 2000 rpm where profile request costs are a major consideration.

Worm Gears are ideal angle drives providing large quickness ratios on comparatively short center distances from 1/4” to 11”. When effectively attached and lubricated they function as quietist and smoothest operating type of gearing. Due to 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 are powered by non-intersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a huge extent on the helix angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than single thread worms. The mesh or engagement of worms with worm gears generates a sliding action causing considerable friction and increased loss of efficiency beyond other styles of gearing. The make use of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to improve efficiency in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The quantity of electric power transmitted at confirmed temperature boosts as the proficiency of the gearing raises. Proper lubrication enhances proficiency by lowering friction and heat.
RATIOS of worm equipment sets are dependant on dividing the number of teeth in the gear by the amount of threads. Thus sole threads yield bigger ratios than multiple threads. All EP. worm gear sets are available with either still left or right side threads. EP. worm gear sets can be found with Triple, Double, Qua and Single-druple Threads.
Basic safety PROVISION: Worm gearing should not be used as a locking mechanism to hold major weights where reversing actions could cause harm or harm. In applications where potential damage is nonexistent and self-locking is wanted against backward rotation in that case use of a single thread worm with a minimal helix angle automatically locks the worm gear get against backward rotation.
Materials recommended for worms is hardened steel and bronze for worm gears. On the other hand, depending on the application unhardened metal worms operate adequately and more economically with cast iron worm gears at 50% horsepower ratings. In addition to metal and hardenedsteel, worms can be found in stainless, light weight aluminum, nylon and bronze; worm gears are available in steel, hardened metal, stainless, metal, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring devices called Equipment GAGES! Gear Gages lessen mistakes, save money and time when identifying and buying 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 Uncommon Pitches. Make reference to the section on Equipment GAGES for catalog amounts when ordering.
