High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are exquisite for use in applications that demand high performance, repeatability and precise positioning. They were particularly developed for employ with state-of-the-art servo engine technology, providing restricted integration of the motor to the unit. Angular backlash of less than 1 arc-moments is provided standard.
They can be purchased in four sizes (50 mm to 100 mm center distance) 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 variety of engine couplings and mounting flanges are available for assembly to practically all servo motors, and the hollow bore outcome can be utilised to mount outcome shafts, pinion shafts, or other drive elements.
Common 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, Aerospace, Automation, Robotics and Machine Tool.
Gearing: Internal gear design was optimized to provide an angular backlash of 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 result tapered-roller bearings for superior radial and axial load capacity.
Housing: Aluminium housing for good heat dissipation, with integral input flange for servo motors and common mounting on any encounter.
Output: The productivity bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension internet pages). 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-get reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not merely minimizes backlash but also eliminates back-driving the gearmotor so a posture can be placed even when power is not 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 light weight aluminum structure offers a rigid framework without adding needless weight and is quickly mounted to any flat surface by utilizing the base mounting tabs. Our Typical Spur Gear motors will work with this gearbox (motor marketed separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse devices and low-rate applications that want high precision and torque.
Motor RPM required = 1 / (minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve 10 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 best suited for basic movement and input speeds of 2000 rpm where profile program costs are a major consideration.

Worm Gears are best suited angle drives providing large acceleration ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as the quietist and smoothest working type of gearing. Due to high ratios practical 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 are powered by non-intersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a big level on the helix position of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% better than solitary thread worms. The mesh or engagement of worms with worm gears creates a sliding action leading to considerable friction and greater lack of efficiency beyond other styles of gearing. The use of hardened and surface worm swith bronze worm gears rises efficiency.
LUBRICATION is an essential factor to boost efficiency found in worm gearing. Worm equipment action generates considerable temperature, decreasing efficiency. The number of vitality transmitted at a given temperature raises as the proficiency of the gearing raises. Proper lubrication enhances proficiency by reducing friction and heat.
RATIOS of worm equipment sets are determined by dividing the quantity of teeth in the apparatus by the amount of threads. Thus single threads yield bigger ratios than multiple threads. All EP. worm gear sets can be found with either left or right hand threads. EP. worm gear sets are offered with Single, Qua, Triple and Double-druple Threads.
Safeness PROVISION: Worm gearing shouldn’t be used as a good locking mechanism to carry major weights where reversing action could cause harm or harm. In applications where potential harm is nonexistent and self-locking is wanted against backward rotation in that case use of a single thread worm with a minimal helix angle instantly locks the worm gear drive against backward rotation.
Materials recommended for worms is usually hardened steel and bronze for worm gears. However, depending on the application form unhardened steel worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms can be purchased in light weight aluminum, stainless, nylon and bronze; worm gears can be found in steel, hardened steel, stainless, lightweight aluminum, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring gadgets called GEAR GAGES! Gear Gages lessen mistakes, save time and money when identifying and buying gears. These pitch templates can be found in nine sets to recognize all the regular pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Uncommon Pitches. Make reference to the section on GEAR GAGES for catalog numbers when ordering.
