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 make use of with state-of-the-art servo engine technology, providing restricted integration of the electric motor to the machine. Angular backlash of significantly less than 1 arc-a few minutes 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 range of motor couplings and mounting flanges are available for assembly to practically all servo motors, and the hollow bore end result can be utilised to mount result 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 electric line shafting. Industries offered include Material H, ling, Robotics, Aerospace, Machine Software and Automation.
Gearing: Internal gear design was optimized to supply an angular backlash of less than 1 arc-minutes at assembly, with the choice of “in the discipline” adjustable backlash if necessary.
Bearings: Input angular call bearings for high source speed, and robust output tapered-roller bearings for large radial and axial load potential.
Housing: Light weight aluminum housing once and for all heat dissipation, with essential input flange for servo motors and common mounting on any encounter.
Output: The productivity bore is available with a good compression-type hub or a good ISO 9409-1 flange (see dimension web pages). We give 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-get reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but likewise eliminates back-driving the gearmotor so a posture can be kept even when power is not applied. The precision floor 3/8” stainless steel productivity shaft is supported 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 pointless weight and is very easily installed to any flat surface by utilizing the base mounting tabs. Our Common Spur Gear motors will continue to work with this gearbox (engine sold separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse systems and low-velocity applications that require 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 ten minutes per rotation (in max speed)
now offers an economical right angle gearhead for make use of with small NEMA 23 through 56 and similar small metric servo and stepper motors. These reducers will be best suited for basic action and suggestions speeds of 2000 rpm where profile application costs are a major consideration.

Worm Gears are best angle drives providing huge acceleration ratios on comparatively brief center distances from 1/4” to 11”. When properly installed and lubricated they function as quietist and smoothest working type of gearing. Due to high ratios feasible with worm gearing, maximum 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 sizable degree on the helix angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% more efficient than one thread worms. The mesh or engagement of worms with worm gears produces a sliding action causing considerable friction and higher lack of efficiency beyond other types of gearing. The use of hardened and floor worm swith bronze worm gears raises efficiency.
LUBRICATION is an essential factor to improve efficiency found in worm gearing. Worm gear action generates considerable heating, decreasing efficiency. The volume of electricity transmitted at a given temperature boosts as the performance of the gearing raises. Proper lubrication enhances performance by lowering friction and heat.
RATIOS of worm gear sets are determined by dividing the number of teeth in the gear by the amount of threads. Thus solo threads yield higher ratios than multiple threads. All EP. worm equipment sets can be found with either still left or right hand threads. EP. worm gear sets can be found with Triple, Double, Solo and Qua-druple Threads.
Security PROVISION: Worm gearing shouldn’t be used as a locking mechanism to carry major weights where reversing action can cause harm or injury. In applications where potential injury is nonexistent and self-locking is preferred against backward rotation after that use of an individual thread worm with a low helix angle instantly locks the worm gear drive against backward rotation.
Materials recommended for worms is usually hardened steel and bronze for worm gears. On the other hand, depending on the application form unhardened metal worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. In addition to metal and hardenedsteel, worms are available in stainless, lightweight aluminum, nylon and bronze; worm gears can be found in steel, hardened steel, stainless, metal, nylon and nonmetallic (phenolic).
EP also sells equipment tooth measuring gadgets called Equipment GAGES! Gear Gages lessen mistakes, save time and money when identifying and buying gears. These pitch templates are available in nine sets to identify all the regular pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Great Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on GEAR GAGES for catalog figures when ordering.
