High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are simply perfect for use in applications that demand high repeatability, performance and precise positioning. They were especially developed for use with state-of-the-art servo engine technology, providing limited integration of the electric motor to the machine. Angular backlash of less than 1 arc-moments is provided standard.
They are available 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 wide selection of electric motor couplings and mounting flanges are available for assembly to virtually all servo motors, and the hollow bore output works extremely well to mount end result shafts, pinion shafts, or other drive elements.
Normal 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, Aerospace, Machine Application and Automation.
Gearing: Internal gear design was optimized to provide an angular backlash of significantly less than 1 arc-minutes at assembly, with the option of “in the discipline” adjustable backlash if necessary.
Bearings: Input angular call bearings for high insight speed, and robust outcome tapered-roller bearings for superior radial and axial load ability.
Housing: Aluminium housing for good heat dissipation, with essential type flange for servo motors and universal mounting on any deal with.
Output: The output bore is available with a compression-type hub or a ISO 9409-1 flange (see dimension webpages). We give you a line of gadgets to adapt these outputs to straight shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but as well eliminates back-driving the gearmotor so a posture can be held even when power is not applied. The precision floor 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 metal structure offers a rigid framework without adding needless weight and is quickly installed to any flat surface by utilizing the bottom mounting tabs. Our Common Spur Gear motors will continue to work with this gearbox (electric motor purchased separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse systems and low-swiftness 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 angle gearhead for work with with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers happen to be most appropriate for basic action and insight speeds of 2000 rpm where profile program costs certainly are a major consideration.

Worm Gears are best suited angle drives providing huge swiftness ratios on comparatively brief center distances from 1/4” to 11”. When correctly mounted and lubricated they function as the quietist and smoothest running type of gearing. Because of the high ratios feasible with worm gearing, maximal speed reduction could be accomplished in fewer space than a great many other types of gearing. Worm and worm gears are powered by nonintersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a large extent on the helix angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than sole thread worms. The mesh or engagement of worms with worm gears generates a sliding action causing considerable friction and greater loss of efficiency beyond other types of gearing. The use of hardened and floor worm swith bronze worm gears boosts efficiency.
LUBRICATION can be an essential factor to improve efficiency in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. How much ability transmitted at a given temperature rises as the efficiency of the gearing rises. Proper lubrication enhances efficiency by minimizing friction and heat.
RATIOS of worm gear sets are determined by dividing the number of teeth in the gear by the number 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 palm threads. EP. worm gear sets are offered with Double, Triple, Solitary and Qua-druple Threads.
SAFETY PROVISION: Worm gearing should not be used as a locking mechanism to carry heavy weights where reversing action can cause harm or damage. In applications where potential damage is non-existent and self-locking is wanted against backward rotation then use of a single thread worm with a minimal helix angle instantly locks the worm gear get against backward rotation.
MATERIAL recommended for worms is definitely hardened steel and bronze for worm gears. On the other hand, depending on the application form unhardened steel worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. In addition to steel and hardenedsteel, worms can be found in light weight aluminum, nylon, stainless and bronze; worm gears are available in steel, hardened steel, stainless, lightweight aluminum, nylon and nonmetallic (phenolic).
EP also sells equipment tooth measuring devices called GEAR GAGES! Gear Gages decrease mistakes, save money and time when identifying and buying gears. These pitch templates can be found in nine sets to recognize all the standard pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External 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.
