High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are ideal for use in applications that demand high precise positioning, repeatability and performance. They were particularly developed for use with state-of-the-art servo engine technology, providing restricted integration of the electric motor to the unit. Angular backlash of significantly less than 1 arc-a few minutes is provided standard.
They are available in four sizes (50 mm to 100 mm center length) with input speeds up 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 motor couplings and mounting flanges are for sale to assembly to virtually all servo motors, and the hollow bore end result can be utilized to mount outcome shafts, pinion shafts, or other drive elements.
Common applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and digital line shafting. Industries offered include Material H, ling, Machine Device, Aerospace, Robotics and Automation.
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 field” adjustable backlash in the event that necessary.
Bearings: Input angular get in touch with bearings for high suggestions speed, and robust result tapered-roller bearings for superior radial and axial load capability.
Housing: Aluminium housing once and for all heat dissipation, with essential insight flange for servo motors and general mounting on any encounter.
Output: The result bore is available with a good compression-type hub or a good ISO 9409-1 flange (see dimension web pages). We give you a line of add-ons to adapt 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 merely minimizes backlash but also eliminates back-generating the gearmotor so a position can be kept even when power isn’t applied. The precision floor 3/8” stainless steel end result shaft is backed by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and aluminum structure offers a rigid framework without adding pointless weight and is easily mounted to any flat surface by utilizing the bottom mounting tabs. Our Common Spur Gear motors will continue to work with this gearbox (motor offered separately). The Vertical Shaft Worm-Drive Gearbox is exquisite for turn-tables, time-lapse systems and low-quickness 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 needed to achieve 10 minutes per rotation (in max speed)
now provides an economical right position gearhead for employ with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers will be most appropriate for basic movement and input speeds of 2000 rpm where profile program costs are a major consideration.

Worm Gears are ideal angle drives providing huge speed ratios on comparatively brief center distances from 1/4” to 11”. When effectively attached and lubricated they function as the quietist and smoothest jogging type of gearing. Due to the high ratios practical with worm gearing, maximum speed reduction can be accomplished in less 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 big degree on the helix position 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 makes a sliding action causing considerable friction and better loss of efficiency beyond other types of gearing. The make use of hardened and ground worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to improve efficiency found in worm gearing. Worm equipment action generates considerable heating, decreasing efficiency. The number of ability 
transmitted at confirmed temperature rises as the efficiency of the gearing increases. Proper lubrication enhances proficiency by minimizing friction and heat.
RATIOS of worm equipment sets are dependant on dividing the number of teeth in the apparatus by the amount of threads. Thus solitary threads yield bigger ratios than multiple threads. All EP. worm gear sets are available with either left or right side threads. EP. worm gear sets can be found with Triple, Single, Qua and Double-druple Threads.
Basic safety PROVISION: Worm gearing should not be used as a locking mechanism to carry major weights where reversing action could cause harm or damage. In applications where potential damage is non-existent and self-locking is wanted against backward rotation after that use of an individual thread worm with a low helix angle immediately locks the worm equipment get against backward rotation.
Materials recommended for worms is usually hardened steel and bronze for worm gears. Nevertheless, depending on the application unhardened steel worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms are available in nylon, aluminium, bronze and stainless; worm gears are available in steel, hardened steel, stainless, metal, nylon and nonmetallic (phenolic).
EP also sells gear tooth measuring equipment called Equipment GAGES! Gear Gages decrease mistakes, save money and time when identifying and purchasing gears. These pitch templates can be purchased in nine sets to identify all the normal pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, External Involute Splines, Metric Module “MOD”, Stub Tooth, Good Pitches, Coarse Pitches and Unusual Pitches. Make reference to the section on GEAR GAGES for catalog quantities when ordering.
