High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are exquisite for use in applications that demand high performance, precise positioning and repeatability. They were particularly developed for employ with state-of-the-art servo engine technology, providing limited integration of the motor to the machine. Angular backlash of significantly less than 1 arc-minutes is provided standard.
They can be purchased 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 almost all servo motors, and the hollow bore productivity can be utilised to mount output shafts, pinion shafts, or other drive elements.
Normal applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives, zero-backlash axis drives and electronic digital line shafting. Industries served include Material H, Automation, ling, Aerospace, Machine Software and Robotics.
Gearing: Internal gear design was optimized to supply an angular backlash of significantly less than 1 arc-minutes in assembly, with the choice of “in the discipline” adjustable backlash in the event that necessary.
Bearings: Input angular call bearings for high input speed, and robust outcome tapered-roller bearings for superior radial and axial load ability.
Housing: Light weight aluminum housing once and for all heat dissipation, with integral suggestions flange for servo motors and general mounting on any encounter.
Output: The outcome bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension pages). We give a line of gadgets 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 merely minimizes backlash but also eliminates back-traveling the gearmotor so a position can be kept even when power isn’t applied. The precision surface 3/8” stainless steel result shaft is supported by dual 3/8” ABEC 5 ball bearings to support lots from any orientation. The ¼” ABS plastic and light weight aluminum structure provides a rigid framework without adding unneeded weight and is conveniently mounted to any flat work surface by utilizing the base mounting tabs. Our Regular 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-swiftness applications that want high accuracy and torque.
Motor RPM required = 1 / (moments per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor had a need to achieve ten minutes per rotation (in max speed)
now offers an economical right position gearhead for make use of with small NEMA 23 through 56 and similar little metric servo and stepper motors. These reducers will be most appropriate for basic action and source speeds of 2000 rpm where profile software costs certainly are a major consideration.

Worm Gears are ideal angle drives providing huge quickness ratios on comparatively short center distances from 1/4” to 11”. When correctly installed and lubricated they function as quietist and smoothest jogging type of gearing. Due to high ratios likely with worm gearing, optimum speed reduction can be accomplished in much 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 angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than solo thread worms. The mesh or engagement of worms with worm gears produces a sliding action creating considerable friction and increased lack of efficiency beyond other types of gearing. The utilization of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to boost efficiency found in worm gearing. Worm equipment action generates considerable heat, decreasing efficiency. The quantity of ability transmitted at a given temperature raises as the performance of the gearing raises. Proper lubrication enhances efficiency by minimizing friction and heat.
RATIOS of worm equipment sets are dependant on dividing the amount of teeth in the apparatus by the amount of threads. Thus solitary threads yield bigger ratios than multiple threads. All EP. worm gear sets can be found with either left or right palm threads. EP. worm gear sets are offered with One, Triple, Double and Qua-druple Threads.
Safe practices PROVISION: Worm gearing should not be used as a good locking mechanism to carry heavy weights where reversing actions can cause harm or damage. In applications where potential damage is non-existent and self-locking is preferred against backward rotation then use of a single thread worm with a low helix angle quickly locks the worm gear drive against backward rotation.
Materials recommended for worms is definitely hardened steel and bronze for worm gears. Nevertheless, depending on the application unhardened metal worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms can be found in bronze, nylon, lightweight aluminum and stainless; worm gears can be purchased in steel, hardened steel, stainless, light weight aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring gadgets called GEAR GAGES! Gear Gages lessen mistakes, save money and time when identifying and ordering gears. These pitch templates can be purchased in nine sets to identify all the common pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Uncommon Pitches. Refer to the section on Equipment GAGES for catalog numbers when ordering.
