High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are exquisite for use in applications that demand high performance, precise positioning and repeatability. They were particularly developed for use with state-of-the-art servo electric motor technology, providing restricted integration of the motor to the unit. 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 distance) 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 wide variety of electric motor couplings and mounting flanges are for sale to assembly to almost all servo motors, and the hollow bore productivity can be used to mount result shafts, pinion shafts, or other drive elements.
Typical applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and electronic digital line shafting. Industries dished up include Material H, Automation, ling, Aerospace, Machine Tool and Robotics.
Gearing: Internal gear style was optimized to supply 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 contact bearings for high source speed, and robust result tapered-roller bearings for superior radial and axial load capability.
Housing: Aluminium housing for good heat dissipation, with essential source flange for servo motors and general mounting on any face.
Output: The outcome bore is available with a compression-type hub or a good ISO 9409-1 flange (see dimension pages). We offer a line of accessories 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 only minimizes backlash but also eliminates back-generating the gearmotor so a posture can be held even when power is not applied. The precision surface 3/8” stainless steel output shaft is backed by dual 3/8” ABEC 5 ball bearings to aid a load from any orientation. The ¼” ABS plastic and metal structure offers a rigid framework without adding pointless weight and is conveniently attached to any flat work surface by utilizing the bottom mounting tabs. Our Typical Spur Gear motors will work with this gearbox (electric motor distributed separately). The Vertical Shaft 
Worm-Drive Gearbox is perfect for turn-tables, time-lapse devices and low-quickness applications that want high precision 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 ten minutes per rotation (in max speed)
now offers an economical right position gearhead for work with with small NEMA 23 through 56 and similar small metric servo and stepper motors. These reducers are best suited for basic action and type speeds of 2000 rpm where profile program costs are a major consideration.

Worm Gears are best angle drives providing large acceleration ratios on comparatively short center distances from 1/4” to 11”. When correctly attached and lubricated they function as quietist and smoothest working type of gearing. Due to the high ratios possible 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 equipment drives depends to a large level on the helix angle of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% more efficient than single thread worms. The mesh or engagement of worms with worm gears creates a sliding action causing considerable friction and better loss 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 warmth, decreasing efficiency. The amount of ability transmitted at a given temperature boosts as the proficiency of the gearing increases. Proper lubrication enhances proficiency by reducing friction and heat.
RATIOS of worm equipment sets are determined by dividing the amount of teeth in the gear by the number of threads. Thus single threads yield larger ratios than multiple threads. All EP. worm gear sets can be found with either left or right palm threads. EP. worm equipment sets can be found with Qua, Triple, Double and Single-druple Threads.
Basic safety PROVISION: Worm gearing should not be used as a good locking mechanism to hold heavy weights where reversing action could cause harm or injury. In applications where potential harm is non-existent and self-locking is preferred against backward rotation after that use of a single thread worm with a minimal helix angle automatically locks the worm gear get against backward rotation.
MATERIAL recommended for worms is definitely hardened steel and bronze for worm gears. Even so, depending on the application unhardened steel worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms can be found in nylon, lightweight aluminum, stainless and bronze; worm gears are available in steel, hardened metal, stainless, metal, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring equipment called GEAR GAGES! Gear Gages lessen mistakes, save time and money when identifying and purchasing gears. These pitch templates can be found in nine sets to recognize all the typical pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Excellent Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on GEAR GAGES for catalog amounts when ordering.
