High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are ideal for use in applications that demand high precise positioning, repeatability and performance. They were especially developed for use with state-of-the-art servo engine technology, providing restricted integration of the engine to the unit. Angular backlash of significantly less than 1 arc-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 wide selection of engine couplings and mounting flanges are available for assembly to nearly all servo motors, and the hollow bore end result works extremely well to mount end result shafts, pinion shafts, or other 
drive elements.
Usual 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 dished up include Material H, ling, Aerospace, Machine Software, Automation and Robotics.
Gearing: Internal gear design was optimized to provide an angular backlash of significantly less than 1 arc-minutes in assembly, with the option of “in the discipline” adjustable backlash in the event that necessary.
Bearings: Input angular call bearings for high source speed, and robust output tapered-roller bearings for superior radial and axial load capability.
Housing: Aluminium housing for good heat dissipation, with integral source flange for servo motors and general mounting on any face.
Output: The productivity bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension pages). We give a line of accessories to adjust these outputs to right shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-drive reduction for applications that require extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but as well eliminates back-traveling the gearmotor so a posture can be kept even when power isn’t applied. The precision ground 3/8” stainless steel outcome shaft is reinforced by dual 3/8” ABEC 5 ball bearings to aid a load from any orientation. The ¼” ABS plastic and metal structure provides a rigid framework without adding unnecessary weight and is easily installed to any flat surface by utilizing the bottom mounting tabs. Our Typical Spur Gear motors will work with this gearbox (motor offered separately). The Vertical Shaft Worm-Drive Gearbox is ideal for turn-tables, time-lapse devices and low-swiftness applications that require high precision and torque.
Motor RPM required = 1 / (minutes per rotation desired / 30)
Example: 1 / (10 minutes per rotation / 30) = 3 RPM motor had a need to achieve ten minutes per rotation (at max speed)
now offers an economical right angle gearhead for use with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers are best suited for basic action and input speeds of 2000 rpm where profile software costs certainly are a major consideration.

Worm Gears are ideal angle drives providing significant speed ratios on comparatively short center distances from 1/4” to 11”. When properly mounted and lubricated they function as quietist and smoothest operating type of gearing. Because of the high ratios conceivable with worm gearing, optimum speed reduction could be accomplished in fewer space than a great many other types of gearing. Worm and worm gears are powered by non-intersecting shafts at 90° angles.
EFFICIENCY of worm gear drives depends to a huge degree on the helix position of the worm. Multiple thread worms and gears with higher helix angle prove 25% to 50% better than one thread worms. The mesh or engagement of worms with worm gears creates a sliding action leading to considerable friction and higher lack of efficiency beyond other types of gearing. The make use of hardened and floor worm swith bronze worm gears raises efficiency.
LUBRICATION is an essential factor to improve efficiency in worm gearing. Worm gear action generates considerable heating, decreasing efficiency. The amount of ability transmitted at a given temperature rises as the effectiveness of the gearing raises. Proper lubrication enhances effectiveness by reducing friction and heat.
RATIOS of worm equipment sets are determined by dividing the quantity of teeth in the apparatus by the number of threads. Thus solitary threads yield larger ratios than multiple threads. All EP. worm gear sets are available with either still left or right palm threads. EP. worm gear sets are offered with Triple, Qua, Double and Single-druple Threads.
Protection PROVISION: Worm gearing shouldn’t be used as a good locking mechanism to carry heavy weights where reversing action can cause harm or harm. In applications where potential injury is non-existent and self-locking is desired against backward rotation then use of an individual thread worm with a low helix angle instantly locks the worm equipment drive against backward rotation.
MATERIAL recommended for worms is going to be hardened steel and bronze for worm gears. Nevertheless, depending on the application form unhardened metal worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms are available in stainless, nylon, bronze and aluminum; worm gears are available in steel, hardened steel, stainless, lightweight aluminum, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring equipment called GEAR GAGES! Gear Gages reduce mistakes, save money and time when identifying and ordering gears. These pitch templates can be found in nine sets to identify all the common pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Good Pitches, Coarse Pitches and Uncommon Pitches. Make reference to the section on Equipment GAGES for catalog quantities when ordering.
