EP offers a complete selection of modular servo gearboxes /worm reducers. The modular style permits configurations with motor type flange and end result pinion for rack and pinion drives, along with solid end result shafts, Hollow bore output, and suggestions shafts for all other positioning applications. The modular style allows for general mounting of the gearbox in virtually any orientation.
Servo-Worm Reducers were particularly developed for use with the most recent servo motors in applications that demand specific positioning and repeatability.
These reducers are well suited for applications in materials handling, automation, equipment tool, and robotics.

High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are perfect for use in applications that demand high repeatability, precise positioning and performance. They were particularly developed for work with with state-of-the-art servo engine technology, providing limited integration of the engine to the machine. Angular backlash of less than 1 arc-minutes is provided standard.
They can be purchased in four sizes (50 mm to 100 mm center range) 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 motor couplings and mounting flanges are for sale to assembly to nearly all servo motors, and the hollow bore result can be utilised to mount productivity shafts, pinion shafts, or other drive elements.
Common 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 Instrument and Robotics.
Gearing: Internal gear style was optimized to provide an angular backlash of significantly less than 1 arc-minutes at assembly, with the choice of “in the discipline” adjustable backlash in the event necessary.
Bearings: Input angular get in touch with bearings for high suggestions speed, and robust output tapered-roller bearings for large radial and axial load ability.
Housing: Aluminium housing once and for all heat dissipation, with integral insight flange for servo motors and common mounting on any face.
Output: The end result bore is available with a good compression-type hub or a good ISO 9409-1 flange (see dimension pages). We give you a line of extras to adjust these outputs to straight 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-generating the gearmotor so a posture can be kept even when power is not applied. The precision ground 3/8” stainless steel outcome 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 attached to any flat surface by utilizing the bottom mounting tabs. Our Typical Spur Gear motors will work with this gearbox (electric motor offered separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse systems and low-acceleration applications that require high precision and torque.
Motor RPM required = 1 / (minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve ten minutes per rotation (at 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 are most appropriate for basic movement and type speeds of 2000 rpm where profile request costs are a major consideration.

Worm Gears are best suited angle drives providing significant acceleration ratios on comparatively short center distances from 1/4” to 11”. When effectively installed and lubricated they function as the quietist and smoothest working type of gearing. Due to high ratios likely with worm gearing, optimum speed reduction can be accomplished in less 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 equipment drives depends to a large degree on the helix angle of the worm. Multiple thread worms and gears with larger helix angle prove 25% to 50% better than one thread worms. The mesh or engagement of worms with worm gears generates a sliding action leading to considerable friction and better lack of efficiency beyond other types of gearing. The usage of hardened and surface worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to improve efficiency found in worm gearing. Worm equipment action generates considerable heating, decreasing efficiency. The volume of power transmitted at confirmed temperature increases as the proficiency of the gearing increases. Proper lubrication enhances productivity by lowering friction and heat.
RATIOS of worm gear sets are determined by dividing the number of teeth in the apparatus by the amount of threads. Thus sole threads yield bigger ratios than multiple threads. All EP. worm equipment sets are available with either left or right hands threads. EP. worm gear sets can be found with Solitary, Double, Qua and Triple-druple Threads.
Safe practices PROVISION: Worm gearing shouldn’t be used as a locking mechanism to carry heavy weights where reversing action could cause harm or damage. In applications where potential injury is non-existent and self-locking is preferred against backward rotation then use of an individual thread worm with a minimal helix angle immediately locks the worm equipment get against backward rotation.
MATERIAL recommended for worms is normally hardened steel and bronze for worm gears. However, depending on the application unhardened steel worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to metal and hardenedsteel, worms are available in nylon, bronze, metal and stainless; worm gears can be purchased in steel, hardened steel, stainless, lightweight aluminum, nylon and nonmetallic (phenolic).
EP also sells equipment tooth measuring devices called GEAR GAGES! Gear Gages lessen mistakes, save time and money when identifying and buying gears. These pitch templates can be found in nine sets to identify all the typical 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 GEAR GAGES for catalog figures when ordering.
