High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are simply perfect for use in applications that demand high precise positioning, performance and repeatability. They were especially developed for work with 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-mins is provided standard.
They can be purchased in four sizes (50 mm to 100 mm center range) 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 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 productivity 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 digital line shafting. Industries offered include Material H, ling, Machine Application, Automation, Aerospace and Robotics.
Gearing: Internal gear style was optimized to supply an angular backlash of less than 1 arc-minutes at assembly, with the choice of \u201cin the discipline\u201d adjustable backlash if necessary.
Bearings: Input angular get in touch with bearings for high input speed, and robust end result tapered-roller bearings for high radial and axial load capability.
Housing: Aluminium housing once and for all heat dissipation, with integral insight flange for servo motors and general mounting on any deal with.
Output: The output bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension pages). We offer a line of add-ons to adapt 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 likewise eliminates back-driving the gearmotor so a posture can be held even when power isn’t applied. The precision surface 3\/8\u201d stainless steel result shaft is supported by dual 3\/8\u201d ABEC 5 ball bearings to aid lots from any orientation. The \u00bc\u201d ABS plastic and lightweight aluminum structure offers a rigid framework without adding pointless weight and is conveniently installed to any flat surface by utilizing the bottom mounting tabs. Our Standard Spur Gear motors will work with this gearbox (engine distributed separately). The Vertical Shaft Worm-Drive Gearbox is simply perfect for turn-tables, time-lapse devices and low-acceleration applications that require high precision 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 (at max speed)
now provides an economical right position gearhead for work with with small NEMA 23 through 56 and similar small metric servo and stepper motors. These reducers will be best suited for basic movement and insight speeds of 2000 rpm where profile request costs are a major consideration.

Worm Gears are right angle drives providing large quickness ratios on comparatively short center distances from 1\/4\u201d to 11\u201d. When correctly installed and lubricated they function as the quietist and smoothest jogging type of gearing. Because of the high ratios possible with worm gearing, maximum speed reduction can be accomplished in much less space than a great many other types of gearing. Worm and worm gears are powered by non-intersecting shafts at 90\u00b0 angles.
EFFICIENCY of worm equipment drives depends to a huge extent on the helix angle 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 makes a sliding action creating considerable friction and higher lack of efficiency beyond other styles of gearing. The utilization of hardened and surface worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to improve efficiency found in worm gearing. Worm gear action generates considerable high temperature, decreasing efficiency. How much power transmitted at a given temperature boosts as the efficiency of the gearing raises. Proper lubrication enhances efficiency by minimizing friction and heat.
RATIOS of worm equipment sets are determined by dividing the quantity of teeth in the gear by the number of threads. Thus solitary threads yield higher ratios than multiple threads. All EP. worm gear sets are available with either left or right hands threads. EP. worm gear sets can be found with Double, Qua, Triple and Single-druple Threads.
SAFETY PROVISION: Worm gearing should not be used as a good locking mechanism to hold heavy weights where reversing actions can cause harm or injury. In applications where potential harm is non-existent and self-locking is desired against backward rotation then use of an individual thread worm with a low helix angle immediately locks the worm equipment drive against backward rotation.
MATERIAL recommended for worms is definitely hardened steel and bronze for worm gears. Nevertheless, depending on the application unhardened steel worms operate adequately and considerably more economically with cast iron worm gears at 50% horsepower ratings. In addition to steel and hardenedsteel, worms can be purchased in bronze, aluminium, stainless and nylon; worm gears can be purchased in steel, hardened metal, stainless, metal, nylon and non-metallic (phenolic).
EP also sells gear tooth measuring equipment called Equipment GAGES! Gear Gages lessen mistakes, save time and money when identifying and ordering gears. These pitch templates can be found in nine sets to recognize all the common pitch sizes: Diametral Pitch \u201cDP\u201d, Circular Pitch \u201cCP\u201d, Exterior Involute Splines, Metric Module \u201cMOD\u201d, Stub Tooth, Excellent Pitches, Coarse Pitches and Unusual Pitches.
