servo worm reducer

EP offers a complete range of modular servo gearboxes /worm reducers. The modular style allows for configurations with motor suggestions flange and result pinion for rack and pinion drives, together with solid productivity shafts, Hollow bore end result, and source shafts for all other positioning applications. The modular design allows for universal mounting of the gearbox in virtually any orientation.
Servo-Worm Reducers were especially developed for work with with the most recent servo motors found in applications that demand exact positioning and repeatability.
These reducers are ideal for applications in materials handling, automation, machine tool, and robotics.
The light weight modular aluminum housing design allows for easy machine integration, and excellent heat dissipation. A multitude of source flanges and couplings can be found to permit easy mounting of nearly any servo-motor and custom made flanges can be accommodated. Output configurations with pinion, hollow bore, or sound shaft are available and will be configured for input with motor flange, no cost type shaft, or both free input shaft and electric motor flange.

High-Torque (HT) Servo-Worm Reducers
This standard range of Servo-Worm Reducers are simply perfect for use in applications that demand high repeatability, precise positioning and performance. They were specifically developed for make use of with state-of-the-art servo electric motor technology, providing tight integration of the engine to the machine. Angular backlash of less than 1 arc-a few minutes is provided standard.
They can be purchased in four sizes (50 mm to 100 mm center length) 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 broad range of engine couplings and mounting flanges are for sale to assembly to nearly all servo motors, and the hollow bore result can be utilised to mount outcome 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, Machine Tool, Robotics and Aerospace.
Gearing: Internal gear style was optimized to provide an angular backlash of significantly less than 1 arc-minutes in assembly, with the choice of “in the field” adjustable backlash if necessary.
Bearings: Input angular get in touch with bearings for high insight speed, and robust end result tapered-roller bearings for great radial and axial load capability.
Housing: Aluminium housing for good heat dissipation, with integral suggestions flange for servo motors and common mounting on any encounter.
Output: The output bore is available with a good compression-type hub or a ISO 9409-1 flange (see dimension web pages). We offer a line of components 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 only minimizes backlash but also eliminates back-driving the gearmotor so a position can be placed even when power isn’t applied. The precision surface 3/8” stainless steel end result shaft is supported by dual 3/8” ABEC 5 ball bearings to aid a load from any orientation. The ¼” ABS plastic and aluminum structure provides a rigid framework without adding unnecessary weight and is quickly mounted to any flat work surface by utilizing the base mounting tabs. Our Regular Spur Gear motors will work with this gearbox (engine offered separately). The Vertical Shaft Worm-Drive Gearbox is 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 (in max speed)
now offers an economical right position gearhead for use with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers happen to be most appropriate for basic motion and insight speeds of 2000 rpm where profile application costs are a major consideration.

Worm Gears are best angle drives providing large speed ratios on comparatively short center distances from 1/4” to 11”. When effectively mounted and lubricated they function as the quietist and smoothest operating type of gearing. Due to the high ratios likely with worm gearing, optimum speed reduction could be accomplished in less space than 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 sizable degree on the helix angle of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% better than solitary thread worms. The mesh or engagement of worms with worm gears creates a sliding action leading to considerable friction and greater lack of efficiency beyond other types of gearing. The make use of hardened and floor worm swith bronze worm gears increases efficiency.
LUBRICATION can be an essential factor to improve efficiency in worm gearing. Worm equipment action generates considerable warmth, decreasing efficiency. The number of electricity transmitted at confirmed temperature boosts as the efficiency of the gearing boosts. Proper lubrication enhances efficiency by lowering friction and heat.
RATIOS of worm equipment sets are determined by dividing the amount of teeth in the apparatus by the number of threads. Thus solo threads yield higher ratios than multiple threads. All EP. worm gear sets are available with either still left or right side threads. EP. worm equipment sets can be found with Qua, Double, Triple and Single-druple Threads.
Safe practices PROVISION: Worm gearing should not be used as a locking mechanism to hold heavy weights where reversing actions could cause harm or injury. In applications where potential injury is nonexistent and self-locking is desired against backward rotation in that case use of an individual thread worm with a minimal helix angle instantly locks the worm gear get against backward rotation.
MATERIAL recommended for worms is usually hardened steel and bronze for worm gears. Even so, depending on the application unhardened metal worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. Furthermore to steel and hardenedsteel, worms can be found in stainless, nylon, lightweight aluminum and bronze; worm gears are available in steel, hardened metal, stainless, aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring products called Equipment GAGES! Gear Gages lessen mistakes, save money and time when identifying and buying gears. These pitch templates can be purchased in nine sets to recognize all the normal pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Fine Pitches, Coarse Pitches and Uncommon Pitches. Make reference to the section on GEAR GAGES for catalog quantities when ordering.
