servo worm reducer

EP offers a full range of modular servo gearboxes /worm reducers. The modular style allows for configurations with motor input flange and productivity pinion for rack and pinion drives, and also solid end result shafts, Hollow bore output, and input shafts for all the positioning applications. The modular style allows for universal mounting of the gearbox in virtually any orientation.
Servo-Worm Reducers were especially 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 material handling, automation, machine tool, and robotics.
The light weight modular aluminum housing design permits easy machine integration, and excellent heat dissipation. A wide variety of insight flanges and couplings can be found to allow easy mounting of almost any servo-motor and tailor made flanges could be accommodated. Productivity configurations with pinion, hollow bore, or stable shaft are available and can be configured for type with motor flange, free of charge source shaft, or both free input shaft and electric motor flange.

High-Torque (HT) Servo-Worm Reducers
This standard selection of Servo-Worm Reducers are perfect for use in applications that demand high performance, repeatability and precise positioning. They were particularly developed for work with with state-of-the-art servo motor technology, providing limited integration of the motor 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 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 variety of motor couplings and mounting flanges are available for assembly to almost all servo motors, and the hollow bore output can be utilized to mount result shafts, pinion shafts, or other drive elements.
Normal applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives, zero-backlash axis drives and electronic line shafting. Industries offered include Material H, ling, Automation, Aerospace, Machine Program and Robotics.
Gearing: Internal gear style was optimized to provide an angular backlash of less than 1 arc-minutes at assembly, with the option of “in the field” adjustable backlash if necessary.
Bearings: Input angular get in touch with bearings for high type speed, and robust outcome tapered-roller bearings for great radial and axial load capacity.
Housing: Light weight aluminum housing for good heat dissipation, with essential suggestions flange for servo motors and common mounting on any deal with.
Output: The end result bore is available with a good compression-type hub or a good ISO 9409-1 flange (see dimension internet pages). We provide a line of gadgets to adapt these outputs to straight shafting, Rack & Pinions, or other gearing types.
This gearbox utilizes a 30:1 ratio worm-get reduction for applications that want extremely slow and smooth rotational motion. The worm-drive design not only minimizes backlash but as well eliminates back-driving the gearmotor so a posture can be held even when power isn’t applied. The precision surface 3/8” stainless steel end result shaft is reinforced by dual 3/8” ABEC 5 ball bearings to aid lots from any orientation. The ¼” ABS plastic and lightweight aluminum structure provides a rigid framework without adding pointless weight and is conveniently mounted to any flat surface by utilizing the base mounting tabs. Our Common Spur Gear motors will continue to work with this gearbox (electric motor sold separately). The Vertical Shaft Worm-Drive Gearbox is perfect for turn-tables, time-lapse devices and low-acceleration applications that require high precision and torque.
Motor RPM required = 1 / (a few minutes per rotation desired / 30)
Example: 1 / (ten minutes per rotation / 30) = 3 RPM motor needed to achieve 10 minutes per rotation (at max speed)
now provides an economical right position gearhead for work with with small NEMA 23 through 56 and similar compact metric servo and stepper motors. These reducers happen to be best suited for basic movement and type speeds of 2000 rpm where profile application costs certainly are a major consideration.

Worm Gears are right angle drives providing huge swiftness ratios on comparatively short center distances from 1/4” to 11”. When effectively attached and lubricated they function as quietist and smoothest running type of gearing. Due to high ratios feasible with worm gearing, maximum speed reduction can be accomplished in much less space than 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 big extent on the helix position of the worm. Multiple thread worms and gears with bigger helix angle prove 25% to 50% better than single thread worms. The mesh or engagement of worms with worm gears generates a sliding action causing considerable friction and greater lack of efficiency beyond other styles of gearing. The usage of hardened and ground worm swith bronze worm gears increases efficiency.
LUBRICATION is an essential factor to improve efficiency in worm gearing. Worm equipment action generates considerable high temperature, decreasing efficiency. The volume of electricity transmitted at confirmed temperature boosts as the proficiency of the gearing increases. Proper lubrication enhances efficiency by lowering friction and heat.
RATIOS of worm gear sets are dependant on dividing the amount of teeth in the gear by the number of threads. Thus solo threads yield larger ratios than multiple threads. All EP. worm gear sets can be found with either left or right hands threads. EP. worm gear sets are offered with Double, Qua, Triple and Single-druple Threads.
SAFETY PROVISION: Worm gearing shouldn’t be used as a good locking mechanism to carry major weights where reversing actions can cause harm or personal injury. In applications where potential damage is nonexistent and self-locking is desired against backward rotation in that case use of a single thread worm with a minimal helix angle automatically locks the worm equipment get against backward rotation.
Materials recommended for worms is certainly hardened steel and bronze for worm gears. However, depending on the application unhardened steel worms operate adequately and even more economically with cast iron worm gears at 50% horsepower ratings. In addition to steel and hardenedsteel, worms are available in nylon, bronze, stainless and aluminum; worm gears can be purchased in steel, hardened steel, stainless, light weight aluminum, nylon and non-metallic (phenolic).
EP also sells equipment tooth measuring gadgets 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 identify all the standard pitch sizes: Diametral Pitch “DP”, Circular Pitch “CP”, Exterior Involute Splines, Metric Module “MOD”, Stub Tooth, Fine Pitches, Coarse Pitches and Unusual Pitches. Refer to the section on Equipment GAGES for catalog amounts when ordering.
