worm gear speed reducer

Solitary reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are reduced to gradual speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear worm gear speed reducer provides for high efficiencies, and long service existence. The hardened floor and polished alloy steel worm develops a easy, work hardened surface on the bronze gear. Because of this worm gears wear in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower levels than are possible with standard cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also includes a hardened, ground and polished alloy metal worm. This combination develops a simple, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and permits the probability of large acceleration reductions. These gears are available from share in a wide variety of ratios, from only 4:1 up to 3600:1. The small design and building allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth actions between worm and one’s teeth. This increases the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to various other types of gearing.
The use of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which consists of a worm pinion input, an output worm equipment, and features a right angle result orientation. This type of reduction gear box is normally used to take a rated motor speed and produce a low speed output with higher torque worth based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of velocity reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical testing equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm gear reducer, the SW-1 and the SW-5 and both can be found in a range of ratios. The SW-1 ratios include 3.5:1 to 60:1 and the SW-5 ratios include 5:1 to 100:1. Both these options are produced with durable compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow output shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm acceleration reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electrical motor drives. You can choose to install your NEMA motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hands and right hand and double result shaft and shaft insight and shaft output. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, left or dual output shafts or a hollow bore output. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and assistance factor for the application. Click on “Specifications” above for a desk that will assist in identifying the service aspect. For service factors above 1.0, multiply the required torque by the support factor.
