worm gear speed reducer
Single reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are reduced to slow speed requirements of many industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service lifestyle. The hardened surface and polished alloy steel worm develops a easy, work hardened surface area on the bronze equipment. Because of this worm gears put on in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmission of higher horsepower amounts than are possible with standard cast iron models. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom acceleration and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s rate reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy metal worm. This combination develops a clean, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides easy and quiet operation and permits the likelihood of large speed reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and structure allows worm gear reducers to be placed in a comparatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various other types of gearing.
The usage 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 box which includes a worm pinion insight, an output worm equipment, and features a right angle result orientation. This type of reduction gear container is generally used to take a rated motor speed and produce a low speed result with higher torque worth based on the reduction ratio. They often can solve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of quickness reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems make use of a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical testing equipment, elevators, security 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 variety 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 of these options are produced with tough compression-molded glass-fill polyester housings for a long lasting, 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 result shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm speed reducers. Worm gear reducers are used for speed reduction and increasing the torque for electrical engine drives. You can decide to mount your NEMA engine to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the output or input shaft discover our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. See data sheet in product overview for diamensions. Unless you see your type, please Contact Us.

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange mount with either right, left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and improved 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 services factor for the application. Click on “Specs” above for a desk that will assist in determining the service factor. For service elements above 1.0, multiply the required torque by the service factor.
