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

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service life. The hardened surface and polished alloy steel worm develops a smooth, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with extented service while other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower levels than are possible with regular 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 sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s rate reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, worm gear speed reducer centerline, and shaft height allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy steel worm. This combination develops a simple, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and allows for the likelihood of large quickness reductions. These gears can be found from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and structure allows worm equipment reducers to be placed in a comparatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives offer 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 equipment reducer is one type of reduction gear package which includes a worm pinion input, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear container is normally used to have a rated motor quickness and produce a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of quickness reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment reducer. Some of the most common 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 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 these options are manufactured with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm velocity reducers. Worm gear reducers are used for speed reduction and raising the torque for electric engine drives. You can choose to install your NEMA motor to the reducer by using the NEMA C face 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 hand and right hands and double output shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures. Observe data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

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 versions are 56C or 145TC flange mount with either right, left or dual output 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 provide an effective low cost solution to speed decrease and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and program factor for the application form. Click on “Specs” above for a desk that will assist in determining the service element. For service factors above 1.0, multiply the required torque by the assistance factor.
