Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive use 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 ground and polished alloy metal worm develops a easy, work hardened surface on the bronze equipment. For this reason worm gears put on in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are possible with standard cast iron models. Extra heavy side 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 standard 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 direct drop-in alternative to a competitor’s acceleration reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, 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 design also incorporates a hardened, surface and polished alloy steel worm. This mixture develops a smooth, work-hardened mating surface of the bronze gear which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and permits the probability of large quickness reductions. These gears are available from share in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous worm gear speed reducer sliding tooth actions between worm and the teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of 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 equipment reducer is one type of reduction gear box which contains a worm pinion input, an output worm gear, and includes a right angle output orientation. This kind of reduction gear package is generally used to have a rated motor rate and create a low speed result with higher torque worth based on the decrease ratio. They often can resolve space-saving problems because the worm gear reducer is among the sleekest reduction gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that many 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 examining equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm equipment 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 tough compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading much better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm rate reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric powered motor drives. You can decide to mount your NEMA electric motor to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the output or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double output shaft and shaft insight and shaft result. 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 models are 56C or 145TC flange install with either right, left or dual output shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and provider factor for the application. Click on “Specifications” above for a table that will aid in identifying the service factor. For service elements above 1.0, multiply the required torque by the services factor.
