Single reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper angle set up 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 plans adaptable to any installation requirement. Efficient motor speeds are decreased to gradual speed requirements of many industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened surface and polished alloy steel worm develops a even, work hardened surface on the bronze equipment. For this reason worm gears use in and improve with extented service while various other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower amounts than are possible with standard cast iron units. Extra heavy side plates connect the worm and worm gear speed reducer equipment shaft bearing facilitates, assuring appropriate 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 quickness and reversed engineered reducers for your application, be it a new project or a primary drop-in alternative to a competitor’s speed 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 customer 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 metal worm. This combination develops a clean, work-hardened mating surface of the bronze gear which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides easy and quiet procedure and allows for 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 compact design and building allows worm gear reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size can be achieved 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 offer users high reducing convenience of relatively low cost when compared to some 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 make use of 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 output orientation. This type of reduction gear container is generally used to have a rated motor speed and produce a low speed result with higher torque value based on the reduction ratio. They often can resolve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of quickness reducer because they offer the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque output 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 can be found in tuning instruments, medical assessment 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 are available 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 produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also called worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed decrease and increasing the torque for electric engine drives. You can choose to attach your NEMA engine to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft find our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double result shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm gear 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, still 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 cost solution to speed decrease and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the required torque and services factor for the application form. Click on “Specs” above for a table that will assist in determining the service aspect. For service elements above 1.0, multiply the required torque by the services factor.
