One 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 takes a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient electric motor speeds are reduced to slower speed requirements of many industrial machines in a single 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 floor and polished alloy steel worm develops a simple, work hardened surface area on the bronze gear. Because of this worm gears wear in and improve with extented service while various other gears are deteriorating. 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 a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower amounts than are feasible with regular cast iron devices. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sized 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 new project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy steel worm. This combination develops a even, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides even and quiet operation and allows for the possibility of large rate 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 can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and the teeth. This increases 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 container which consists of a worm pinion insight, an output worm gear, and includes a right angle result orientation. This type of reduction gear box is generally used to have a rated motor velocity and produce a low speed result with higher torque value based on the decrease ratio. They often times can resolve space-saving problems since the worm equipment reducer is one of the sleekest decrease gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of swiftness reducer because they offer the greatest speed decrease in the tiniest 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 gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical testing equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides 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 of 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 gear reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electrical engine drives. You can choose to attach your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the result or input shaft find our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft insight and shaft output. Interchangeable with many worm gear manufactures.

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, still left or dual result shafts or a hollow bore output. 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 decrease and increased torque, with higher tolerances for shock loading than helical equipment 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 table that will assist in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the program factor.
