Single reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine takes a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to slow speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened surface and polished alloy metal worm develops a smooth, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can offer 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 feasible with regular cast iron systems. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring proper 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 offer custom speed and reversed engineered reducers for the application, be it a new project or a direct drop-in alternative to a competitor’s acceleration reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct 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 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 class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and allows for the possibility of large velocity reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited 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 heavy loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear package which contains a worm pinion input, an output worm equipment, and features a right angle result orientation. This kind of reduction gear package is generally used to take a rated motor quickness and produce a low speed output with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems since the worm equipment reducer is 
among the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of acceleration reducer because they provide 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 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 offers two sizes of worm equipment reducer, the SW-1 and the SW-5 and both are available 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 durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow output shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm speed reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric engine drives. You can decide to mount your NEMA engine to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double output shaft and shaft insight and shaft result. Interchangeable with the majority of 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 attach with either right, left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use 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 gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and support factor for the application form. Click on “Specifications” above for a table that will assist in determining the service aspect. For service elements above 1.0, multiply the mandatory torque by the program factor.
