One reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires 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 motor speeds are reduced to slower speed requirements of several industrial machines in 
one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened ground and polished alloy steel worm develops a smooth, work hardened surface on the bronze equipment. Because of this worm gears use in and improve with prolonged service while various other gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower levels than are possible with regular cast iron units. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom rate and reversed engineered reducers for the application, be it a new project or a primary drop-in replacement for a competitor’s quickness reducer. Fabricated steel reducers allow Ever-Power to match 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, floor and polished alloy steel worm. This mixture develops a clean, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides smooth and quiet operation and allows for the possibility of large quickness reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm gear reducers to be positioned in a relatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and the teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives provide 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear container which consists of a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear container is generally used to have a rated motor acceleration and produce a low speed output with higher torque value based on the reduction ratio. They often can solve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they provide the greatest speed decrease in the tiniest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical screening equipment, elevators, protection 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 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 rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed reduction and raising the torque for electrical electric motor drives. You can decide to install your NEMA electric motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double output shaft and shaft input and shaft output. Interchangeable with many 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 can be found in direct or indirect drive, direct drive models 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 result boxes for use 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 gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and assistance factor for the application. Click on “Specifications” above for a desk that will assist in identifying the service aspect. For service factors above 1.0, multiply the required torque by the provider factor.
