Solitary reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine requires a minimum of 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 reduced to slower speed requirements of several industrial machines in a single reduction.

The exclusive use 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 smooth, work hardened surface area on the bronze gear. For this reason worm gears put on in and improve with extented service while other gears are wearing out. Ever-Power offers a wide collection 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 gear applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmission of higher horsepower levels than are feasible with standard cast iron systems. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom velocity and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in alternative 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 metal worm. This combination develops a easy, work-hardened mating surface of the bronze equipment which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and allows for the likelihood of large rate reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth actions between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide 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 make use of 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 equipment, and includes a right angle result orientation. This kind of reduction gear package is normally used to have a rated motor speed and produce a low speed result with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems since the worm gear reducer is among the sleekest decrease gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of quickness reducer because they offer the greatest speed decrease in the smallest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical examining equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm gear 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 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 an option of a solid or hollow result shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electrical motor drives. You can choose to install your NEMA motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft see our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. 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 models are 56C or 145TC flange mount with either right, left or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and improved 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 provider factor for the application. Click on “Specifications” above for a table that will aid in determining the service factor. For service factors above 1.0, multiply the mandatory torque by the services factor.
