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

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened surface and polished alloy metal worm develops a even, work hardened surface on the bronze gear. worm gear speed reducer Because of this worm gears put on 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 possible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with regular cast iron products. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated steel 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 fresh project or a direct drop-in alternative to a competitor’s velocity reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in replacement saving the client 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 steel worm. This combination develops a soft, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides easy and quiet procedure and permits the possibility of large rate reductions. These gears are available from share in a wide selection of ratios, from only 4:1 up to 3600:1. The small design and building 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 equipment features the constant sliding tooth actions between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with 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 type of reduction gear package which includes a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This type of reduction gear package is generally used to have a rated motor velocity and create a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of speed reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical tests 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 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 produced with durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow output shaft and feature an adjustable mounting position. 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 Equipment Reducers also known as worm gearbox or worm swiftness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electrical electric motor drives. You can choose to attach your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double result shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures. Observe data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment 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 versions are 56C or 145TC flange attach with either right, still left or dual output shafts or a hollow bore output. The indirect drive versions are shaft input-shaft result 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 gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and services factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the mandatory torque by the assistance factor.
