worm gear speed reducer

One reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient 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 provides for high efficiencies, and lengthy service existence. The hardened surface and polished alloy steel worm develops a even, work hardened surface on the bronze equipment. For this reason worm gears put on in and improve with extented service while other gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment 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 possible with regular cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring proper 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 provide custom rate and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also includes a hardened, floor and polished alloy metal worm. This combination develops a even, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet operation and allows for the likelihood of large speed reductions. These gears are available from share in a wide variety of ratios, from as low as 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 continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to 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 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 gear, and features a right angle result orientation. This type of reduction gear package is normally used to take a rated motor quickness and produce a low speed result with higher torque value based on the reduction ratio. They often can resolve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of rate reducer because they provide 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 common applications for worm gears are available in tuning instruments, medical tests 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 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 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 an option of a good or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading much better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm velocity reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric engine drives. You can decide to install your NEMA engine to the reducer by using the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hand and right hands and double output shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm gear reducers are used 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 output shafts or a hollow bore result. 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 priced solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will need 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 required torque by the program factor.
