One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The right angle set up of driving-to-driven machine takes a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are decreased to slow speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened ground and polished alloy steel worm develops a easy, work hardened surface on the bronze gear. Because of this worm gears wear 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 the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can provide 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 models. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the gear under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s rate 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 customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, ground and polished alloy steel worm. This combination develops a simple, work-hardened mating surface of the bronze gear which increases with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides soft and quiet procedure and permits the likelihood of large rate reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The small design and building allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a limited 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 large loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with some other types of gearing.
The use 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 box which includes a worm pinion input, an output worm gear, and features a right angle result orientation. This type of reduction gear box is generally used to take a rated motor swiftness and create a low speed result with higher torque worth based on the decrease ratio. They often can resolve space-saving problems since the worm gear reducer is among the sleekest decrease gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems make use of a worm gear reducer. Some of the most typical 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 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 of these options are produced with durable compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also called worm gearbox or worm quickness reducers. Worm gear reducers are used for speed decrease and increasing the torque for electric electric motor drives. You can decide to install your NEMA motor to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hand and right hands and double output shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear swiftness reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in pounds for the DDVM-200. Mechanical HP input requirements are from 0.09 HP for the 175,000:1 7 in CD reducer to 6.25 HP for the 5000:1 20” CD unit. These reducers can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/slow speeds are needed.
These reducers are also available with a helical major reduction stage and so are termed the HDVM series

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available 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 output. The indirect drive versions 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 have to determine the required torque and program factor for the application. Click on “Specs” 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.
