One reduction worm gearing offers high ratio reduction with few shifting 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 plans adaptable to any installation requirement. Efficient engine speeds are decreased to slow speed requirements of many 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 lengthy service existence. The hardened surface and polished alloy steel worm develops a smooth, work hardened surface area on the bronze gear. For this reason worm gears use in and improve with prolonged service while additional gears are deteriorating. EP offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) EP can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are possible with regular cast iron devices. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom swiftness and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s quickness reducer. Fabricated metal reducers enable EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our style also includes a hardened, floor and polished alloy steel worm. This combination develops a soft, 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 even and quiet operation and allows for the possibility of large swiftness reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and building allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm equipment 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 convenience of 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear container which includes a worm pinion insight, an output worm equipment, and features a right angle result orientation. This type of reduction gear container is normally used to have a rated motor swiftness and produce a low speed result with higher torque value based on the reduction ratio. They often times can resolve space-saving problems because the worm equipment reducer is among 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 quickness reducer because they offer the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems make use of a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical testing 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 of these options are produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are used 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 need a coupling for the output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures. See data sheet in item overview for diamensions. If you don’t see your type, make sure you Contact Us.

EP DDVM series triple-reduction worm gear rate reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available on request). Result torque ranges from 33,000 in pounds. for the 7” CD DDVM-70 to 582,900 in pounds for the DDVM-200. Mechanical HP insight 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 are available in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are well suited for water/waste-water tools drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other obtainable configurations also make EP triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where huge torques/sluggish speeds are needed.
These reducers are also obtainable with a helical major reduction stage and are termed the HDVM series

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions 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 result boxes for use with sprocket or pulley drive systems. They provide an effective low priced solution to speed decrease and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and program factor for the application form. Click on “Specifications” above for a desk that will aid in identifying the service factor. For service elements above 1.0, multiply the required torque by the assistance factor.
