Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are reduced to slow speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened floor and polished alloy metal worm develops a even, work hardened surface area on the bronze gear. Because of this worm gears put on in and improve with extented service while additional gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can provide 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 possible with regular cast iron systems. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular 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 primary drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a primary 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, surface and polished alloy metal worm. This combination develops a easy, work-hardened mating surface of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides even and quiet procedure and allows for 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 compact design and construction 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 gear features the constant sliding tooth actions between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost when compared to various 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear box which contains a worm pinion input, an output worm gear, and features a right angle output orientation. This type of reduction gear box is generally used to take a rated motor swiftness and produce a low speed output with higher torque worth based on the reduction ratio. They often can solve 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 acceleration reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed reduction 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 common 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 gear reducer, the SW-1 and the SW-5 and both are available 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 these options are produced with tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric engine drives. You can choose to attach your NEMA engine to the reducer utilizing the NEMA C encounter flange or use a coupling. If you want a coupling for the output or input shaft find our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft insight and shaft output. Interchangeable with many worm gear manufactures.

Ever-Power 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 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 installed.
These reducers are ideal for water/waste-water gear drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/sluggish speeds are needed.

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 versions are 56C or 145TC flange attach with either right, still left or dual result 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 cost solution to speed decrease 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 services factor for the application form. Click on “Specs” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the required torque by the assistance factor.
