Solitary reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine requires a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are reduced to gradual 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 long service life. The hardened surface and polished alloy metal worm develops a even, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with prolonged service while other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower amounts than are feasible with standard cast iron devices. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the apparatus 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 rate and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the client 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 steel worm. This combination develops a simple, work-hardened mating surface area of the bronze equipment which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides smooth and quiet operation and allows for the probability of large speed reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The small design and construction allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth actions between worm and the teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with various other types of gearing.
The utilization 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 container which includes a worm pinion insight, an output worm gear, and features a right angle output orientation. This kind of reduction gear package is normally used to have a rated motor acceleration and produce a low speed output with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite 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 make use of a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical screening equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm equipment 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 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 an option of a solid or hollow output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric powered engine drives. You can decide to install your NEMA motor to the reducer by using the NEMA C face flange or make use of a coupling. If you want 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 hand 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 can be found 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 lbs 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
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 reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/sluggish speeds are needed.
These reducers are also offered 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 reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, still left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for use 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 equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the required torque and services factor for the application. Click on “Specs” above for a table that will assist in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the support factor.
Our standard 700 Series – the heart of Ever-Power swiftness reducer product line – has been serving industry reliably for over 40 years. Its verified modular design has set the market standard for performance and may be the most imitated product in today’s worm gear speed reducer market. But why settle for a knock-off when you’re able to have the original – from Ever-Power.
