Single reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to gradual speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened surface and polished alloy metal worm develops a smooth, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with extented service while other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and components 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 devices 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 transmitting of higher horsepower levels than are possible with standard cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the gear under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom velocity and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also includes a hardened, ground and polished alloy steel worm. This mixture develops a clean, work-hardened mating surface area of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides smooth and quiet operation and allows for the likelihood of large speed reductions. These gears can be found 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 gear reducers to be positioned in a comparatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various other types of gearing.
The use of worm gearing extends across many industries including food, beverage and grain and has many applications. Some worm gear speed reducer applications that use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which consists of a worm pinion insight, an output worm gear, and features a right angle result orientation. This kind of reduction gear box is generally used to take a rated motor velocity and produce a low speed output with higher torque worth based on the reduction ratio. They often can resolve space-saving problems since the worm gear reducer is among the sleekest decrease gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of rate reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical screening 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 can be found 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 polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow output shaft and show 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 Equipment Reducers also called worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electrical engine drives. You can decide to install your NEMA engine 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 see our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double output shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures. Observe data sheet in item overview for diamensions. Unless you see your type, please Contact Us.

Ever-Power DDVM series triple-reduction worm gear velocity reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in lbs. 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are well suited for water/waste-water gear drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other offered configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where huge torques/slow speeds are needed.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, left or dual result shafts or a hollow bore result. 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 increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and assistance factor for the application form. Click on “Specifications” above for a table that will aid in determining the service aspect. For service factors above 1.0, multiply the required torque by the service factor.
