Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires 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 electric motor speeds are decreased to slower speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened floor and polished alloy metal worm develops a clean, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with extented service while various other gears are wearing out. 
Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can offer fabricated steel housings with up to 48" center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower amounts than are possible with regular cast iron devices. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom rate and reversed engineered reducers for the application, be it a new project or a direct drop-in alternative to a competitor's acceleration reducer. Fabricated steel reducers enable Ever-Power to complement a competitor's footprint, centerline, and shaft height allowing a primary drop-in substitute saving the client time and money.
Long - Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy steel worm. This combination develops a simple, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and permits the possibility of large swiftness reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm gear reducers to be placed 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 constant sliding tooth action between worm and the teeth. This increases the tolerance for large loads and shock loads. Worm gear drives provide 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear container which consists of a worm pinion insight, an output worm equipment, and features a right angle result orientation. This kind of reduction gear package is generally used to have a rated motor quickness and create a low speed output with higher torque value based on the reduction ratio. They often times can solve space-saving problems because the worm gear reducer is among the sleekest decrease gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of swiftness reducer because they offer the greatest speed decrease in the tiniest package. With a high ratio of speed decrease and high torque result multiplier, it's unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most common 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 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 these options are manufactured with rugged 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 gear reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric motor drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C encounter flange or make use of 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 result. Interchangeable with the majority of worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear acceleration 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 lbs 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 are available in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water devices drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/slow speeds are needed.

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange install with either right, remaining or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and provider factor for the application form. Click on "Specifications" above for a desk that will assist in determining the service aspect. For service elements above 1.0, multiply the required torque by the assistance factor.
