One reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine takes a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are decreased to gradual speed requirements of many industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened floor and polished alloy steel worm develops a smooth, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with prolonged service while various other gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower levels than are feasible with standard cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the apparatus under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom acceleration and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s rate reducer. Fabricated steel reducers allow 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 manufactured from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy steel worm. This combination develops a easy, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides soft and quiet operation and allows for the possibility of large velocity reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and construction allows worm gear reducers to be positioned in a comparatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to some 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear box which includes a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear package is normally used to have a rated motor speed and create a low speed output with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of speed reducer because they provide the greatest speed decrease in the tiniest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear 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 gear 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 durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s 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 decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric motor drives. You can decide to install your NEMA engine to the reducer utilizing the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double output shaft and shaft input and shaft output. Interchangeable with most 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 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 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water devices drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where huge torques/slower speeds are needed.

Description
The HDR Series worm equipment reducers are used 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 mount with either right, left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low priced 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 have to determine the mandatory torque and service factor for the application form. Click on “Specifications” above for a desk that will aid in identifying the service element. For service factors above 1.0, multiply the mandatory torque by the support factor.
