Single reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are reduced to slow 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 life. The hardened floor and polished alloy metal worm develops a even, work hardened surface on the bronze gear. For this reason worm gears use in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile tools 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 levels than are possible with regular cast iron products. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring proper 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 swiftness and reversed engineered reducers for the application, be it a new project or a primary drop-in replacement for a competitor’s speed reducer. Fabricated metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct 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 style also incorporates a hardened, floor and polished alloy steel worm. This mixture 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 right angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and permits the possibility of large acceleration reductions. These gears are available from share in a wide variety of ratios, from only 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 restricted package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth actions 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 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 applications that use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear container which contains a worm pinion input, an output worm equipment, and features a right angle result 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 value based on the reduction ratio. They often times can resolve space-saving problems because the worm gear reducer is among the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of quickness reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical examining 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 manufactured with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm velocity reducers. Worm gear reducers are utilized for speed decrease 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 use a coupling. If you want a coupling for the output or input shaft observe 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. See data sheet in item overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment 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, still left or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low priced solution to speed reduction and improved 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 mandatory torque and assistance factor for the application form. Click on “Specs” above for a table that will assist in identifying the service factor. For service factors above 1.0, multiply the required torque by the assistance factor.
