Solitary reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled compact 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 arrangements adaptable to any mounting requirement. Efficient motor speeds are decreased to gradual speed requirements of several industrial machines in a single reduction.

The exclusive utilization 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 surface and polished alloy metal worm develops a even, work hardened surface area on the bronze gear. For this reason worm gears wear in and improve with prolonged service while various other 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 products applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with standard cast iron products. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom speed and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s speed reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute 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, surface and polished alloy metal worm. This mixture develops a even, work-hardened mating surface area of the bronze equipment which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and permits the likelihood of large velocity reductions. These gears can be found from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth action between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear box which consists of a worm pinion input, an output worm gear, and features a right angle result orientation. This kind of reduction gear container is normally 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 solve space-saving problems since the worm gear 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 favorite type of velocity reducer because they offer the greatest speed reduction 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 typical applications for worm gears are available in tuning instruments, medical tests equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers 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 tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm velocity reducers. Worm gear reducers are used for speed decrease and increasing the torque for electric engine drives. You can choose to attach your NEMA engine to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the output or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hand and right hands and double result shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm equipment 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 output. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low worm gear speed reducer 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 provider factor for the application. Click on “Specs” above for a desk that will assist in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the support factor.
