Solitary reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled compact drive. The proper angle set up 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 plans adaptable to any mounting requirement. Efficient engine speeds are decreased to slow 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 life. The hardened ground and polished alloy steel worm develops a simple, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower levels than are feasible with regular cast iron units. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also includes a hardened, ground and polished alloy steel worm. This combination develops a clean, work-hardened mating surface area of the bronze equipment which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet operation and allows for the likelihood of large quickness reductions. These gears can be found from share in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm equipment reducers to be placed in a comparatively small space. Thus, 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 escalates the tolerance for heavy loads and shock loads. Worm gear drives offer 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which includes a worm pinion insight, an output worm equipment, and features a right angle result orientation. This type of reduction gear package is generally used to take a rated motor swiftness and create a low speed result with higher torque value based on the reduction ratio. They often can solve space-saving problems because the worm gear reducer is among the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of velocity reducer because they offer the greatest speed decrease in the smallest package. With a higher 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 common applications for worm gears can be found in tuning instruments, medical assessment 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 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 rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is 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, nevertheless, can endure shock loading much better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric electric motor drives. You can decide to attach your NEMA engine to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double result shaft and shaft 
insight and shaft output. Interchangeable with many worm gear manufactures. See data sheet in product overview for diamensions. Unless you see your type, please Contact Us.

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 mount with either right, still left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and program factor for the application. Click on “Specifications” above for a table that will assist in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the program factor.
