Solitary reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine takes a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are reduced to slower speed requirements of many 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 lengthy service life. The hardened floor and polished alloy metal worm develops a simple, work hardened surface on the bronze gear. For this reason worm gears put on in and improve with extented service while various other gears are wearing out. EP offers a wide selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) EP can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmission of higher horsepower levels than are possible with regular cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom rate and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s swiftness reducer. Fabricated steel reducers enable EP 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 EP reducers are manufactured from phosphorous bronze. Our design also includes a hardened, ground and polished alloy metal worm. This combination develops a soft, 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 simple and quiet operation and allows for the likelihood of large swiftness reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and construction allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a limited package size can be achieved 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 when compared to various 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 package which contains a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear package is generally used to have a rated motor quickness and produce a low speed result with higher torque value based on the decrease ratio. They often can resolve space-saving problems since the worm gear reducer is one of the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they offer the greatest speed reduction in the smallest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical testing 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 can be found 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 produced with rugged compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm velocity reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electric engine drives. You can decide to attach your NEMA motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft see our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double output shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to lessen 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 output boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and provider factor for the application. Click on “Specifications” above for a desk that will aid in determining the service factor. For service factors above 1.0, multiply the required torque by the assistance factor.
