Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient engine speeds are decreased to slow speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened surface and polished alloy steel worm develops a simple, work hardened surface area on the bronze equipment. Because of this worm gears put on in and improve with extented service while various other gears are wearing out. EP offers a broad 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 provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmission of higher horsepower levels than are feasible with standard cast iron devices. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring correct meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can offer custom velocity and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the client 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 steel worm. This mixture develops a even, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides even and quiet procedure and permits the possibility of large quickness reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and building allows worm equipment reducers to be placed in a comparatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various other types of gearing.
The utilization of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear package which includes a worm pinion input, an output worm gear, and features a right angle result orientation. This type of reduction gear container is normally used to take a rated motor quickness and produce a low speed result with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed reducer because they offer the greatest speed decrease in the tiniest package. With a higher ratio of speed reduction 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, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers 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 manufactured with rugged compression-molded glass-fill 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 solid or hollow result shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading much better than other reduction gearbox designs, making them well suited 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 powered engine 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 find our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double output shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm gear 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 versions 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 make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed decrease 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 program factor for the application. Click on “Specs” above for a table that will aid in determining the service factor. For service factors above 1.0, multiply the mandatory torque by the service factor.
