Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The right angle arrangement 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 arrangements adaptable to any installation requirement. Efficient motor speeds are reduced to slower speed requirements of many industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service life. The hardened surface and polished alloy steel worm develops a soft, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with extented service while other gears are deteriorating. EP offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) EP can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are possible with regular cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the gear under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can offer custom speed and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers enable EP to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in EP 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 area of the bronze equipment which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides easy and quiet procedure and permits the likelihood of large velocity reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear container which consists of a worm pinion insight, an output worm gear, and includes a right angle output orientation. This type of reduction gear package is generally used to have a rated motor rate and produce a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of acceleration reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems make use of a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical screening 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 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 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 solid or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm gear reducers are utilized for speed reduction and raising the torque for electric powered engine drives. You can decide to mount 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 find our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double output shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm gear reducers are found 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, remaining or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output 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 need to determine the required torque and program factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the required torque by the assistance factor.
