Single 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 takes 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 motor speeds are decreased to sluggish 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 provides for high efficiencies, and lengthy service life. The hardened floor and polished alloy steel worm develops a smooth, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with extented service while other gears are deteriorating. EP offers a broad 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 gear applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with regular cast iron units. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom swiftness and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy metal worm. This mixture develops a simple, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides simple and quiet operation and allows for the possibility of large quickness reductions. These gears are available from share 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 positioned in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost when compared to 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear package which contains a worm pinion input, an output worm gear, and includes a right angle output orientation. This kind of reduction gear container is generally used to have a rated motor swiftness and create a low speed output with higher torque worth based on the reduction ratio. They often can resolve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they provide the greatest speed decrease 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 common 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 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 of these options are produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm swiftness reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric powered motor drives. You can decide to install your NEMA engine to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double result shaft and shaft insight 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 models are 56C or 145TC flange mount with either right, left or dual result shafts or a hollow bore result. The indirect drive models 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 decrease 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 provider factor for the application. Click on “Specs” above for a desk that will assist in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
