One reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and result shafts can be extended 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 a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service life. The hardened ground and polished alloy metal worm develops a soft, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while various other gears are deteriorating. EP offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are possible with regular cast iron units. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated steel 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 new 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 elevation allowing a direct drop-in replacement saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced 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 equipment which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides soft and quiet procedure and permits the likelihood of large acceleration reductions. These gears are available from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and the teeth. This increases the tolerance for heavy 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 use 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 consists of a worm pinion input, an output worm gear, and features a right angle output orientation. This kind of reduction gear container is normally used to take a rated motor quickness and create a low speed result with higher torque value based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is one of 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 rate reducer because they offer the greatest speed reduction in the tiniest package. With a higher 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 common applications for worm gears are available in tuning instruments, medical examining 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 of these options are produced with rugged compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand 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 rate reducers. Worm gear reducers are used for speed reduction and raising the torque for electric powered electric motor drives. You can choose to attach your NEMA engine to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft see our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures. See data sheet in item overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm gear reducers are used 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 attach with either right, remaining or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and services factor for the application form. Click on “Specs” above for a table that will aid in identifying the service factor. For service elements above 1.0, multiply the required torque by the program factor.
