Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The right angle set up of driving-to-driven machine takes 
a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are decreased to slow 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 existence. The hardened floor and polished alloy steel worm develops a easy, work hardened surface on the bronze gear. For this reason worm gears put on in and improve with extented service while other gears are wearing out. EP offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves severe shock loads or feasible 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 which allows the transmission of higher horsepower amounts than are feasible with standard cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom acceleration and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s acceleration reducer. Fabricated metal reducers enable EP to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our style also includes a hardened, ground and polished alloy metal worm. This combination develops a simple, work-hardened mating surface of the bronze equipment which increases with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides soft and quiet procedure and permits the likelihood of large rate reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and building allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth actions 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 some 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 gear reducer is one type of reduction gear package which includes a worm pinion insight, an output worm gear, and features a right angle result orientation. This type of reduction gear package is generally used to take a rated motor swiftness and create a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems since the worm gear reducer is among the sleekest decrease gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration 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 gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, protection 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 are available 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 tough compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Caractéristiques
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 better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also called worm gearbox or worm speed reducers. Worm gear reducers are utilized for speed decrease and raising the torque for electric motor drives. You can choose to mount your NEMA engine to the reducer utilizing the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft find our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures.

EP DDVM series triple-reduction worm gear quickness reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Result torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in pounds for the DDVM-200. Mechanical HP input requirements are from 0.09 HP for the 175,000:1 7 in CD reducer to 6.25 HP for the 5000:1 20” CD unit. These reducers can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are perfect for water/waste-water equipment drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make EP triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or components handling systems where huge torques/slow speeds are needed.
These reducers are also obtainable with a helical major reduction stage and so are termed the HDVM series

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 attach with either right, 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 provide 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 have to determine the required torque and provider factor for the application form. Click on “Specs” above for a table that will aid in determining the service factor. For service elements above 1.0, multiply the mandatory torque by the services factor.
