One reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient motor speeds are decreased to gradual speed requirements of many industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened surface and polished alloy metal worm develops a easy, work hardened surface area on the bronze equipment. For this reason worm gears use 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 products.
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 that allows the tranny of higher horsepower amounts than are possible with standard cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom speed and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s rate reducer. Fabricated metal reducers enable EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our design also includes a hardened, ground and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and permits the possibility of large swiftness reductions. These gears are available from stock in a wide variety of ratios, from as low as 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the 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 usage 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 equipment reducer is one kind of reduction gear box which includes a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This type of reduction gear package is generally used to have a rated motor velocity and produce a low speed output with higher torque worth based on the reduction ratio. They often can solve space-saving problems because the worm equipment reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of swiftness 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 many 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 tests 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 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 of these options are manufactured with durable 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 equipment reducers offer a choice of a good or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric engine drives. You can decide to mount your NEMA engine to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the result or input shaft see our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

EP DDVM series triple-reduction worm gear swiftness reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available 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 insight 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 well suited for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make EP triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/slower speeds are needed.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, left or dual result shafts or a hollow bore result. The indirect drive models 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 decide on 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 identifying the service element. For service elements above 1.0, multiply the required torque by the services factor.
