Single reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient electric motor speeds are decreased to slow speed requirements of many industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service lifestyle. The hardened floor and polished alloy steel worm develops a smooth, work hardened surface on the bronze gear. For this reason worm gears wear in and improve with extented service while additional gears are wearing out. EP offers a broad collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile products 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 possible with regular cast iron products. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring proper 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 swiftness and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s acceleration reducer. Fabricated steel reducers allow EP to match a competitor’s footprint, centerline, and shaft height allowing a direct 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 incorporates a hardened, ground and polished alloy steel worm. This combination develops a clean, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and allows for the probability of large swiftness 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 structure allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for heavy 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 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 gear reducer is one type 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 box is normally used to have a rated motor acceleration and produce a low speed result with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems since the worm gear reducer is one of the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of velocity reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease 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 can be found in tuning instruments, medical testing equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides 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 durable compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow result shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, nevertheless, can endure shock loading much better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm speed reducers. Worm equipment reducers are used for speed reduction and raising the torque for electric powered motor drives. You can decide to install your NEMA electric motor 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. You can expect four assemblies left hand and right hand and double output shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures.

EP DDVM series triple-reduction worm gear rate reducers can be found in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes on request). Output 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 perfect for water/waste-water equipment drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other obtainable configurations also make EP triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/slower speeds are needed.
These reducers are also offered with a helical main 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 reduce speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive models are 56C or 145TC flange mount 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 offer an effective low cost solution to speed decrease and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and provider factor for the application. Click on “Specs” above for a table that will aid in determining the service factor. For service elements above 1.0, multiply the required torque by the assistance factor.
