Single reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The right angle set up of driving-to-driven machine requires a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient electric motor speeds are reduced to slower speed requirements of many 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 long service life. The hardened ground and polished alloy metal worm develops a even, work hardened surface area on the bronze equipment. For this reason worm gears use in and improve with prolonged service while other gears are wearing out. EP offers a wide collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile tools applications) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower levels than are possible with regular cast iron models. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, 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 speed and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers enable EP to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in substitute 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, floor and polished alloy metal worm. This combination develops a simple, work-hardened mating surface of the bronze equipment which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides soft and quiet operation and allows for the possibility of large quickness reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm gear reducers to be placed in a comparatively 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 actions between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for 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 use worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one type of reduction gear container which contains a worm pinion insight, an output worm equipment, and features a right angle output orientation. This type of reduction gear package is normally used to have a rated motor swiftness and create a low speed output with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of swiftness reducer because they provide 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 utilize a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical testing equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides 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 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, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm acceleration reducers. Worm gear reducers are utilized for speed decrease and raising the torque for electric powered electric 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 need a coupling for the result or input shaft find our coupling section for choosing the coupling. We offer four assemblies left hands 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 center distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in pounds. 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 installed.
These reducers are well suited for water/waste-water equipment drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other obtainable configurations also make EP triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where large torques/sluggish speeds are needed.
These reducers are also obtainable with a helical primary reduction stage and so are termed the HDVM series

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 install with either right, still left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction 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 required torque and service factor for the application form. Click on “Specs” above for a table that will assist in identifying the service factor. For service factors above 1.0, multiply the required torque by the program factor.
