Solitary reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are reduced to slower speed requirements of several industrial machines in one 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 floor and polished alloy steel worm develops a clean, work hardened surface area on the bronze equipment. For this reason worm gears put on in and improve with prolonged service while additional gears are wearing out. EP offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible 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 which allows the transmission 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 proper meshing of the gear under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can offer custom velocity 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 allow EP to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our design also includes a hardened, floor and polished alloy metal worm. This combination develops a clean, work-hardened mating surface of the bronze gear which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet procedure and permits the likelihood of large velocity reductions. These gears are available from share in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for heavy 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 equipment reducer is one type of reduction gear package which consists of a worm pinion input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is normally used to take a rated motor acceleration and produce a low speed output with higher torque value based on the reduction ratio. They often can resolve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of velocity reducer because they offer 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 utilize a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical tests 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 can be found 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 rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric powered engine drives. You can choose to mount your NEMA motor to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft find our coupling section for choosing the coupling. We offer four assemblies left hand and right hands and double output shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures.

EP DDVM series triple-reduction worm gear swiftness reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes available on request). Output torque ranges from 33,000 in pounds. for the 7” CD DDVM-70 to 582,900 in lbs 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 thickeners and clarifiers, which need a vertical down shaft. Other available configurations also make EP triple reduction reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/sluggish speeds are needed.

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 cost solution to speed decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and provider factor for the application form. Click on “Specs” above for a table that will assist in determining the service factor. For service elements above 1.0, multiply the required torque by the support factor.
Our regular 700 Series – the heart of EP speed reducer product line – has been serving industry reliably for over 40 years. Its confirmed modular design has set the industry standard for performance and may be the most imitated product in the current worm gear acceleration reducer market. But why settle for a knock-off when you can have the original – from EP.
