One reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled small drive. The right angle set up of driving-to-driven machine takes a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to slow speed requirements of several 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 life. The hardened floor and polished alloy metal worm develops a smooth, work hardened surface area on the bronze gear. Because of this worm gears use in and improve with prolonged service while various other gears are deteriorating. EP offers a broad selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile products applications) EP can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the tranny of higher horsepower amounts than are possible with regular cast iron models. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring correct meshing of the apparatus under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom velocity and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor's speed reducer. Fabricated metal reducers allow EP to match 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 incorporates a hardened, ground and polished alloy steel worm. This combination develops a smooth, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet procedure and allows for the likelihood of large velocity reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The compact design and building allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth action between worm and one's teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various 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 contains a worm pinion input, an output worm gear, and includes a right angle result orientation. This type of reduction gear package is generally used to take a rated motor acceleration and create a low speed result 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 favorite type of speed reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed decrease and high torque output 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 examining equipment, elevators, protection 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 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 these options are produced with tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow result shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electric powered motor drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C face 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 result shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures. Observe data sheet in item overview for diamensions. Unless you see your type, please Contact Us.

EP DDVM series triple-reduction worm gear velocity 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). 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 installed.
These reducers are well suited for water/waste-water tools drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other offered 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 large torques/gradual speeds are needed.
These reducers are also obtainable with a helical main reduction stage and so are termed the HDVM series

Description
The HDR Series worm equipment reducers are found 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 result shafts or a hollow bore output. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced 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 need to determine the required torque and assistance factor for the application. Click on “Specifications” above for a desk that will assist in determining the service element. For service elements above 1.0, multiply the required torque by the program factor.
