Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine takes a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are decreased to slow speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened surface and polished alloy metal worm develops a smooth, work hardened surface on the bronze gear. Because of this worm gears use in and improve with prolonged service while other 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 offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower levels than are possible with regular cast iron units. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom rate and reversed engineered reducers for the application, be it a new project or a direct drop-in alternative to a competitor’s quickness reducer. Fabricated steel reducers enable EP to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement 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 clean, work-hardened mating surface area of the bronze gear which increases with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides even and quiet procedure and allows for the probability of large swiftness reductions. These gears are available from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and construction allows worm equipment 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 equipment features the constant sliding tooth actions between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost when compared to 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which contains a worm pinion input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is generally used to have a rated motor speed and produce a low speed output with higher torque value based on the decrease ratio. They often can solve space-saving problems because the worm gear reducer is among the sleekest decrease gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of acceleration 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 equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical assessment 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 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 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 good or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed decrease and increasing the torque for electrical engine drives. You can choose to install your NEMA motor to the reducer by using the NEMA C face flange or make use of a coupling. If you want a coupling for the output or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures.

EP DDVM series triple-reduction worm gear quickness reducers are available 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 are available in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water tools drive applications such as thickeners and clarifiers, which require a vertical 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 various other process or materials handling systems where huge torques/gradual speeds are needed.

Description
The HDR Series worm gear reducers are found 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 versions are 56C or 145TC flange install with either right, left or dual output 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 provide 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 program factor for the application. Click on “Specifications” above for a desk that will aid in identifying the service element. For service factors above 1.0, multiply the required torque by the provider factor.
