Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle set up 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 arrangements adaptable to any installation requirement. Efficient electric motor speeds are reduced to gradual speed requirements of many industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service existence. The 
hardened surface and polished alloy steel worm develops a simple, work hardened surface area on the bronze equipment. Because of this worm gears wear in and improve with extented 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 the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with standard cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring proper meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom quickness and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s acceleration reducer. Fabricated steel reducers enable EP to complement a competitor’s footprint, centerline, and shaft elevation 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 style also incorporates a hardened, surface and polished alloy steel worm. This mixture develops a easy, work-hardened mating surface area of the bronze equipment which boosts with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet procedure and permits the possibility of large speed reductions. These gears are available from share in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth actions between worm and one’s teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to 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 gear reducer is one kind of reduction gear container which includes a worm pinion insight, an output worm gear, and includes a right angle output orientation. This kind of reduction gear container is normally used to take a rated motor quickness and produce a low speed result with higher torque value based on the reduction ratio. They often can resolve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of quickness reducer because they offer the greatest speed decrease in the tiniest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical examining 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 up polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm rate reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric electric motor drives. You can choose to attach your NEMA engine 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 observe our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with the majority of worm gear manufactures.

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). Output torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in lbs 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 mounted.
These reducers are well suited for water/waste-water tools drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make EP triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/gradual speeds are needed.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for make use of 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 have to determine the required torque and assistance factor for the application form. Click on “Specs” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the mandatory torque by the support factor.
