One reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are reduced to gradual 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 offers high efficiencies, and long service life. The hardened ground and polished alloy metal worm develops a soft, work hardened surface area on the bronze gear. Because of this worm gears use in and improve with extented service while various other gears are wearing out. EP offers a wide collection of model configurations, sizes, ratios, and add-ons 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 devices applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with regular cast iron devices. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can offer custom rate and reversed engineered reducers for the application, be it a new project or a direct drop-in alternative to a competitor’s rate reducer. Fabricated metal reducers enable EP to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute 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, surface and polished alloy metal worm. This combination develops a soft, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides soft and quiet procedure and permits the likelihood of large swiftness reductions. These gears can be found from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The small design and structure allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth action between worm and the teeth. This increases the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with various other types of gearing.
The utilization 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 box which consists of a worm pinion input, an output worm equipment, and features a right angle result orientation. This type of reduction gear container is normally used to have a rated motor swiftness and create a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of acceleration reducer because they offer the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical testing equipment, elevators, protection 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 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 these options are produced with tough compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow output shaft and feature an adjustable mounting placement. Both the 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 quickness reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electric electric motor drives. You can choose to mount your NEMA engine to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the result or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft insight and shaft output. Interchangeable with many worm gear manufactures.

EP DDVM series triple-reduction worm gear rate reducers are available in ratios from 5000:1 to 175,000:1 and middle distances from 7” to 20” (larger sizes available on request). Result 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 are available in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water tools drive applications such as for example thickeners and clarifiers, which need a vertical straight 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 other process or materials handling systems where huge torques/slow 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 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 output. The indirect drive versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and program factor for the application form. Click on “Specs” above for a desk that will aid in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the assistance factor.
