Solitary reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine requires a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are decreased to slow speed requirements of many 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 lengthy service life. The hardened floor and polished alloy steel worm develops a even, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with extented service while various other gears are deteriorating. EP offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower levels than are feasible with regular cast iron systems. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom speed and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor’s swiftness reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our style also includes a hardened, surface and polished alloy steel worm. This combination develops a soft, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides simple and quiet procedure and allows for the possibility of large speed reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm equipment reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear box which includes a worm pinion insight, an output worm equipment, and features a right angle result orientation. This kind of reduction gear container is generally used to have a rated motor quickness and create a low speed result with higher torque value based on the reduction ratio. They often can solve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of rate reducer because they offer the greatest speed decrease in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that many 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, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers two sizes of worm gear 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 produced with durable compression-molded glass-fill polyester housings for a durable, 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 position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm velocity reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric powered motor drives. You can decide to attach your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft discover our coupling section for selecting a coupling. We offer four assemblies left hand and right hands 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 can be found in ratios from 5000:1 to 175,000:1 and middle 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 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are well suited for water/waste-water gear drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make EP triple decrease reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where huge torques/slow speeds are needed.
These reducers are also available with a helical main reduction stage and so are termed the HDVM series

Description
The HDR Series worm gear 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 mount with either right, still left or dual result shafts or a hollow bore result. 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 priced 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 have to determine the mandatory torque and assistance factor for the application. Click on “Specifications” above for a table that will assist in identifying the service aspect. For service factors above 1.0, multiply the mandatory torque by the program factor.
