One reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are reduced to sluggish 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 provides for high efficiencies, and lengthy service life. The hardened ground and polished alloy steel worm develops a clean, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while additional gears are wearing out. EP offers 
a wide selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) EP can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower amounts than are feasible with standard cast iron devices. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can offer custom quickness and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s rate reducer. Fabricated metal reducers allow EP to complement a competitor’s footprint, centerline, and shaft elevation 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 style also includes a hardened, surface and polished alloy metal worm. This combination develops a simple, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and allows for the likelihood of large speed reductions. These gears can be found from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be placed in a comparatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear container which consists of a worm pinion insight, an output worm gear, and features a right angle output orientation. This kind of reduction gear box is normally 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 resolve space-saving problems since the worm equipment reducer is one of the sleekest reduction gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of speed reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed reduction 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 can be found in tuning instruments, medical testing equipment, elevators, protection 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 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 of these options are produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow output shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm velocity reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric powered electric motor drives. You can decide to mount 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 see our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double output shaft and shaft input and shaft output. Interchangeable with many 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 middle distances from 7” to 20” (larger sizes 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 can be found in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are perfect for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make EP triple decrease reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where large torques/sluggish speeds are needed.

Description
The HDR Series worm equipment 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 models are 56C or 145TC flange mount with either right, remaining or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will need to determine the required torque and support factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service aspect. For service elements above 1.0, multiply the mandatory torque by the support factor.
