Solitary reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine takes 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 motor speeds are decreased to slower 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 lengthy service lifestyle. The hardened floor and polished alloy metal worm develops a simple, work hardened surface area on the bronze gear. For this reason worm gears use in and improve with prolonged service while various other gears are deteriorating. EP offers a wide selection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) EP can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are feasible with standard cast iron products. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the gear 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 speed and reversed engineered reducers for the application, be it a fresh project or a primary drop-in alternative to a competitor’s quickness reducer. Fabricated steel reducers enable EP to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct 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 includes a hardened, surface and polished alloy metal worm. This mixture develops a easy, work-hardened mating surface of the bronze gear which enhances with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and permits the possibility of large rate reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm gear reducers to be positioned in a relatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This increases the tolerance for large 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 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 gear reducer is one kind of reduction gear container which consists of a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear container is generally used to take a rated motor rate and produce a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems since the worm gear reducer is one of the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of acceleration reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm gear reducer, the SW-1 and the SW-5 and both can be found 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 durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand 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 swiftness reducers. Worm equipment reducers are utilized for speed decrease 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 result or input shaft observe our coupling section for selecting a coupling. You can expect four assemblies left hands 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 speed 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water gear drive applications such as thickeners and clarifiers, which require a vertical straight down shaft. Other offered configurations also make EP triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components 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 lessen speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive models are 56C or 145TC flange install with either right, still left or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced 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 mandatory torque and support factor for the application. Click on “Specs” above for a table that will aid in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the service factor.
