One reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The right angle set up of driving-to-driven machine requires a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient engine speeds are reduced to sluggish 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 lifestyle. The hardened ground and polished alloy steel worm develops a clean, work hardened surface on the bronze equipment. For this reason worm gears use in and improve with extented service while other gears are wearing out. 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 possible housing damage from external sources (as in steel mills or mobile apparatus applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower amounts than are possible with regular cast iron units. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can offer custom swiftness and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor’s swiftness reducer. Fabricated metal reducers allow EP to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our design also includes a hardened, floor and polished alloy steel worm. This combination develops a clean, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet operation and allows for the possibility of large swiftness reductions. These gears are available from share in a wide selection of ratios, from only 4:1 to as much as 3600:1. The small design and building allows worm gear reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth actions between worm and the teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives provide users high reducing capacity for 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 container which contains a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear package is generally used to have a rated motor rate and create a low speed result with higher torque worth based on the decrease ratio. They often can resolve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of swiftness 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 make use of a worm equipment reducer. Some of the most common 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 of these options are produced with rugged compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow result shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric powered electric motor drives. You can choose to mount your NEMA electric motor 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 find our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double output shaft and shaft insight and shaft output. Interchangeable with many worm gear manufactures.

EP DDVM series triple-reduction worm gear rate reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Output torque ranges from 33,000 in lbs. 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 perfect for water/waste-water tools drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable configurations also make EP triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where large torques/slower speeds are needed.
These reducers are also obtainable with a helical principal 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 can be found in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, remaining or dual output shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They provide an effective low cost 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 services factor for the application form. Click on “Specifications” above for a table that will aid in identifying the service element. For service elements above 1.0, multiply the required torque by the provider factor.
