Solitary reduction worm gearing offers high ratio reduction with few moving 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 prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are reduced to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive use 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 floor and polished alloy metal worm develops a soft, work hardened surface on the bronze equipment. For this reason worm gears use in and improve with prolonged service while other gears are wearing out. EP offers a wide collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile tools 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 levels than are possible with regular cast iron products. Extra heavy aspect plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sizes, fabricated metal 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 fresh project or a direct drop-in alternative to a competitor’s velocity reducer. Fabricated steel reducers enable EP to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute 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, floor and polished alloy metal worm. This combination develops a easy, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides even and quiet procedure and permits the possibility of large speed reductions. These gears are available from stock in a wide variety 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 relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This escalates 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 type of reduction gear container which contains a worm pinion input, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear box is normally used to have a rated motor rate and produce a low speed output with higher torque value based on the reduction ratio. They often can resolve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of quickness reducer because they offer the greatest speed decrease in the tiniest package. With a higher ratio of speed reduction and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical tests 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 are available 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 manufactured with rugged 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 a choice of a good or hollow output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm rate reducers. Worm gear reducers are used for speed reduction and increasing the torque for electric powered motor drives. You can choose to attach your NEMA electric motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you want a coupling for the result or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double result shaft and shaft insight and shaft output. Interchangeable with most worm gear manufactures.

EP DDVM series triple-reduction worm gear swiftness 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 lbs 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 installed.
These reducers are well suited for water/waste-water devices drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other available 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/gradual 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 versions are 56C or 145TC flange install with either right, remaining or dual output shafts or a hollow bore result. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed reduction and improved 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 program factor for the application form. Click on “Specs” above for a table that will aid in identifying the service factor. For service factors above 1.0, multiply the required torque by the provider factor.
