Solitary reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine requires a minimum of 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 reduced to slow speed requirements of many 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 lifestyle. The hardened ground and polished alloy metal worm develops a smooth, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with prolonged service while other gears are wearing out. EP offers a wide collection of model configurations, sizes, ratios, and accessories 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 apparatus applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are feasible with regular cast iron units. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring appropriate meshing of the gear under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with EP standard cast iron reducers.
Custom Designs
EP can provide custom speed and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s rate reducer. Fabricated steel reducers allow EP to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in EP reducers are manufactured from phosphorous bronze. Our design also includes a hardened, ground and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface of the bronze gear which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet operation and allows for the possibility of large velocity reductions. These gears can be found from stock in a wide variety 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 comparatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the constant sliding tooth actions between worm and one’s teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives provide 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 package which contains a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear box is normally used to have a rated motor velocity and create a low speed output with higher torque worth based on the reduction ratio. They often times can solve space-saving problems since the worm equipment reducer is among the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of speed reducer because they offer the greatest speed decrease in the tiniest package. With a high 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 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 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 tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm quickness reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electrical motor drives. You can choose to mount your NEMA engine 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 see our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double output shaft and shaft input and shaft result. 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). Output torque ranges from 33,000 in lbs. 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 apparatus drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make EP triple reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where huge torques/sluggish speeds are needed.
These reducers are also available with a helical primary reduction stage and are termed the HDVM series

Description
The HDR Series worm equipment reducers are used 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, left 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 provide an effective low cost solution to speed reduction and improved 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 mandatory torque and provider factor for the application form. Click on “Specs” above for a desk that will aid in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the provider factor.
