One reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient electric motor speeds are decreased to sluggish speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service life. The hardened surface and polished alloy metal worm develops a simple, work hardened surface on the bronze gear. For this reason worm gears use in and improve with prolonged service while additional gears are wearing out. EP offers a broad collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) EP can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower amounts than are possible with regular cast iron units. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring correct meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with EP regular cast iron reducers.
Custom Designs
EP can provide custom speed and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s acceleration reducer. Fabricated steel reducers enable EP to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in EP reducers are produced from phosphorous bronze. Our style also incorporates a hardened, surface and polished alloy metal worm. This combination develops a soft, work-hardened mating surface area of the bronze gear which increases 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 operation and allows for the probability of large rate reductions. These gears can be found from stock in a wide selection of ratios, from only 4:1 to as much as 3600:1. The small design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and one’s 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 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.
EP worm equipment reducer gearbox series base on years of experiences uses designed teeth surface area with unsurpassed torque transfer performance with great performance, efficency and cost.Worm gear system transmits power through sliding contact, resulting in extremely low vibration , sound, little backlash and self-locking property
-Housing:Onetime we casting creats great rigidity for serious impacts. Outer cooling fins and internal lubrication oil diversion channel style to increase heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Steel S45C or SCM415, precison machined and carburized to HRC45 or HRC60, after that for precision tooth grinding to make sure maximum contacting.
-Worm Wheel: Manufactured with Carbon alloy ALBC2, teeth are machined by precision CNC hobbing machine to sustain high impact.
A worm gear reducer is one kind of reduction gear box which consists of a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear package is normally used to take a rated motor swiftness and produce a low speed output with higher torque value based on the decrease ratio. They often can resolve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of quickness reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment reducer. Some of the most typical applications for worm gears are available 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 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 manufactured with durable compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading much better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm swiftness reducers. Worm gear reducers are utilized for speed reduction and raising the torque for electric powered engine drives. You can decide to attach your NEMA electric motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you need a coupling for the output or input shaft see our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double output shaft and shaft input and shaft result. Interchangeable with the majority of 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 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 insight 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 for example thickeners and clarifiers, which require a vertical straight down shaft. Other available configurations also make EP triple reduction 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/slow speeds are needed.
These reducers are also available with a helical principal reduction stage and so are termed the HDVM series

Description
The HDR Series worm equipment reducers are found 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, still left or dual output 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 provide an effective low cost solution to speed decrease 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 mandatory torque and program factor for the application form. Click on “Specs” above for a desk that will aid in determining the service element. For service elements above 1.0, multiply the required torque by the provider factor.
