worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient motor speeds are reduced to slower speed requirements of many industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service lifestyle. The hardened surface and polished alloy metal worm develops a simple, work hardened surface on the bronze equipment. Because of this worm gears use in and improve with extented service while various other gears are deteriorating. EP offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) EP can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower amounts than are possible with regular cast iron devices. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring correct 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 speed and reversed engineered reducers for your application, be it a fresh project or a primary drop-in replacement for a competitor’s velocity reducer. Fabricated steel reducers allow EP to complement a competitor’s footprint, centerline, and shaft height allowing a direct 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, floor and polished alloy metal worm. This combination develops a clean, work-hardened mating surface area of the bronze gear which improves 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 procedure and allows for the probability of large quickness reductions. These gears can be found 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, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and the 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 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 use 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 input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear box 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 can solve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of velocity reducer because they provide the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most typical 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 can be found 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 long lasting, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a good or hollow output shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electrical engine drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double result 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 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 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 can be found in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are well suited for water/waste-water devices drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other available configurations also make EP triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where large torques/sluggish speeds are needed.
These reducers are also obtainable with a helical main reduction stage and 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 can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange attach with either right, still left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and support factor for the application form. Click on “Specifications” above for a table that will assist in identifying the service aspect. For service elements above 1.0, multiply the required torque by the provider factor.
