One reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient electric motor speeds are decreased to slower speed requirements of many industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened ground and polished alloy metal worm develops a simple, work hardened surface area on the bronze gear. Because of this worm gears put on in and improve with extented service while other gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are feasible with standard cast iron systems. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom speed and reversed engineered reducers for your application, be it a new project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also includes a hardened, ground and polished alloy metal worm. This mixture develops a easy, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and allows for the possibility of large rate reductions. These gears are available from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm equipment reducers to be placed in a comparatively small space. Thus, very 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 the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing convenience of 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.

A worm equipment reducer is one type of reduction gear package which contains a worm pinion worm gear speed reducer insight, an output worm gear, and includes a right angle result orientation. This type of reduction gear container is generally used to have a rated motor velocity and create a low speed output with higher torque value based on the reduction ratio. They often times can solve space-saving problems since the worm gear 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 swiftness reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear 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 offers two sizes of worm equipment 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 produced with durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electrical electric motor drives. You can decide to attach your NEMA engine to the reducer utilizing the NEMA C encounter flange or use 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 hands and right hands and double output shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures. Observe data sheet in item overview for diamensions. If you don’t see your type, make sure you Contact Us.

Ever-Power 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). Result 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 well suited for water/waste-water devices drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where huge torques/slower speeds are needed.

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 install with either right, still left or dual result shafts or a hollow bore output. The indirect drive versions are shaft input-shaft output boxes for make use of 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 decide on a gearbox speed reducer, you will need to determine the required torque and assistance factor for the application form. Click on “Specifications” above for a table that will aid in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the support factor.
