Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled small 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 plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to slow 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 offers high efficiencies, and lengthy service lifestyle. The hardened ground and polished alloy metal worm develops a soft, work hardened surface on the bronze gear. Because of this worm gears use in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower amounts than are feasible with standard cast iron products. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for the application, be it a fresh project or a direct drop-in replacement for a competitor’s rate reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in replacement saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also includes a hardened, surface and polished alloy steel worm. This combination develops a easy, work-hardened mating surface of the bronze gear which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides clean and quiet procedure and permits the possibility of large rate reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and construction allows worm gear reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm gear 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 capacity for 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 box which includes a worm pinion input, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear container is generally used to have a rated motor acceleration and create a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of speed reducer because they provide the greatest speed reduction in the tiniest package. With a higher 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 examining equipment, elevators, protection 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 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 of these options are produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed reduction and raising the torque for electrical electric motor drives. You can choose to mount 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 output or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Ever-Power DDVM series triple-reduction worm gear speed 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 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 gear drive applications such as thickeners and clarifiers, which need a vertical straight down shaft. Other available configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or materials handling systems where huge torques/worm gear speed reducer sluggish speeds are needed.
These reducers are also offered with a helical major 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 can be found in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, remaining or dual output shafts or a hollow bore output. The indirect drive versions 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 decide on a gearbox speed reducer, you will have to determine the required torque and assistance factor for the application form. Click on “Specs” above for a desk that will aid in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the service factor.
