worm gear speed reducer
One reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle arrangement 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 installation requirement. Efficient engine 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 long service existence. The hardened floor and polished alloy metal worm develops a simple, work hardened surface on the bronze gear. For this reason worm gears put on in and improve with extented service while various other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If the application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can provide 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 feasible with regular cast iron products. 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 standard cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s quickness reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also includes a hardened, ground 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 gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides soft and quiet procedure and allows for the probability of large swiftness reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and the teeth. This increases the tolerance for heavy 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.

A worm equipment reducer is one kind of reduction gear box which contains a worm pinion input, an output worm equipment, and features a right angle result orientation. This type of reduction gear container is normally used to have a rated motor quickness and create a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of speed reducer because they provide the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical assessment equipment, elevators, protection 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 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 manufactured with tough compression-molded glass-fill 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 output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric motor drives. You can choose to install 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 output or input shaft find our coupling section for selecting a coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

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). 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 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 installed.
These reducers are ideal for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other offered configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where huge torques/gradual speeds are needed.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to reduce 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 output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed decrease 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 required torque and service factor for the application. Click on “Specs” above for a table that will assist in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the program factor.
