worm gear speed reducer
One reduction worm gearing offers 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 output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient engine speeds are decreased to gradual speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service life. The hardened surface and polished alloy metal worm develops a clean, work hardened surface area on the bronze equipment. For this reason worm gears use in and improve with extented service while additional gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and accessories 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 gear applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with regular cast iron devices. Extra heavy part plates connect the worm and equipment 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 provide custom swiftness and reversed engineered reducers for the application, be it a new project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also includes a hardened, surface and polished alloy steel worm. This combination develops a easy, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides even and quiet operation and permits the likelihood of large velocity reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The small design and structure 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 one’s teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear box which includes a worm pinion input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear package is normally used to have a rated motor acceleration and produce a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of rate reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical examining 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 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 tough compression-molded glass-fill up 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 an option of a good or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox designs, 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 electric powered engine drives. You can decide to mount your NEMA engine to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hands and right hand and double output shaft and shaft insight and shaft output. Interchangeable with most worm gear manufactures.

Ever-Power 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 available on request). Result 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 perfect for water/waste-water tools drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable 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 large torques/slower 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 are available in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, remaining or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft result 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 gear reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and services factor for the application. Click on “Specifications” above for a table that will aid in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the provider factor.
