One reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine requires 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 electric motor speeds are reduced to gradual speed requirements of many industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service lifestyle. The hardened ground and polished alloy steel worm develops a clean, work hardened surface area on the bronze equipment. Because of this worm gears put on in and improve with prolonged service while other gears are wearing out. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower amounts than are possible with standard cast iron units. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom velocity 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 enable Ever-Power to complement a competitor’s footprint, centerline, and shaft height allowing a primary drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy metal worm. This combination develops a easy, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides easy and quiet procedure and permits the likelihood of large velocity reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and construction allows worm equipment reducers to be placed in a relatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost when compared to some other types of gearing.
The usage 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 package which consists of a worm pinion insight, an output worm equipment, and features a right angle output orientation. This kind of reduction gear box is normally used to take a rated motor velocity and create a low speed result with higher torque worth based on the reduction ratio. They often can solve space-saving problems since the worm gear reducer is one of the sleekest decrease gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of swiftness reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment 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 gear reducer, the SW-1 and the SW-5 and both can be found in a variety 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 durable compression-molded glass-fill up 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 an option of a good or hollow output shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed reduction and increasing the torque for electrical electric motor drives. You can choose to mount your NEMA motor to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft see our coupling section for selecting a coupling. We offer four assemblies left hand and right hands and double output shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear quickness reducers are available 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 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 installed.
These reducers are ideal for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which require a vertical straight down shaft. Other obtainable configurations also make Ever-Power triple reduction 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/sluggish speeds are needed.
These reducers are also offered with a helical main reduction stage and so are termed the HDVM series

Description
The HDR Series worm gear reducers are used 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 mount with either right, remaining or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output 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 select a gearbox speed reducer, you will need to determine the required torque and service factor for the application. Click on “Specifications” above for a desk that will assist in determining the service aspect. For service elements above 1.0, multiply the required torque by the service factor.
Our standard 700 Series – the heart of Ever-Power quickness reducer product line – has been serving industry reliably for over 40 years. Its tested modular style has set the market standard for performance and may be the most imitated product in today’s worm gear speed reducer market. But why settle for a knock-off when you can have the original – from Ever-Power.
