Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are decreased to slower speed requirements of several industrial machines in a single reduction.

The exclusive use 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 steel worm develops a easy, work hardened surface on the bronze gear. For this reason worm gears use in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves serious 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 a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower levels than are possible with regular cast iron units. Extra heavy part plates connect the worm and gear shaft bearing facilitates, assuring appropriate meshing of the apparatus under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom speed and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft elevation 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 includes a hardened, floor and polished alloy metal worm. This combination develops a smooth, work-hardened mating surface area of the bronze equipment which enhances with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and permits the probability of large swiftness reductions. These gears are available from stock 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 positioned in a relatively small space. Thus, high reductions in a limited package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost when compared to 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 kind of reduction gear container which consists of a worm pinion insight, an output worm gear, and features a right angle output orientation. This kind of reduction gear container is generally used to take a rated motor speed and create a low speed result with higher torque worth based on the decrease ratio. They often times can solve space-saving problems since the worm equipment reducer is one of the sleekest decrease gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of speed reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical assessment 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 manufactured with tough compression-molded glass-fill 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 a choice of a good or hollow output shaft and show an adjustable mounting position. Both the SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm rate reducers. Worm gear reducers are used for speed reduction and raising the torque for electrical motor drives. You can decide to install your NEMA electric motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft find our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft input and shaft result. Interchangeable with the majority of worm gear manufactures.

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 available 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 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 installed.
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 reduction reducers perfect for make use of on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/gradual speeds are needed.
These reducers are also offered with a helical primary reduction stage and so are termed the HDVM series

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange mount with either right, left or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed decrease and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will need to determine the mandatory torque and provider factor for the application form. Click on “Specs” above for a table that will assist in identifying the service factor. For service factors above 1.0, multiply the required torque by the program factor.
Our standard 700 Series – the heart of Ever-Power rate reducer product line – has been serving industry reliably for over 40 years. Its tested modular design has set the sector standard for functionality and is the most imitated item in today’s worm gear speed reducer market. But why accept a knock-off when you can have the original – from Ever-Power.
