Single reduction worm gearing provides high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient engine speeds are decreased to gradual speed requirements of several industrial machines in one 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 life. The hardened ground and polished alloy steel worm develops a smooth, work hardened surface on the bronze equipment. Because of this worm gears wear in and improve with prolonged service while various other gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower levels than are possible with standard cast iron units. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular 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 primary drop-in replacement for a competitor’s velocity reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, surface and polished alloy steel worm. This mixture develops a clean, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and allows for the probability of large speed reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be placed in a comparatively small space. Thus, very high reductions in a restricted 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 weighty 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 usage 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 includes a worm pinion input, an output worm equipment, and features a right angle output orientation. This kind of reduction gear box is generally used to have a rated motor acceleration and create a low speed result with higher torque worth based on the decrease ratio. They often can solve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of rate reducer because they offer the greatest speed decrease in the tiniest 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 gear reducer. Some of the most common 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 provides two sizes of worm gear reducer, the SW-1 and the SW-5 and both are available 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 of these options are produced with durable compression-molded glass-fill up polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, 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, however, can endure shock loading much better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm swiftness reducers. Worm gear reducers are used for speed reduction and increasing the torque for electric powered motor drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you need a coupling for the result or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double output shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear acceleration 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). Output torque ranges from 33,000 in lbs. 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 are available in four configurations: horizontal, vertical, shafted, and shaft installed.
These reducers are ideal for water/waste-water devices drive applications such as thickeners and clarifiers, which need a vertical down shaft. Other offered configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional 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 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 result. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and assistance factor for the application form. Click on “Specs” above for a desk that will assist in determining the service aspect. For service factors above 1.0, multiply the required torque by the service factor.
Our standard 700 Series – the heart of Ever-Power quickness reducer products – has been serving industry reliably for over 40 years. Its confirmed modular style has set the sector standard for overall performance and may be the most imitated product in the current worm gear speed reducer market. But why settle for a knock-off when you can have the initial – from Ever-Power.
