Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine requires a the least space. Input and result worm gear speed reducer 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 gradual speed requirements of many 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 lifestyle. The hardened floor and polished alloy steel worm develops a even, work hardened surface area on the bronze gear. Because of this worm gears use in and improve with prolonged service while other gears are deteriorating. 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 serious shock loads or possible 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 optimum rigidity and strength which allows the transmitting of higher horsepower amounts than are feasible with standard cast iron units. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the gear 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 acceleration and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s velocity reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also includes a hardened, surface and polished alloy metal worm. This mixture develops a smooth, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet operation and allows for the possibility of large rate 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 structure allows worm equipment reducers to be placed in a comparatively small space. Thus, high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth actions between worm and the teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing capacity for 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which consists of a worm pinion insight, an output worm gear, and features a right angle output orientation. This type of reduction gear package is generally used to have a rated motor speed and create a low speed result with higher torque value based on the reduction ratio. They often times can solve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available because of the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a favorite type of quickness reducer because they offer the greatest speed reduction 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 gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical testing equipment, elevators, protection 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 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 produced with rugged compression-molded glass-fill up 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 position. Both SW-1 and the SW-5, nevertheless, can endure shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are utilized for speed decrease and increasing the torque for electrical motor drives. You can decide to attach 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 result or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hands and double output shaft and shaft input and shaft result. 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). Output torque ranges from 33,000 in lbs. 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 are available in four configurations: horizontal, vertical, shafted, and shaft mounted.
These reducers are ideal for water/waste-water devices drive applications such as for example thickeners and clarifiers, which require a vertical down shaft. Other offered 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 components handling systems where huge torques/gradual speeds are needed.
These reducers are also offered with a helical principal reduction stage and so are termed the HDVM series

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 mount with either right, still left or dual result shafts or a hollow bore output. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low priced 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 mandatory torque and service factor for the application form. Click on “Specs” above for a desk that will aid in determining the service aspect. For service elements above 1.0, multiply the mandatory torque by the service factor.
