Solitary reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle arrangement 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 installation requirement. Efficient electric motor speeds are decreased to slow speed requirements of many industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service lifestyle. The hardened ground and polished alloy metal worm develops a simple, work hardened surface area on the bronze gear. Because of this worm gears wear in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus 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 transmission of higher horsepower levels than are possible with regular cast iron systems. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring correct meshing of the apparatus under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s speed 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 incorporates a hardened, surface and polished alloy steel worm. This mixture develops a soft, work-hardened mating surface of the bronze equipment which increases with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides smooth and quiet procedure and allows for the probability of large acceleration reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and building 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 continuous sliding tooth action between worm and the 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 some other types of gearing.
The utilization 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 gear reducer is one type of reduction gear container which includes a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear package is generally used to take a rated motor velocity and produce a low speed output with higher torque value 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 due to the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of speed reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed reduction 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 can be found in tuning instruments, medical assessment equipment, elevators, protection 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 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 durable, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow output shaft and feature an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm acceleration reducers. Worm gear reducers are utilized for speed decrease and increasing the torque for electrical electric motor drives. You can choose to attach your NEMA motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you need a coupling for the output 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 the majority of worm gear manufactures.

Ever-Power DDVM series triple-reduction worm gear quickness 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 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 mounted.
These reducers are ideal for water/waste-water apparatus drive applications such as for example thickeners and clarifiers, which need a vertical straight down shaft. Other offered configurations also make Ever-Power triple decrease reducers perfect for use on mixers, elevators, solar panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or materials handling systems where large torques/sluggish speeds are needed.
These reducers are also obtainable with a helical major 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 can be found in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore output. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low cost solution to speed decrease and increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and assistance factor for the application form. Click on “Specifications” above for a table that will aid in determining the service factor. For service factors above 1.0, multiply the required torque by the assistance factor.
