worm gear speed reducer
Single reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine requires a minimum of space. Input and output 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 slow speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened ground and polished alloy metal worm develops a smooth, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with extented service while other gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard products.
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 offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are possible with standard cast iron units. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the apparatus under all load conditions. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for the application, be it a fresh project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also includes a hardened, surface and polished alloy steel worm. This combination develops a clean, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides soft and quiet procedure and allows for the likelihood of large swiftness reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The small design and structure allows worm gear 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 equipment features the continuous sliding tooth actions between worm and the teeth. This escalates the tolerance for large 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one kind of reduction gear box which contains a worm pinion input, an output worm equipment, and features a right angle output orientation. This kind of reduction gear package is normally used to have a rated motor quickness and create a low speed output with higher torque worth based on the decrease ratio. They often can resolve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of speed reducer because they provide the greatest speed decrease in the smallest package. With a high 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 typical 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 offers two sizes of worm equipment 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 produced with durable compression-molded glass-fill 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 an option of a good or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can endure shock loading much better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm swiftness reducers. Worm gear reducers are utilized for speed decrease and raising the torque for electric powered electric motor drives. You can choose to mount your NEMA motor to the reducer by using the NEMA C face flange or make use of a coupling. If you want a coupling for the result or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hands 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 swiftness reducers can be found in ratios from 5000:1 to 175,000:1 and center distances from 7” to 20” (larger sizes on request). Result 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 well suited for water/waste-water tools drive applications such as thickeners and clarifiers, which require 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 materials handling systems where large torques/gradual speeds are needed.

Description
The HDR Series worm gear reducers are used 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 install with either right, left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for make use of 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 decide on a gearbox speed reducer, you will need to determine the mandatory torque and service factor for the application form. Click on “Specifications” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the required torque by the services factor.
