worm gear speed reducer
Solitary 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 takes a minimum of space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to sluggish speed requirements of several industrial machines in a single 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 existence. The hardened floor and polished alloy steel worm develops a easy, work hardened surface area on the bronze equipment. Because of this worm gears put on in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and components 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 maximum rigidity and strength which allows the transmitting of higher horsepower amounts than are possible with regular cast iron products. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring appropriate 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 swiftness and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s swiftness reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in replacement saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy metal worm. This mixture develops a smooth, work-hardened mating surface of the bronze gear which boosts with prolonged service.
Worm gearing is a class of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides even and quiet operation and permits the possibility of large quickness reductions. These gears can be found from share in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be positioned in a relatively small space. Thus, 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 large loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with 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 gear reducer is one type of reduction gear package which contains a worm pinion insight, an output worm gear, and features a right angle result orientation. This kind of reduction gear container is generally used to have a rated motor quickness and produce a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems because the worm gear 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 offer the greatest speed reduction in the smallest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical testing equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm equipment 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 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, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow output shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm acceleration reducers. Worm gear reducers are utilized for speed decrease and raising the torque for electric engine drives. You can decide to install your NEMA electric motor to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft find our coupling section for selecting a coupling. We offer four assemblies left hands and right hand 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 rate 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). Result torque ranges from 33,000 in lbs. for the 7” CD DDVM-70 to 582,900 in lbs 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 perfect for water/waste-water apparatus 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 various other process or materials handling systems where huge torques/slower 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 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 versions are 56C or 145TC flange mount with either right, left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction 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 services factor for the application form. Click on “Specs” above for a desk that will assist in determining the service aspect. For service elements above 1.0, multiply the required torque by the program factor.
