One reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine takes a minimum of space. Input and output worm gear speed reducer 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 gradual 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 surface and polished alloy steel worm develops a clean, work hardened surface on the bronze equipment. Because of this worm gears use in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmission of higher horsepower amounts than are possible with regular cast iron systems. Extra heavy aspect plates connect the worm and gear shaft bearing facilitates, assuring proper 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 your application, be it a new project or a direct drop-in alternative to a competitor’s acceleration reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft height 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 style also includes a hardened, surface and polished alloy metal worm. This mixture develops a simple, 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 form of reducer provides simple and quiet operation and permits the probability of large velocity reductions. These gears can be found from share in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be positioned in a comparatively small space. Thus, high reductions in a limited package size can be achieved 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 offer users high reducing convenience of 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 box which consists of a worm pinion insight, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is generally used to take a rated motor velocity and produce a low speed result with higher torque value 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 due to the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of swiftness reducer because they offer the greatest speed decrease in the tiniest package. With a high ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical testing equipment, elevators, security 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 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 produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow result shaft and feature an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other reduction gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm quickness reducers. Worm gear reducers are used for speed reduction and increasing the torque for electrical engine drives. You can decide to mount your NEMA electric motor to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the output or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hands and double output shaft and shaft input and shaft result. Interchangeable with many 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 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 perfect for water/waste-water equipment drive applications such as for example thickeners and clarifiers, which need a vertical down shaft. Other obtainable configurations also make Ever-Power triple decrease reducers perfect for make use of on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or various other process or materials handling systems where large torques/slow speeds are needed.
These reducers are also obtainable 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, remaining or dual output 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 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 required torque and provider factor for the application. Click on “Specs” above for a desk that will assist in identifying the service factor. For service elements above 1.0, multiply the required torque by the assistance factor.
