worm gear speed reducer

Single reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled compact drive. The right angle set up of driving-to-driven machine takes a the least space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to slower speed requirements of several industrial machines in one reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service life. The hardened surface and polished alloy metal worm develops a smooth, 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 collection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower amounts than are possible with regular cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring correct meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for the application, be it a new project or a primary drop-in alternative to a competitor’s speed reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary 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 incorporates a hardened, surface and polished alloy metal worm. This mixture develops a simple, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides smooth and quiet operation and allows for the likelihood of large rate reductions. These gears can be found from stock in a wide selection of ratios, from as low as 4:1 up to 3600:1. The small design and building allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the constant sliding tooth actions between worm and one’s teeth. This increases the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with 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 type of reduction gear box which contains a worm pinion input, an output worm gear, and includes a right angle output orientation. This type of reduction gear box is generally used to have a rated motor acceleration and produce a low speed result with higher torque worth based on the reduction ratio. They often times can solve space-saving problems since the worm equipment 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 speed reducer because they provide the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical tests equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers 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 rugged compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a good or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, however, can endure shock loading much better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric powered engine drives. You can decide to install your NEMA engine to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft see our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with many 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 lbs. for the 7” CD DDVM-70 to 582,900 in pounds 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 installed.
These reducers are perfect for water/waste-water devices drive applications such as thickeners and clarifiers, which require a vertical down shaft. Other available configurations also make Ever-Power triple reduction reducers perfect for use on mixers, elevators, solar power panels, astronomical telescopes, indexing tables, hoists, conveyors, or additional process or components handling systems where huge torques/slow speeds are needed.
These reducers are also available with a helical primary 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 reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, 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 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 provider factor for the application. Click on “Specifications” above for a table that will aid in identifying the service aspect. For service elements above 1.0, multiply the required torque by the assistance factor.
