worm gear speed reducer

One reduction worm gearing provides high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle set up of driving-to-driven machine requires a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are reduced to slower speed requirements of many industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service life. The hardened surface and polished alloy metal worm develops a soft, work hardened surface on the bronze equipment. For this reason worm gears put on in and improve with extented service while additional gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves serious shock loads or possible 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 which allows the tranny of higher horsepower amounts than are feasible with regular cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom rate and reversed engineered reducers for the application, be it a new project or a direct drop-in replacement for a competitor’s velocity reducer. Fabricated metal reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, floor and polished alloy metal worm. This mixture develops a clean, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides even and quiet operation and permits the likelihood of large velocity reductions. These gears can be found from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and structure allows worm gear 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 equipment features the continuous sliding tooth actions between worm and one’s teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing capacity for 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 gear reducer is one type of reduction gear container which consists of a worm pinion insight, an output worm equipment, and features a right angle output orientation. This kind of reduction gear box is generally used to have a rated motor acceleration and produce a low speed result with higher torque value based on the reduction ratio. They often times can resolve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of rate reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical assessment 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 produced with rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, however, can endure shock loading better than other decrease gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm rate reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric powered engine drives. You can decide to mount your NEMA 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 find our coupling section for selecting a coupling. You can expect four assemblies left hands and right hands and double result shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures. See data sheet in item overview for diamensions. If you don’t see your type, please worm gear speed reducer contact Us.

Ever-Power DDVM series triple-reduction worm gear speed reducers are available 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 installed.
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 power panels, astronomical telescopes, indexing tables, hoists, conveyors, or other process or components handling systems where large torques/slower speeds are needed.

Description
The HDR Series worm equipment 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, remaining or dual output shafts or a hollow bore result. The indirect drive models 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 gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and service factor for the application. Click on “Specs” above for a desk that will assist in determining the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
