worm gear speed reducer

One reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient motor speeds are decreased to gradual speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened surface and polished alloy steel worm develops a simple, work hardened surface area on the bronze equipment. For this reason worm gears wear in and improve with extented service while various other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower levels than are possible with regular cast iron models. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring proper meshing of the gear under all load circumstances. In smaller sized 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 your application, be it a new project or a direct drop-in replacement for a competitor’s acceleration reducer. Fabricated metal reducers enable Ever-Power to match 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 manufactured from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy steel worm. This mixture develops a simple, 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 speed reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The small design and building allows worm equipment reducers to be placed in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth actions between worm and one’s teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with some 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 kind of reduction gear box which consists of a worm pinion input, an output worm gear, and includes a right angle result orientation. This kind of reduction gear package is normally used to take a rated motor quickness and produce a low speed result with higher torque value based on the reduction ratio. They often can solve space-saving problems because the worm equipment reducer is among the sleekest decrease gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a popular type of swiftness reducer because they provide the greatest speed decrease in the smallest package. With a high 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 common 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 provides two sizes of worm equipment reducer, the SW-1 and the SW-5 and both can be found in a range 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 of these options are manufactured 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 a choice of a solid or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also called worm gearbox or worm speed reducers. Worm gear reducers are utilized for speed reduction and raising the torque for electric engine drives. You can decide to attach your NEMA engine to the reducer by using the NEMA C encounter flange or make use of 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 hand and right hand and double result shaft and shaft input and shaft output. Interchangeable with most worm gear manufactures.

Description
The HDR Series worm equipment 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, still left or dual result shafts or a hollow bore result. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and support factor for the application. Click on “Specifications” above for a desk that will assist in determining the service aspect. For service factors above 1.0, multiply the required torque by the assistance factor.
