worm gear speed reducer

worm gear speed reducer
One reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled compact drive. The proper angle set up of driving-to-driven machine requires a minimum of 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 slow speed requirements of many industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened surface and polished alloy metal worm develops a clean, work hardened surface area on the bronze equipment. 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 accessories from our standard products.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower amounts than are possible with standard cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the apparatus under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom quickness and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s rate 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 client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides even and quiet operation and allows for the likelihood of large quickness reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action 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 some other types of gearing.
The usage of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that use worm gearing are: conveyors, mixers and bucket elevators.

-Worm Wheel: Manufactured with Carbon alloy ALBC2, teeth are machined by precision CNC hobbing machine to sustain high impact.
A worm equipment reducer is one kind of reduction gear package which includes a worm pinion insight, an output worm gear, and includes a right angle output orientation. This type of reduction gear package is generally used to take a rated motor velocity and produce a low speed output with higher torque worth based on the reduction ratio. They often can solve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a popular type of swiftness reducer because they provide the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical tests equipment, elevators, security 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 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 of these options are manufactured with rugged compression-molded glass-fill up polyester housings for a long lasting, long lasting, light weight speed reducer that is 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 SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm acceleration reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electrical engine drives. You can decide to mount your NEMA engine to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want 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 the majority of worm gear manufactures.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, remaining or dual result shafts or a hollow bore result. 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 gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and provider factor for the application form. Click on “Specs” above for a table that will aid in determining the service element. For service elements above 1.0, multiply the required torque by the support factor.
