worm gear speed reducer

worm gear speed reducer
One reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine requires a the least space. Input and result shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient electric motor speeds are decreased to sluggish speed requirements of several industrial machines in a single reduction.

The exclusive utilization 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 ground and polished alloy steel worm develops a clean, work hardened surface area on the bronze gear. For this reason worm gears put on in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a broad selection of model configurations, sizes, ratios, and components 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 products applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are possible with regular cast iron systems. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring appropriate meshing of the gear under all load conditions. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom acceleration 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 allow Ever-Power to match 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 produced from phosphorous bronze. Our design also includes a hardened, ground and polished alloy metal worm. This mixture develops a easy, work-hardened mating surface of the bronze gear which increases with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet operation and allows for the possibility of large acceleration reductions. These gears are available from share in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the constant sliding tooth action between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost when compared to 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.

A worm equipment reducer is one type of reduction gear package which contains a worm pinion input, an output worm equipment, and features a right angle output orientation. This kind of reduction gear container is generally used to have a rated motor speed and create a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems since the worm equipment reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of quickness reducer because they offer the greatest speed decrease in the tiniest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical tests equipment, elevators, security 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 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 produced with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading much better than other decrease gearbox designs, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm acceleration reducers. Worm gear reducers are used for speed reduction and increasing the torque for electrical electric motor drives. You can decide to mount your NEMA electric motor to the reducer utilizing the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft see our coupling section for choosing the coupling. You can expect four assemblies left hands and right hands and double output shaft and shaft input and shaft result. Interchangeable with most worm gear manufactures. See data sheet in item overview for diamensions. If you don’t see your type, please Contact Us.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive models are 56C or 145TC flange mount with either right, remaining or dual result shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low cost solution to speed decrease and increased 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 assistance factor for the application. Click on “Specs” above for a desk that will aid in determining the service element. For service factors above 1.0, multiply the required torque by the program factor.
