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 right angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are decreased to slow speed requirements of several industrial machines in a single 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 ground and polished alloy steel worm develops a simple, work hardened surface area on the bronze gear. For this reason worm gears put on in and improve with extented service while various other gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and accessories from our standard product line.
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 offer fabricated steel housings with up to 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 products. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom velocity and reversed engineered reducers for your application, be it a fresh project or a direct drop-in replacement for a competitor’s quickness reducer. Fabricated metal reducers enable Ever-Power to complement 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 produced from phosphorous bronze. Our design also includes a hardened, surface and polished alloy steel worm. This mixture develops a even, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a course of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides clean and quiet procedure and allows for the possibility of large rate reductions. These gears are available from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and construction allows worm gear reducers to be positioned in a comparatively small space. Thus, 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 heavy loads and shock loads. Worm gear drives provide users high reducing capacity for 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 includes a worm pinion input, an output worm gear, and features a right angle output orientation. This type of reduction gear container is generally used to have a rated motor quickness and create a low speed output with higher torque value based on the reduction ratio. They often times can resolve space-saving problems since the worm gear reducer is one of the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of swiftness reducer because they offer the greatest speed decrease in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment reducer. Some of the most common applications for worm gears can be found in tuning instruments, medical tests equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm gear 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 produced with durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow output shaft and feature 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 perfect for demanding applications.

Worm Equipment Reducers also called worm gearbox or worm swiftness reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric powered electric motor drives. You can choose to attach your NEMA electric motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft find our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double output shaft and shaft input and shaft result. Interchangeable with many worm gear manufactures.

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 models are 56C or 145TC flange attach with either right, still left or dual result shafts or a hollow bore output. 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 improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to select a gearbox speed reducer, you will have to determine the required torque and provider factor for the application form. Click on “Specifications” above for a desk that will aid in identifying the service aspect. For service elements above 1.0, multiply the required torque by the program factor.
