worm gear speed reducer

Solitary reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled compact drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and result 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 gradual speed requirements of many industrial machines in one 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 metal worm develops a smooth, work hardened surface on the bronze gear. For this reason worm gears use in and improve with extented service while various other gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves serious 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 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 facilitates, assuring proper meshing of the gear under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom velocity and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s rate reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary drop-in replacement saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, ground and polished alloy steel worm. This combination develops a simple, work-hardened mating surface of the bronze gear which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet operation and allows for the probability of large acceleration reductions. These gears are available from stock in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm equipment reducers to be placed in a relatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and the teeth. This escalates the tolerance for weighty 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 use of worm gearing extends across many industries including food, beverage and grain and has many applications. Some applications that make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear package which includes a worm pinion insight, an output worm gear, and features a right angle result orientation. This kind of reduction gear container is generally used to have a rated motor rate and create a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems because the worm gear reducer is one of the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of velocity reducer because they provide the greatest speed reduction in the smallest 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 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 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 long lasting, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a solid or hollow result shaft and feature an adjustable mounting position. Both the SW-1 and the SW-5, nevertheless, can endure shock loading much better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm quickness reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric powered motor drives. You can choose to install your NEMA motor to the reducer by using the NEMA C encounter flange or use a coupling. If you want a coupling for the result or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double result shaft and shaft input and shaft output. Interchangeable with the majority of 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 install with either right, left or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of with sprocket or pulley drive systems. They offer an effective low priced solution to speed reduction 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 mandatory torque and assistance factor for the application form. Click on “Specifications” 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.
