worm gear speed reducer

Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine requires a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient motor speeds are decreased to gradual speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service existence. The hardened ground and polished alloy steel worm develops a soft, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons from our standard products.
Fabricated Designs
If your application involves serious shock loads or possible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmission of higher horsepower amounts than are possible with regular cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the gear under all load conditions. In smaller sized sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom velocity and reversed engineered reducers for the application, be it a fresh project or a direct drop-in alternative to a competitor's quickness reducer. Fabricated steel 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 combination develops a soft, work-hardened mating surface of the bronze gear which improves with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides clean and quiet operation and permits the probability of large velocity reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 to as much as 3600:1. The compact design and structure allows worm equipment reducers to be placed in a comparatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost in comparison with various 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 type of reduction gear box which includes a worm pinion input, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear box is normally used to take a rated motor quickness and create a low speed result with higher torque worth based on the worm gear speed reducer decrease ratio. They often times can resolve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm gear reducers are also a favorite type of rate reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed decrease and high torque result multiplier, it's unsurprising that lots of power transmission systems utilize a worm equipment reducer. Some of the most common applications for worm gears are available in tuning instruments, medical screening 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 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 durable 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 the SW-1 and the SW-5, nevertheless, can withstand shock loading much better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm speed reducers. Worm equipment reducers are used for speed decrease and raising the torque for electric electric motor drives. You can decide to mount your NEMA electric motor to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the output or input shaft find our coupling section for choosing the coupling. We offer four assemblies left hands and right hand and double output shaft and shaft insight and shaft result. Interchangeable with many 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 models are 56C or 145TC flange mount with either right, remaining or dual output shafts or a hollow bore output. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They provide an effective low priced 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 mandatory torque and support factor for the application form. Click on “Specs” above for a desk that will assist in determining the service factor. For service elements above 1.0, multiply the required torque by the program factor.
Our standard 700 Series – the heart of Ever-Power acceleration reducer products – has been serving industry reliably for over 40 years. Its verified modular style has set the industry standard for overall performance and may be the most imitated item in the current worm gear velocity reducer market. But why accept a knock-off when you're able to have the original – from Ever-Power.
