worm gear speed reducer
Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine requires a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are reduced to gradual 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 lengthy service life. The hardened ground and polished alloy metal worm develops a easy, work hardened surface on the bronze equipment. For this reason worm gears put on in and improve with prolonged service while other 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 offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower levels than are possible with regular cast iron units. Extra heavy part plates connect the worm and equipment shaft bearing facilitates, assuring correct meshing of the apparatus 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 offer custom quickness 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 match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, surface and polished alloy metal worm. This mixture develops a easy, work-hardened mating surface of the bronze gear which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides easy and quiet operation and permits the possibility 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 small design and building allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a limited 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 convenience of relatively low cost when compared to various 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 gear reducer is one type of reduction gear box which consists of a worm pinion input, an output worm equipment, and includes a right angle result orientation. This kind of reduction gear container is generally used to take a rated motor quickness and produce a low speed result with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of speed reducer because they provide the greatest speed reduction in the smallest package. With a higher ratio of speed reduction 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 examining equipment, elevators, security 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 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 these options are produced with rugged compression-molded glass-fill up polyester housings for a durable, long lasting, light weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow output shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, nevertheless, can endure shock loading better than other decrease gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm swiftness reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric electric motor drives. You can decide to install your NEMA electric motor to the reducer utilizing 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 result. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm gear reducers are found in low to moderate horsepower applications to lessen 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 result. The indirect drive models 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 service factor for the application form. Click on “Specifications” above for a table that will assist in determining the service aspect. For service factors above 1.0, multiply the required torque by the assistance factor.
