Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle set up 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 engine speeds are decreased to gradual speed requirements of many industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened ground and polished alloy metal worm develops a clean, work hardened surface on the bronze equipment. For this reason worm gears put on in and improve with extented service while various other gears are deteriorating. 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 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 that allows the tranny of higher horsepower levels than are possible with regular cast iron units. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring correct meshing of the apparatus 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 offer custom swiftness and reversed engineered reducers for your application, be it a fresh project or a primary drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in replacement saving the client 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 combination develops a simple, work-hardened mating surface area of the bronze gear which enhances with prolonged service.
Worm gearing is a class of gear reducers that worm gear speed reducer utilizes right angle, nonintersecting shafts. This form of reducer provides easy and quiet procedure and allows for the likelihood of large velocity reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 up to 3600:1. The compact design and structure allows worm gear reducers to be placed in a relatively small space. Thus, very high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the continuous 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 capacity for relatively low cost when compared to various other types of gearing.
The utilization 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 container which consists of a worm pinion input, an output worm gear, and features a right angle result orientation. This kind of reduction gear box is generally used to have a rated motor velocity and create a low speed output with higher torque worth based on the reduction ratio. They often can solve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of swiftness reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed decrease and high torque output multiplier, it’s unsurprising that lots of 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 examining 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 are available 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 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 gear reducers offer an option of a solid or hollow output shaft and show an adjustable mounting position. Both SW-1 and the SW-5, nevertheless, can withstand shock loading better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm speed reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric electric motor drives. You can choose to mount your NEMA motor to the reducer utilizing the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures.

Description
The HDR Series worm equipment reducers are used in low to moderate horsepower applications to reduce speeds and increase torque. Worm gear reducers can be found in direct or indirect drive, direct drive models are 56C or 145TC flange attach with either right, remaining or dual output shafts or a hollow bore result. 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 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 services factor for the application form. Click on “Specs” above for a desk that will assist in identifying the service element. For service factors above 1.0, multiply the required torque by the program factor.
