Solitary reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The proper 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 arrangements adaptable to any installation requirement. Efficient engine speeds are reduced to sluggish 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 lifestyle. The hardened ground and polished alloy metal worm develops a easy, work hardened surface on the bronze gear. Because of this worm gears wear in and improve with extented service while additional gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and components from our standard product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile apparatus applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with standard cast iron systems. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the gear under all load conditions. In smaller sizes, fabricated steel 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 new project or a direct drop-in replacement for a competitor’s swiftness reducer. Fabricated steel reducers enable Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also includes a hardened, floor and polished alloy steel worm. This combination develops a easy, work-hardened mating surface area of the bronze equipment which improves with prolonged service.
Worm gearing is a course of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides clean and quiet procedure and allows for the probability of large velocity reductions. These gears can be found from share in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm gear reducers to be positioned in a comparatively 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 large 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 usage 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 equipment reducer is one type of reduction gear container which contains a worm pinion insight, an output worm gear, and includes a right angle output orientation. This type of reduction gear container is generally used to have a rated motor rate and create a low speed output with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems since the worm gear reducer is among the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of velocity reducer because they offer the greatest speed reduction in the tiniest package. With a higher ratio of speed reduction 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, 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 are available 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 durable compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox designs, making them well suited for demanding applications.

Worm Equipment Reducers also known as worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric powered electric motor drives. You can choose to install your NEMA 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 discover our coupling section for selecting a coupling. We offer four assemblies left hands and right hands and double output shaft and shaft insight and shaft output. Interchangeable with the majority of worm gear manufactures. See data sheet in item overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm gear reducers are found 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 install with either right, left or dual output shafts or a hollow bore output. The indirect drive versions are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They provide an effective low priced solution to speed decrease and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to select a gearbox speed reducer, you will have to determine the mandatory torque and program factor for the application form. Click on “Specs” above for a table that will aid in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the service factor.
