Single reduction worm gearing provides high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle arrangement of driving-to-driven machine takes a the least space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are reduced to sluggish speed requirements of several industrial machines in one reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened surface and polished alloy metal worm develops a soft, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with extented service while various other gears are wearing out. Ever-Power offers a wide selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can offer fabricated steel housings with up to a 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 products. Extra heavy side plates connect the worm and equipment shaft bearing facilitates, assuring proper 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 velocity and reversed engineered reducers for the application, be it a new project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also includes a hardened, floor and polished alloy metal worm. This combination develops a soft, work-hardened mating surface of the bronze equipment which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides easy and quiet procedure and permits the probability of large speed 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 small design and building allows worm gear reducers to be positioned in a relatively small space. Thus, very 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 provide users high reducing convenience of relatively low cost in comparison with some 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm gear reducer is one kind of reduction gear container which contains a worm pinion input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear box is normally used to take a rated motor swiftness and create a low speed output with higher torque worth based on the decrease ratio. They often can resolve space-saving problems since the worm gear reducer is one of the sleekest decrease gearboxes available due to the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a favorite type of acceleration reducer because they offer the greatest speed decrease in the smallest 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 assessment 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 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 manufactured with durable compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that’s also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a good or hollow result shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm velocity reducers. Worm gear reducers are used for speed reduction and raising the torque for electric electric motor drives. You can decide to mount 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 see our coupling section for selecting a coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft insight and shaft output. Interchangeable with many worm gear manufactures. Observe 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 used in low to moderate horsepower applications to lessen speeds and increase torque. Worm gear reducers are available in direct or indirect drive, direct drive versions are 56C or 145TC flange install with either right, remaining or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They offer an effective low cost solution to speed reduction and increased torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the required torque and program factor for the application. Click on “Specifications” above for a table that will assist in identifying the service element. For service factors above 1.0, multiply the required torque by the program factor.
