Single worm gear speed reducer reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled small drive. The proper angle set up 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 arrangements adaptable to any installation requirement. Efficient motor 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 departing side contact) on the worm and gear offers high efficiencies, and lengthy service life. The hardened floor and polished alloy metal worm develops a simple, work hardened surface area on the bronze gear. For this reason worm gears use in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile devices applications) Ever-Power can provide fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher horsepower levels than are feasible with regular cast iron products. Extra heavy part plates connect the worm and gear shaft bearing supports, assuring proper meshing of the apparatus under all load circumstances. In smaller sized sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom quickness and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s velocity reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute saving the customer 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 metal worm. This combination develops a simple, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides even and quiet operation and allows for the possibility of large swiftness reductions. These gears can be found from stock in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm gear reducers to be positioned in a comparatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the constant 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 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 kind of reduction gear container which contains a worm pinion input, an output worm gear, and features a right angle output orientation. This type of reduction gear package is generally used to have a rated motor quickness and create a low speed output with higher torque value based on the decrease ratio. They often can resolve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of speed 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 utilize a worm gear 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 equipment 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 polyester housings for a durable, long lasting, light-weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer a choice of a solid or hollow result shaft and show an adjustable mounting position. Both SW-1 and the SW-5, however, can endure shock loading much better than other reduction gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are utilized for speed decrease and raising the torque for electric powered motor drives. You can decide to install your NEMA electric motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double output shaft and shaft input and shaft output. Interchangeable with the majority of worm gear manufactures. See data sheet in product overview for diamensions. If you don’t see your type, make sure you Contact Us.

Description
The HDR Series worm equipment 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 versions are 56C or 145TC flange install with either right, still left or dual result shafts or a hollow bore output. 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 increased torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on 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 determining the service element. For service factors above 1.0, multiply the mandatory torque by the program factor.
