Solitary reduction worm gearing provides high ratio reduction with couple of 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 prolonged in either or both directions in horizontal or vertical plans adaptable to any mounting requirement. Efficient engine speeds are reduced to gradual speed requirements of many industrial machines in a single reduction.

The exclusive utilization of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service lifestyle. The hardened floor and polished alloy metal worm develops a clean, work hardened surface on the bronze gear. For this reason worm gears put on in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad collection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If your application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile tools applications) Ever-Power can offer fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower amounts than are feasible with standard cast iron models. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for the application, be it a fresh project or a primary drop-in replacement for a competitor’s swiftness reducer. Fabricated steel reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in substitute saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also includes a hardened, floor and polished alloy steel worm. This combination develops a simple, work-hardened mating surface of the bronze equipment which enhances with prolonged service.
Worm gearing is a class of equipment reducers that utilizes correct angle, nonintersecting shafts. This form of reducer provides even and quiet operation and permits the probability of large swiftness reductions. These gears are available from share in a wide selection of ratios, from only 4:1 up to 3600:1. The compact design and structure allows worm gear reducers to be positioned in a relatively small space. Thus, very high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth actions between worm and the teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of relatively low cost in comparison with some 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 kind of reduction gear container which includes a worm pinion input, an output worm gear, and features a right angle result orientation. This kind of reduction gear package is generally used to take a rated motor velocity and produce a low speed output with higher torque worth based on the decrease ratio. They often can resolve space-saving problems since the worm equipment reducer is one of 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 rate reducer because they offer the greatest speed reduction in the tiniest package. With a high ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical screening 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 can be found 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 these options are manufactured with durable compression-molded glass-fill polyester housings for a durable, 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 endure shock loading much better than other decrease gearbox designs, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm quickness reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electrical motor drives. You can choose to mount your NEMA motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the result or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hands and right hand and double result shaft and shaft insight and shaft output. Interchangeable with most 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 can be found 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 output. The indirect drive models are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They offer an effective low priced solution to speed decrease and improved torque, with higher tolerances for shock loading than helical gear reducers.
In order to decide on a gearbox speed reducer, you will need to determine the mandatory torque and program factor for the application form. Click on “Specifications” above for a desk that will aid in identifying the service factor. For service elements above 1.0, multiply the mandatory torque by the services factor.
