worm gear speed reducer single reduction worm gearing offers high ratio reduction with few moving parts in a close-coupled small drive. The proper angle arrangement 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 installation requirement. Efficient motor speeds are reduced to slow speed requirements of many industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and lengthy service life. The hardened ground and polished alloy steel worm develops a even, work hardened surface on the bronze equipment. Because of this worm gears put on in and improve with prolonged service while various other gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and accessories from our standard product line.
Fabricated Designs
If your application involves severe 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 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the transmitting of higher horsepower levels than are feasible with standard cast iron models. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the gear under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can offer custom swiftness and reversed engineered reducers for your application, be it a new project or a primary drop-in alternative to a competitor’s swiftness reducer. Fabricated steel reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our style also incorporates a hardened, floor and polished alloy steel worm. This combination develops a clean, work-hardened mating surface 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 easy and quiet operation and allows for the likelihood of large velocity reductions. These gears can be found from share in a wide variety of ratios, from as low as 4:1 up to 3600:1. The compact design and construction allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm gear features the constant sliding tooth action between worm and the teeth. This increases the tolerance for weighty loads and shock loads. Worm gear drives offer users high reducing capacity for 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear package which contains a worm pinion insight, an output worm equipment, and features a right angle output orientation. This type of reduction gear box is generally used to take a rated motor acceleration and create a low speed result with higher torque worth based on the reduction ratio. They often can solve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of swiftness reducer because they offer the greatest speed reduction in the tiniest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems utilize a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical tests equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm equipment 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 rugged compression-molded glass-fill up 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 feature an adjustable mounting position. Both SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm acceleration reducers. Worm equipment reducers are used for speed decrease and raising the torque for electric powered electric motor drives. You can choose to install your NEMA engine to the reducer utilizing the NEMA C face flange or use a coupling. If you want a coupling for the result or input shaft observe our coupling section for choosing the coupling. You can expect four assemblies left hand and right hand and double result shaft and shaft input and shaft result. Interchangeable with the majority of 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 are available in direct or indirect drive, direct drive models are 56C or 145TC flange mount with either right, still left or dual output shafts or a hollow bore result. The indirect drive versions are shaft input-shaft output boxes for use with sprocket or pulley drive systems. They offer an effective low cost 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 need to determine the required torque and provider factor for the application form. Click on “Specs” above for a desk that will aid in determining the service aspect. For service factors above 1.0, multiply the mandatory torque by the service factor.
