Single reduction worm gearing offers high ratio reduction with couple of shifting parts in a close-coupled small drive. The right angle arrangement of driving-to-driven machine requires 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 gradual speed requirements of several industrial machines in one reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear provides for high efficiencies, and lengthy service life. The hardened floor and polished alloy steel worm develops a easy, work hardened surface on the bronze equipment. 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 product line.
Fabricated Designs
If the application involves serious shock loads or feasible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength which allows the tranny of higher worm gear speed reducer horsepower amounts than are feasible with regular cast iron devices. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring appropriate meshing of the gear under all load conditions. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom rate and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s velocity reducer. Fabricated metal reducers enable Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a primary drop-in alternative saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our style also incorporates a hardened, floor and polished alloy steel worm. This combination develops a soft, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet operation and allows for the possibility of large acceleration reductions. These gears can be found from share in a wide selection of ratios, from only 4:1 up to 3600:1. The small design and construction allows worm gear reducers to be placed in a comparatively small space. Thus, 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 one’s teeth. This escalates the tolerance for heavy loads and shock loads. Worm gear drives offer users high reducing capacity for relatively low cost in comparison with various 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 equipment, and features a right angle output orientation. This kind of reduction gear box is normally used to take a rated motor rate and create a low speed result with higher torque worth based on the decrease ratio. They often times can resolve space-saving problems because the worm equipment reducer is one of the sleekest reduction gearboxes available due to the small diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of velocity reducer because they offer the greatest speed decrease in the smallest package. With a high ratio of speed reduction and high torque result multiplier, it’s unsurprising that many power transmission systems make use of a worm gear reducer. Some of the most common applications for worm gears are available in tuning instruments, medical examining 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 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 up polyester housings for a long lasting, long lasting, light-weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow output shaft and show an adjustable mounting placement. Both the SW-1 and the SW-5, nevertheless, can endure shock loading better than other reduction gearbox styles, making them ideal for demanding applications.

Worm Gear Reducers also called worm gearbox or worm rate 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 face flange or make use of a coupling. If you need a coupling for the output 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 input and shaft output. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm equipment 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 mount with either right, left or dual output shafts or a hollow bore result. 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 select a gearbox speed reducer, you will have to determine the mandatory torque and program factor for the application. Click on “Specs” above for a desk that will aid in determining the service element. For service elements above 1.0, multiply the mandatory torque by the program factor.
