Solitary reduction worm gearing offers high ratio reduction with couple of moving parts in a close-coupled small drive. The proper angle set up of driving-to-driven machine takes a minimum of space. Input and result shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are decreased 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 provides for high efficiencies, and lengthy service life. The hardened ground and polished alloy steel worm develops a easy, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with prolonged service while additional gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and add-ons 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 apparatus applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide maximum rigidity and strength which allows the transmitting of higher horsepower amounts than are possible with regular cast iron systems. Extra heavy side plates connect the worm and gear shaft bearing facilitates, assuring proper meshing of the apparatus under all load circumstances. In smaller sizes, fabricated steel reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can offer custom rate 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 enable Ever-Power to match a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in replacement saving the customer time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are manufactured from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy steel worm. This combination develops a easy, work-hardened mating surface of the bronze equipment which increases with prolonged service.
Worm gearing is a class of gear reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides soft and quiet procedure and allows for the possibility of large speed reductions. These gears are available from share in a wide variety of ratios, from only 4:1 up to 3600:1. The compact design and building allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a limited 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 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 kind of reduction gear box which consists of a worm pinion insight, an output worm equipment, and includes a right angle output orientation. This kind of reduction gear package is normally used to take a rated motor rate and create a low speed output with higher torque worth based on the reduction ratio. They often can solve space-saving problems because the worm gear reducer is one of the sleekest decrease gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of velocity reducer because they offer the greatest speed reduction in the tiniest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that many 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 tests equipment, elevators, protection gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission offers 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 of these options are produced with rugged compression-molded glass-fill polyester housings for a long lasting, long lasting, light weight speed reducer that is also compact, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow output shaft and show an adjustable mounting placement. Both 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 Equipment Reducers also known as worm gearbox or worm velocity reducers. Worm gear reducers are utilized for speed reduction and increasing the torque for electric powered motor drives. You can choose to install your NEMA engine to the reducer utilizing the NEMA C encounter flange or make use of a coupling. If you want a coupling for the output or input shaft observe our coupling section for selecting a coupling. We offer four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. Interchangeable with the majority of worm gear manufactures.

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 models are 56C or 145TC flange attach with either right, left or dual result shafts or a hollow bore result. The indirect drive versions are shaft input-shaft result boxes for use with sprocket or pulley drive systems. They provide an effective low priced solution to speed decrease 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 provider factor for the application form. Click on “Specs” above for a desk that will assist in determining the service aspect. For service elements above 1.0, multiply the required torque by the program factor.
