worm gear speed reducer
Solitary reduction worm gearing provides 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 the least space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any mounting requirement. Efficient motor speeds are decreased to sluggish speed requirements of many industrial machines in a single 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 floor and polished alloy metal worm develops a even, work hardened surface area on the bronze equipment. Because of this worm gears use in and improve with prolonged service while other gears are wearing out. Ever-Power offers a broad selection 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 maximum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with regular cast iron devices. Extra heavy aspect plates connect the worm and gear shaft bearing supports, assuring correct 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 provide custom rate and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s quickness reducer. Fabricated metal reducers allow Ever-Power to match a competitor’s footprint, centerline, and shaft height allowing a direct drop-in alternative saving the client time and money.
Long – Quiet Life
All worm gears in Ever-Power reducers are produced from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy metal worm. This combination develops a easy, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a class of gear reducers that utilizes correct angle, nonintersecting shafts. This style of reducer provides simple and quiet procedure and allows for the likelihood of large velocity reductions. These gears are available from stock in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and building allows worm equipment reducers to be positioned in a relatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for large 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 make use of worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear package which contains a worm pinion input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is generally used to take a rated motor swiftness and create a low speed output with higher torque worth based on the reduction ratio. They often times can solve space-saving problems because the worm equipment reducer is one of the sleekest decrease gearboxes available because of the little diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of quickness reducer because they provide the greatest speed decrease in the smallest package. With a high ratio of speed decrease and high torque result multiplier, it’s unsurprising that lots of 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 testing 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 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 these options are produced with tough 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 good or hollow result shaft and show an adjustable mounting placement. Both SW-1 and the SW-5, however, can endure shock loading better than other reduction gearbox styles, making them perfect for demanding applications.

Worm Equipment Reducers also referred to as worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed reduction and increasing the torque for electric motor drives. You can choose to install your NEMA motor to the reducer utilizing the NEMA C face flange or make use of a coupling. If you want a coupling for the result or input shaft discover our coupling section for choosing the coupling. You can expect four assemblies left hands and right hand and double result shaft and shaft input 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 are available in direct or indirect drive, direct drive models are 56C or 145TC flange install with either right, still 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 cost solution to speed decrease and increased 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 assistance factor for the application form. Click on “Specifications” above for a desk that will assist in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
