worm gear speed reducer

Single reduction worm gearing provides 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 minimum of space. Input and output shafts can be prolonged in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient motor speeds are decreased to slower speed requirements of several industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with leaving side contact) on the worm and gear provides for high efficiencies, and long service existence. The hardened surface and polished alloy metal worm develops a easy, work hardened surface on the bronze gear. Because of this worm gears put on in and improve with prolonged service while additional gears are wearing out. Ever-Power offers a wide collection of model configurations, sizes, ratios, and components from our standard products.
Fabricated Designs
If your application involves severe shock loads or possible housing damage from external sources (as in steel mills or mobile equipment applications) Ever-Power can provide fabricated steel housings with up to 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the tranny of higher horsepower amounts than are feasible with regular cast iron units. Extra heavy side plates connect the worm and equipment shaft bearing supports, assuring correct meshing of the apparatus 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 quickness and reversed engineered reducers for your application, be it a new project or a direct drop-in replacement for a competitor’s quickness reducer. Fabricated metal reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a direct drop-in substitute 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, ground and polished alloy steel worm. This mixture develops a easy, work-hardened mating surface of the bronze equipment which improves with prolonged service.
Worm gearing is a course 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 can be found from share in a wide variety of ratios, from only 4:1 to as much as 3600:1. The small design and structure allows worm equipment reducers to be positioned in a relatively small space. Thus, very high reductions in a limited package size can be achieved with this configuration. Our worm gear features the continuous sliding tooth action between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives provide users high reducing capacity for relatively low cost when compared to some other types of gearing.
The use 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 gear reducer is one kind of reduction gear box which includes a worm pinion input, an output worm equipment, and includes a right angle result orientation. This type of reduction gear container is normally used to have a rated motor quickness and produce a low speed output with higher torque worth based on the decrease ratio. They often times can solve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available because of the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of swiftness reducer because they provide the greatest speed decrease 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 assessment 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 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, non-corrosive, and nonmetallic.
Features
Our worm equipment reducers offer an option of a solid or hollow result shaft and show an adjustable mounting position. 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 called worm gearbox or worm speed reducers. Worm equipment reducers are utilized for speed reduction and raising the torque for electric engine drives. You can decide to install your NEMA electric motor to the reducer by using the NEMA C encounter flange or make use of a coupling. If you need a coupling for the output or input shaft find our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double result shaft and shaft insight and shaft result. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm gear reducers are used in low to moderate horsepower applications to reduce 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, left or dual output shafts or a hollow bore output. 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 reduction and improved torque, with higher tolerances for shock loading than helical equipment reducers.
In order to decide on a gearbox speed reducer, you will need to determine the required torque and service factor for the application. Click on “Specs” above for a desk that will aid in identifying the service element. For service elements above 1.0, multiply the mandatory torque by the provider factor.
