worm gear speed reducer

Single reduction worm gearing provides high ratio reduction with few moving parts in a close-coupled compact drive. The proper 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 plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to sluggish speed requirements of many industrial machines in a single reduction.

The exclusive use of the involute Helicoid worm gear speed reducer Thread form (with departing side contact) on the worm and gear offers high efficiencies, and long service lifestyle. The hardened surface and polished alloy metal worm develops a easy, work hardened surface on the bronze equipment. For this reason worm gears put on in and improve with extented service while additional gears are deteriorating. Ever-Power offers a wide selection of model configurations, sizes, ratios, and add-ons from our standard product line.
Fabricated Designs
If the application involves severe shock loads or feasible housing damage from external sources (as in steel mills or mobile products applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide maximum rigidity and strength that allows the transmitting of higher horsepower amounts than are possible with standard cast iron models. Extra heavy side plates connect the worm and gear shaft bearing supports, assuring correct meshing of the gear under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power standard cast iron reducers.
Custom Designs
Ever-Power can provide custom velocity and reversed engineered reducers for your application, be it a fresh project or a direct drop-in alternative to a competitor’s rate reducer. Fabricated steel reducers allow Ever-Power to complement 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 manufactured from phosphorous bronze. Our design also incorporates a hardened, surface and polished alloy steel worm. This mixture develops a even, 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 probability of large quickness reductions. These gears are available from share in a wide selection of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm equipment reducers to be positioned in a comparatively small space. Thus, very high reductions in a limited package size may be accomplished with this configuration. Our worm equipment features the continuous sliding tooth actions between worm and the teeth. This escalates the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of 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 utilize worm gearing are: conveyors, mixers and bucket elevators.

A worm equipment reducer is one type of reduction gear box which includes a worm pinion input, an output worm gear, and includes a right angle output orientation. This kind of reduction gear box is generally used to have a rated motor rate and create a low speed output with higher torque worth based on the decrease ratio. They often can resolve space-saving problems because the worm equipment reducer is among the sleekest reduction gearboxes available due to the little diameter of its output gear.
worm gear reducerWorm equipment reducers are also a popular type of acceleration reducer because they offer the greatest speed decrease in the smallest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that many power transmission systems make use of a worm equipment reducer. Some of the most typical 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 offers 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 of these options are manufactured with tough compression-molded glass-fill up polyester housings for a long lasting, long lasting, light-weight speed reducer that is also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer an option of a good or hollow result shaft and feature 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 perfect for demanding applications.

Worm Gear Reducers also referred to as worm gearbox or worm velocity reducers. Worm equipment reducers are used for speed decrease and increasing the torque for electric powered electric motor drives. You can decide to mount your NEMA electric motor to the reducer by using the NEMA C encounter flange or use a coupling. If you need a coupling for the output or input shaft observe our coupling section for choosing the coupling. We offer four assemblies left hand and right hand and double output shaft and shaft insight and shaft result. Interchangeable with most worm gear manufactures. Observe data sheet in item overview for diamensions. If you don’t see your type, please Contact Us.

Description
The HDR Series worm equipment reducers are found 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 result. The indirect drive models are shaft input-shaft output boxes for make use of with sprocket or pulley drive systems. They provide an effective low priced solution to speed reduction and increased 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 required torque and program factor for the application. Click on “Specifications” above for a table that will assist in identifying the service aspect. For service elements above 1.0, multiply the required torque by the support factor.
