worm gear speed reducer

One 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 prolonged in either or both directions in horizontal or vertical plans adaptable to any installation requirement. Efficient electric motor speeds are decreased to slow speed requirements of several industrial machines in a single reduction.

The exclusive usage of the involute Helicoid Thread form (with leaving side contact) on the worm and gear offers high efficiencies, and long service existence. The hardened surface and polished alloy metal worm develops a soft, work hardened surface on the bronze gear. For this reason worm gears wear in and improve with prolonged service while other 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 worm gear speed reducer possible housing damage from external sources (as in steel mills or mobile gear applications) Ever-Power can offer fabricated steel housings with up to a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmission of higher horsepower levels than are feasible with standard cast iron models. Extra heavy part plates connect the worm and equipment shaft bearing supports, assuring appropriate meshing of the gear under all load circumstances. In smaller sizes, fabricated metal reducers are interchangeable with Ever-Power regular cast iron reducers.
Custom Designs
Ever-Power can provide custom speed and reversed engineered reducers for your application, be it a new project or a direct drop-in alternative to a competitor’s speed reducer. Fabricated steel reducers allow Ever-Power to complement a competitor’s footprint, centerline, and shaft elevation allowing a primary 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 style also includes a hardened, ground and polished alloy steel worm. This mixture develops a simple, work-hardened mating surface area of the bronze gear which improves with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This form of reducer provides even and quiet operation and permits the probability of large acceleration reductions. These gears can be found from share in a wide selection of ratios, from as low as 4:1 to as much as 3600:1. The compact design and construction allows worm gear reducers to be placed in a comparatively small space. Thus, high reductions in a restricted package size may be accomplished with this configuration. Our worm gear features the continuous sliding tooth action between worm and one’s teeth. This escalates the tolerance for weighty loads and shock loads. Worm gear drives provide users high reducing convenience of relatively low cost in comparison with various other types of gearing.
The usage 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 equipment reducer is one type of reduction gear package which contains a worm pinion insight, an output worm equipment, and features a right angle result orientation. This kind of reduction gear box is generally used to have a rated motor quickness and produce a low speed output with higher torque value based on the decrease ratio. They often times can resolve space-saving problems since the worm equipment reducer is among the sleekest decrease gearboxes available because of the small diameter of its result gear.
worm gear reducerWorm equipment reducers are also a favorite type of swiftness reducer because they provide the greatest speed decrease in the smallest package. With a higher ratio of speed reduction and high torque output multiplier, it’s unsurprising that lots of power transmission systems utilize a worm gear reducer. Some of the most typical applications for worm gears are available in tuning instruments, medical examining equipment, elevators, security gates, and conveyor belts.
SW-1 and SW-5
Torque Transmission provides two sizes of worm equipment 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 of these options are manufactured with durable compression-molded glass-fill polyester housings for a durable, long lasting, light-weight speed reducer that is 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 the SW-1 and the SW-5, however, can withstand shock loading better than other reduction gearbox styles, making them well suited for demanding applications.

Worm Gear Reducers also called worm gearbox or worm quickness reducers. Worm equipment reducers are used for speed reduction and increasing the torque for electric engine drives. You can decide to attach your NEMA motor to the reducer by using the NEMA C face flange or use a coupling. If you need a coupling for the result or input shaft discover our coupling section for choosing the coupling. We offer four assemblies left hands and right hands and double result shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures.

Description
The HDR Series worm gear 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, remaining or dual output shafts or a hollow bore output. The indirect drive models are shaft input-shaft output 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 services factor for the application. Click on “Specifications” above for a table that will aid in identifying the service factor. For service factors above 1.0, multiply the mandatory torque by the support factor.
