worm gear speed reducer

worm gear speed reducer
Single reduction worm gearing offers high ratio reduction with few shifting parts in a close-coupled compact drive. The right angle arrangement of driving-to-driven machine takes a minimum of space. Input and output shafts can be extended in either or both directions in horizontal or vertical arrangements adaptable to any installation requirement. Efficient electric motor speeds are decreased to gradual speed requirements of many industrial machines in a single reduction.

The exclusive use of the involute Helicoid Thread form (with departing side contact) on the worm and gear offers high efficiencies, and lengthy service lifestyle. The hardened surface and polished alloy metal worm develops a easy, work hardened surface area on the bronze gear. For this reason worm gears use in and improve with extented service while other gears are deteriorating. Ever-Power offers a broad selection of model configurations, sizes, ratios, and accessories from our standard products.
Fabricated Designs
If the application involves serious 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 a 48″ center distances. Fabricated housings provide optimum rigidity and strength that allows the transmitting of higher horsepower amounts than are feasible with standard cast iron products. Extra heavy aspect plates connect the worm and equipment shaft bearing supports, 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 provide custom swiftness 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 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 manufactured from phosphorous bronze. Our design also incorporates a hardened, ground and polished alloy steel worm. This combination develops a simple, work-hardened mating surface area of the bronze gear which boosts with prolonged service.
Worm gearing is a course of equipment reducers that utilizes right angle, nonintersecting shafts. This style of reducer provides easy and quiet operation and permits the likelihood of large swiftness reductions. These gears are available from stock in a wide variety of ratios, from only 4:1 to as much as 3600:1. The compact design and building allows worm gear reducers to be placed in a relatively small space. Thus, high reductions in a restricted package size can be achieved with this configuration. Our worm gear features the constant sliding tooth action between worm and one’s teeth. This increases the tolerance for large loads and shock loads. Worm gear drives offer users high reducing convenience of 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 use worm gearing are: conveyors, mixers and bucket elevators.

-Housing:One time we casting creats great rigidity for severe impacts. Outer cooling fins and inner lubrication essential oil diversion channel design to increase heat dissipation.
-Worm Shaft: Manufactured with Carbon alloyed Metal S45C or SCM415, precison machined and carburized to HRC45 or HRC60, after that for precision tooth grinding to make sure maximum contacting.
-Worm Wheel: Manufactured with Carbon alloy ALBC2, teeth are machined by precision CNC hobbing machine to sustain high impact.
A worm gear reducer is one type of reduction gear box which consists of a worm pinion input, an output worm gear, and features a right angle output orientation. This kind of reduction gear box is generally used to take a rated motor velocity and produce a low speed output with higher torque worth based on the reduction ratio. They often times can resolve space-saving problems because the worm gear reducer is among the sleekest reduction gearboxes available due to the small diameter of its result gear.
worm gear reducerWorm gear reducers are also a popular type of speed reducer because they offer the greatest speed decrease in the tiniest 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 gear reducer. Some of the most typical applications for worm gears can be found in tuning instruments, medical screening 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 these options are produced with tough compression-molded glass-fill polyester housings for a durable, long lasting, light weight speed reducer that’s also compact, noncorrosive, and nonmetallic.
Features
Our worm gear reducers offer a choice of a solid or hollow result shaft and feature an adjustable mounting placement. Both SW-1 and the SW-5, however, can withstand shock loading better than other decrease gearbox styles, making them perfect for demanding applications.

Worm Gear Reducers also known as worm gearbox or worm rate reducers. Worm equipment reducers are used for speed reduction and raising the torque for electrical engine drives. You can choose to install your NEMA engine to the reducer by using the NEMA C encounter 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 hand and right hands and double result shaft and shaft input and shaft output. Interchangeable with many worm gear manufactures. See data sheet in product overview for diamensions. Unless you see your type, please Contact Us.

Description
The HDR Series worm equipment reducers are found in low to moderate horsepower applications to lessen 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 result shafts or a hollow bore output. The indirect drive models are shaft input-shaft result boxes for make use of 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 gear reducers.
In order to decide on a gearbox speed reducer, you will have to determine the mandatory torque and services factor for the application. Click on “Specs” above for a table that will aid in identifying the service aspect. For service elements above 1.0, multiply the mandatory torque by the support factor.
