Gear Couplings: Benefits and Applications

Gear Couplings is a type of flexible Couplings & Fittings , intended to connect two shafts together at their ends for the purpose of transmitting power, to transfer rotational movement from one shaft to another. Available in a wide range of sizes they are capable of transmitting high torque at high speed. Each coupling consists of 2 two hubs with external gear teeth, hubs are joined by flange sleeves with internal gear teeth, and flanges are bolted together. There are three types of teeth designs used in gear couplings: straight teeth, crowned with constant radius, crowned with variable radius. The coupling is in normally enclosed. Coupling parts include gaskets and O-rings in order to prevent the leakage of the lubricant filled inside the coupling. General purpose gear couplings are usually made from carbon steel. Because of their design, these torsionally stiff Couplings can withstand some shock loading, but they cannot absorb significant amounts of it.

Lubrication Importance

The Couplings require periodic lubrication, every 1-2 years depending on duty and type of lubrication. If properly maintained (good lubrication and reasonable alignment), the coupling has a service life of 3-5 years and in many cases 5-10 years.

Some have a sleeve made of plastic (nylon, high molecular plastic), these don’t require lubrication. They have much lower torque capacity than steel made couplings and are used mainly on small pumps.

Misalignment

Gear Couplings & Fittings can accommodate angular, parallel and axial misalignment. This is due to clearance between gear teeth. Some have crowned teeth. This design allows higher angular misalignment hence parallel as well. Excessive misalignment will shorten you coupling life significantly. It is always good to read the manufacturers installation instructions.

Benefits of using GEAR BOXES & COUPLINGS

High torque density
3 types of misalignment (angular, parallel, axial)
High torque at high speeds

Gear couplings are commonly used in metal industry applications such as steel or wire mills. They provide big value in places where high torque to size ratio is necessary as well as high speed capabilities. For Source info, Click here!
