Gear Coupling - Know The Facts About This Coupling

The curved tooth gear coupling is the result of many years experience in the field of mechanical power transmission. The gear couplings are distinguished by the compensation of axial, angular and parallel misalignment of the connected shaft and their mechanical flexibility. These couplings are used extensively paper machinery, cranes, metal rolling mills , plastic and rubber industry compressors , fan blowers and many other industries. These gear couplings is manufactured with crowned external teeth, consists of two hubs and two outer sleeves with internal spur teeth.

The outer sleeves and gear hubs are manufactured from carbon steel and hardened to the required degree. They are machined to fine tolerances for proper meshing of the gears as well as for inter- changeability.

Gear Coupling Feature
The gear coupling has hubs with multi crowned teeth at chamfering on teeth and flank teeth.

Crowned Flank

For making the tooth thickness greatest at the center of the tooth, the flanks of the teeth are crowned. This puts more teeth at the given teeth in contact for a given angle and assures larger contact area per tooth for higher torque requirements. The tooth loading takes place at the center where the tooth thickness is greatest. The crowned flank also provides optimum load distribution, accommodates all types of misalignment with minimum backlash and eliminate end-to-end tooth loading.

Crowned Chamfers

The faces of the teeth adjacent to the tips are chamfered to eliminate the interface with the sleeve tooth fillets. This allows the sleeves teeth to be in contact with the true involutes flank of the gear teeth thus assuring the freedom of misalignment. The heart of the gear couplings are the hub and a great tooth profile and superior design enables these coupling to operate satisfactorily under all operating conditions with long life and reliability.

Crowned Teeth
The tips of the teeth should be crowned. The crowned tip contacts the root of the internal gear teeth in the external sleeve, thus accurately piloting the sleeve with true concentric socket and ball action. This allows centering the sleeve physically to assure good physical dynamic balance and minimum diametric sleeve clearance under various misalignments and loading conditions.

The teeth of the gear hubs are generated by involute system and are crowned in nature. The amount of backlash values and crowning are chosen to ensure the best result greater flexibility, smooth operations and torque transmissions.
The internal teeth of the sleeves are produced in gear shaper ensuring a correct profile. These teeth are generated by involute system. The coupling sleeves are joined together with high tensile strength and are fitted with bolts by using the gasket in between them.

O Rings
In order to stop the leakage of lubricant and entry of the dust particles O- rings are provided at the end of the coupling hubs. The O -rings can also withstand high degree of temperature of 120 ° C.

Seal Carriers
Seal carriers are provided in order facilitate replacement and inspection of O- rings without the disturbing the alignment.
