Gear Coupling

Gear couplings connect two shafts together through interlocking teeth that transmit power, absorb vibration and allow for slight angular displacement. Gear couplings transport torque between two shafts that are not coaxial or collinear. Each shaft consists of a flexible joint, which is fixed to the shaft. The joints of the shafts are connected by a spindle, a third shaft.

Gear couplings offerefficient torque transmission in a compact mechanism and permit a highdegree of axial movement. However, gear couplings require piloting andmay malfunction at very high or very low torques. Crowned tooth flanksallow angular displacement to occur between each gear. Two coaxialshafts can also be connected by a single joint gear coupling, known asa gear-type flexible or flexible coupling. Slight misalignments of 0.5°to 5° are tolerated by this type of gear coupling. Gear couplings and universal jointsare used in similar applications, most predominantly in the automobileindustry. While gear couplings have higher torque density, universaljoints induce lower vibration than gear couplings. The gear teeth in agear coupling have high backlash, which can contribute to vibration, toallow for angular misalignment. Gear couplings are found in allrear-wheel and four-wheel driven passenger cars.


Ina gear coupling, the two shafts being joined meet in the third shaftwhich contains gears. The teeth interlock with each other to rotateand, in doing so, they transfer torque, power and energy. Every gearcoupling has differing stall speeds, which is the highest speed thatthe gears can turn when maximum input power is applied. Flexible shaftcouplings such as gear couplings are necessary because duringoperation, some types of shafts tend to shift, causing misalignment.Shaft movement is caused by bumps or vibration and it results inparallel, angular or skewed shaft misalignment. Flexible shaftcouplings provide efficient accommodation for moderate shaftmisalignment that occurs when the shafts' axes of rotation becomeskewed. There are many different kinds of shaft couplings. The bellows couplinghas two hubs and a thin walled metallic bellows and can accommodate allthree types of misalignment. Single beam couplings are usually made ofa single piece of aluminum and have a system of spiral cuts that allowit to bend in order to accommodate angular misalignment. Multiple beamcouplings consist of two to three overlapping beams that addressproblems of torsional rigidity. The Oldham couplingconsists of three components: two hubs and a central plastic disk. Itaccommodates slight parallel misalignment, while providing almost zerobacklash.
