  • Crank shaft assembly for bicycle
    Publication number: 20040266575
    Abstract: A crank shaft assembly includes a socket, a crank shaft, two roller bearings, two mounting portions, two covers, and two steel ball sets. Thus, the roller bearings and the steel ball sets are arranged in different axial directions to bear the forces of two different directions. In addition, the roller bearings and the steel ball sets are arranged in different axial directions to increase the force bearing area of the crank shaft assembly, thereby preventing from producing stress concentration, so as to increase the lifetime of the crank shaft assembly.
