Latest Patents
Kawanabe's latest patents include innovative designs that enhance the functionality of mechanical components. One of his patents is for a tensioner that applies tension to a force transmitting member. This tensioner features shaft members that interconnect through threaded portions. The first shaft member is designed to rotate relative to a casing while being restrained from axial movement. The second shaft member, which is fixed against rotation, can move axially. A torsion spring is incorporated to apply torque in one direction to the first shaft member, and a torque switching member is included to adjust frictional torque based on the rotation of the first shaft member.
Another significant patent is for a return spring used in a clutch mechanism. This design utilizes a compression coil spring housed within the clutch to urge the clutch piston back to its original position. The effective number of turns of this compression coil spring is limited to two or fewer, with specific parameters for the end-turn portion to optimize performance. This innovative approach ensures that the compression coil spring remains in a compressed state throughout the clutch piston’s operating stroke.
