DRIVE DEVICE
Document Type and Number:
Japanese Patent JP2021076180
Kind Code:
A
Abstract:
To suppress flexural vibration of a crank shaft.SOLUTION: A crank shaft 40 is coupled to a piston of an internal combustion engine. At an end of the crank shaft 40, a disk-like drive plate is attached. A sensor plate 70 in a circular gear shape is attached between the end of the crank shaft 40 and the drive plate. When viewed from an axial direction of the rotational center 40a of the crank shaft 40, a virtual straight line X is drawn that passes the rotational center 40a and a referential pin center J which is a rotational center 40a of the crank pin 41 coupled to the piston closest to the drive plate among the crank pins 41 of the crank shaft 40. Here, among the flexure rigidity when the sensor plate 70 is bent such that the center of the sensor plate 70 is a center of the bending, the flexure rigidity of the sensor plate 70 when both ends in the virtual straight line X direction is brought closer is the weakest.SELECTED DRAWING: Figure 2
