    摘要: The torque variation absorbing device comprises a driving plate, a flywheel, and a spring mechanism, a torque limiting mechanism and a hysteresis mechanism installed between the driving plate and the flywheel. The torque limiting mechanism is located radially inside of the spring mechanism and radially inside of an oil drain hole bored in the flywheel. The side plate at one side of the driving plate is bent toward the flywheel and covers a gap between the driving plate and the flywheel. The side plate at the other side of the driving plate is made of a steel plate and the load supporting points on both sides of the side plate are spaced from each other in the radial direction.

    摘要: There is provided a V-groove machining method and apparatus which, by measuring the depth of a V groove cut by a cutting tool and correcting the cutting depth of the cutting tool based on the measurement data, enables high precision machining of four-sided pyramids having vertices of a uniform height. The V-groove machining method includes the steps of: feeding a cutting tool relative to a workpiece in a first direction to create a first V groove, extending in the first direction, in the surface of the workpiece, and repeating this machining operation to create first V grooves at a predetermined pitch; moving the cutting tool along one of the first V grooves and scanning the first V groove with a distance sensor, disposed near the cutting tool, to measure the distance to the bottom of the first V groove, thereby detecting undulation of the bottom of the first V groove along the first direction; and feeding the cutting tool relative to the workpiece in a second direction orthogonal to the first direction to create a second V groove in the surface of the workpiece, and repeating this machining operation while correcting the position of the cutting tool in the machining position for each second V groove based on the results of detection of the undulation, thereby creating second V grooves at a predetermined pitch.
