Title: Disk carrying mechanism for disk player
Inventor: HIDA NOBUYOSHI
IPC: G11B17/04
Filed: 1986-05-28
Abstract: PURPOSE:To use the rotating force of a motor during turning of an arm at a prescribed angle by turning the arm at the prescribed angle after the straight going motion of a tray is stopped. CONSTITUTION:A tray 1 is pulled out, and a driving gear 5 is engaged with a linear part of a rack gear; and when the gear 5 is rotated clockwise by a motor M16 in this state, the tray 1 is pulled in to carry a disk to a reproducing device. When the gear 5 reaches an arc part of the gear 9, an arm 8 is turned, and the gear 5 continues rotating. Since the radius of curvature of the arc part and that of the arm are equal to each other, the tray 1 enters into the still state and is held there. The rotation angle of the arm 8 is read, and the rotation of the motor 16 is stopped when this angle is a prescribed value. After the operation of a player is terminated, the arm 8 is reversed to move the tray 1 in the direction of an arrow A, and this extent of advance is read, and the rotation of the motor 16 is stopped when this extent corresponds to a prescribed position. A gear 15 is formed in the rotation center of the arm 8 to obtain the rotating force.

Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the frequency of maintenance inspection by providing a stress variation effect reduction construction reducing the effect of stress variation between the end face of a bearing and a packing ring. SOLUTION: Because a radial load of about 10 ton is loaded on the axle 1 of a railway rolling stock, bending is generated on the rotating axle 1. Then stress between the end face of an inner ring 2c and the end face 5a of a packing ring 5A and stress between the end face of an inner ring 2d and the end face 5b of a packing ring 5B are periodically varied synchronizing with rotation of the axle 1. But, because the end faces 5a, 5b of the packing rings 5A, 5B are formed with films for absorbing the stress variation, fretting due to such stress variation is prevented from generating on the end faces of the inner rings 2c, 2d, the end faces 5a, 5b of the packing rings 5A, 5B, and the like. As a result, mixing of abrasion powder of metal into the bearing is avoided, and hence the raceway surface can be prevented from chapping and the like.
