Title: Disk driving device
Inventor: WATANABE MASAYOSHI
IPC: G11B19/20
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To reduce vibration and noise even when a recording disk large in deviation center of gravity at the time of high speed rotation is rotated by providing a catching part catching a ball for compensating dynamic balance in an inner peripheral part side of a ring groove. SOLUTION: Plural small protrusion 15 are formed on an outer peripheral part of a guide ring 10 engaged with an inner wall part of a ring groove 8 in the direction of ring width. When acceleration is performed from low speed rotation, balls 9 which are collected downside by gravity are rotated together with a turn table 1 by frictional force between the balls and the wall of the ring groove 8, and moved upward of the ring groove 8, but at the time of low speed rotation, the balls 9 are returned to the original downside by gravity even when desire to lift upward since the frictional force is small. A dropping ball 9 is caught by the protrusion 15 by attaching the guide ring 10 having the protrusion 15 to an inner peripheral wall of the ring groove 8, the ball is lifted upward again by rotation of the turn table 1, and the ball 9 is made easy to carry upward.

Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a gear transmission, and easily operate it by constituting a hydraulic motor in a variable displacement type, and changing its motor capacity to large or small capacity by an external operation member of a housing. SOLUTION: When a motor 3 is composed of a hydraulic motor of a variable displacement type, even if a delivery quantity from a pump 2 is constant and a pressure difference between front and rear parts of the motor 3 is constant, when capacity of the motor 3 is increased by operating an external operation member 13 of a housing 12, rotating speed can be sloweed by increasing torque of its output shaft 5, and therefore, it can be adapted to a work time characteristic. To the contrary, when capacity of the motor 3 is reduced, the rotating speed can be increased by reducing torque of its output shaft 5, and it can be adapted to a towing time characteristic. Therefore, there is no need to arrange a sub-transmission in a gear transmission 6, and since it becomes sufficient when it is composed of only a function of a speed reducer, its structure is simplified.
