Linear motion mechanism and the center mechanism of the tire vulcanizer of tire vulcanizer

摘要

Bladder extension height and shaping height, etc. position control is sufficiently performed of, to provide a linear motion mechanism of the corresponding possible tire vulcanizer to different tire sizes. Hydraulic drive center mechanism 1 which is an example of a center mechanism of a tire vulcanizer according to the present invention includes a Baguheddo 2, the hydraulic cylinder 3. Also, cylinder tube 4 is formed in a thick, sensor hole portion 7 is provided near an outer peripheral surface. Sensor hole 7 penetrates into the bottom side of the cylinder tube 4, the linear sensor 8 having heat resistance and flexibility are inserted.
