ROTARY TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JPS5554718
Kind Code:
A
Abstract:
PURPOSE:To reduce the irregular rotation and rolling, by forming a fluid-lubricated bearing between a rotary shaft and a fixed sleeve. CONSTITUTION:A rotary head assembly of VTR has its rotary head cylinder 13 fixed to a rotary shaft 15 through a bush 14. The thrust force at the lower end of the rotary shaft 15 is supported by a pivot bearing 36. A radial fluid bearing 34 together with a thrust bearing 35 at the lower portion of the rotary shaft 15 forms a fluid bearing for supporting the radial and thrust force of the rotary shaft 15. Lubricating oil 41 is fully filled in around the radial fluid bearing 34 and up to the opening 42 of the fixed sleeve. This guarantees high precision revolution of the rotary head cylinder.
