Abstract

PURPOSE: An equipment to enable high accuracy rotation transmitting at high speed in the turning head cylinder of VTR which uneveness of rotation is small and side way motion is small.
CONSTITUTION: A turning head cylinder 21 installed to the top end of the rotating shaft 14 through a bushing 7 is rotated at a high speed of approx. 1,800r.p.m. with installing a head 3. In this case, the above rotating shaft 14 is supported to rotate freely with a radial ball bearing 17, 18 as the first bearing, the above rotating head cylinder 21 is supported with multiple arc air bearing 15, 16 as the second bearing, elastic construction section 13 which eqivalent spring constant is small than other section of the rotating shaft 14 is formed on the rotating shaft 14 between the first and second bearing. This elastic construction section 13 is formed to be smaller than the sectional area of other shaft sections in its shaft diameter. Additionally, edge- shaped bearing groove 20 is formed in the above bearing section 16.
