Shaft mounting for a disk file

摘要

PCT No. PCT/GB90/00021 Sec. 371 Date Sep. 6, 1991 Sec. 102(e) Date Sep. 6, 1991 PCT Filed Jan. 8, 1990 PCT Pub. No. WO91/10995 PCT Pub. Date Jul. 25, 1991A disk file has a frame with a non-rotatable shaft (2) extending in an axial direction between opposed wall portions of the frame. The shaft is clamped at one end to the frame by a screw (8) passing through an opening in the wall and axially into the shaft. This arrangement is susceptible to tilting of the shaft due to differential thermal expansion if the frame wall (1) and the shaft have dissimilar coefficients of thermal expansion. A bush (9) is located between the screw and the shaft. The bush is held in the wall by an interference fit, and has a coefficient of thermal expansion similar to that of the shaft. The inclusion of the bush greatly reduces problems due to differential thermal expansion.
