Title: Thermal strain restraining method for main spindle head
Inventor: MATSUZAWA KAZUYOSHI
IPC: B23Q11/12
Filed: 1989-08-04
Abstract: PURPOSE:To balancedly restrain thermal strain by injecting and spreading cooling oil against the inner wall of a main spindle head, and intercepting heat transfer from a heat source to the inner wall without direct cooling of the heat source. CONSTITUTION:At least two cooling pipes 20, 20 are arranged in parallel along both side corners of the upper part of the inner space of a box shaped main spindle head 10. Many upward and outward nozzles N1, N2 are drilled on the cooling pipes 20, cooling oil CO is injected and spread from the cooling pipes 20 to the upper face 3a and both side faces 6a, 7a of the inner wall of the main spindle head 10. At this time, direct spreading to a gear train G as a heat source is avoided. Spreaded cooling oil CO is withdrawn with pipings P2 through the lower face 4 to an oil cooler and circulated. A part of the cooling oil CO is dispersed to the gear train G and indirect cooling and lubrica tion is performed. Hereby, heat transfer from the heat source to the inner wall is intercepted, and thermal strain is balancedly restrained.
