Abstract

PURPOSE:To maintain the rectilinear property of the motion of the main shaft by supporting the main shaft to a frame by mens of a thrust bearing, a bearing, a needle bearing, etc. and preventing the transmission of radial vibration through the revolution of the feed screw connected to a main shaft motor to the main shaft. CONSTITUTION:The main shaft 54 of the machine tool is supported by means of the thrust bearing 62 which mounts the bearing 52 engaged with the feed screw 48 connected to the servomotor 10 to the upper end section of the main shaft 54. The bearing 52 is connected by means of a guide plate 72 set up to the frame 14 and a guide pin 70 slid and guided by the guide plate, and moves the main shaft 54 before and behind on the feed screw 48. The main shaft 54 is supported into the frame 14 by means of the sliding needle bearing 78 through adjusting bolt nuts 80, 82 and a guide member 76. Accordingly, vibration in the radial direction with the revolution of the feed screw 48 due to the displacement of the core of the feed screw 48 and the core of the motor 10 is absorbed, and the rectilinear property of the longitudinal motion in the axial direction of the main shaft 54 is maintained.
