Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] refer to figure 1 and figure 2 , a flexible heat pipe used for cooling the surface of the high-speed electric spindle shaft provided by the present invention. Firstly, the main components of the high-speed electric spindle are briefly introduced. The typical structure of the electric spindle mainly includes the rotating shaft 1. The front end cover 2 is used for sealing protection, the rear end of the rotating shaft 1 is matched with the rear bearing assembly 5, and the rear end cover 6 is used for sealing protection, the motor rotor is interference fit with the electric spindle shaft 1, and the motor stator is fixed with the electric spindle housing 4 together and are therefore not shown in the figure. When the electric spindle is running, due to factors such as frictional heat generation of the bearing, loss of the motor, and wind motors of the rotating s...
