Embodiment Construction
[0018] The technical solution of the present invention will be described in detail below with reference to the embodiments of the accompanying drawings.
[0019] like figure 1 Shown is a schematic diagram of the basic structure of an embodiment of a damping device for axial vibration and noise reduction of the shaft system of the present invention, including: a stepping motor 1, an elastic coupling 2, a rotating shaft 3, a bearing seat 4, a damping Main body 5, thrust ball bearing 6, thrust plate 7, oil inlet nozzle 8, screw 9 and oil outlet nozzle 10. The motor 1 is connected to the rotating shaft 3 through the elastic coupling 2, and drives the rotating shaft 3 and the thrust disc 7 to rotate together. During the rotation, the rotating shaft 3 will generate axial vibration, which will be transmitted to the main body of the damper through the thrust disc 7 and the thrust ball bearing 6 5, the damper main body 5 will form an oil film damping effect after being squeezed, so as...
