In the rotating shaft structure of the present embodiment, referring to fig. 2 to 3, the transmission member 4 has a first mounting hole 43 through which the rotating shaft 3 passes, and the first connecting portion 41 is provided on the outer peripheral surface of the transmission member 4; the rotating member 5 has a second mounting hole 52, the transmission member 4 is disposed in the second mounting hole 52, and the second connecting portion 42 is disposed on the inner peripheral surface of the second mounting hole 52.

By providing the resistance part 2, the connection body 51 drives the resistance part 2 to rotate, and the resistance applied when the rotation member 5 rotates is increased.
In the rotating shaft structure of the present embodiment, referring to fig. 2 to 4, the first connecting portion 41 is provided protruding from the outer surface of the transmission member 4, the second connecting portion 42 is a connecting groove provided on the inner wall of the second mounting hole 52, the first connecting portion 41 is inserted into the second connecting portion 42, and the first connecting portion 41 is movably provided in the second connecting portion 42; wherein, a preset included angle exists between the extending direction of the second connecting part 42 and the axis of the rotating shaft 3, and the value of the preset included angle ranges from 0 degrees to 90 degrees. Thus, after the first connecting portion 41 and the second connecting portion 42 are rotatably connected relatively, the first connecting portion 41 is located in the second connecting portion 42, an included angle exists between the extending direction of the second connecting portion 42 and the axis of the rotating shaft 3, and when the transmission member 4 moves axially, the first connecting portion 41 arranged on the transmission member 4 is limited by the second connecting portion 42 and can only move along the extending direction of the second connecting portion 42, so that the first connecting portion 41 converts the moving direction from axial direction to rotary motion to drive the rotating member 5 to start rotating.
In the rotating shaft structure of the present embodiment, referring to fig. 2, the first connecting portion 41 is a spherical structure provided on the transmission member 4; and/or the first connection 41 is relatively rotatably connected with the transmission member 4.
In the rotating shaft structure of the present embodiment, referring to fig. 2, the first connecting portion 41 is a spherical structure provided on the transmission member 4; the first connecting portion 41 is relatively rotatably connected with the transmission member 4. In this way, the first connecting portion 41 has a spherical structure, and friction between the first connecting portion 41 and the second connecting portion 42 can be reduced. The first connecting portion 41 is rotatably connected to the transmission member 4, and the first connecting portion 41 and the second connecting portion 42 can be prevented from being locked. In the rotating shaft structure of the present embodiment, referring to fig. 2, the first connecting portion 41 is screwed with the second connecting portion 42 to rotate the rotating member 5 through the transmission member 4.
Specifically, the first connection portion 41 and the second connection portion 42 may be constituted by a screw nut, and the second connection portion 42 may be driven to rotate by the axial movement of the first connection portion 41.

In the compressor of the present embodiment, a rotary shaft structure is included.
The invention provides a rotating shaft structure and a compressor, which reduce axial movement of a shafting when the shafting receives fluctuating axial gas force by converting axial movement of a rotating shaft 3 into rotary movement of a rotating part 5, ensure stable operation of the compressor, avoid excessive vibration of the compressor and ensure that the noise of the whole compressor is at a reasonable level.
