Embodiment 1
[0036] Such as Figure 1-3 Shown, a kind of electric eddy current axial damper described in the present invention comprises:
[0037] Screw rod 1 and nut 2 adapted thereto;
[0038] A fixed cylinder 3 made of a magnetically conductive material is sleeved on the outside of the screw 1;
[0039] The inner drum 4 made of magnetically permeable material is connected with the nut 2 and sleeved between the screw rod 1 and the fixed drum 3. Several magnets 6 are arranged on the periphery of the inner drum 4, corresponding to the inner drum 4. The inner wall of the fixed cylinder 3 is provided with a conductor pipe 7;
[0040] The outer drum 5 made of magnetically conductive material is connected to the nut 2 and sleeved on the outside of the fixed drum 3. The inner wall of the outer drum 5 is provided with a conductor tube 7, and the corresponding peripheral edge of the fixed drum 3 is provided with Several magnets 6.
[0041] As a preferred solution of this embodiment, the fixed...
Embodiment 2
[0047] Such as Figure 4 As shown, an eddy current axial damper according to the present invention, on the basis of Embodiment 1, the eddy current axial damper also includes a guiding inner tube 8 and a guiding outer tube 9 .
[0048] The guide inner tube 8 is connected to the fixed cylinder 3, the guide outer tube 9 is connected to the screw 1, one end of the guide inner tube 8 is sleeved on one end of the guide outer tube 9, and the guide The outer wall of the inner tube 8 is attached to the inner wall of the guide outer tube 9 and can slide relatively. The inner wall of the guide inner tube 8 is connected with at least one support ring 81 , and all the support rings 81 are connected to the outer wall of the fixed cylinder 3 .
[0049] With this structural setting, the damper needs to be made longer to achieve the maximum damping force and damping coefficient required by the design. When the damper is placed in a horizontal state, the deflection of the middle part of the dam...
