In this embodiment: when in use, the two rotor main bodies 17 drive the same rotating shaft 171 to rotate, and cooling liquid is injected into the two liquid inlet pipes 13, then enters the two cooling cavities 12 and cools the two stator main bodies 16 and the two rotor main bodies 17, and then is discharged from the two liquid outlet pipes 14;
During installation, through the motor main body 1 after the two connecting seats 21 on the connecting mechanism 2 are fixedly connected with the installation foundation, if vibration occurs, the second barrel 23 is driven to move up and down, the second barrel 23 compresses the spring 216 in the process of moving up and down, vibration transmitted to the connecting mechanism 2 by the motor main body 1 can be relieved through the compressed spring 216, heat is generated in the continuous stretching and compressing process of the spring 216, so that the damping effect of the spring 216 is deteriorated, at the moment, external cooling liquid flows into the first barrel 22 through the liquid inlet pipe 217, then the cooling liquid fills the whole first barrel 22, the second barrel 23 and the third barrel 24, finally the cooling liquid flows into the liquid outlet pipe 218 through a port of the liquid outlet pipe 218 positioned in the third barrel 24 and is finally discharged through the liquid outlet pipe 218, and heat generated when the spring 216 stretches can be carried away through the cooling liquid flowing through the inside the connecting mechanism 2, so that the spring 216 has a better damping effect even in the continuous use process is ensured;
Because a part of heat is transferred to the third barrel 24 through the assembly frame 15 in the running process of the motor main body 1, then the cooling liquid flowing through the third barrel 24 also carries away the heat transferred from the assembly frame 15 to the third barrel 24, and meanwhile, the cooling liquid also carries away the heat at the joint of the assembly frame 15 and the third barrel 24, so that the whole connecting mechanism 2 is not in an excessively high temperature state in the running process of the motor main body 1, and even if the subsequent motor main body 1 stops working, the first nut 25 can be matched with the assembly frame 15 of the second barrel 23 for only clamping and cooling;
Fatigue will occur in the process of extending and retracting the spring 216 for a long time, so that the cushioning effect of the spring 216 is deteriorated, at this time, the spring 216 can be inserted into the fourth barrel 26 and sleeved outside the second nut 211 through a sleeve tool, then the cylinder 219 driven by the second nut 211 and the externally threaded sleeve 210 rotate, the rotated externally threaded sleeve 210 drives the internally threaded sleeve 29 to move upwards, the internally threaded sleeve 29 drives the hollow plate 28 to move upwards through the fifth barrel 27, and the spring 216 is compressed through the upwardly moved hollow plate 28, so that the elasticity of the spring 216 lost due to fatigue can be compensated, and therefore, frequent replacement of the spring 216 is not required.
