TECHNICAL FIELD

[0001] The utility model relates to high -power pod motor installation technical field, concretely is a polar grade high -power pod motor installation fixed structure. BACKGROUND

[0002] The existing polar grade high -power pod motor installation scheme adopts the scheme of directly interference connection, that is, the motor shell and the motor cage are directly interference connected, and there is no elastic link in the connecting process, the elastic deformation amount of the motor shell and the motor cage is used to overcome the transmission torque between them, that is, the motor shell produces elastic deformation, and the motor cage also produces elastic deformation, which is a common installation mode in the general ordinary motor stator installation mode.

[0003] However, when used in the installation of the stator of the polar grade high -power pod motor, the deformation amount is not balanced, since the polar grade high -power pod shell needs to be in contact with ice blocks, the structure stiffness thereof is large, and the motor cage has small stiffness, and when interference connection is performed between the motor cage, the uneven deformation amount is easy to cause plastic deformation of the motor cage, resulting in damage of the motor cage, and further affecting the structural safety of the motor stator.

[0004] To solve the above problems, the polar grade high -power pod motor installation fixed structure is used to overcome the uneven stiffness between the motor shell and the motor cage, and ensure the reliable and safe interference connection therebetween. UTILITY MODEL CONTENTS
