Description

Technical Field

[0001] The utility model belongs to the technical field of main shafts and relates to a main shaft structure used for a water pump motor. Background Art

[0002] Patent No. CN202121599519.8 discloses a motor shaft in the field, including a main shaft and a secondary shaft. The main shaft and the secondary shaft are an integrated structure. A plurality of movable grooves distributed in an annular array are provided at one end of the main shaft away from the secondary shaft. A movable block is arranged in the movable groove. A fixed block is fixed to the outer end surface of the movable block by bolts. A clamping block is fixed to the top of the fixed block by bolts. A mounting hole is provided on the clamping block. A screw is rotatably connected to the inner wall of the bottom of the movable groove through a bearing. The screw and the movable block are threadedly connected. A plurality of through holes distributed in an annular array are provided on the circumferential outer wall of the main shaft. The top of the screw extends above the through hole. A straight groove is provided on the top of the screw. The screw is rotated by a tool to move the movable block upward, driving the fixed block and the clamping block to move synchronously, and then the disassembly is completed. A separate mounting hole is provided, which can be used in conjunction with the screw to improve the fixing effect and reduce the number of screws used. The cooperation of the limit groove and the limit block can improve the stability of the moving process. However, in actual use, the disclosed water pump motor shaft needs to be replaced as a whole when damaged because the replacement method is relatively inconvenient, and the length of the main shaft cannot be selected. Therefore, we design a main shaft structure for a water pump motor. Summary of the invention
