Description

Technical Field

[0001] The utility model relates to the technical field of motor shafts, in particular to a motor shaft that can be quickly installed. Background Art

[0002] The motor shaft is a mechanical device. The strength and rigidity of the motor shaft are guaranteed. When the motor is running, the mechanical force and torque on the shaft vary with the type of motor and the transmission mechanism. The main forces are: the gravity of the rotor assembly itself, the one-way impact force caused by the eccentricity of the rotor, and the centrifugal force of the unbalanced weight. The load torque acting on the shaft by the transmission machinery at the shaft extension end, etc., the motor shaft will inevitably be damaged during long-term use.

[0003] Prior art, such as a motor shaft recorded in patent publication number CN216530922U, includes a shaft, one end of which is fixedly connected to a connecting disk, and a plurality of notches for inserting connecting bolts are provided on the annular side surface of the connecting disk: a nut is threadedly connected to the connecting bolt, and a limit strip for limiting the position of the connecting bolt in the notch is provided on the side of the notch facing the nut, and the two ends of the limit strip are respectively inserted in the first limit groove and the second limit groove, and the first limit groove and the second limit groove are symmetrically provided on two parallel sides of the notch, and a pressure piece for preventing the nut from loosening is installed on the side of the limit strip facing the nut, thereby improving the efficiency of disassembly and eliminating the need to completely unscrew the nut from the connecting bolt.

[0004] In actual use, the disassembly efficiency of the device is relatively high, but during installation, the nuts still need to be tightened on the bolts, which takes a long time to install.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of the utility model is to provide a motor shaft that can be quickly installed and can effectively solve the above technical problems.

[0007] In order to achieve the purpose of the utility model, the following technical scheme is adopted: a motor shaft that can be quickly installed, comprising: a shaft body, a side shaft, a fixing frame, a limit assembly connecting the shaft body and the side shaft, and a fixing assembly fixing the side shaft;

[0008] The fixing assembly comprises: a fixing rod, a fixing plate slidably mounted on the fixing rod, a fixing ring fixedly mounted on the fixing rod, a spring surroundingly mounted on the fixing rod, and a fixing block fixedly mounted on the fixing rod.

[0009] Furthermore, the limiting assembly includes a mounting end and limiting blocks fixedly mounted on both sides of the mounting end.

[0010] Furthermore, an arrow is fixedly mounted on the top of the fixing rod.

[0011] Furthermore, a limit rod is fixedly installed on the outer wall of the fixing frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a motor shaft that can be quickly installed. By pressing the fixing rod, the lower end of the fixing rod is inserted into the fixing through hole on the installation end head, and the fixing rod is rotated to make the fixing block on the fixing rod pass through the limiting hole on the fixing plate. The lower end of the fixing rod is fixed to the side shaft, and the fixing rod is loosened. The spring torsion makes the fixing block deviate from the limiting hole and fixes the fixing rod, thereby achieving the purpose of quickly installing the motor shaft.
