[0001] The utility model relates to the field of rotor shafts, in particular to a novel assembled rotor shaft. Background Art

[0002] The rotor shaft is an important component inside the motor, mainly composed of a shaft body, bearing positions, connection positions, and other auxiliary components. The motor converts electric power into torque for output through the cooperation of the internally fixed stator and the rotor on the rotor shaft. Therefore, the quality of the rotor shaft directly affects the operating stability of the motor equipment.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: Most of the existing rotor shafts have a fixed connection between the shaft body and the rotor. If damaged, they can only be replaced together, and it is difficult to replace multiple components individually, resulting in a high cost. Summary of the Utility Model

[0004] In order to improve the problem that most of the existing rotor shafts have a fixed connection between the shaft body and the rotor, and if damaged, they can only be replaced together, and it is difficult to replace multiple components individually, resulting in a high cost, this application provides a novel assembled rotor shaft.

[0005] The novel assembled rotor shaft provided by this application adopts the following technical solutions: The novel assembled rotor shaft includes a shaft body assembly and a connection assembly. The shaft body assembly includes a rotor sleeve, and the shaft body assembly includes a shaft rod. The rotor sleeve is sleeved on the outer end of the shaft rod. The connection assembly includes a mounting plate and two connection sleeves. The two connection sleeves are respectively located at the left and right ends of the shaft rod. Oil injection ports are provided at the tops of the two connection sleeves, and fastening bolts are threadedly connected to the inner sides of the tops of the two connection sleeves.

[0006] Further setting: The right end of the right connection sleeve is connected to the mounting plate through a bearing, and the left end of the left connection sleeve is fixedly connected with a threaded joint.

[0007] Further setting: Insertion holes are provided at both the left and right ends of the shaft rod, and insertion rods are fixedly connected to the inner ends of the two connection sleeves. The insertion rods are inserted into the insertion holes.

[0008] Further setting: Four card slots are provided at the outer end of the shaft rod, and four card strips are fixedly connected to the inner end of the rotor sleeve. The card strips are all located in the card slots.

[0009] Further setting: Threaded holes are provided on both the left and right sides at the top of the rotor sleeve, and the bottoms of the two fastening bolts are threadedly connected to the threaded holes.

[0010] Further setting: Lubrication chambers are provided at the inner ends of the two connection sleeves, and the lubrication chambers are all annularly arranged.

[0011] Further setting: The two groups of oil injection ports are respectively located at the tops of the two lubricating bins, and oil outlet holes are provided on the upper and lower sides of the inner ends of the two lubricating bins.

[0013] The present utility model provides a novel assembled rotor shaft. Through the cooperation of the shaft body assembly and the connection assembly, it solves the technical problem that in most existing rotor shafts, the shaft body and the rotor are mostly fixedly connected. If damaged, they can only be replaced together, and it is difficult to replace multiple components separately, resulting in a relatively high cost. By rotating the fastening bolt to separate it from the threaded hole, the connecting sleeve can be removed from the shaft rod. By using the cooperation of the card slot and the card strip, the rotor sleeve can be removed to separate it from the shaft rod. Through the modular design, it is convenient for personnel to flexibly disassemble, assemble, and replace each component. The structure is simple and stable, and has good practicability.

By using the cooperation of the card slot 107 and the card strip 108, the rotor sleeve 101 can be removed to separate it from the shaft rod 102. Through the modular design, it is convenient for personnel to flexibly disassemble, assemble and replace each component. The structure is simple and stable, and has good practicability.

[0027] Embodiment 2:

[0028] As Figures 1 - 4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution for a novel assembled rotor shaft: Threaded holes 106 are provided on both the left and right sides at the top of the rotor sleeve 101, and the bottoms of the two fastening bolts 105 are threadedly connected to the threaded holes 106.
