Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an axial positioning assembly structure of a rotor shaft. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor rotor is the rotating part of the motor and is an important component of the motor. Therefore, an axial positioning assembly structure for the rotor shaft is required.

[0003] At present, many motor rotors are fixed to the motor shaft as one. However, due to the gravity of the rotor assembly and its load itself or the installation accuracy, friction occurs between the rotor and the end face of the bearing during the operation of the motor, causing increased vibration and wear of the motor. At the same time, the outer ring of the bearing is affected by factors such as motor vibration and will also move, which will cause the rotor shaft to move in the axial direction, which is not conducive to the stable use of the motor. In addition, when positioning the rotor shaft, the positioning method is single and its practicality is reduced. Utility Model Content

[0004] The purpose of the present utility model is to provide an axial positioning assembly structure for a rotor shaft, so as to solve the problem raised in the above background technology that many motor rotors and motor shafts are currently fixed as one body. However, due to the gravity of the rotor assembly and its load itself or the installation accuracy and other reasons, during the operation of the motor, friction occurs between the rotor and the end face of the bearing, causing increased vibration and aggravated wear of the motor. At the same time, the outer ring of the bearing is also affected by factors such as motor vibration, which will also cause some movement, thereby causing the rotor shaft to move in the axial direction, which is not conducive to the stable use of the motor. In addition, when positioning the rotor shaft, the positioning method is single, and the practicality is reduced.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an axial positioning assembly structure for a rotor shaft, comprising a shell, a rotor movably mounted inside the shell, rotor shafts rotatably mounted on both sides of the rotor, mounting plates movably mounted on both sides of the shell, mounting grooves formed on one side of the mounting plates, bearings fixedly mounted on the inside of the mounting grooves, a clamping groove formed on one side of the mounting plates, rubber pads movably mounted on the inside of the clamping grooves, clamping plates movably mounted on the inside of the rubber pads, and a circular plate fixedly mounted on one side of the clamping plates.

[0006] Preferably, a support rod is fixedly installed around the surface of the circular plate, and a bolt is rotatably installed on one side of the support rod, and one side of the bolt passes through the support rod and the mounting plate and extends to the inside of the shell.

[0007] Preferably, a connecting tube is fixedly installed between the mounting plate and the rotor, and the inner surface of the connecting tube is movably connected to the outer surface of the rotor shaft.

[0008] Preferably, a fixing plate is fixedly sleeved on the surface of the connecting pipe, a connecting ring located on the right side of the fixing plate is fixedly sleeved on the surface of the connecting pipe, and a circular groove is formed around the surfaces of the connecting ring, the mounting plate and the circular plate.

[0009] Preferably, a screw is movably installed inside the circular groove, a nut is threadedly sleeved on the surface of the screw, and an annular plate is fixedly installed on one side of the screw.

[0010] Preferably, a storage groove is provided on one side of the circular plate, and a sealing gasket is movably installed inside the storage groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This is an axial positioning assembly structure for the rotor shaft. During daily use, the operator places the rubber pad inside the slot and then moves the circular plate. The circular plate then drives the clip plate and the support rod to slide. At this time, the clip plate is placed inside the slot, and the support rod is also close to the outer surface of the mounting plate. At the same time, the bolt is turned and screwed into the support rod, the mounting plate and the housing. The provision of the clip plate and circular plate can prevent the rotor shaft from axial displacement, thereby improving the stability of the motor operation.

[0013] This axial positioning and assembly structure of the rotor shaft, during daily use, the operator places the fixing plate and the connecting ring between the rotor and the mounting plate, and then the connecting pipe is also placed on the surface of the rotor shaft. At this time, the sealing gasket is placed inside the storage groove, and the annular plate is moved.
