Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a concentric correction structure for a long-shaft motor. Background Art

[0002] With the continuous update of the structures of fans and pumps, the motor shaft needs to be lengthened to a certain length to meet the requirements of the installation structure, thus the long-shaft motor came into being.

[0003] The long-shaft motor is the same as the conventional motor. The difference is that the length of its rotating shaft extending out of the motor body is longer. Since the shaft is relatively longer than that of the traditional motor, the installation requirements for the rotating shaft are also higher. To a certain extent, the installation of the rotating shaft affects its smoothness during rotation. For example, if the installation angle at the rear end of the rotating shaft deviates, vibration is bound to occur at the front end, affecting the use stability of the long-shaft motor.

[0004] When the existing long-shaft motor is installed with the motor housing and the rear cover, a certain margin is usually given to the screw connection, which causes a certain deviation after the rear cover is installed, resulting in vibration at the front end of the long shaft. Content of the Utility Model

[0005] The purpose of the utility model is to provide a concentric correction structure for a long-shaft motor.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A concentric correction structure for a long-shaft motor, including a motor housing, a rear cover is arranged at the rear end of the motor housing, a long shaft is arranged inside the motor housing, the long shaft passes through the rear cover, at least two opposite clamping bodies are arranged on the motor housing, annular rings are respectively arranged at the front end and the rear end of the clamping body, and the long shaft is arranged inside the annular rings; a plurality of extension blocks are arranged on the rear end of the motor housing, and adjusting rods which abut against the outer walls of the annular rings are arranged on the extension blocks.

[0007] It is further set as: A plurality of embedding grooves are arranged on the motor housing, and the clamping bodies are embedded in the embedding grooves.

[0008] It is further set as: The extension blocks are grouped in pairs, and the extension blocks in the same group are respectively arranged on both sides of the embedding groove.

[0009] It is further set as: Fixing holes are arranged in the embedding grooves, and fixing screws which are arranged in the fixing holes are arranged on the clamping bodies.

[0010] In summary, the utility model has the following beneficial effects: Through this concentric correction structure, the concentricity of the rear end can be ensured during the installation of the long shaft. When the rear cover is installed with deviation, it can be adjusted through the adjusting rod, so as to ensure the concentricity and the operation stability of the long-shaft motor.

[0013] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0014] The concentric correction structure of the long shaft motor includes a motor housing, a rear cover is arranged at the rear end of the motor housing, a long shaft is arranged inside the motor housing, and the long shaft passes through the rear cover.

[0015] As Figure 1 shown, 8 clamping bodies are arranged on the motor housing, and the relative placement positions of the clamping bodies on the motor housing are evenly distributed. Since the overall cross-section of the motor is usually circular, all eight clamping bodies face the center of the long shaft. The support frame of the motor housing (i.e., the conventional feet for keeping the motor stably installed) is installed after the clamping bodies are installed, and can avoid the clamping bodies.

[0016] Rings are respectively arranged at the front end and the rear end of the clamping body, and both ends of the long shaft are respectively inserted into the front and rear rings. The ring at the front end of the clamping body can be disassembled, so as to facilitate the installation of the clamping body.

[0017] A number of embedded grooves are arranged on the motor housing, and the clamping bodies are embedded in the embedded grooves, so as to reduce the protruding part of the clamping bodies and ensure the normal operation of the heat dissipation structure of the motor housing.

[0018] A number of extension blocks are arranged on the rear end of the motor housing, and adjusting rods that abut against the outer wall of the ring are arranged on the extension blocks. The extension blocks are in pairs, and the extension blocks in the same pair are respectively arranged on both sides of the embedded groove. In this way, the extension blocks can also cooperate with the embedded groove to work and ensure the stability of the clamping body.

[0019] Fixing holes are arranged in the embedded grooves, and fixing screws that pass through the fixing holes are arranged on the clamping bodies.

[0020] This specific embodiment is only an interpretation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications that do not contribute creatively to this embodiment according to needs after reading this specification, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
