Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a three-meter centering device suitable for various types of couplings. Background Art

[0002] When assembling the pump head and motor, the pump coupling and the motor coupling need to be aligned. The three-meter method is usually used for alignment. However, most factories still use the double-meter method of magnetic base for alignment. The two dial indicators must be at an angle of 180°, and the two magnetic bases need to be adsorbed on the metal surface. However, not all types of couplings have enough space for the magnetic base to be adsorbed, resulting in the inability to install the magnetic base and the dial indicator. In addition, the magnetic base is sometimes limited by the installation space, so that the magnetic base does not fit the shaft diameter completely, resulting in distorted dial indicator readings. When aligning with the two-meter method, the axial movement generated when rotating the coupling will cause the dial indicator reading to be inaccurate, resulting in insufficient alignment accuracy, thereby affecting the installation accuracy. Therefore, a three-meter alignment device suitable for multiple types is needed. Utility Model Content
