[0002] Figure 1 This is a common compressor main unit connection structure for existing screw compressors. The compressor main unit 1 is connected to the motor (not shown) via a cylindrical flange 2. The rotating shaft 3 of the compressor main unit 1 is connected to the output shaft of the motor via a coupling 4. Therefore, the coupling 4 needs to be installed on the rotating shaft 3 of the compressor main unit 1.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0019] See also Figure 2As shown, an embodiment of the present invention provides a coupling installation tool, including a hanging plate 5, the top of which is provided with a lifting eyebolt hole 6, through which a lifting eyebolt can be installed to vertically lift the hanging plate 5. A positioning shaft 7 is provided on one side of the hanging plate 5, and the positioning shaft 7 is perpendicular to the hanging plate 5. A shaft sleeve 8 is coaxially mounted on the end of the positioning shaft 7 away from the hanging plate 5, and the coupling 4 to be installed can be movably mounted on the shaft sleeve 8. A limiting boss 9 is provided on the end of the shaft sleeve 8 away from the hanging plate 5 to facilitate centering and limiting of the coupling 4 mounted on the shaft sleeve 8.

[0020] Furthermore, the sleeve 8 is removably connected to the positioning shaft 7. Depending on the shaft diameter of the coupling 4 to be installed, a suitable sleeve 8 can be installed on the positioning shaft 7, allowing the tooling to meet the installation requirements of couplings 4 with various shaft diameters. Specifically, as shown in the embodiment of the present invention, the sleeve 8 can be coaxially mounted on the end of the positioning shaft 7 and fastened together using a countersunk screw. Of course, the sleeve 8 can also be removably mounted on the positioning shaft 7 through threaded connections, clip-on connections, or other methods, which will not be detailed here.

[0021] The hanging plate 5 is provided with a connection hole 10, through which the hanging plate 5 can be connected to the cylindrical flange 2 of the compressor main unit 1. Figure 4 As shown, when the hanger plate 5 is connected to the cylindrical flange 2, the positioning shaft 7 extends into the cylindrical flange 2 and is aligned with the rotating shaft 3 of the compressor main unit 1. This allows the coupling 4 on the sleeve 8 to mate with the rotating shaft 3, facilitating installation. The hanger plate 5 is also uniformly provided with multiple lightening holes 11, which remove material and reduce weight while ensuring overall strength.

[0022] During assembly, first install the matching sleeve 8 on the positioning shaft 7 according to the shaft diameter of the coupling 4 to be installed; then put the coupling 4 to be installed on the sleeve 8, and lift the fixture and coupling 4 through the eye bolts on the top of the hanging plate 5. Figure 3 、 Figure 4 As shown, after aligning the hole of coupling 4 with the rotating shaft 3 of the compressor main unit 1, the hanging plate 5 is connected to the cylindrical flange 2 of the compressor main unit 1. The positioning shaft 7 can then be used to support and position the coupling 4, maintaining the coupling 4 in the assembled position docking with the rotating shaft 3. Finally, through the observation port on the cylindrical flange 2, a rubber hammer is used to install the coupling 4 to the main unit side to the appropriate position, so that the coupling 4 is separated from the tooling, and the tooling can be removed to complete the installation. The installation is convenient and can effectively prevent injury to the installer.
