Description

Technical Field

[0001] The utility model relates to an improved invention of a compressor coupling, in particular to an improved invention of a coupling device that takes into account crankshafts with different piston forces. Background Art

[0002] The coupling consists of a flywheel and a half-coupling. The half-coupling is used to connect the motor to one side of the flywheel, and the crankshaft flange of the flywheel unit is connected to the other side of the flywheel. The crankshafts of different piston force units have different sizes, and accordingly, the distribution circle diameters of the corresponding flanges and their mounting center holes will also be different. Therefore, different units require different flywheels for matching, and it is necessary to disassemble and replace the flywheel to connect the motor, which increases the commissioning installation time and the number of commissioning couplings. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a coupling device that takes into account crankshafts with different piston forces.

[0004] To solve the above technical problem, the utility model is implemented by adopting the following technical scheme: The coupling device that takes into account crankshafts with different piston forces includes a flywheel, a half-coupling, and a crankshaft flange of the flywheel unit. The motor side of the flywheel is connected to the half-coupling, and the crankshaft side of the flywheel is connected to the crankshaft flange of the flywheel unit. Its characteristics are as follows: A coupling spacer is also provided on the crankshaft side of the flywheel, and the coupling spacer is installed between the flywheel and the flange. A number of first holes and second holes are annularly provided on both the flywheel and the coupling spacer. The first holes and the second holes are staggered on the flywheel, and the first holes and the second holes overlap on the coupling spacer. The distribution circle of the first holes is Φ570mm, and the distribution circle of the second holes is Φ550mm. The first holes are matched with the connection holes of the flange of the 36-ton unit, and the second holes are matched with the connection holes of the flange of the 25-ton unit. A number of third holes are also annularly provided on the coupling spacer. The third holes are staggered from the second holes, and the distribution circle of the third holes is Φ500mm. The third holes are matched with the connection holes of the flange of the 16-ton unit.

[0005] There are 12 first holes evenly distributed, 8 second holes evenly distributed, and 12 third holes evenly distributed.

[0006] Two circles of mounting holes are annularly provided on the half-coupling, and the distribution circles of the mounting holes are Φ570mm and Φ430mm respectively.

[0007] The beneficial effect of the utility model is that for the improved coupling device that takes into account crankshafts with different piston forces, by adding a coupling spacer and the mutually staggered first holes and second holes, and the mutually staggered second holes and third holes, the unit can achieve the connection between the same motor and different units by connecting the corresponding flywheel mounting holes, saving the commissioning installation time and reducing the number of commissioning couplings.

[0015] The drawings show the structure of the present utility model. The following further explains its relevant details in conjunction with the drawings. In this embodiment, referring to the attached Figure 1-6 , the coupling device for the crankshaft that can accommodate different piston forces includes a flywheel 1, a half coupling 2, and a crankshaft flange of the flywheel unit 3. The motor side of the flywheel 1 is connected to the half coupling 2, and the crankshaft side of the flywheel 1 is connected to the crankshaft flange of the flywheel unit 3. A coupling pad 4 is also provided on the crankshaft side of the flywheel 1, and the coupling pad 4 is installed between the flywheel 1 and the flange 3. A number of first holes 5 and second holes 6 are annularly provided on both the flywheel 1 and the coupling pad 4. The first holes 5 and the second holes 6 are staggered on the flywheel. The first holes 5 and the second holes 6 overlap on the coupling pad 4. The distribution circle of the first holes 5 is Φ570mm, and the distribution circle of the second holes 6 is Φ550mm. The first holes 5 are matched with the connection holes of the flange of the 36-ton unit, and the second holes 6 are matched with the connection holes of the flange of the 25-ton unit. A number of third holes 7 are also annularly provided on the coupling pad 4. The third holes 7 are staggered from the second holes 6. The distribution circle of the third holes 7 is Φ500mm. The third holes 7 are matched with the connection holes of the flange of the 16-ton unit.

[0016] The working principle of the present utility model is that, for three series of units, by connecting the corresponding mounting holes of the flywheel 1 and the coupling pad 4, the connection between the same motor and different units can be achieved, saving the commissioning installation time and reducing the number of commissioning couplings. Among them, the setting of the coupling pad 4 makes the arrangement of the first holes 5, the second holes 6, and the third holes 7 more reasonable, avoiding interference with the mounting holes of the half coupling 2 on the flywheel 1.

[0017] As a specific implementation of a further improvement, the first holes 5 are provided with 12 evenly distributed ones, the second holes 6 are provided with 8 evenly distributed ones, and the third holes 7 are provided with 12 evenly distributed ones.

[0018] As a specific implementation of a further improvement, two circles of mounting holes 8 and 9 are provided on the half coupling 2, and the distribution circles of the mounting holes 8 and 9 are Φ570mm and Φ430mm respectively. When installing a 36-ton unit, the half coupling 2 selects the mounting hole with a distribution circle of Φ570mm, so that the first hole 5 communicates with the mounting hole, and the same bolt can be used to penetrate and fasten them together; when installing a 25-ton unit and a 16-ton unit, the half coupling 2 selects the mounting hole with a distribution circle of Φ430mm to avoid interference.

[0019] In summary, the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
