Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, in particular to an alignment device for a gear coupling. Background Art
[0002] The blower rotor and the speed increaser are connected and driven by a gear coupling. The design speed of the blower is 5810r / min, so the coaxiality requirement of the blower is also relatively high. In the past, when replacing the blower rotor or replacing the sliding bearing, we used a magnetic base and a dial indicator to align the blower rotor and the speed increaser output shaft, but it was time-consuming and labor-intensive, and the accuracy was not high, and the operation cycle of the equipment could not be guaranteed. Due to the insufficient coaxial accuracy of the gas blower, the operation cycle of the equipment could not be guaranteed, resulting in an increase in the number of maintenance times, an increase in the labor intensity of employees, and a huge cost of spare parts consumed each year. Once the blower is shut down due to an accident, it will directly affect the supply of gas required for production in other factories and mines. Once the blower is shut down and causes gas to be released, it will have a greater impact on chemical technology and even the environmental protection work of the entire Anshan Iron and Steel Group. After searching, it is found that the domestic main method is to align the gear coupling with a dial indicator, and there is no device specifically used for aligning the gear coupling. Therefore, a gear coupling alignment device is provided. Utility Model Content

[0029] Working principle: drop the blower rotor onto the sliding bearing, and use a ruler and a feeler gauge to perform rough alignment first. Clamp the first circular fixing mechanism 1 and the second circular fixing mechanism 2 onto the outside of the coupling, insert the rectangular head of the plug pin 9 into the rectangular jack of the limit sleeve 5, and screw the locking nut to the external thread of the rectangular head.

[0030] ① The staff first measures the distance from the rear tile to the front tile, then measures the distance from the front tile to the installation position of the dial indicator on the special alignment tool, then measures the distance from the fan-shaped block on the alignment tool to the axis, and then calculates the coefficients of the front and rear feet and writes them into the corresponding database;
[0031] ② First find the horizontal sides and adjust the bearing bushing adjustment gaskets to make a1-a3≤0.05mm, s1-s3≤0.05mm, that is: a is the radial displacement, s is the axial displacement. ;
