Description

Technical Field

[0001] The utility model belongs to the technical field of host tile maintenance, and more specifically relates to a tile scraping mechanism. Background Art

[0002] The motor guide bearing is an important part of the main motor of the pump station. Its function is to guide the rotating parts of the unit to rotate accurately around the axis and bear the radial force of the rotating parts. Scraping the bearing can increase the contact points on the bearing surface and balance the force. At the same time, due to the oil filling of the scraping knife, an oil film is generated on the bearing surface, which improves the lubrication conditions, ensures the safe use of the bearing, and extends the service life. The main engine pump of Changshu Water Conservancy Hub uses a babbitt alloy bearing, and the guide bearing lining is babbitt alloy. As the unit runs, the guide bearing lining will rub against the thrust head and the motor shaft, and will wear out after long-term operation. The guide bearing may have defects such as shelling, cracks, hard spots and dense pores. These phenomena will reduce the operating efficiency and stability of the unit, so regular maintenance is required.

[0003] In view of the above problems, the guide bearing bushings generally need to be re-scraped for inspection and repair. If the equipment defects are serious, new parts may even need to be replaced. The traditional process is generally operated manually, which is labor-intensive, labor-intensive, and inefficient. In addition, its scraping accuracy cannot guarantee continuous consistency, and the processing range is not large. After manual scraping, it is often found that the gap between the guide bearing bushing and the anti-weight nut supporting it is uneven during the reinstallation process. That is, when scraping, the scraped part of the bushing lining surface becomes uneven and tilted. Because the processing accuracy requirements are high, the general processing unit is 0.01 mm, and it is difficult for humans to perceive the above situation.

[0004] Therefore, a processing device that can replace manual scraping and ensure maintenance accuracy is needed. Utility Model Content
