SKF bearing measurement error, tolerances shall be 10% the following. Exploits the margin of measurement error of 10%~33% in General, as tolerance grade increases, the proportion of error larger or smaller tolerances, higher proportion of errors, while imports bearing more than IT5 tolerances, it is hard to reach 10%. Measurement error does not mean that the test tolerances can relax 10%, but to give some safety margin in order to ensure user acceptance by criteria.
SKF bearings in each part of the process, in order to obtain bearing size, shape and location precision of the machined surface, had to make adjustments to the machine tools, jigs and tools, any adjustments will inevitably bring about a certain degree of error. SKF bearing parts in machining often requires different production batches and accuracy, using adjustment methods are also different.
In the bearing of these stages in the life cycle is very important to obtain maximum service life of SKF bearings. Through the correct implementation of the maintenance and use of appropriate tools, you can dramatically extend the life of SKF bearing, increase factory productivity and production efficiency. Including temperature, noise, speed and vibration measuring instrument during the run, use the basic State monitoring tool detect bearing status on a regular basis is important, such as temperature, vibration and noise measurement. Detect potential faults can be found on a regular basis, helping to prevent unexpected downtime. Therefore, you can schedule equipment maintenance plan in conformity with production planning, increase factory productivity and production efficiency.
Common method of bearing radial clearance adjustment is as follows:
1, for cylindrical and oval-shaped bearing top clearance, can be manually scraping or when circumstances allowed the Institute to SKF bearing surfaces and mats methodologies, adjusts.
2, the wedge tilting bushing of oil, does not allow repair tile scraper, gap is not due to pad should be replaced in due course. Pad with adjustable thickness, you can adjust block behind the tile and stainless steel pad under, or thinning method of thickness of block adjustment adjust the amount of Watts. Note on a wedge tilting bushing of oil, with Group tile thickness error should be less than 0.01mm.
3, multi-fixed oil wedge Bush, does not in principle allow scraping and adjust the clearance between Bush sleeves, gap is not new tiles should be replaced in due course.
4, for cylindrical and oval-shaped bearing backlash, scrape or SKF bearings can be manually developed siding plus pad after turning in scraping method of adjustment
