Normally bearing is installed by, cylindrical roller bearing part of the structure, size, and install, and its nature makes the cloud, installed when pressure is directly added to the ring's surface, pressure must be vertical, not by turning scroll body to put pressure on SKF bearings installed more generic methods are as follows:
Cylindrical roller bearings with shaft fits for transition fit, bearing washer bearing block hole of tie is clearance fit, in general are relatively easy to install fits, shaft in the bearing should be fixed on the axis, so as not to weeks, weeks turned, resulting in unnecessary wear. FAG bearings installed here, some more spinning installation, it can make the inner ring shaft combined with more tightly.
Cylindrical roll child bearing of outer ring with bearing block tie comparison pine, within ring with axis tie comparison tight have when, on can with installed cylindrical roll child bearing when using of professional of pressure machine to put bearing first pressure in axis Shang, then with axis, and bearing together installed to bearing block inside, in pressure installed of when Note bearing within ring of surface flush Shang, then pad a soft metal made of casing, material is copper of or is soft steel on can has, in Assembly casing diameter than axis neck diameter also large, od diameter than within ring of document side also small of when, To avoid pressure on the cage.
On the inspection results, may be used to NSK bearings or bearing savvy judgment.
Criteria based on the mechanical properties and importance vary depending on the level and check the cycle. As the injury, cylindrical roller bearings shall not be reused and must be replaced.
1) faults and defects of bearing components.
2) split of Raceway surface scroll surface.
Bearing fault identification method
Not by removing checks to identify or forecast TIMKEN bearings in a trouble-free operation, to improve productivity and economy are very important.
Major recognition methods are as follows:
1) by voice recognition
Voice recognition requires a wealth of experience. INA bearings full training is essential to achieve recognition voice and non-voice of cylindrical roller bearing. This should be done by hand as far as possible to make this work. Listening to audio or sound bar attached to the shell can be clearly heard on the bearing of the sound.
2) through to identify operating temperature
The method is a method to identify, is limited to use in running conditions don't change. To this end, the need for continuous recording of the temperature. Fails, not only temperature, irregular changes also occur.
3) through State recognition of lubricants
Sampling analysis of lubricants, mixed with foreign objects through the degree of dirt or metal powder for judgment. The method near the observation or large cylindrical roller bearings KOYO bearings are particularly effective.
