Embodiment Construction
[0021] The present invention will be further described below in conjunction with the drawings.
[0022] An online detection method of iron filings content in slewing bearing grease, characterized in that: the method uses the grease online detection device of claim 3 to realize automatic sampling of grease, and coil inductance is caused by iron filings in the sampled grease. The amount change is used to determine the content of iron filings in the grease. The greater the change in inductance, the more iron filings in the grease, which can effectively determine the degree of wear in the raceway during the operation of the slewing ring.
[0023] The method also includes comparing the real-time detected inductance difference with the set warning value to determine whether the grease is invalid: when the real-time detected inductance difference is less than the set warning value, the starter motor 1 sends the grease back through the channel 10 In the slewing bearing, the opposite means ...
