When the oil is injected into the top of the bearing 7, besides providing lubrication for the bearing 7, the inside of the bearing 7 can be flushed, so that dust entering into the bearing 7 can be flushed down, and falls down along with the oil from the bottom of the bearing 7, and enters into the first oil receiving disc 6022 and the second oil receiving disc 6028, then enters into the intermediate tank from the first oil return hole 6023 and the second oil return hole 6024, finally flows back into the oil storage cavity from the oil return pipe 1320, waste is avoided, and the oil is filtered by the filter 1312 before entering into the oil storage cavity, so that the cleanness of the oil flowing back into the oil storage cavity is ensured.
As shown in fig. 16, a second seal ring is provided between first drip pan 6022 and upper nipple 1306 to provide a seal at the junction.
The present invention is not limited to the above-described embodiments, and any changes in shape or structure thereof are within the scope of the present invention. The scope of the present invention is defined by the appended claims, and those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and spirit of the present invention, but these changes and modifications fall within the scope of the present invention.
