[0008] An accommodating chamber provided in the oil-seeping sleeve;

[0009] A maintenance channel is provided outside the oil-seeping sleeve, wherein the maintenance channel is communicated with the accommodating chamber;

[0010] A sealing plug cooperates with the maintenance channel.

[0011] Optionally, the oil-seeping sleeve is made of polyvinyl chloride, polyethylene terephthalate, polypropylene or polyethylene.

[0012] Optionally, it also includes a plurality of oil seepage holes arranged on the outer ring of the oil seepage sleeve, the plurality of oil seepage holes are all connected to the accommodating cavity, and the plurality of oil seepage holes are all used to communicate with the bearing seat.
