[0010] Preferably, the bearing bush is further provided with:

[0011] The clamping grooves are provided on both sides of one of the groups of bearing bushes, and the bearing bushes are clamped to each other through the clamping grooves.

[0012] Preferably, the oil filling holes are symmetrically distributed about the vertical center line of the shaft seat upper shell, and the oil filling holes are interconnected with the diversion channel.

[0013] Preferably, the diversion channel and the oil outlet holes are communicated with each other, and the oil outlet holes are symmetrically distributed with respect to the vertical center line of the shaft seat upper shell.
