[0005] Preferably, the annular protective cover is provided with a sleeve portion capable of contacting the connecting rod shaft.

[0006] Preferably, structural reinforcement ribs are respectively provided on both sides of the semicircular gland.

[0007] Preferably, the semicircular gland is locked onto the bearing seat after four bolts penetrate the flat gasket.

[0008] Compared with the prior art, the utility model has the following advantages: two bearings are installed at both ends of the tension connecting rod shaft at the left roller support and the right roller support, and semicircular glands are installed on the left roller support and the right roller support respectively. The two semicircular glands are locked to the left roller support and the right roller support by four bolts inserted into flat washers. The outer edge of the annular protective cover is fixed by the circular protective cover hole formed, and the closed protective cover directly closes the end of the connecting rod shaft. The protective covers of the two structures separate the bearing end face from the external environment, which can effectively reduce the entry of impurities into the bearing.
