First, how to install the split sliding bearing
The split sliding bearing, also known as the bearing bush, consists of two upper and lower bearing pads. If the diameter of the bearing bush is too large, the diameter of the bearing bush will be too small after being installed in the bearing seat. After the bearing seat is installed, the bearing bush will vibrate in the bearing housing, which will shorten its service life. Under normal circumstances, when the bearing bush is in the free state, the end faces should be higher than the bearing seat. When the bearing bush is pressed to the center of the bearing seat, the end face should be 0.05-0.10mm higher than the bearing seat. After assembly, the bearing bush should be able to fit tightly. On the bearing housing. The bearing bush can be pressed with a wooden hammer or a wooden board with a hammer by hand. Do not directly hit the middle of the bearing pad with a hammer.
Second, installation precautions
The split type sliding bearing should be placed positively when pressing, and the force should be even to prevent the pressure deviation. The oil groove and oil hole on the bearing bush should be aligned with the oil hole on the connecting rod. Between the outer surface of the bearing shell and the bearing, no paper or copper sheet is allowed to change the fit condition and adjust the bearing clearance. Because the padding cannot accurately ensure the gap between the shaft and the bearing, especially the pad, the heat transfer of the bearing bush is destroyed and the life is shortened.
