The tiles installed on the fixed bracket of the crankshaft and cylinder block to play the role of bearing and lubrication are usually called crankshaft bearing shells.
Crankshaft bearing shells are generally divided into two types: bearing shells and flanging bearing shells. Flanging bearing bush can not only support and lubricate the crankshaft, but also play the role of axial positioning of the crankshaft (only one axial positioning device can be set on the crankshaft).
Install the new bearing into the seat hole, and each end of the upper and lower plates shall be 0.03-0.05mm higher than the bearing pad seat plane. To ensure that the bearing bush fits closely with the seat hole and improve the heat dissipation effect.
The experience of checking the length of bearing bush is as follows: install the bearing bush, install the bearing bush cover, tighten the bolt at one end according to the specified torque value, and insert a gasket with a thickness of 0.05mm between the cover at the other end and the bearing bush seat plane. When the torque of screwing the bolt at this end reaches 10-20n · m, if the gasket can not be pulled out, it indicates that the bearing length is too long, file the end without positioning tenon down; If the gasket can be pulled out, the length of bearing bush is suitable; If the gasket cannot be pulled out without tightening to the specified torque value, it indicates that the bearing bush is too short and should be re selected.
