As we all know, noise is caused by vibration. The general size of this type of bearings has been stabilized, including low-transmission materials and lubricating oils. Lubricating greases with good lubrication performance are used to minimize noise. Better, the so-called mute means to reduce the noise of the bearing as much as possible. In fact, there is still noise during the rotation.
So what aspects should be paid attention to silent bearing installation?
First, disassemble and clean the crankshaft components to ensure that the oil passage inside the crankshaft is clean and unobstructed.
Second, the crankshaft is inspected, and if it is cracked, it must be replaced. Carefully check the crankshaft main journal, connecting rod journal and their transition arcs. All surfaces must be free of scratches, burns and bumps.
Third, check the crankshaft main journal and connecting rod journal, and repair them according to the repair level after the size exceeds the limit. The crankshaft journal repair is as follows:
Fourth, check the hardness requirements of the crankshaft journal and connecting rod journal, which must meet the technical requirements. Otherwise, it should be reprocessed to meet usage requirements.
Fifth, the radial runout of the crankshaft and the radial runout of the thrust facing the common axis of the main journal must meet the technical requirements. Otherwise, it must be corrected.
Sixth, the parallelism of the connecting rod journal axis to the common axis of the main journal over the entire length must meet the technical requirements.
Seventh, when the front and rear transmission gears of the crankshaft are cracked, damaged, and worn seriously, the crankshaft should be replaced.
Eighth, if the crankshaft balance weight bolt is cracked, it must be replaced. After the crankshaft is replaced with a balance weight or a balance weight bolt, it is necessary to perform a dynamic balance test on the crankshaft assembly to ensure that the unbalance amount meets the technical requirements.
Ninth, if the flywheel and pulley bolts have cracks, scratches or elongation exceeding the limit, they should be replaced.
Tenth, carefully check the shock absorber of the crankcase feet. If it is damaged, rubber is aging, cracked, deformed or cracked, it must be replaced.
Eleventh, when assembling the crankshaft, pay attention to the installation of the spindle bush and thrust bush. Check the crankshaft axial clearance and tighten the main bearing cap vertical and horizontal bolts as required.
