1.内燃机曲轴箱的缸套支承面和带有凸缘支承的湿式气缸套的密封,其方法是直接通过在上部导向部分和凸缘支承之间的切槽中压紧一个密封圈。由图可以看出,在气缸套(1)上部导向部分(3)范围内还有一个较宽的环形槽(8),在这个槽中还布置了第二个密封圈(10)。 2.按要求1来密封,从图看出,对装第二道密封圈(10)的环槽(8),加工成倒角(9)可以降低切口应力。 3.按要求1和2来进行密封,从图中还可看出,由于较宽的环槽(8),上部导向部分(3)的长度最大约可减小40％。
1. The sealing of the liner support surface of the internal combustion engine crankcase and the wet cylinder liner with flange support by pressing a sealing ring directly in the groove between the upper guide part and the flange support. It can be seen from the figure that there is also a wider annular groove (8) in the upper guide part (3) of the cylinder liner (1), in which a second sealing ring (10) is also arranged. 2. Seal as per requirement 1. As can be seen from the figure, the chamfer (9) of the ring groove (8) with the second seal ring (10) reduces the notch stress. 3. Sealing is carried out according to the requirements 1 and 2. It can also be seen from the figure that the upper guide part (3) can be reduced in length up to approximately 40% due to the wider ring groove (8).
