Embodiment Construction
[0016] Such as figure 2 As shown, the first embodiment of the present invention includes a first housing 1, a second housing 2, an oil passing pin 3, a first sealing ring 4, a second sealing ring 6, a third sealing ring 8, a first Retaining ring 5 and second retaining ring 7.
[0017] The first housing 1 and the second housing 2 have oil through holes. In order to achieve redundant sealing, one end of the first housing 1 and the second housing 2 are respectively provided with an axial angle connected to the oil through holes. The first annular groove and the second annular groove, an oil-passing pin 3 is installed between the oil-passing holes of the first housing 1 and the second housing 2, and the two ends of the oil-passing pin 3 are connected to the first annular groove and the second annular groove respectively. The grooves are matched, there is a through hole in the oil through pin 3; the two ends of the through hole of the oil through pin 3 are as consistent as possible w...
