Abstract (en)

[origin: CN112540529A] A sub-assembly (100) composed of external components, including a bolting device (3) placed between a first component (1) and a second component (2) that press a joint (9) together. The bolting device(3) fixes the first component (1) and the second component(2) together by axially blocking the first component (1). The bolting device (3) cooperates with the second component (2) to surround a ball(6), and the ball (6) occupies a directional accommodation cavity (260) in the second component (2) or the bolting device (3). A cavity (261) is included and has a depth greater than the diameter of the ball (6). The cavity (261) is surrounded by a channel (262). The depth of the channel (262) is less than the diameter of the ball (6) and is defined by a limit boundary (270). When a gravitationalfield and/or a magnetic field acts, the ball (6) can occupy both the directional accommodating cavity (260) included in the bolting device (3) or the second member (2) and the complementary accommodating cavity (26) whose depth is less than the diameter of the ball (6). Thereby, when the ball (6) is supported on the channel (262) and the complementary accommodating cavity (26) at the same time. The relative driving between the bolting device (3) and the second component (2) is realized by the ball (6).
