Document Type and Number:
Japanese Patent JP6871885
Kind Code:
B2
Abstract:
To create connection of a shaft and a hub with concentricity at slight production costs.SOLUTION: A system has a vacuum pump having a shaft 10 and a hub 12. At least at one first outer peripheral part, the shaft and the hub have plural corresponding centering faces. The centering faces form first centering means. At least at one second outer peripheral part different from the first outer peripheral part, at least one entrainment body 20 is provided on the hub, and at least one concave part 18 corresponding to the entrainment body is provided on the shaft. The entrainment body is engaged with the concave part for conducting a torque, and has two side walls separated from each other in a circumferential direction. The side walls cooperate with the inner wall of the corresponding concave part, so as to form second centering means separated from the first centering means in the circumferential direction together with the inner wall.SELECTED DRAWING: Figure 2
