が、駆動力入出力側の軸には構造上使用できない。However, the fixing method by shrink fitting has a feature that the final clearance of the bearing is reduced because the inner ring of the bearing is expanded by the stiffener of the bearing for obtaining the fixing force. For this reason, when trying to further increase the fixing force, there is a problem that the final clearance of the bearing is excessively reduced, which affects the rotational property of the bearing. In addition, the fixing method using the lock nut has a problem in that the lock nut is loosened due to disturbances such as expansion and contraction of the shaft due to load, vibration, and heat, and the bearing cannot be fixed. It leads to up.
Further, the fixing method using the end plate does not cause the bearing to escape if the plate is securely fixed, but cannot be used structurally for the shaft on the driving force input / output side.

The taper of these two rings is such that the diameter on the bearing side is small. At this time, the pressing ring 3 is inserted until it comes into contact with the inner ring 2a, and the pressing ring 3 and the fixed ring 4 come into contact with each other at their tapered surfaces. When these are cooled, the fixing ring 4 is shrink-fitted and fixed to the shaft 1 on the inner diameter side, whereby the inner ring 2a of the bearing 2 is fixed to an arbitrary position on the shaft 1.

る。Now, the relationship of the forces when the external force P acts on the bearing 2 will be described with reference to FIG. The direction of the external force P is converted into the external force Pa by the action of the taper. As a result, many of the external force P will act as a fixed force F 2 is a component force, bearing relief force F 1 is merely acting as a slightly component of the external force P, the fixed bearing 2 is securely Done.
