BEARING SUPPORT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a bearing support structure which prevents a bearing on a rotary shaft supported by a box from producing noises caused by radial vibration and axial vibration and the bearing is supported so as not to have any damage caused by an axial load onto the bearing. SOLUTION: In the bearing support structure that the bearing 3 on the rotary shaft 2 is inserted into the box 1 of a bellows pump, the bearing 3 is fixed without having any gap between the bearing and the box 1 so that a peripheral surface of an outer ring 3a of the bearing 3 is pressed in a radial direction by a stop pin 4 engaged with a screw hole 6 in the box 1.
