WIPO Patent Application WO/2014/103899

A1

Provided is an assembling device for an angular ball bearing, the assembling device being capable of quickly installing and collecting balls for the angular ball bearing. An angular ball bearing (1) has an inner ring (10), an outer ring (20), and balls (30), and an assembling device (50) can install balls (30) into the gap (S) between the inner ring (10) and the outer ring (20) and can collect the balls (30) from the gap (S). The assembling device (50) is provided with: an inner ring jig (64) which can rotate the inner ring (10) and the outer ring (20) relative to each other; an outer ring jig which can displace the inner ring (10) and the outer ring (20) relative to each other along a plane perpendicular to the axial direction; a curved arm (78) which supports the balls (30) by the upper surface (78c) of the curved arm (78), can rotate in the circumferential direction, and can be displaced in the axial direction; and a ball collection pin (68) which, while the balls (30) are installed in the gap (S), can be disposed in a portion which is not occupied by the balls (30) and which can prevent the circumferential displacement of the balls (30).
