Abstract:
1. A multiple-row, axially biased angular ball bearing, which is rotatable about an axis of rotation, comprising: a one-piece outer ring having raceways and shoulders; an inner ring having two inner ring halves, each of the inner ring halves having a groove formed in a radially inner surface area of each of the inner ring halves, at least one shoulder and a raceway, the shoulders of the outer ring and the shoulder of each of the inner ring halves delimit the raceways of the outer ring and the at least one raceway of the inner ring; bearing balls, which are arranged between the outer ring and the inner ring halves, in the raceways of the outer ring and the raceway of each of the inner ring halves, supported axially by the shoulders of the outer ring and the shoulder of each of the inner ring halves; and a securing ring having end clamps that both extend away from the axis of rotation of the ball bearing and engage with axial play in a tension-free state of the angular ball bearing into the groove formed in the radially inner surface area of each of the inner ring halves, wherein at least one inner ring half is axially displaceable in order to set a play-free pretensioning force, and an axial clearance is present, at least in an unbraced state, between axially inner end edges of the inner ring halves, wherein the axial clearance of the axially inner end edges of the angular ball bearing is equal to zero in the pretensioned state, and wherein the axial clearance of at least two end bearing faces of the angular ball bearing is greater than zero in a tension-free state.
