Title:
ANGULAR CONTACT ROLLER BEARING AND METHOD AND DEVICE FOR THE ASSEMBLY THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/020908
Kind Code:
A1
Abstract:
The invention relates to an angular contact roller bearing (1) comprising an inner bearing ring (2) that has, on its outer lateral surface (3), an inner raceway (4) which is oblique relative to the bearing rotational axis (AL) and an edge (5) which limits this raceway (4) at its smallest diameter, an outer bearing ring (6) that has, on its inner lateral surface (7), an outer raceway (8) which is also oblique relative to the bearing rotational axis (AL) and an edge (9) which limits this raceway (8) at its largest diameter as well as a plurality of roller rolling bodies (10) which are provided between the bearing rings (2, 6) and roll on their raceways (4, 8), said roller rolling bodies being held at equal distances from each other in the circumferential direction by a bearing cage (11). This angular contact roller bearing (1) is, according to the invention, characterized in that a tangent to the outer lateral surface (3) of the inner bearing ring (2) and a tangent to the inner lateral surface (7) of the outer bearing ring (6) are, at least in the region of the raceways (4, 8), planar extending obliquely in opposite directions relative to the bearing rotational axis (AL) and the raceways (4, 8) of both bearing rings (2, 6) are each incorporated into these lateral surfaces in a conical manner, and in that the edges (5, 9) created thereby and limiting the raceways (4, 8) at one end are, as a result, integral with the bearing rings (2, 6). Furthermore, the invention also relates to two variants of a method and a device for assembling the angular contact roller bearing.
