Multi-row tapered roller bearing and transmission having such a bearing

A bearing assembly comprising:

• at least first, second and third raceway elements that are each separable from each other, the first and second raceway elements being disposed side-by-side in an axial direction of the bearing assembly and opposing the third raceway element in a radial direction of the bearing assembly, and
• at least first, second and third rows of truncated-cone-shaped rolling elements, the first and second rows being disposed between the first raceway element and the third raceway element and the third row being disposed between the second raceway element and the third raceway element,
• wherein axially adjacent rollers in the first and second rows of truncated-cone-shaped rolling elements share a common center axis and have a same cone angle such that the axially adjacent rollers have a common apex point,
• wherein the rolling elements of the first and second rows commonly roll on a first raceway of the third raceway element, and
• the rolling elements of the third row roll on a second raceway of the third raceway element, the second raceway is not parallel to the first raceway,
• a cage disposed between the first and third raceway elements such that the first and second rows of truncated-cone-shaped rolling elements are properly oriented relative to each other along the first raceway,
• a lubrication groove positioned between the first and second raceway elements and configured to deliver lubricant between the first and second raceway elements.
