Abstract
Official abstract text for this publication.
A planetary roller bearing is disclosed. The planetary roller bearing includes an outer ring including a first set of teeth, an inner ring including a second set of teeth, and planetary rolling elements arranged between the outer ring and the inner ring. The planetary rolling elements each include a third set of teeth configured to engage with the first set of teeth and the second set of teeth. A height of at least three successive teeth gradually increases from an axial end of a selected set of the first, second, or third sets of teeth.
First claim
Opening claim text (preview).
The invention claimed is: 1. A planetary roller bearing comprising: an outer ring including a first set of teeth, an inner ring including a second set of teeth, and planetary rolling elements arranged between the outer ring and the inner ring, the planetary rolling elements each including a third set of teeth configured to engage with the first set of teeth and the second set of teeth, wherein a height of at least three successive teeth gradually increases from an axial end of a selected set of the first, second, or third sets of teeth. 2. The planetary roller bearing according to claim 1 , wherein the planetary rolling elements are held on an end side in cage disks. 3. The planetary roller bearing according to claim 1 , wherein middle teeth of the selected set of the first, second, or third sets of teeth have identical heights. 4. A planetary roller bearing comprising: an outer ring including a first set of teeth, an inner ring including a second set of teeth, and planetary rolling elements arranged between the inner ring and the outer ring, the planetary rolling elements each including a third set of teeth configured to engage with the first set of teeth and the second set of teeth, wherein a distance between adjacent teeth of a selected set of the first, second, or third sets of teeth is non-uniform, wherein the distance between adjacent teeth increases continuously between a first tooth and a last tooth of the selected set of the first, second, or third sets of teeth. 5. A planetary roller bearing comprising: an outer ring including a first set of teeth, an inner ring including a second set of teeth, and planetary rolling elements arranged between the inner ring and the outer ring, the planetary rolling elements each including a third set of teeth configured to engage with the first set of teeth and the second set of teeth, wherein a distance between adjacent teeth of a selected set of the first, second, or third sets of teeth is non-uniform, wherein the distance between adjacent teeth is constant after multiple increases. 6. A planetary roller bearing comprising: an outer ring including a first set of teeth, an inner ring including a second set of teeth, and planetary rolling elements arranged between the outer ring and the inner ring, the planetary rolling elements each including a third set of teeth configured to engage with the first set of teeth and the second set of teeth, wherein a height of at least three successive teeth from both axial ends of a selected set of the first, second, or third sets of teeth gradually increases. 7. The planetary roller bearing according to claim 6 , wherein a height of each tooth after the at least three successive teeth is constant.
