Abstract
Official abstract text for this publication.
The present invention proposes a deep groove ball bearing, having an outer ring, an inner ring, spherical rollers located between the inner ring and outer ring, and a cage for holding the spherical rollers. In an axial direction, the inner ring has a first inner ring shoulder at a first side, and a second inner ring shoulder at a second side opposite the first side; and a first inner ring shoulder diameter of the first inner ring shoulder is configured to be larger than a second inner ring shoulder diameter of the second inner ring shoulder. The present invention further proposes a differential including the deep groove ball bearing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A deep groove ball bearing, comprising: an outer ring, an inner ring, spherical rollers located between the inner ring and outer ring, and a cage for holding the spherical rollers, wherein in an axial direction, the inner ring has a first inner ring shoulder at a first side, and a second inner ring shoulder at a second side opposite the first side, and wherein a first inner ring shoulder diameter of the first inner ring shoulder is configured to be larger than a second inner ring shoulder diameter of the second inner ring shoulder, wherein the second inner ring shoulder diameter IRSD2, an inner ring raceway groove bottom diameter IRRD of the inner ring and the diameter RBD of the spherical rollers satisfy the following relation (1): ( IRSD 2 - IRRD ) R B D ≥ 0 . 2 5 , and ( 1 ) the first inner ring shoulder diameter IRSD1, the second inner ring shoulder diameter IRSD2 and the diameter RBD of the spherical rollers satisfy the following relation (2): ( IRSD1 - IRSD 2 ) R B D ≥ 0 . 0 5 . ( 2 ) 2. The deep groove ball bearing according to claim 1 , wherein a transitional part between the inner ring raceway and the first inner ring shoulder is chamfered or rounded; and/or a transitional part between the inner ring raceway and the second inner ring shoulder is chamfered or rounded. 3. The deep groove ball bearing according to claim 1 , further comprising a bearing sealing structure arranged between the outer ring and the inner ring, so that the interior of the deep groove ball bearing is sealed with respect to the outside. 4. A differential comprising: a differential shaft, and the deep groove ball bearing according to claim 1 , wherein the deep groove ball bearing is mounted on the differential shaft. 5. A deep groove ball bearing, comprising: an outer ring, an inner ring, spherical rollers located between the inner ring and outer ring, and a cage for holding the spherical rollers, wherein in an axial direction, the inner ring has a first inner ring shoulder at a first side, and a second inner ring shoulder at a second side opposite the first side, and wherein a first inner ring shoulder diameter of the first inner ring shoulder is configured to be larger than a second inner ring shoulder diameter of the second inner ring shoulder, wherein the second inner ring shoulder diameter IRSD2, an inner ring raceway groove bottom diameter IRRD of the inner ring and the diameter RBD of the spherical rollers satisfy the following relation (1): ( IRSD 2 - IRRD ) R B D ≥ 0 . 2 5 , and ( 1 ) the first inner ring shoulder diameter IRSD1, the second inner ring shoulder diameter IRSD2 and the diameter RBD of the spherical rollers satisfy the following relation (3): ( IRSD1 - IRSD 2 ) R B D ≥ 0 . 1 . ( 3 )
