摘要： PROBLEM TO BE SOLVED: To provide a 4-point contact ball bearing which is excellent in heat radiation and hardly brings seizure.
SOLUTION: The 4-point contact ball bearing is set so that the radius of curvature of the raceway groove 12 of the outer ring 2 is set to arrange in 55-56.5% as large as the ball diameter. In this way, slide between the balls 3 and the racingway groove 12 of the outer ring 2 becomes small and hence, the heat generation due to the slide is reduced and further, the gap 13 between the balls 3 and the raceway face 12 of the outer ring 2 gets large. Accordingly, the 4-point contact ball bearing is excellent in heat radiation and hardly brings seizure.

摘要： PROBLEM TO BE SOLVED: To provide a 4-point contact ball bearing which is excellent in heat radiation and hardly brings seizure and exfoliation.
SOLUTION: The radius of curvature of the raceway groove 11 of an inner ring 1 is set 50.5-53.5% as much as the ball diameter and the radius of cavature of the raceway groove 12 of the outer ring 2 is set 2-6% as larger as the diameter of the ball 3 than the radius of curvature of the raceway groove 11 of the inner ring 1. In this way, the plane pressure of the raceway groove 11 of the inner ring 1 is balanced with the plane pressure of the raceway groove 12 of the outer ring 2 to prevent decrease of the peeling life. Since the radius of cuvature of the raceway groove 12 of the outer ring 2 is larger than the radius of cuverture of the raceway groove 11 of the inner ring 1, slide between the balls 3 and the raceway groove 12 of the outer ring 2 gets small and heat radiation is reduced. And further, the gap 13 between the balls 3 and the track face 12 of the outer ring 2 becomes large and heat dissipation is improved and seizure hardly arises.

摘要翻译：要解决的问题：提供一种4点接触球轴承，其热辐射性优异，并且几乎不产生卡死和剥落。解决方案：将内圈1的滚道槽11的曲率半径设定为球直径的50.5-53.5％，将外圈2的滚道槽12的气蚀半径设定为2-6％，作为比内圈1的滚道槽11的曲率半径更大的球3的直径。以这种方式，内圈1的滚道槽11的平面压力与滚道的平面压力平衡外圈2的槽12，以防止剥离寿命的降低。由于外圈2的滚道槽12的圆弧的半径大于内圈1的滚道槽11的圆弧的半径，因此滚珠3与外圈2的滚道槽12之间的滑动变小并减少热辐射。此外，滚珠3和外圈2的轨迹面12之间的间隙13变大，散热得到改善，并且几乎不发生卡塞。
