运用摩擦学理论及弹性力学原理对向心球轴承滚珠及内圈(或外圈)的受力情况进行了系统的分析及研究,并提出一项可直接计算向心球轴承摩擦系致及摩擦阻力矩的理论公式。由该公式看出,向心球轴承摩擦系数不仅与轴承内外径差、滚珠-内圈(或外圈)的滑动摩擦系数以及滚珠数量等参数密切相关,而且还随轴承当量动载荷的变化而改变。 Based on the theory of tribology and the principle of elastic mechanics, the forces on the ball and the inner ring (or the outer ring) of the radial ball bearing are systematically analyzed and studied. A new method can be used to directly calculate the friction and friction of the radial ball bearing Resistance torque of the theoretical formula. The formula shows that the radial ball bearing friction coefficient is not only related to the bearing inner and outer diameter difference, the ball - the inner race (or outer race) of the sliding friction coefficient as well as the number of balls and other parameters are closely related, but also with the bearing equivalent dynamic load changes change.
