摘　　要：结合本公司全新开发的一款大扭矩、长寿命、高可靠性、铝合金壳体变速器,研究副变速器双列圆锥滚子轴承配合、游隙、预紧和寿命之间的联系,提出轴承结构的优化设计方案,计算各温度下轴承安装配合的游隙变化,利用传统方法和应力积分法对比分析轴承疲劳寿命,并获得了合理的轴承配合公差和定位预紧参数,最后其通过了轴承及变速器台架寿命试验验证。For an aluminum-alloy housed transmission newly developed by FAW with features of high torque, long service life and high reliability, we investigate the correlation between the fitting, clearance, preload and the life of subtransmission double-row tapered roller bearing, and put forward an optimum design solution of the bearing structure, and calculate the changes of bearing clearance under different temperatures. The bearing fatigue life is compared and analyzed by using the traditional and stress-integral method, the reasonable parameters for bearing fit tolerances and preload are obtained. The life of bearing and the whole transmission is validated by the bench test.
