The invention discloses a heavy-load drive axle of a 5-ton loader, which is characterized in that a 32222 bearing is adopted as a wheel side bearing, a split structure is adopted as a cross axle of adifferential mechanism, and the axle diameter is phi 34; the parameters of a wheel-side gear are as follows: the modulus is 6.5, center distance is 108.5, the pressure angle is 24 degrees, the addendum coefficient of planet gears and an inner gear ring is 1, the top clearance coefficient of the planet gears and the inner gear ring is 0.25, the addendum coefficient of a sun gear is 0.8, the addendum coefficient of the sun gear is 0.3, the tooth width is 70, the tooth number of the sun gear is 15, the modification coefficient of the sun gear is 0.15, the tooth number of the planet gears is 18, the modification coefficient of the planet gears is 0.1, the tooth number of the inner gear ring is 51, the modification coefficient of the inner gear ring is 0.3, and the number of the planet gears is3; the parameters of the differential mechanism are as follows: the tooth number of a bevel gear is 10, the tooth number of ta half axle gear is 16, the modulus is 9, and the pressure angle is 22.5 degrees. The safety reliability of the drive axle is improved, the service life of the drive axle is prolonged, and meanwhile the machining requirement of the cross axle of the split structure is lowered.

    本发明公开了一种5吨装载机重载驱动桥,其轮边轴承采用32222轴承,其差速器的十字轴采用分体式结构,轴径为Φ34;其轮边齿轮参数为模数6.5、中心距108.5、压力角24°、行星轮和内齿圈的齿顶高系数1、行星轮和内齿圈的顶系系数0.25、太阳轮的齿顶高系数0.8、太阳轮的顶系系数0.3、齿宽70、太阳轮的齿数15、太阳轮的变位系数0.15、行星轮的齿数18、行星轮的变位系数0.1、内齿圈的齿数51、内齿圈的变位系数0.3,行星轮的个数为3个;差速器参数为锥齿轮的齿数10、半轴齿轮的齿数16、模数9、压力角22.5°。本发明在提高驱动桥的安全可靠性和使用寿命的同时,还降低了分体式结构十字轴的加工要求。
