【摘要】 十字轴 A- A截面最大应力为 877.5 4MPa,安全系数为 1.3。滑块式万向轴最薄弱处为轧辊侧叉头 ,最大应力为 2 82 .75 MPa,安全系数为 3.1,最大应力点位于轴向中心孔和虎口后部横向圆弧相贯处。利用原中间轴进行万向联轴器改造 ,用过盈联接传递较大扭矩方法 ,结构简单 ,不需要任何紧固件 ,联结定心自位好 ,承载能力高 ,承受交变和冲击载荷性能好 ,安全可靠。更多还原

【Abstract】 The maximum stress in A A section of cross axis is 877 54 MPa,safety coefficient is 1 3 The weakest part in sliding universal axis is the lateral fork,the maximum stress is 282 75 MPa,safety coefficient is 3 1 The maximum stress lies at the intersecting point between the central hole and horizontal arc behind the tiger’s mouth Original central axis is used for the reform of the universal coupling,through excessive connection to transmit torque,the structure is simple,does not need any tighten item,has good self centering property and strong loading capacity,good performance in bearing alternative,and impact load is safe and reliable更多还原
