假设胶带输送机爬坡运行时的倾角为正角,下坡运行时的倾角为负角,则凸曲线是胶带输送机沿运行方向,倾角逐渐减小的过渡曲线。影响凸曲线的主要关系尺寸为:曲率半径R、侧托辊的成槽角φ_0、托辊间距1_t及曲线处托辊组数n。在确定凸曲线处的尺寸时,应考虑如下因素:(1)胶带侧边应变不超过容许值 (2)不致造成托辊轴承寿命的缩短 (3)不致因张力过大或成槽角过大造成胶 Assuming that the conveyor belt is inclined at a positive angle during hill-climbing operation and the inclination angle is a negative angle during downhill operation, the convex curve is a transition curve of the belt conveyor along the running direction and the inclination angle gradually decreases. The main relational dimensions that affect the convex curve are: radius of curvature R, flute angle φ_0 of the idler, idler spacing 1_t, and number n of idlers at the curve. The following factors should be taken into account when determining the size of the convex curve: (1) The strain at the side of the tape does not exceed the allowable value (2) It will not shorten the life of the roller bearing. (3) Cause glue
