三角皮带轮重量计算是机械零件设计中的一个重要环节,它除了求得材料消耗定额外,更重要的是作为飞轮用时,需要求出飞轮的转动惯量,用以求出转速变化时的能量变化值,因此必须尽可能准确地计算出带轮的重量。但由于带轮槽沟为一梯形截面圆环,其体积计算较复杂。为求出其体积,历来采用近似计算方法,即以梯形截面积乘以圆环中径之积来代替,但误差较大。为了较准确地求出其体积,有人采用分
V-belt pulley weight calculation is an important part in the design of mechanical parts. In addition to determining the material consumption, it is more important to use flywheel as the flywheel moment of inertia to find out the change of the energy value when the speed changes Therefore, the weight of the pulley must be calculated as accurately as possible. However, due to the pulley groove is a trapezoidal cross-section of the ring, the volume calculation is more complicated. To find its volume, the approximate calculation method has always been used, that is, the trapezoidal cross-sectional area multiplied by the product of the diameter of the ring instead, but the error is large. In order to more accurately find its volume, some people use points
