摩擦压力机借助旋转元盘压在飞轮轮缘上的摩擦力作用,驱使飞轮旋转,并使滑块实现往复运动。目前,对摩擦压力机的各种计算方法所以不同,关键在于如何计算元盘对飞轮摩擦力的水平分量和垂直分量。按苏联吉明的分析,作用在飞轮上的摩擦力的合力与水平面的夹角β=45°,所以其水平分力和垂直分力都等于动滑动摩擦系数μ乘以正压力P_x;扎列斯基则认为β角从90°变化到0°,摩擦力的水平与垂直分量均为μ(P_x)/2;资料〔1〕中指出,摩擦力与水平面的夹角β很小,因此在分析与计算中,摩擦力的垂直分量f垂可略去不计,而水平分量
Friction press with rotating disk pressure on the flywheel flange friction, drive flywheel rotation, and the slider to achieve reciprocating motion. At present, the calculation method of the friction press is so different, the key lies in how to calculate the horizontal component and the vertical component of the friction disk of the flywheel. According to the analysis of the Soviet Union Jiming, the friction force acting on the flywheel is β = 45 ° with the horizontal plane, so the horizontal component and the vertical component are equal to the dynamic sliding friction coefficient μ times the positive pressure P_x; Zales The angle β is changed from 90 ° to 0 °, and the horizontal and vertical components of the friction are both μ (P_x) / 2. According to [1], it is pointed out that the angle β between the friction and the horizontal plane is very small. Therefore, With the calculation, the vertical component of friction f can be neglected, but the horizontal component
