八、轴轴的损坏被当作是它的极限状态,这种损坏是一种无条件的偶然失效。扭矩和应力的计算是按以下假设进行的:不考虑质量和离心力,不考虑因轴向力而产生的拉压应力;啮合力是沿齿宽均匀分布的,在小齿轮和大齿轮的轮毂范围内扭转力矩是均匀分布的;从轮毂作用到轴上的横向载荷是以两个集中力的形式传递的,该力作用在距轮毂端面为0.2倍的轮毂宽度处;把轴心线与轴承外圈 Eight, shaft damage is considered as its ultimate state, this damage is an unconditional accidental failure. The calculation of torque and stress is based on the assumption that the mass and centrifugal forces are not taken into account irrespective of the tensile and compressive stresses due to the axial forces; the meshing forces are evenly distributed along the tooth width, The internal torsional moments are uniformly distributed; the transverse load acting from the hub to the shaft is transmitted in two concentrated forces acting at a hub width of 0.2 times the hub end face; ring
