The strength calculation of shaft c

The strength calculation of shaft can be divided into three types: 1) according to the torsional strength or stiffness; 2) according to the combined strength of bending and torsion; 3) accurate strength check calculation.When the position of the supporting shaft and the load size, direction, action point and load type of the shaft have been determined, the supporting reaction and bending moment, the strength of the shaft can be calculated according to bending or combined bending and torsion forces. The load acting on a shaft is generally considered as a concentrated load. For example, in this design, the force of belt drive on shaft is taken at the midpoint of flange width. In the calculation, the axis is usually regarded as a beam with two fulcrums on the hinge support, and the fulcrum of the general axis is approximately taken as the midpoint of the width of the support. As the shaft used in this design is mainly affected by the bending strength, a small number of torsional strength is designed according to the torsional strength, and the bending strength of the shaft is checked. Firstly, the stress of the shaft is analyzed. The left end is subject to the gravity of the cone screen, the right end is the force of the wheel set shaft, and the middle is the two supporting forces of the bearing seat.The left end force includes the gravity of the screen itself, the gravity of the material and the centrifugal force caused by the rotation of the material. Therefore, when considering the force of the cone screen on the shaft, it is only an empirical data. Let's say that the solid cone sieve here is,
