In order to ensure that the hollow shaft can work normally under the specified life, it must be designed correctly for the above-mentioned failure modes. The main content of the hollow shaft design is:
(1) According to the working conditions of the hollow shaft, production batch and economic principles, select suitable materials, blank forms and heat treatment methods.
(2) Determine the hollow according to the specific requirements of the hollow shaft, the installation position of the parts on the hollow shaft, the matching size and positioning method, and the processing method of the hollow shaft. The reasonable structural shape and size of the shaft, namely the structural design of the hollow shaft.
(3) Calculation or verification of the strength of the hollow shaft. For slender hollow shafts with large forces (such as worm hollow shafts) and hollow shafts with high rigidity requirements (such as main hollow shafts of lathes), stiffness calculations are also required. For hollow shafts working at high speeds, due to the danger of resonance, vibration stability calculations should be carried out.
