Sanya, hainan bearing manufacturer to introduce shaft failure forms and design criteria

Sanya, hainan bearing manufacturer to introduce shaft failure pattern and design standard 1. Shaft failure mode: there are mainly due to the lack of fatigue strength of fatigue fracture, due to a lack of strength of the plastic deformation or brittle fracture, wear, beyond the allowed range of deformation and vibration, etc. 2. The design of shaft should meet the following principles: ( 1) On the basis of working conditions of high temperature bearing, consumption quantity and economy yardstick, select the appropriate data, blank method and heat treatment method. ( 2) According to the stress of the shaft, the shaft parts unit location, coordination with the size and processing method of positioning way, the shaft detail request, sure axis reasonable structure shape and size, that is, stop the shaft structure design. ( 3) The strength calculation and checking. To force big long and thin axis ( Such as worm shaft) And to request high axial stiffness, and stop stiffness calculation. Work on the high speed shaft, due to risk of resonance, so it should stop vibration stability calculation.
