Factors affecting the carrying capacity of swing support

There are two forms of failure of the swing support, one is the raceway damage, the other is broken teeth, and the proportion of raceway damage is more than 98%, so we say that the mass of the raceway is the core problem of the quality of the swing support, affecting the quality of the swing support raceway more factors, including the raceway fire hardness, hardening layer depth, hardening layer depth, The radius of the raceway curvature and contact angle are undoubtedly the four most important factors, which affect the mass of the raceway in different ways and determine the carrying capacity and service life of the swing support.
