This paper analyzes the reasons of jiaxing textile machinery bearings bearing damage source: this website the author: the administrator to release time: 2015 - 09 - 10 09:15:44 views: 0 analysis of jiaxing textile machinery bearings bearing damage because it is well known that in our life, the application of common bearing parts, the normal operation of general equipment without the installation of the bearing is used. Jiaxing textile machinery shaft is installed on the textile machinery bearings, the bearing parts used for a long time, there will be damaged, so what is the cause of this phenomenon? Now it's time to analysis the reason. Textile machinery processing quality by the manufacturing precision of the bearing itself, axial clearance, and the influence of heat treatment condition is very big, easy to overlook the factor is the influence of heat treatment condition. Obviously, to the raceway surface does not produce cracks and sag, requires the raceway surface except with sufficient rigidity and outside, still need to have enough depth of hardening layer and hardness. So in jiaxing textile machinery bearing raceway surface hardening layer depth is not enough, the core hardness is low, it is also one of the cause of the damage. Textile machinery bearings often operate under low speed and heavy load, the bearing capacity generally available static capacity, according to the rated static capacity for c0a. Static capacity refers to the race has been deformation delta reaches 3 d0/10000 carrying capacity of the textile machinery bearings, do as the roll diameter. Jiaxing needle roller bearing outer load combination with equivalent load Cd. The ratio of the static capacity and the equivalent load is called safety factor, notes for the fs, this is the design and choose the main basis of needle bearing. This article mainly analyses the case of damage of jiaxing textile machinery bearing all the specific reason, thus we know the affected by the manufacturing precision and heat treatment condition. And know the carrying capacity of the needle roller bearing is also different, choose the appropriate bearing products can obviously improve the equipment operation efficiency, choose jiaxing needle bearing it.
