TEMPERATURE PREDICTION ON DEEP GROOVE BALL BEARING OF ROTARY CONTROL HEAD BASED ON GREY NEURAL NETWORK
Due to the center deviation among wellhead,rotary table and crown block,the deep groove ball bearing of rotary control head（ RCH） is affected by large lateral load. In the meantime,deep groove ball bearing can produce a large amount of heat because of the effect of friction torque,which is easy to c...
