Abstract

Most thrust bearing group’s lubrication ways of screw drill are the drilling fluid lubrication. Abrasive wear and drilling fluid corrosion could happen easily on thrust bearing group in this lubrication way. Aiming at this problem, through analyzing the structure of traditional transmission shaft assembly and making sure the possible structure of causing leakage problems, the main structure affecting the oil lubrication way can be divided into three categories: screw joint structures, the clearance fit of relatively static and the relative rotating clearance fit. According to these three problems, a series of actions are taken to improve the transmission shaft assembly and these problems affecting the oil lubrication structure of bearing group’s come true, so as to realize the transformation of the bearing group’s lubrication from the drilling fluid to the oil storage.
