Research Status and Countermeasure of Temperature Rise of Hydraulic Dynamic and Static Bearing

Abstract

Hydraulic dynamic and static bearing has the advantages of hydraulic pressure bearing and liquid hydrostatic bearing, with the peculiarities of higher load capacity, smallest oil film thickness, higher stiffness, and lower power and so on. It was suitable for not only high-speed precision spindle bearing but also low-speed heavy bearing. Because of the loading traits, ball mill will have a greater impact on the role of bearing, leading to the increasing temperature of bearing. The designers take many measures to reduce the temperature, but there are hardly any reports about mechanism of the increasing temperature. According to the study about the present situation and the research strategies of increasing temperature of dynamic and static bearing in the extreme conditions, this article explores the questions of the increasing temperature of dynamic and static bearing in the extreme conditions and the scarcity of this question at present, and proposes the mechanism and the research strategies of the questions of the increasing temperature of dynamic and static bearing of ball mill in the extreme conditions.
