该文对用牛顿不可压流体润滑的锥面螺旋槽推力轴承进行了理论分析,螺旋角、槽深、槽台对数等不等时,轴承的承载量亦不同.该文用有限元法计算厂轴承的膜压分布及承载量.“,”The conical spiral groove bearing lubricated with Newton incompressible liquid is investigated theoretically. Bearing with different spiral groove angle, groove depth and groove number have different load capacity. In this paper, a finite-element method is used to calculate pressure distribution and load capacity.
