Optimization Design and Research of Split Camshaft Ball Bearing Seat
In order to maximize the friction reduction benefits of camshaft ball bearings,the structural design of the split type bearing seat was optimized.CAE and process testing methods were used to verify the deforma-tion of the ball bearing,the fit clearance between the upper and lower covers of the bearing seat,and the dynamic torque of the camshaft.The results show that the interference between the bearing seat and the outer ring of the ball bearing,the position of the fixing bolts of the bearing seat,and the stiffness of the bearing seat have a sig-nificant impact on the friction reduction benefits of the ball bearing.The optimized split type bearing seat struc-ture can significantly reduce the deformation of the outer ring of the ball bearing,reduce the fitting clearance be-tween the upper and lower covers of the bearing seat,thereby reducing the internal clamping effect of the ball bearing and improving the benefits of rolling friction reduction.
