Research on Casting Process of Roll Bearing Seat
Wall thickness of roller bearing seat with high size precision and special structure differs greatly from one point to another.There are UT crack detection requirements and other specific quality requirements in multiple points on bearing seat.The solidification feeding forming of the bearing seat is achieved and numbers of cast detects are avoided by patch,external chill,riser feeding,as well as reasonable design of cast system.Meanwhile,the success rate of UT detection and other detection is pretty high. It is also convenient for the following machining operation with excellent performance.In this paper,the design of process of the bearing seat has been presented.It mainly illuminates the effective setup of riser head,chill,and patch,as well as integrated application of the other process operation.
