The main failure form of the rotary liner hanger bearing is roller end breakage in the drilling engineering. Some modification methods are applied to solve this problem, however, the modification formula is very complex and calculation process need to be repeated, which may lead to calculating negligence, and lower the accuracy of modification. In this paper, one rotating liner hanger bearing roller modification system is designed by applying Solidworks API functions, macro and VBA programming environment based on Solidworks secondary development platform and improved roller modification theory of rotating liner hanger bearing roller. With analyzing the working condition parameters, designing the modeling program, and designing interface and the result display module, a parameterized modeling and rapid modification of tapered roller system is achieved. This system greatly improved the efficiency and accuracy of the modeling and modification of roller, which provides some convenience for the subsequent research, analysis and manufacturing.
