Abstract

At present, the traditional heavy-duty diesel engine main rotor and core shaft docking process solution has low precision, backwards supporting equipment, poor stability and other problems. In this paper, several solutions are proposed to address these problems, and two new designs are finally identified. Option A is to improve the accuracy of the main rotor-core shaft alignment by changing the placement of the rotor and core shaft, using telescopic hydraulic cylinders and adopting fixtures to fix them; option B uses 3D laser scanning technology, high-precision truss manipulators and "trap" type structural fixtures to solve the problem of inaccurate alignment between the keyway in the rotor cavity and the core shaft key and the inaccurate alignment between the rotor and the core shaft key. We also used 3D modelling and animation to solve the problems of the rotor core and core shaft shaking when the platform moves. We also simulated the working process of the two solutions through 3D modelling and animation. After comparison and analysis, both solutions can effectively achieve the automatic alignment of the rotor core and the core shaft key, ensure the coaxially of the rotor and the core shaft, and reduce the offset.
