The invention relates to the technical field of diesel locomotives, in particular to a side bearing hole supporting mechanism of a diesel locomotive underframe. The side bearing hole supporting mechanism comprises a main beam, webs, a bottom plate and a side bearing hole. The webs and the bottom plate are connected to the side portions and bottom of the main beam respectively, the side bearing hole is formed in the bottom plate, the side bearing hole is in a drop shape, and a bearing stand plate, a supporting plate, a supporting ribs, reinforcing ribs and a reinforcing stand plate are arranged in the side bearing hole. The side bearing hole is formed in the position, on a lower cover plate of the main beam, of the bottom plate, a traditional frame loading and stress concentration area is avoided, the hole is designed to be in the drop shape, the hole has more excellent mechanical properties under the same thickness, stress is reduced, and the local safety coefficient is greatly improved. In addition, the size of the side bearing hole is obtained in a parameterization mode, the side bearing hole supporting mechanism is suitable for side bearing design of any frame hole, and great universality is achieved. The supporting plate is welded in a frame formed by combining the bearing stand plate, the webs and the bottom plate, and therefore the overall bearing strength of the side bearing hole is greatly improved, and safety is improved.
