Abstract
This application belongs to the field of engine assembly, and specifically relates to a loading control system for rotating parts in a semi-enclosed cavity, including a bearing system and a spring system. The spring system is connected within the bearing system, and can be pushed and pulled by moving the bearing system. The spring system includes a blind-hole shaft, a large spring, and a small spring. The small spring is coaxially connected to the blind hole of the blind-hole shaft, and the large spring is coaxially connected to the outer wall of the blind-hole shaft. One end of the large spring and the small spring are free ends, and the other end is a fixed end. The free and fixed ends of the large spring and the small spring are in the same direction. It is compact, lightweight, easy to operate, and has a simple structure and low processing cost. It can adapt to the axial force loading operation of rotating parts in a semi-enclosed cavity with small internal space, narrow exit, and low visibility. It can also be used in open spaces to replace similar but structurally complex equipment.
