Eccentric copper bushing is one of the key components of cone crusher, and its formation principle is mainly based on the working principle of cone crusher.
When the cone crusher is working, the motor drives the pinion gear of the crusher, the pinion gear drives the big gear, the big gear assembly drives the eccentric bushing assembly and the main shaft assembly to center on the theoretical perpendicular line and rotate in the copper liner, and the main shaft assembly can realize the rotation with the centerline of the main shaft in the eccentric copper bushing.

In this process, the role of the eccentric copper bushing is to provide eccentric movement, so that the moving cone does eccentric swing in the crushing chamber, thus realizing the crushing of materials. Specifically, the inner surface of the eccentric copper sleeve and the outer column surface of the main shaft form a radial sliding bearing, when the eccentric copper bushing rotates, the main shaft will be driven by the eccentric copper bushing to do eccentric movement, so that the moving cone will do eccentric swing in the crushing cavity to realize the crushing of materials.
In a word, the formation principle of eccentric copper bushing is based on the working principle of cone crusher, by providing eccentric movement, so that the moving cone in the crushing cavity to do eccentric swing, so as to realize the crushing of materials.
