1. Composition of connecting rod
The connecting rod body, universal joint assembly, Coupling rod, Guide Bush, rubber ring, rubber sheath, connecting rod pin, Retaining Sleeve, steel wire ring, drive shaft, etc.
2. The connecting rod group not only bears the force of the drive shaft, but also bears the action of its own oscillating longitudinal and transverse inertial forces. The magnitude and direction of these forces are periodically changed, so the connecting rod will be subjected to alternating loads such as compression and tension.
3. If the stiffness of the connecting rod is insufficient, it will cause bending deformation of the rod body and deformation of the Universal joint assembly, resulting in partial wear of the Coupling rod, Guide Bush, and long Bush.
