The most important executive component in the four mechanical engineering of the swing cylinder, and the main factor affecting its quality is the supporting bushing material. The following specifically introduces how to affect the quality of the swing cylinder.
The support bush is set in the groove of the inner diameter of the guide bush to guide and support the piston rod. The optimal design clearance between the inner diameter and the outer diameter of the piston rod is 0.08-0.16mm. When it is less than 0.08mm, the piston rod has a large resistance to movement, the cylinder trembles, and the bearing bushes wear quickly. In severe cases, there are abnormal sounds and the bearing function is lost. When the force is applied, the oil cylinder leaks, and the piston rod has oil.
The outer diameter of the support bush is in contact with the inner diameter of the cylinder barrel, and the optimal design clearance is 0.1-0.19mm. When it is less than 0.1mm, the resistance of the piston rod increases, and it cannot keep moving at a constant speed, which is more obvious when the oil temperature is high. The bushing can't support it. The baffle on the piston rod or the outer edge of the piston can easily scratch the inner wall of the cylinder barrel, which will cause the cylinder barrel to be scrapped in severe cases.
The above is the introduction of the factors that affect the quality of the swing cylinder, I hope to help everyone.
