Basic performance requirements for piston shafts
Sep 29, 2018

The piston shaft is mainly made of high-quality 45# steel. During the processing, the surface of the product is specially ground and hard chrome plating technology, and then mirror polished. Therefore, the piston shaft has certain wear resistance and corrosion resistance, and is suitable for various cylinders, cylinders, piston rods, packaging, woodworking, textile, printing and dyeing machinery, die casting machines, injection molding machines, and other mechanical guides, ejector pins, etc. .


In these different applications, the piston shaft plays a very important role, especially when used as a cylinder, cylinder motion actuator, it belongs to a moving part with high movement and high technical requirements. In general, its main function is to connect the piston and the crosshead, transmit the force acting on the piston and drive the piston to move.


The basic performance requirements of the piston shaft are: 1. Sufficient strength, stiffness and stability; 2. Excellent wear resistance, high machining accuracy and surface roughness; 3. Minimize stress concentration in the structure. Impact; 4, to ensure reliable connection, to prevent loose; 5, the design of the piston shaft structure should facilitate the disassembly and assembly of the piston.
