The piston rod is a connecting member for supporting the work of the piston. It is often inseparable from the use of the piston, so the piston rod and the piston must be connected. use. The cylinder piston rod wear ring can improve the guiding of the cylinder, reduce the wear of the piston seal and reduce the frictional resistance. The hydraulic piston rod improves the surface corrosion resistance and can delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the cylinder rod. The 45# piston rod supports the connecting parts of the piston work. Most of them are used in the cylinder and cylinder movement executing parts. It is a moving part with frequent movement and high technical requirements. The 45# piston rod connects the piston and the crosshead to transmit the force acting on the piston and drive the piston to move. The hollow piston rod refers to a hollow piston rod having an annular cross section. So, do you know which way to connect the piston rod to the piston? Piston rod head connection method: The connection of the piston rod head mainly refers to the piston rod and external load (load) (Component) connection parts, the more common main connection structure forms are threaded and single earring type. When applied in actual work, it must be determined according to the actual working condition (Condition). The connection mode of the tail of the piston rod: the connection mode of the tail of the piston rod mainly refers to the connection part of the tail part of the piston rod and the piston, and has various structural forms, and the more prominent one is the form of the card-type connection structure. The card-type connection structure is easy to install and has better performance, so it has many applications. The connection method of the main body of the piston rod: the connection between the main body of the piston rod and the piston can be mainly divided into two types: a solid type and a hollow type (Condition). The solid type is often used in general cases, while the hollow type is often used for special requirements. For example, a piston rod in a hydraulic cylinder must be equipped with a transducer. Therefore, the solid piston rod can be mainly used in the case of a small rod diameter, and when the rod diameter is large, in order to reduce the heavy child, a hollow piston rod is generally used.
