Description
Technical field
The utility model relates to a kind of piston rod, in particular to a kind of logical empty piston rod.
Background technique
Piston rod is the connecting component of supporting piston acting, and major applications are in oil cylinder, cylinder moving execution unit
The moving component that one movement is frequent, technical requirements are high.Piston rod weight itself is that quality is bigger more again, and the inertia generated is just
Can be bigger, inertia, which gets over conference, keeps the Rubbing number between piston rod and the oil sealing of cylinder body more frequent, to greatly shorten piston
The service life of bar.
Utility model content
[1] technical problems to be solved
