Characteristics of gear rack meshing transmission
In fact, the combination of the tooth and gear is a special method. The sprocket bar is like a straightened and stretched one. This kind of transmission is not only a circular operation completed by itself, but also a form of force transmission through which it can run on the bar.
Maintenance of piston rod
The outer diameter difference of the piston rod can have a small gap on the circular diameter of the bearing, but under the precise movement, we can adjust the tolerance of the solid shaft, so that there will be no pressure and gap. If the roundness and straightness of the shaft are not good, pressurize the solid shaft periodically, which can not only reduce the service life, but also can not do linear movement. Therefore, we must pay attention to the selection. If the piston rod changes color, it means that the system has a high temperature.
How to choose the material of quenched and tempered piston rod
In order to increase the service time of the piston rod and reduce the wear of the piston rod, 38crmoalan alloy structural steel is selected as the blank.
What is the processing technology of piston rod?
The piston rod is produced by rolling, because the residual compressive stress in the surface layer is left in the surface layer, which is conducive to the closure of the micro cracks in the surface layer and hinders the development of sedimentation. In order to improve the surface corrosion resistance, the piston rod can slow down the fatigue crack or expansion, so as to improve the fatigue limit of the hydraulic cylinder rod. According to the rolling forming, a layer of cold work hardening layer is produced on the rolling surface layer, which reduces the ductility and plastic deformation of the cutting pair touching the surface layer, thus improving the wear resistance of the surface layer of the hydraulic cylinder rod and preventing the scald caused by cutting. After rolling, the reduction of roughness value can improve the matching characteristics. Together, the friction damage to the seal ring or hydraulic seal is reduced when the rod piston of the hydraulic cylinder moves, and the overall service life of the hydraulic cylinder is improved.
Precautions for installing piston rod
The piston rod is basically all the connecting parts which are often used in mechanical manufacturing. Therefore, we must attach great importance to its installation problems. Otherwise, if the installation is wrong, it will lead to the normal operation of machinery and equipment. So let's share the main problems to pay special attention to when installing the piston rod of the equipment.
Maintenance method of piston rod
Many processing plants need to use the piston rod, which needs maintenance after a period of time. However, many newcomers often do not know how to maintain the piston rod. Piston rod manufacturers share maintenance methods with you.
