The structure and working principle of mechanical contact rodless cylinder

Mechanical contact rodless cylinder, its structure is shown in the figure below. There is a groove in the axial direction of the cylinder tube, and the piston and slider move in the upper part of the groove. In order to prevent leakage and dustproof needs, polyurethane sealing tapes and dustproof stainless steel tapes are used at the opening to be fixed on the cylinder heads at both ends. The piston frame passes through the groove to integrate the piston and the slider. The piston and the slider are connected together to drive the actuator fixed on the slider to achieve reciprocating motion.

This kindThe characteristics of the cylinder are: 1) Compared with ordinary cylinders, the installation position can be reduced by 1/2 under the same stroke;2) No anti-rotation mechanism is required;3) Suitable for bore diameter 10~80mm, the maximum stroke can reach 7m when the bore diameter is ≥40mm;4) High speed, the standard type can reach 0.1~0.5m/s;the high-speed type can reach 0.3~3.0m/s. Its disadvantages are: 1) Poor sealing performance and prone to external leakage. When using a three-position valve, the medium-pressure type must be selected;2) The load force is small. In order to increase the load capacity, a guide mechanism must be added.
