Description

Technical Field

[0001] The utility model relates to the field of swing cylinders, and more specifically to a blade twisting swing cylinder system. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating or swinging motion. It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines, among which the blade swing cylinder is also a common one.

[0003] The utility model with authorization announcement number CN 209724834 U relates to the technical field of hydraulic cylinders, and in particular to a blade swing cylinder with good sealing performance and large torque. At present, the blades in the blade swing cylinder are clearance-matched with the inner wall of the cylinder body. While the hydraulic oil pushes the blades to rotate, part of the hydraulic oil will leak from the gap between the blades and the cylinder body, resulting in a pressure drop and a reduction in output torque. The utility model sets a reverse oil pipe joint 2 at one end of the blade rotating shaft 3 and communicates with the reverse axial oil inlet 32 ​​of the rotating shaft, and a forward oil pipe joint 7 is set at one end of the blade rotating shaft 3 and communicates with the forward axial oil inlet 33 of the rotating shaft. A thermal-sensitive sealing strip assembly 52 is provided at the end of the rotating blade 5, and the pressure of the hydraulic oil increases and generates heat when it flows through the blade.

[0004] In the above-mentioned disclosed structure, a structure with a fixed angle position is used to connect the blades, and there is a lack of a split combination structure to install the connecting shaft and the blades, which is not conducive to disassembly and maintenance. Moreover, after positioning, the blades cannot be twisted for balance adjustment, and the adaptability is poor, which needs to be improved. Utility Model Content
