Problems solved by technology

At present, there is a defect in this structure: after assembly, there is a certain assembly gap between the coarse filter and the gearbox housing, causing a small part of the transmission oil to flow into the oil passage through the gap, and then directly enter the control valve, In torque converters and hydraulic clutches, during transmission, impurities in the oil may cause abnormal wear of the friction plates of hydraulic transmission components such as control valves, which not only affects the filtering effect of the coarse filter, but also reduces the reliability of the gearbox.

Abstract

The invention provides a hydraulic coarse strainer structure for a crane gear box. The hydraulic coarse strainer structure comprises a filter element which comprises a cylindrical straining screen, and the filter element is inserted in a coarse strainer assembly cover. The hydraulic coarse strainer structure is characterized in that an O-shaped seal ring groove is arranged at the outer edge of the coarse strainer assembly cover. By means of the hydraulic coarse strainer structure for the crane gear box, transmission oil can be effectively prevented from flowing into hydraulic transmission elements of control valves and the like after assembly, and the utilization reliability of the gear box is improved.

Description

technical field [0001] The invention relates to a coarse filter for a hydraulic gearbox of a large-tonnage crane. Background technique [0002] The structure of the existing large tonnage crane hydraulic gearbox coarse filter is as follows: figure 1 As shown, the coarse filter 1 includes a filter element 2, and the filter element 2 includes a cylindrical filter screen 3 and an assembly cover 4 assembled with the gearbox housing. At present, there is a defect in this structure: after assembly, there is a certain assembly gap between the coarse filter and the gearbox housing, causing a small part of the transmission oil to flow into the oil passage through the gap, and then directly enter the control valve, In torque converters and hydraulic clutches, during transmission, impurities in the oil may cause abnormal wear of the friction plates of hydraulic transmission components such as control valves, which not only affects the filtering effect of the coarse filter, but also ...
