Abstract

The invention provides a mounting and demounting tool and method special for a hydraulic axial plunger pump. According to the technical scheme, the mounting and demounting tool comprises a tubular operating rod, two sliders are arranged on the middle portion in the operating rod, two opposite ends of the two sliders are respectively connected with a telescoping mechanism, two notches are symmetrically formed in the lateral wall of the operating rod, a compressing mechanism is fixed on each of the two sliders, and the compressing mechanisms penetrate the notches and compress the operating rod. By the mounting and demounting tool which is simple in operation procedures and good in use effect, a hydraulic pump can be connected with or separated from a diesel engine fast.

Description

technical field [0001] The invention relates to a special disassembly tool and a disassembly method for a hydraulic axial piston pump. Background technique [0002] In order to further improve the product quality of hydraulic components, effectively ensure the performance and safety of each part of the hydraulic components in the working state and the working status of the entire main pump in the hydraulic system, it is necessary to conduct an actual installation test on the hydraulic pump. At present, domestic hydraulic parts manufacturers mostly use manual disassembly and assembly in the actual installation test process of hydraulic axial piston pumps. [0003] The hydraulic pump and the flywheel of the diesel engine are connected by a coupling. The coupling is generally a highly elastic anti-torsional vibration coupling. The installation angle of the pump. The mass of the main pump of an excavator above 20 tons is generally greater than 140kg, and it is difficult to adj...
