The invention provides a closed hydraulic driving system and a crusher and relates to the technical field of pump-control-motor speed governing systems. The closed hydraulic driving system acts on a hydraulic motor and comprises a main pump loop driving subsystem, an oil supplement loop driving subsystem, a total cooling loop driving subsystem and a hydraulic oil tank. The main pump loop driving subsystem can drive hydraulic oil in the hydraulic oil tank through a variable displacement piston pump so as to drive the hydraulic motor to run. Furthermore, temperature of oil which returns to the hydraulic oil tank can be adjusted through the total cooling loop driving subsystem, and pressure control oil can be provided for the main pump loop driving subsystem through the oil supplement loop driving subsystem. The hydraulic driving system which is large in torsion, low in energy consumption and stable during driving and can easily achieve continuously variable transmission is achieved through the variable displacement piston pump, and the closed hydraulic driving system is more reasonable in structure and more suitable for being applied and popularized.
Description
technical field [0001] The invention relates to the technical field of pump-controlled motor speed regulation systems, in particular to a closed hydraulic drive system and a crusher. Background technique [0002] The hydraulic drive system of the crusher is mainly used to drive the cutter shaft of the crusher to rotate. [0003] The traditional open hydraulic system that uses a high-speed hydraulic motor to drive the reducer to drive the cutter shaft has the disadvantages of unreasonable structural design, large volume, large noise, large vibration impact, and high energy consumption, and will seriously affect the hydraulic station, reducer and The service life of the hydraulic motor and the heavy weight of the reducer make it inconvenient to install and disassemble, which is not conducive to popularization and use. Contents of the invention [0004] The purpose of the present invention is to provide a closed hydraulic drive system and a crusher, so as to alleviate the te...
