Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery and equipment, in particular to a novel hydraulic pump bracket. Background Art

[0002] In the field of mining machinery, internal combustion engines are still the main configuration mode as vehicle power. However, for the design and layout of mining machinery, since each functional module requires an independent power source, and in many cases this power source is a hydraulic pump, which is driven by an internal combustion engine, it is necessary to make full use of the number of power output ports of the internal combustion engine. In addition to the traditional diesel engine flywheel output, sometimes the front crankshaft end disc of the diesel engine is also used as a power output end. Unlike the flywheel housing, the front end of the crankshaft does not have a coaxial mounting fulcrum, so it is necessary to independently design a hydraulic pump mounting bracket to install the hydraulic pump and ensure the more precise concentricity of the hydraulic pump input shaft and the crankshaft.
