Problems solved by technology
[0002] The existing engine hydraulic pump gear is mainly supported by the inner diameter of the gear bearing, and the spline end of the gear is generally a suspended structure. This structure makes the gear unstable when transmitting power, and it is easy to generate noise and vibration. After the engine has been used for a long time, it needs Disassemble the engine for maintenance, resulting in an increase in maintenance and use costs

The invention discloses a reliable hydraulic pump supporting structure which comprises a shell, a fixed shaft, a transmission shaft, a cover plate, a flange, a cylindrical roller bearing and a self-aligning roller bearing. A fixed shaft mounting position is arranged at the right end of the shell; the fixed shaft is fixed on the fixed shaft mounting position at the right end of the shell; transmission teeth are arranged on the outer side of the right part of the transmission shaft, and a spline is arranged on the inner side of the left part of the transmission shaft; the cover plate is connected with the shell; first bearing mounting positions are arranged on the inner side of the right part of the transmission shaft and the outer side of the left part of the fixed shaft respectively, and the cylindrical roller bearing is mounted in the first bearing mounting positions; second bearing mounting positions are arranged on the outer side of the left part of the transmission shaft and the inner side of the cover plate respectively, and the self-aligning roller bearing is installed in the second bearing installation positions; a bearing limiting end is arranged at the right end of the flange; and the flange is connected with the cover plate. The structure has the advantages of stable power transmission, low noise and long service life.
Description
technical field [0001] The invention relates to the field of engines, in particular to a reliable hydraulic pump support structure. Background technique [0002] The existing engine hydraulic pump gear is mainly supported by the inner diameter of the gear bearing, and the spline end of the gear is generally a suspended structure. This structure makes the gear unstable when transmitting power, and it is easy to generate noise and vibration. After the engine has been used for a long time, it needs Disassemble the engine for maintenance, resulting in increased maintenance and use costs. [0003] The disclosure of the above background technical content is only used to assist in understanding the inventive concepts and technical solutions of the present invention, and it does not necessarily belong to the prior art of this patent application. There is no clear evidence that the above content has been disclosed on the filing date of this patent application. Under the circumstance...
