Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic motor detection and relates to a hydraulic motor component. Background Art

[0002] The hydraulic motor is an important actuator in the hydraulic system. Its main function is to convert the liquid pressure energy provided by the hydraulic pump into the mechanical energy of the output shaft (i.e. torque and speed). It is widely used in various mechanical equipment, such as engineering machinery, ships, metallurgical machinery, etc., to achieve the drive and motion control of the equipment. If the hydraulic motor cannot stably transmit the power during the power conversion process, a series of serious problems will occur.

[0031] See also Figure 1-Figure 4, as the first embodiment of the utility model: in order to solve the problem that unstable power transmission will cause the mechanical equipment to run unsteadily, or even cause shaking or vibration. This will not only affect the normal operation of the equipment, but may also damage the equipment structure and shorten its service life. First, the staff will introduce the pressure liquid through the inlet pipe 100 through the external equipment and export it from the outlet pipe 130. After the pressure liquid enters the hydraulic shell 110, a U-shaped flow direction is generated, and the hydraulic rotary vane 190 is driven to rotate by the pressure liquid. Since the inner side of the hydraulic rotary vane 190 is connected and fixed with the sealing seat 200 and the inner shaft rod 210, the rotation of the hydraulic rotary vane 190 drives the inner shaft rod 210 to rotate, and the rotation of the inner shaft rod 210 drives the driving gear to rotate.

At the same time, since a group of external fixing covers 180 for connection are provided on the front side of the shell, the external fixing covers 180 can effectively prevent external dust from entering the inner side of the three sets of planetary gears 230, thereby increasing the resistance of power transmission and reducing the power output efficiency.
