Abstract

The invention provides a hydraulic motor braking moment testing tool and system. The hydraulic motor braking moment testing tool comprises a supporting frame, a positioning frame supported on the supporting frame, and a circumferential positioning piece. The positioning frame is provided with a positioning hole, a hydraulic motor is supported on the positioning frame through the positioning hole,and the positioning frame can clamp the hydraulic motor in the axial direction of the hydraulic motor so as to limit the degree of axial freedom of the hydraulic motor; and the circumferential positioning piece is in inserted connection with the positioning frame, can move relative to the positioning frame, and is used for being in inserted connection with the hydraulic motor so as to limit the degree of circumferential freedom of the hydraulic motor.

Description

technical field [0001] The invention relates to the field of motor testing, in particular to a hydraulic motor braking torque testing tool and system. Background technique [0002] As an actuator of the hydraulic system, the hydraulic motor converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy of the output shaft of the hydraulic motor through the hydraulic motor, that is, the torque parameter and speed parameter of the output shaft of the hydraulic motor. Hydraulic motors are mainly used in construction machinery, ship machinery, mining machinery, port machinery and other fields. [0003] The inclined-axis hydraulic motor is one of them. The inclined-axis hydraulic motor is mainly used on medium-sized excavators. After the factory test, this type of motor needs to be tested for braking torque to ensure that the braking torque is greater than 620N. M, therefore, it is imperative to design a reliable tooling for fixing the motor and...
