Description

Technical Field

[0001] The present application relates to the technical field of mechanical detection, in particular to multi-model magnetic particle motor dynamometers. Background Art

[0002] Gearboxes are widely used in major mechanical industries, such as the vehicle industry or motor equipment. There are multiple gears in the gearbox. Through the meshing and coaxial arrangement of the gears with each other, the input power is adjusted accordingly, so that the output power can be within a certain range, and then the output power can be used by people. After the gearbox is produced, relevant inspections need to be carried out on the gearbox to ensure the production effect of the gearbox.

[0003] In the related art, an operator needs to fix the gearbox to a support frame, connect the output end and the driving end of the gearbox, and judge the torque generated at the output end, so as to obtain relevant experimental data of the gearbox, which is convenient for the operator to judge whether the gearbox meets the relevant requirements.

[0004] In view of the above related art, when an operator needs to judge multiple types of gearboxes, different mounting brackets are required to fix the gearboxes. Therefore, the operator needs to continuously install new fixing brackets, which increases the working intensity of the operator. Utility Model Content

[0005] In order to facilitate the operator to perform relevant inspections on multiple gearboxes, the present application provides a multi-model magnetic particle motor dynamometer.

[0006] The present application provides a multi-model magnetic particle motor dynamometer, adopting the following technical solutions:

[0007] The multi-model magnetic particle motor dynamometer includes a workbench, a bottom plate and a testing device. The bottom plate is installed on the workbench, and the bottom plate can slide along the workbench.

[0008] The testing device includes a driving motor, a first dynamic torque sensor, a mounting plate, a gearbox, a second dynamic torque sensor and a coupling.

[0009] The driving motor is installed on the bottom plate. The driving motor is connected to the first dynamic torque sensor. Both ends of the gearbox are respectively connected to the first dynamic torque sensor and the second dynamic torque sensor. The second dynamic torque sensor is connected to a magnetic powder brake through the coupling.

[0010] The mounting plate is slidably connected to the bottom plate. The mounting plate is provided with a mounting groove. A limiting ring is arranged in the inner cavity of the mounting groove. The gearbox passes through the mounting groove and abuts against the limiting ring.

[0011] By adopting the above technical solution, when an operator installs the gearbox, the operator only needs to pass the gearbox through the installation slot of the mounting plate, and then install the driving motor and the first dynamic torque sensor at the input end of the gearbox. The second dynamic torque sensor, the coupling and the magnetic particle brake are connected to the output side of the gearbox. At this time, the first dynamic torque sensor determines the input torque of the driving motor, and then through the transmission of the gearbox, the second dynamic torque sensor determines the output torque of the gearbox. When the operator replaces different gearboxes, the operator only needs to disconnect the input end and the output end of the gearbox, and at the same time pass the gearbox into the installation slot of the mounting plate and make the gearbox abut against the limiting ring. Then, the operator adjusts the height of the driving motor and the position of the mounting plate to connect the gearbox, the first dynamic torque sensor and the second dynamic torque sensor, thereby completing the fixation of the gearbox, effectively improving the speed of the operator in fixing the gearbox, and improving the work efficiency of the operator and the overall applicability of the device.

[0014] Optionally, a universal joint is provided between the gearbox and the first dynamic torque sensor. One end of the universal joint is connected to the first dynamic torque sensor, and the other end is connected to the gearbox.

[0015] By adopting the above technical solution, the setting of the universal joint can correct the displacement difference between the axes of the first dynamic torque sensor and the gearbox, enabling the driving motor to transmit the torque to the input end of the gearbox and reducing the loss of torque during the transmission process.

[0016] Optionally, a speed reducer is provided between the gearbox and the second dynamic torque sensor. One end of the speed reducer is connected to the gearbox, and the other end is connected to the second dynamic torque sensor.

[0017] By adopting the above technical solution, the setting of the speed reducer can amplify the torque output from the output end of the gearbox by a certain ratio, and transmit the amplified torque to the second dynamic torque sensor, and the second dynamic torque sensor makes corresponding judgments on the torque.

[0020] By adopting the above technical solution, the support plate is installed on the bottom plate, and at the same time, the support plate can serve as the installation support for the driving motor. The operator can adjust the position of the lifting rod, and then complete the adjustment of the angle and height of the support plate, so that the angle of the output shaft of the driving motor changes, and thus the power output to different gearboxes can be improved.

[0022] By adopting the above technical solution, the fixed part and the movable part can enclose a protection area, thereby providing protection for the driving motor and the first dynamic torque sensor, preventing the operator from accidentally touching the driving motor and posing a threat to physical health.

[0023] Optionally, the testing device further includes a noise meter, and the noise meter is installed on the bottom plate.

[0024] By adopting the above technical solution, the noise meter can detect the noise during the device detection process, and then confirm the normal operation of the relevant structures inside the gearbox and the normal meshing of the relevant gears.
