The invention relates to a gearbox test condition adjusting device and method. The device comprises a control box, a PLC controller, a dial switch group, a point control switch group, an output wiring port group, an electromagnetic relay group and a power supply box. The dial switch group and the point control switch group are both connected with the PLC, and the function control switch group and the function switch are connected in series between the dial switch group and the point control switch group; the power supply box is connected with an output power supply end of the PLC controller, the dial switch group and the point control switch group are used for simulating a system start-stop switch and a gear selector, the output wiring port group comprises a digital quantity output wiring port and an analog quantity output wiring port, the digital quantity output wiring port is connected with a gearbox electromagnetic valve, the analog quantity output wiring port is connected with an eddy current loader, and the eddy current loader is connected with the PLC controller. An electromagnetic relay group is connected with a frequency converter of a driving motor, and the states of output signals are controlled through a PLC (Programmable Logic Controller), so that the test working condition of the gearbox is automatically adjusted.
Description
technical field [0001] The invention belongs to the technical field of gear box test process control, and in particular relates to a gear box test working condition adjustment device and method. Background technique [0002] For the adjustment of the working conditions of the gearbox test, the test operator usually adjusts the gearbox gear selector, the motor potentiometer and the loader potentiometer to achieve the required test conditions. For the test items with constant working conditions, this adjustment method can meet the requirements. Test requirements, but the current test conditions required by the HCQ300 marine gearbox require continuous reversing, variable speed and load change, and manual adjustment is difficult to achieve the required test conditions. Therefore, a device that can complete the adjustment of various test conditions is needed. Meet different test requirements. Contents of the invention [0003] In order to solve the above-mentioned technical pr...
