Embodiment
[0071] Embodiment: the present invention collects the transmission oil of a certain oil change period in the transmission system of high-power engineering vehicles, and uses it in the confluence planetary row of the same type of transmission system, and continues to use it in the test bench experiment. The test method of the present invention is used to simulate the track Under different working conditions of the vehicle, monitor the oil pollution degree and energy consumption loss of the confluence planetary row, test the wear and failure status of the confluence planetary row, and set different working conditions to determine the energy consumption of the confluence planetary row under a certain pollution degree To observe and detect the degree of loss and wear, so as to choose and control the oil change interval of the vehicle.

The invention relates to a method and a device for testing oil liquid contamination tolerance in a wet-type clutch sliding and grinding process. The device comprises a power transmission loading system, wherein both the power transmission loading system and an oil liquid lubricating system are connected with a wet-type clutch case; the power transmission loading system, the oil liquid lubricatingsystem and the wet-type clutch case are all connected with a control and acquisition system; the power transmission loading system comprises a power motor; the output end of the power motor is connected with the input shaft of the wet-type clutch case; an input shaft rotation speed torque sensor is arranged at the output end of the power motor; the output shaft of the wet-type clutch case is connected with an electric eddy current dynamometer through a coupling; an output rotation speed torque sensor is arranged on the output shaft of the wet-type clutch case. By adopting the method and the device, the tolerance of a wet-type clutch at a high-speed rotation working state at different oil liquid contamination degrees can be tested, and with the combination of temperature measurement and consumption power analysis, the contamination tolerance of the wet type clutch can be judged.
Description
technical field [0001] The invention relates to the field of dynamic characteristic measurement of confluence planetary gears in a high-power construction machinery transmission system, in particular to a test method and device for oil pollution tolerance in a wet clutch sliding grinding process. Background technique [0002] Confluence planetary gear transmission has been widely used in various transmission systems. Whether it is in high-speed rotating machinery, or in many fields such as high-torque low-speed equipment, it has been widely promoted and adopted. According to statistics on the technical status of high-power construction machinery transmission equipment in use in recent years, the problems exposed mainly include the wear of bearings and gears caused by excessive pollution of system lubricating oil, severe wear of friction plates of shift clutches and lock-up clutches, Severe wear and tear may lead to the malfunction of the control parts and the loss of contro...
