Abstract

The invention provides a heavy type gearbox oil flow test lubrication testing system. The heavy type gearbox oil flow test lubrication testing system is characterized by comprising an oil drip pan andan oil tank; a support for containing a test sample is arranged above the oil drip pan; the oil drip pan is provided with an oil outflow passageway and communicates with the oil tank; the system further comprises an oil outflow pipeline, the input end of the oil outflow pipeline communicates with the oil tank, and the output end of the oil outflow pipeline is located over the position where the test sample is put; and a gear pump, a heater, a heat exchanger, proportional valves, pressure sensors, a temperature sensor and a flow sensor are arranged on the oil outflow pipeline. The system aimsat the defects in the prior art, and the heavy type gearbox oil flow test lubrication testing system is provided to provide the strong data support for development, design and shaping of new products.

Description

technical field [0001] The invention relates to the field of gearbox testing, in particular to a lubrication testing system for heavy-duty gearbox oil flow test. Background technique [0002] At present, there are no comprehensive tests for the flow, pressure and temperature of the active lubrication system on the gearbox in various laboratories at home and abroad. The volume test method has large errors, low test result accuracy, and single function, which cannot meet the test requirements; the flow meter method currently has few tests for high and low temperature media, and cannot simulate different working conditions of the gearbox and lubricating oil under different working modes traffic requirements. The multi-functional and precise performance testing device for the lubrication system of the active part of the gearbox is at a blank stage in China. Contents of the invention [0003] The purpose of the present invention is to provide a heavy-duty gearbox oil flow tes...
