Abstract

The invention provides a testing system and method for an oil-cooled electric driving system. Elastic parts are arranged on an oil ring and an end cover, so that the oil ring is matched with the end cover in an elastic pressing way, the compactness can be ensured, leakage can be prevented, the integrity of an acrylic shell and the 3D printing oil ring which are low in strength can be guaranteed, and damage caused by rigid connection in the prior art is prevented; an external driving part drives a rotor to rotate, and the rotor is not magnetized and does not participate in driving, so that the assembling difficulty of components such as the rotor and the stator can be reduced; when a stator oil way needs to be cut off, an oil plug is inserted into a first oil guide way in the radial direction and connected with a second oil guide way. when the stator oil path needs to be conducted, the oil plug is fixedly arranged in the outer side of the first oil guide way in the radial direction so as to meet the test requirement.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an oil-cooled electric drive system for testing and a testing method thereof. Background technique [0002] In the research and development stage of the electric drive system, it is necessary to verify the oil circuit of the electric drive system and observe the lubrication conditions of the stator, rotor, bearing and other components. At present, the technology generally adopts the same design of the aluminum shell prototype, and only replaces the material with transparent acrylic to achieve better observation results. However, due to the problems of low strength, temperature resistance, and low precision of the acrylic transparent shell, during the test process, Damage can easily occur and affect test results. Contents of the invention [0003] In order to overcome the above-mentioned technical defects, the object of the present invention is to provide an oil-cooled electric ...
