Abstract

The invention provides an oil-cooled electric driving system for testing. A shell is made of a transparent acrylic material. A first butt joint block is arranged on the side, facing the end cover, of the oil ring, a second butt joint block is arranged on the side, facing the oil ring, of the end cover and corresponds to the first butt joint block, and an elastic piece is arranged on the first butt joint block and / or the second butt joint block, so that the end cover and the oil ring are in elastic pressing fit. An oil plug on the shell is radially inserted into the first oil guide path and is connected with the second oil guide path, so that cooling oil in the first oil guide path cannot enter the windings at the two ends of the stator through the second oil guide path; the oil plug is radially and fixedly arranged on the outer side of the first oil guide path, so that cooling oil in the first oil guide path enters windings at the two ends of the stator through the second oil guide path, and the oil plug is used for realizing connection and disconnection of the oil path of the stator, so that oil throwing of the rotor is convenient to observe; and the strength of the shell is ensured through the pressing fit of the elastic piece.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an oil-cooled electric drive system for testing. 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 purpose of the present invention is to provide an oil-cooled electric drive system for testing tha...
