Abstract

The invention provides an oil-cooled electric driving system for testing. A shell is made of a transparent acrylic material; a driving part arranged outside the shell is included; one end or two ends of a rotor penetrate(s) through the shell, one end of a rotor is connected with the driving part, and the driving part drives the rotor to rotate; an oil plug of the shell is radially inserted into a first oil guide path and is connected with a second oil guide path, so that cooling oil in the first oil guide path cannot enter windings at the two ends of the stator through the second oil guide path; and an oil plug is radially and fixedly arranged in the outer side of the first oil guide path, so that cooling oil in the first oil guide path enters the windings at the two ends of the stator through the second oil guide path. The rotor is driven to rotate through the external driving part, and the rotor is not magnetized and does not participate in driving, so that the assembly difficulty can be reduced; and on-off of the stator oil path is realized through the oil plug, and the oil throwing of the rotor is convenient to observe.

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 object of the present invention is to provide an oil-cooled electric drive system for testing that...
