Oil cooling motor cooling oil circuit structure

Abstract

The utility model discloses an oil cooling motor cooling oil circuit structure belongs to oil cooling motor field mainly solves the oil cooling scheme of prior art far from heat generating component, and the problem of low cooling efficiency, and the device includes the oil channel of setting on the casing, the rotating shaft, the stator core still includes the busbar of cooperation with stator core and forms the assembly of stator core core length section, sealing end plate, is equipped with the oil channel via hole of oil channel intercommunication on sealing end plate with the stator core, the busbar is designed with a plurality of radial extension's strip -shaped guide slot on the end face of stator core adhesion, and the corresponding through oil channel, is equipped with a plurality of oil grooves of going through in front and back on the outer cylindrical surface of busbar, and the oil groove is connected with strip -shaped guide slot. The busbar design can guarantee in any extreme case, and oil pump rotating speed can be reliably cooled down under all, and the sealing design of the complicated high -cost of the crown end outgoing line, the welding end oil immersion has guaranteed the optimal cooling, and also avoided the complicated high -cost sealing design of outgoing line end oil immersion.
