[0017] The utility model will be further described in detail below in combination with the drawings, and the technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment only is a part of the utility model embodiment, but is not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor all belong to the scope of the utility model protection.

[0018] As Figures 1-4As shown in the figure, a frame type oil channel casing for oil-cooled motor comprises a frame type casing 1 and a flange 2, two symmetrical processing ears 3 are arranged on the flange 2, two oil inlet holes 4 are arranged on the flange 2 at the positions of the processing ears 3, a plurality of longitudinal ribs 5 and a plurality of transverse ribs 6 are arranged on the inner wall of the frame type casing 1, the longitudinal ribs 5 and the transverse ribs 6 are staggered in the horizontal and vertical directions to form a plurality of square oil grooves 10, the side wall of the longitudinal rib 5 is provided with a transverse communication groove 8 for communicating the transversely adjacent oil grooves 10, and the side wall of the longitudinal rib 6 is provided with a longitudinal communication groove 9 for communicating the longitudinally adjacent oil grooves 10; the frame type casing 1 and the stator core are in interference fit, so that the plurality of oil grooves 10 in the interior are connected through the transverse communication groove 8 and the longitudinal communication groove 9 to form a frame type sealed oil channel.
