The invention discloses a temperature-resistant and moisture-resistant rear end cover of a marine motor. The rear end cover comprises a stepped plate-shaped cover body, wherein a bearing hole is formed in the center of the cover body; a hollow cavity interlayer is arranged in the cover body; a water inlet joint and a water outlet joint are arranged on the outer wall of the cover body, and are communicated with the hollow cavity interlayer to form a cooling water channel; a further improvement is that the wall thicknesses of the bearing hole and the hollow cavity interlayer are uniform; a radial through hole which is communicated with the bearing hole is formed in the cover body and used for mounting a sensor. The temperature-resistant and moisture-resistant rear end cover is low in material consumption, low in manufacturing cost and good in cooling performance.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a rear end cover of a motor. Background technique [0002] The rear end cover of the existing motor is a solid disc structure. On the one hand, more materials are required for manufacturing, and the manufacturing cost is high. On the other hand, the heat dissipation performance is poor. of normal operation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a rear end cover for a marine motor with less material, low manufacturing cost and good heat dissipation performance. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The rear end cover of a temperature-resistant and humidity-resistant marine motor includes a stepped disc-shaped cover; the center of the cover is provided with a bearing hole; the improvement is that: the cover is provided with a cavity inter...
