Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of motor end covers, and in particular relates to a rust-proof and corrosion-resistant front end cover of a motor. Background Art
[0002] The front end cover of the motor is an important accessory used in the motor. The existing front end cover of the motor is a metal accessory such as iron. The motor is often used in a relatively harsh environment. Due to the effects of moisture, high temperature, oxides, dust and other factors, the motor end cover is easily corroded, which not only affects the performance of the motor end cover, the motor operation is unstable, but also greatly reduces the performance of the motor end cover and other components.
[0003] The existing Chinese patent with the announcement number CN203086270U discloses a rust-proof motor end cover, including an end cover body and an ear plate. The end cover body and the ear plate are basically the same as the prior art. An ear plate with a through hole is welded to the periphery of the end cover body, and the ear plate is mainly used for connecting the end cover body with the motor; the outer surfaces of the end cover body and the ear plate are provided with a boiled black layer; and a layer of anti-rust paint is provided on the outer surface of the boiled black layer.
[0004] With respect to the above-mentioned related technologies, the inventors have found that there are at least the following problems in the technology: most of the existing technologies can only prevent rust on the outer surface of the front end cover of the motor. With long-term use, the surface of the front end cover of the motor is prone to rust, and it is necessary to regularly apply anti-rust oil to the outer surface of the front end cover of the motor. However, since there is also rust on the inner surface of the front end cover of the motor, but the inner surface of the front end cover of the motor is inside the motor, the front end cover of the motor needs to be disassembled, and it is troublesome to apply anti-rust oil, and there is a possibility that rust will occur if it is not applied for the sake of convenience. Utility Model Content
