Description

Technical Field

[0001] The utility model belongs to the field of motors, and in particular relates to a motor sealing structure and a motor. Background Art

[0002] Motors are used in almost all industries in modern society. Whether it is industry, agriculture, transportation or family life, motors are indispensable. The scope of use of motors is so wide that the requirements for their protection levels are also different. Since the motor realizes the conversion of electrical energy and mechanical energy, when the motor is in an open space, its own protection ability is particularly important. The motor is mainly composed of a motor mounting base (casing), stator and rotor cores, shafts, bearings, end covers and other components. The sealing protection of the motor mainly refers to the seal between the motor mounting base (casing) and the end cover.

[0003] The mounting base used in the existing motor installation is usually composed of two identical box-shaped metals, which are spliced ​​and installed by cooperating with multiple bolts to form an overall motor mounting base structure. However, with this method, the vibration generated by the motor will cause the bolts at the connection to loosen under long-term use of the motor, which will cause the seal inside the motor base to loosen, making it easy for external liquid to enter the motor base and cause corrosion to the motor. In addition, the motor mounting base will use more connecting materials and the cost will be higher. At the same time, the existing motor mounting base has poor sealing performance for the bearing at the internal output end. Under long-term rotation of the motor output end, the shaft sleeve that seals the bearing is prone to poor sealing, resulting in uneven rotation of the screw. Therefore, a motor sealing structure and a motor are proposed to solve the above problems. Utility Model Content
