Detailed Description
The present invention is discussed in further detail below in conjunction with fig. 1-6.
The utility model provides a fastening structure of stator in motor, include the fan-shaped stator unit 10 that constitutes together by the stack of multi-disc stator punching unit, the annular stator core that a plurality of fan-shaped stator units 10 concatenated formation each other, it is downthehole that the annular stator core is inlayed to support a section of thick bamboo 20 interference, offer porose or groove 11 on the fan-shaped stator unit 10, the length direction of hole groove 11 is parallel with the dabber direction of annular stator core, fastening cramp 30 passes in hole or the groove 11 and compresses tightly fan-shaped stator unit 10, bolt 40 fixes fastening cramp 30 on supporting a section of thick bamboo 20. Because the annular stator core is formed by mutually connecting the plurality of fan-shaped stator units 10 in series, the whole annular stator core is loose after being assembled, after the supporting cylinder 20 is embedded into the inner hole of the combined annular stator core in an interference manner, each fan-shaped stator unit 10 moves outwards in a radiation manner in a balanced manner under the interference effect of the supporting cylinder 20, the purpose of tensioning the fan-shaped stator units 10 by the supporting cylinder 20 is realized, then the fastening buckle pieces 30 penetrate through the fan-shaped stator units to be provided with holes or grooves 11 and compress the fan-shaped stator units, and the fastening buckle pieces 30 are fixed on the supporting cylinder 20 by bolts, so that the fastening of the stator core is realized. Meanwhile, the hole or the groove 11 for the fastening buckle piece 30 to pass through also forms a part of the internal circulation air passage, and the cooling structure in the motor is optimized.
Specifically, the fastening buckle piece 30 is shaped like a Chinese character 'ji', the middle piece 31 is pressed tightly on the wall of the hole or the groove 11, the end pieces 32 at the two ends are attached to the wall of the supporting cylinder 20, the end pieces 32 are provided with through holes 321, and the bolt 40 passes through the through holes 321 to be fixedly connected with the supporting cylinder 20. After the supporting cylinder 20 tightly stretches the fan-shaped stator units 10, the fastening buckle pieces 30 fix each fan-shaped stator unit 10 on the supporting cylinder 20, so that the stator core is fastened.
Furthermore, the reinforcing rib pieces 33 are arranged on the middle sheet body 31 of the fastening buckle piece 30, and the arrangement of the reinforcing rib pieces 33 not only increases the strength of the fastening buckle piece 30, but also increases the contact area between the stator core and the air inside the motor, and improves the cold zone circulation inside the motor; in order to ensure that the holes or the grooves 11 are smooth of the internal circulation air passage, the reinforcing rib pieces 33 are arranged perpendicular to the middle sheet body 31, the length of the reinforcing rib pieces 33 is consistent with that of the middle sheet body 31, and the width of the reinforcing rib pieces 33 is smaller than that of the holes or the grooves 11.
