The invention relates to a mounting and fixing device of a conducing ring in a motor, in particular to an adjustable fixing and supporting structure for the conducing ring of a motor stator, and solves the technical problems that the conventional conducing ring of the motor stator is supported not enough firmly and the axial mounting size cannot be guaranteed during mounting. The adjustable fixing and supporting structure for the conducing ring of the motor stator comprises a first supporting block and a second supporting block which are both made of insulating materials, wherein a groove is formed in the upper surface of the second supporting block along a center line in a length direction of the second supporting block; a pair of screw holes are formed in the bottom of the groove vertically, and arranged in a direction of the groove; the bottom of the first supporting block is embedded into the groove of the second supporting block; three conducing ring mounting grooves which are parallel to each other and arranged at equal intervals are formed in the upper part of the first supporting block vertically; the direction of each conducing ring mounting groove is perpendicular to that of the groove; adjusting bolts are arranged in the screw holes. The parts of the adjustable fixing and supporting structure, for the conducing ring of the motor stator, provided by the invention are simple in structure, so that the consistency and the stability for mounting the conducing ring axially are realized.
Description
technical field [0001] The invention relates to an installation and fixing device for a conductive ring in a motor, in particular to an adjustable supporting structure for fixing and supporting a conductive ring of a stator of a motor. Background technique [0002] The function of the conductive ring in the motor is to connect the pole phase groups of each phase in series into one circuit, or in parallel to form multiple circuits, so as to meet the different needs of the motor connection. Plays the role of input / output current in the motor. As the motor power continues to increase, the self-weight of the conductive ring continues to increase. In the limited space at the end of the inner cavity of the motor frame, how to realize the reliable fixing of the conductive ring and prevent the conductive ring from generating harmful vibration and causing electrical failure has become a key item in the design of the motor. [0003] Existing conductive ring support structures (such ...
