The motor rotor expansion joint structure is characterized in that expansion joints are reserved among matching surfaces of the end rings and the guard rings, matching surfaces of the end rings and the balancing rings and matching surfaces of the guard rings and the balancing rings.
Description
Technical field
The utility model relates to motor manufacturing technology, particularly a kind of rotor expanded joint structure.
Background technology
At present, all be tight fit connection between gimbal, retaining ring and the end ring of end, rotor both sides, but gimbal, retaining ring and end ring are because function is different, and the material that adopts is different, during motor rotation, the thermal coefficient of expansion of gimbal, retaining ring and end ring is different, makes easily it extruding occur each other, cracks, perhaps generation is loosening comes off connected solder joint, thus the generation accident.
Summary of the invention
The purpose of this utility model is to provide a kind of rotor expanded joint structure, by introduce expanded joint structure between the cooperation of gimbal, retaining ring and end ring, has solved owing to the material difference causes being out of shape the problem that difference produces fault.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of rotor expanded joint structure, comprise rotating shaft, be set with rotor punching and bracing frame in the rotating shaft, be inserted with sliver in the rotor punching, the sliver end is provided with end ring, the end ring end is provided with gimbal, the outer circumference surface tight fit of the inner peripheral surface of described end ring and gimbal and bracing frame, end ring is set with retaining ring outward, described retaining ring is L-type, its minor face inserts in the groove of end ring and gimbal formation, it is characterized in that, is provided with the expansion joint between the mating surface of described end ring and retaining ring, end ring and gimbal, retaining ring and gimbal.
Characteristics of the present utility model and further the improvement are:
Form the first expansion joint between described end ring and gimbal, described the first expansion joint is the radial expansion seam.
Form the second expansion joint between described retaining ring and gimbal, described the second expansion joint is divided into radial component and axial component.
Described retaining ring is provided with little bulge loop, and end ring is provided with the little scrobicular ring corresponding with little bulge loop, forms the 3rd expansion joint between little bulge loop and little scrobicular ring, and described the 3rd expansion joint is divided into radial component and axial component.
Rotor expanded joint structure of the present utility model, comprise rotating shaft, be set with rotor punching and bracing frame in the rotating shaft, be inserted with sliver in the rotor punching, the sliver end is provided with end ring, the end ring end is provided with gimbal, the inner peripheral surface of described end ring and gimbal respectively with the outer circumference surface tight fit of bracing frame, end ring is set with retaining ring outward, described retaining ring is L-type, its minor face inserts in the groove of end ring and gimbal formation, it is characterized in that, is provided with the expansion joint between described end ring and retaining ring, end ring and gimbal, retaining ring and gimbal mating surface; In motor when operation,, the rotor end can produce temperature rise, causes the deflection of each parts different, can avoid the phenomenon such as cracking because solder joint that each part distortion amount difference is brought comes off and pushes but be provided with the expansion joint, can strengthen the stability of motor.
