、溶接作業そのものは容易ではない。Conventionally, welding has been used to connect the stator core of the motor to the front and rear housings, regardless of whether the motor is small, medium, or large. However, welding causes thermal deformation and the welding process itself is not easy.

後のハウジングとステータコアとを締結している。Therefore, recently, a fastening method using through bolts has been increasingly used. In that case, in the assembly process of fastening the stator core and the front and rear housings, a through pin is inserted into the hole in the stator core for inserting the through bolt, and the through pin is temporarily held in a jig at both ends of the stator core. By doing so, the stator core is temporarily fixed, and the winding work is performed in this state. After the work is completed, the through pin is pulled out and a through bolt is inserted in its place to fasten the front and rear housings and the stator core.

結方法は採用されていなかった。However, the above-mentioned fastening method using through bolts is not suitable for small (
For medium-sized motors, the length of the through pin is short;
Since it is light in weight, it is easy to insert it and pull it out after work, but in large motors, such as motors that weigh more than 400 kg, the through pins are long and the weight is also large, making it difficult to handle them. Therefore, the fastening method using through bolts was not adopted.

The present invention provides a fastening structure between a stator core and a front and rear housing, characterized in that the front and rear housings are fastened together by a screw member that is passed through a through hole in the front and rear housings and screwed into a thread of the through pin.

なる。The through pin used in the fastening structure of the present invention that screws the stator core and the front and rear housings is used to hold the stator core against the jig when winding the stator core in the assembly process of the motor having the fastening structure of the present invention. It is inserted into a through hole for the purpose of temporary fixing, and becomes an element member that achieves a fastening structure as a means for screwing together the front and rear housings without being removed even after the winding work is completed.

を有することとなる。The present invention will be described in more detail below based on embodiments shown in the accompanying drawings. The stator core 10 of the motor is constructed by laminating a plurality (many numbers) of annular element plates 40. Holes are provided near the outer periphery of each annular element plate IO at the same radial position so as to form a through hole 42 when stacked to form a stator core IO. Each annular element plate 10 is provided with a plurality of holes (for example, four holes) arranged at equal angles in the circumferential direction. Therefore, the stator core 10 has a plurality of through holes 42 parallel to the rotation center axis 44 of the motor.

During this winding work, the stator core 10 must be temporarily fixed. Therefore, the through hole 4 of the stator core 10
A through pin 20, which is longer than the length of the stator core 10, is passed through the stator core 10, and both ends of the through pin 20 are held by an appropriate jig. At both ends of the through pin 20, internal threads 24 are provided which can be screwed into bolts 30, which will be described later. When the winding work is completed, the stator core 10 is removed from the jig, but the through pin 20 is not removed from the through hole 42. At the front end and rear end of this stator core 10,
A bolt 3 (described later) is placed at a position corresponding to the position of the through hole 42.
The front housing 16 and the rear housing 18, each provided with a through hole 26 or 28 for passing the zero, are fastened together using bolts 30. These bolts 30 are screwed together and fastened with internal threads 24 provided at both ends of the above-mentioned through pin 20.
