て端面の仕上げ加工を施せばよい。Traditionally, rotors for vane pumps have complex shapes due to the need to form grooves for the vanes to pass through and internal cavities, so the manufacturing process involved casting using cores, which was extremely time-consuming and costly. The present invention solves the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings. 1 is a vane pump, and a pump 4 is rotatably supported in a case 2 by a shaft 3. . Grooves 5 are provided in the plate 4 at appropriate intervals, and vanes 6 are slidably inserted into the grooves 5. Also, groove 5
The manufacturing method 2 of the 0-theta 4, which has a hollow part 7 connected to the inner circumferential end, will be explained with reference to FIG. 5. A long material 40 is made by extrusion molding using a mold with a cavity 7.
After forming, theta 4 is completed by cutting into rounds according to the desired thickness (see the two-dot chain line). Note that the end face may be finished if necessary.
以上のように、本発明によれば、押出成型等でロータを
長尺材に形成し、かつ、輪切りにするだけで製作できる
ので、従来の鋳造に比べ、きわめて高能率かつ安価に提
供できる。As described above, according to the present invention, the rotor can be manufactured simply by forming the rotor into a long material by extrusion molding or the like and cutting it into rings, so it can be provided with extremely high efficiency and at low cost compared to conventional casting.
