Definitions
- FIG. 11 is a schematic cross-sectional view showing the trochoid pump of Example 9.
- the depth side end surface 13b of the stepped portion 13R and the front side end surface 1 lb of the inner rotor 11 come into contact with each other, and the first regulation It has a structure. Further, the front end surface 13a of the drive shaft 13 is configured to abut on the inner end surface 15a of the lid 15, and a second restricting structure is formed.
- the position of the drive shaft 13 in the thrust direction is determined with a simple configuration in which a part of the drive shaft 13 is a different diameter shaft 13X, even when the drive gear 17 is worn out. Since the offset amount of the drive shaft 13 does not change, the wear of the drive gear 17 increases. Can be prevented. Further, since the movable range of the drive shaft 13 can be adjusted by the trochoid pump 10 alone, the operability of the trochoid pump 10 can be improved.
- the front end surface 43a of the drive shaft 43 abuts against the inner end surface 45a of the lid 45 toward the front side in the thrust direction, thereby forming the second restriction structure.
- the depth side end surface 44b of the horseshoe-shaped piece 44 is regulated by the front side end surface 41b of the inner rotor 41 by applying a force toward the depth side in the thrust direction to form the first regulating structure. That is, the drive shaft 43 is regulated in the thrust direction.
- the trochoid pump 70 is provided with a cover 78 on which a drive gear 77 is mounted.
- the cover 78 is provided with a notch in a portion that comes into contact with a drive gear (not shown) to which the drive gear 77 transmits driving.
