Document Type and Number:
WIPO Patent Application WO/2018/070062
Kind Code:
A1
Abstract:
An internally rotating gear pump P is configured such that a pinion 4 having external teeth 4a and a gear 5 having internal teeth 5a are housed in a casing 1, and the internal teeth 5a and the external teeth 5a are engaged with each other so as to cause rotation of the pinion 4 and the gear 5. The pinion 4 is linked to, and driven and rotated integrally with a rotary shaft 3 which receives a rotating force of an external motor, and serves as a driving gear that is rotated by means of driving of the rotary shaft 3. The gear 5 is rotatably supported by a gear pin 6 provided to the casing 1 via a gear bush 7 which is a slide bearing, and serves as a driven gear.
