m Q fiml-e 3. > Casing 2 consisting of L sea urchin casing body 2a and lid body 2b and a pair of gears 1
A pair of gears 1 meshed with each other were housed in a cavity 3 having a gourd-shaped cross section in a casing 2. Then, both side surfaces 4 of the gear 1 and both inner surfaces 5 of the casing 2 were brought into sliding contact, and the peripheral surface 6 of the casing was aligned with the tooth tips of the gear 1. In this gear rotary pump, when the gear 1 is driven to rotate in the direction of the arrow A, liquid is sucked in from the suction lower as shown by the arrow port, and liquid is discharged from the discharge port 8 as shown by the arrow C. In other words, suction is drawn between the teeth of gear 1 and the circumferential surface 6 of casing 2 as the suction lower rotates in the direction in which the pair of gears 1 open, and the rotation in the direction in which the pair of gears 1 closes through the discharge port 8. It is designed to be discharged by rotation of . In such a WIt gear rotary pump, the width of the gear 1 and the width of the cavity 3 of the casing 2 do not match, and as shown in FIG. If the gap S between them is large, there is a drawback that the self-priming force becomes small.

[Disclosure of the Invention] The gear rotary pump of the present invention has a pair of gears 1 that are meshed with each other internally in a casing 2, and the rotation of the pair of gears 1 causes liquid to flow from the suction lower of the casing 2 to the discharge port 8 of the casing 2. In the transmission device, the gear 1 and the casing 2 are made of synthetic resin, and the side surface 4 of the gear 1 to the gear 1
This is characterized in that one of the inner surfaces 5 of the casing 2 facing the side surface 4 of the casing 2 is made rough and coated with grease 10, and by configuring as described above, it is different from the conventional example. This solves the shortcomings.

In other words, by making one of the side surface 4 of the gear 1 to the inner surface 5 of the casing 2 a rough surface and applying the grease 10, the grease 10 is applied between the side surface 4 of the gear 1 and the inner surface 5 of the casing 2. As a result, a seal is formed between the side surface 4 of the gear 1 and the inner surface 5 of the casing 2 through the grease 10, thereby increasing the self-priming power and making it possible to maintain the self-priming power for a long period of time.
