Press and rub to the inner side wall of the delivery chamber to maintain the stability of the pump delivery liquid for a long time. [Prior Art] The conventional pumping system places the inflow hole and the discharge hole on the concave side of the casing cover of the conveying chamber. During the process of conveying the liquid, the inner rotating gear in the casing cover is pushed by the liquid to the outer gear. The inner side shafts are miscellaneous, but the internal temperature of the machine is increased, and the inner side wall and the outer gear (4) are continuously subjected to wear and voids. When the gap is enlarged, the liquid in the conveying chamber is caused by the gap. Returning to the manhole, eventually causing the pump to idle and unable to deliver liquid. As shown in FIG. 7, the conventional internal rotation gear pump presses the through hole A31 of the center of the inner rotation ω wheel A3 by a bushing A4, and the outer tooth of the conveying chamber is rotated by 10 by the motor belt to make the inner The toothed gear Α3 is rotated on the fixed shaft 镶2 of the casing cover 1 of the conveying chamber to pump the liquid in a manner of sealing the pumping chamber by 7G. However, since the bushing Α4 and the fixed shaft 八2 are not worn for a long time, during the rotation of the inner turning wheel and the liquid pumping, if the particulate solid material enters between the bushing Α4 and the fixed ferrule 2, it is easy to cause The wear of the bushing Α4 and the fixed shaft 加剧2 is intensified to create voids, and when the pores are large enough, the machine cannot transport the liquid. There are 4 dishes here, 4 to improve the above-mentioned shortcomings, so that the pump can reduce the friction and the loss of power and parts during the long-term operation, so as to effectively transport the liquid, and send it 5 200844329 Inspection _ gallbladder, 遂 [invention content] a generation.

In addition, the end of the driven gear $ φ is provided with an annular limiting groove 52 which is engaged with the stopping portion 421 of the shaft 42 , and one end of the shaft 42 and the inner circumference of the driven gear 5 are also A corresponding positioning groove (422, 53) is provided for a positioning key 423 to be placed therein. A radial opening 45 is provided above the body 4, and a bearing fixing device 6 is provided at the rear end of the cover 4. There are two bearings (43, 43,) and a stuffing box 44 in the cover body 4, and there is no sleeve-cut between the two bearings 43 for positioning the two bearings on the shaft a, and the The carrier 43 is fixed to the shaft 42 by the bearing fixing device 6. The surface 7 200844329 has a three-layered annular packing w and an annular adjusting bolt which is provided with a corresponding inner tooth on the inner side of the cover body, and the packing 441 is disposed in the flow guiding chamber 41. The rear side of the L-shaped plug 442 material is provided with an adjustment groove 443 at the periphery thereof, so that the adjusting screw k 442 can adjust the filler 441 to enter and fill the stuffing box by the radial opening 45, and the The filler 441 is pressed against the rear of the flow guiding chamber 41. Furthermore, the adjusting bolt 442 is further provided with a 〇-ring 432 and an oil seal 433. The bottom of the cover 4 further has a bolt 46 with a drain hole to prevent liquid from penetrating into the bearing from the through hole 411 (43, 43, )Inside. Using the %, the driving device 2 drives the active return wheel 34 in the transport chamber 31 to rotate in the counterclockwise direction via the output shaft 23, and drives the driven gear 5 to drive the liquid in the inflow hole 32 from the main wheel 34 and the slave. The backlash and the concave portion of the wheel 5 are pushed by the rotation of the driving gear 34 and the driven gear 5, and are discharged outward from the discharge port. When the moving gear 5 of the cymbal is rotated, the driven gear 5 can slide on the shaft 42, and the yaw is rotated by the positioning key 42. When the stopper portion 421 of the shaft 42 comes into contact with the stopper groove η of the driven gear 5, the liquid driven gear 5 can be prevented from being pushed toward the inner side wall 311 of the transfer chamber 31 to wear each other. 5 and 6, which is a second embodiment of the inner-rotating bearing type gear pump of the present invention, wherein the cover body 4 is provided with a ring seal 7 at the rear end of the flow guiding seat 41.
