| description | The utility model discloses a gear pump capable of reducing abrasion of a gear shaft. Driven gear shafts on the two sides of a driven gear, a second shaft hole and a first shaft hole form a revolute pair, a first driving gear shaft and a second driving gear shaft on the two sides of a driving gear, a through hole and the other first shaft hole form revolute pairs respectively, and spiral grooves are formed in the second driving gear shaft and the two driven gear shafts. Mechanical guide-out devices are arranged in the second mounting hole and the two first mounting holes, and channels are formed in the second mounting hole and the two first mounting holes. Hard particles on the cylindrical surface of the driven gear shaft or the second driving gear shaft are conveyed to the shaft end through the spiral groove, abrasion to the cylindrical surface of the driven gear shaft or the second driving gear shaft is reduced, the piston rod is pushed through the hard particles gathered at the shaft end, the channel is co |
