PROBLEM TO BE SOLVED: To provide a gear pump arranged so that the discharge amount does not increase even when the revolving speed of a drive gear has increased to result in exceeding the prescribed region, without causing the structure to be complicated and without requiring a large space for installation.SOLUTION: The drive gear 1 is composed of a rising shaped inner race 7 and an outer race 9 furnished with tooth profile at the outer periphery, in which torque limiters 6, 6, ... are installed between the inner 7 and outer races 9 so that the races 7 and 9 make slippage relative to each other when a torque exceeding the prescribed region is generated. |
