Effects of Fillet on Kinematic Characteristic of Internal Gear Couple

Internal gear couple is the key component of high-pressure internal gear pumps, kinematic characteristic of which directly influences performance of the pump. Fillet is always ignored in the studies of gear transmission. This paper presents kinematic analysis of internal gear couple by using Adams which takes fillet into account. On the base of simulation results, the effects of fillet on kinematic characteristic of internal gear couple are concluded.
