A pin-rack gear mechanism, which consists of a rack-bar and a sprocket pinion, transforms a rotation motion into a liner one. The rack-bar has a series of pin train, and meshes with the sprocket pinion. We measured the root stress of the sprocket pinion, the driving torque, and the horizontal force of the rack bar using a pin-rack gear mechanism testing machine. Additionally, we calculated the root stress of sprocket pinion, the contact stress on the tooth surface, and the PV value. We considered the strength of the pin-rack gear mechanism comparing the measured data with the calculated results.
