Inner gearing gear type wheel rack power transmitting mechanism

The utility model relates to an inner gearing gear type wheel rack power transmitting mechanism, fundamentally have solved defects such as current half tooth axle drive mechanism life weak point, poor stability, and it includes half tooth frame, set up top piston, half tooth axle on half tooth frame, set up at half epaxial gear in half tooth, are equipped with the rack on the inner wall of the half tooth frame left and right sides respectively, and half tooth position of axle is in half tooth frame, and on the left of half gear and half tooth frame are interior or the rack toothing on right side, its technical essential is: it is spacing in the guide way of guide rail that half tooth frame passes through left and right sides outer wall, the top piston passes through the piston pin and installs on half tooth frame, half tooth frame bottom and the coaxial bottom piston that sets up of top piston, the spacing attenuator cylinder body under lieing in half tooth frame of bottom piston, and the bottom piston cooperatees with the inner wall of attenuator cylinder body, spacing in the attenuator cylinder body have the damping spring of submergence in lubricating oil, be equipped with a plurality of oilholes of leading on the attenuator cylinder body, lead the oilhole respectively with the guide way, half tooth frame inside casing is linked together.
