VALVE CLEARANCE MACHINE

Abstract

The invention relates to a valve lapping machine comprising a first part with two gears (6), (7) in which one gear (7) is responsible for driving to the intermediate gear set (7'; 8) of the second part to change the transmission ratio and convert the rotational motion into a circular arc motion of about 1 / 4 to 1 / 6 of a circle and transmit to the swirling shaft (3) of the third part which is arranged concentrically with the shaft (2) of the second part to latch (swirl) the valve; and a gear (6) of the first part drives to the gear (6') which is fixed to the shaft (2) of the second part causing the motion converter (8', 2.1', 2.1, 2.2") to gradually rotate in a circle around the shafts (2) and (3) and simultaneously with the shaft (3) moving in a circular arc.
