Its function is to control the valve shaft of the valve intake volume. The machining accuracy of the throttle shaft surface is relatively high, especially the machining of the long groove on the electronic throttle shaft. The existing throttle shaft diameters are 8mm and 10mm, and the lengths are 84.3mm to 137.2 mm in more than 30 specifications. There are 60° center holes at both ends, screw holes, screw threads, annular grooves, etc. on the shaft. There is a long flat groove in the middle of each shaft, which is symmetrically opened on both sides of the central axis. The groove width is 1.15mm to 2.08mm, and the length varies from 38.3 to 62.5. The two ends of the groove are crescent-shaped.
