[0002] The current drive system of a tracked armored vehicle uses a gear transmission form. One end of the main drive gear is connected to the gearbox, and the other end is connected to the side reducer. The side reducer is then connected to the driving wheel to drive the track. After the main drive gear is connected to the side reducer, it is necessary to measure the meshing clearance of the main drive gear and the side reducer gear of 0.1mm-0.7mm. However, since the gear meshing position is inside the box after assembly, the gear transmission group is inside the box as a whole, and the gear group cannot be seen from the outside, it is impossible to measure the gear transmission meshing clearance by measuring the meshing lead sheet thickness with a vernier caliper, which brings new difficulties to actual production and affects production efficiency.
