To adjust the meshing clearance between the gears and racks, it is first necessary to ensure that the surfaces of the gears and racks are clean, free of oil and impurities. The specific steps are as follows:

Choose the appropriate adjustment tool. Such as micrometers, feeler gauges, vernier calipers, etc., to improve adjustment accuracy. one

Loosen the fixing screws of the gearbox so that it can move left and right.

Measure the gap between the gear and rack using the selected tool and record the value.

Based on the measurement results, gradually adjust the position of the gearbox and reduce the clearance.

Measure the gap again after adjustment, and if necessary, repeat the adjustment until it meets the requirements.

After adjustment, tighten the fixing screws of the gearbox.

    In addition, it is necessary to check the meshing and rotation of the gears to ensure their normal operation. Copper foil can also be used as an auxiliary material to adjust the clearance, for example, by placing a preset thickness of copper foil and then adjusting the gear until the clearance meets the requirements. The meshing clearance between gears and racks can also be adjusted through waist shaped holes and bolts, precision washers, eccentric wheels, and other methods. Among these methods, the waist shaped hole and bolt adjustment structure are simple and convenient to adjust, precision gasket adjustment provides high adjustment accuracy, and eccentric wheel adjustment is suitable for heavy-duty situations. Each method has its applicable scenarios and advantages and disadvantages, and the appropriate adjustment method should be selected according to the actual situation
