Description

Technical Field

[0001] The present invention relates to a gasket selection device for gearbox docking. Background Art

[0002] When the front box and the rear box are docked in the assembly field of agricultural machinery gearboxes, the gap control in the middle is achieved by adjusting gaskets. The measurement and selection of adjusting gaskets have always been a difficult problem. The front box and the rear box of the gearbox are assembled in two separate assembly areas, and there is no way to pre-assemble or pre-detect in advance. Once the docking gap between the front box and the rear box is inappropriate, gear collisions or overheating and seizure of bearings will occur;

[0003] To detect the state of the front and rear of the gearbox, as Figure 6 shown, there will be an adjusting washer between the sliding sleeves of the front box and the rear box. By measurement and selection, the required thickness of the adjusting washer can be selected, and then the appropriate washer thickness can be measured and selected from multiple specifications of adjusting washers;

[0004] Currently, the equipment used in the same industry is to measure manually with a measuring tool (depth gauge), and the final thickness of the adjusting gasket is measured and selected through manual calculation; the qualified rate of manual measurement and selection is relatively low, about 55%, the operation is relatively cumbersome, the measurement error is large, and the rework workload is large; Summary of the Invention
