AI Technical Summary
Traditional gearbox gear mounting devices can easily cause the spindle to rotate when installing helical or spiral gears, leading to misalignment of the tooth contact area, resulting in noise or abnormal wear. In addition, tools are easily scattered and need to be repeatedly searched, affecting installation efficiency and smoothness.
A gearbox gear mounting device was designed. By setting circular grooves and insertion holes on the platform, the main shaft is fixed by a fixing device to ensure that the gears are inserted and fixed in order of size. Combined with a storage slot and a reset device, tools are stored in a centralized manner to prevent the main shaft from rotating and the tools from falling out.
It effectively prevents the spindle from rotating during press-fitting by helical or spiral gears, improving installation efficiency. The centralized storage of tools reduces operational complexity and the risk of contamination.
