1. The daily maintenance of machinery and equipment is very important. Regardless of whether new or old machinery and equipment are used, the principle of "maintenance first, maintenance as a supplement" should be implemented.
2. The belt drive can be divided into V-belt drive, flat belt drive and circular belt drive. The vacuum pump used in our PSA is V-belt drive.
3. In the belt transmission mechanism, there is generally a tensioning device for adjusting the tensioning force.
4. When installing the pulley, the center lines of the two pulleys must be parallel, and it should be ensured that the pulley does not skew and jump on the axis.
5. The failure mode of belt drive is mainly manifested in slippage and fatigue damage.
6. The role of the backlash of the gear pair: First, to prevent the gear teeth from being stuck due to errors and thermal deformation of the gear pair. The second is to leave space for the lubricating surface between the tooth surfaces.
