AI Technical Summary
The sealing devices of existing ball mill large gears are prone to reduced sealing performance due to wear and vibration during use, leading to lubricating oil leakage and affecting the workshop environment and product quality.
The system employs a combination of dynamic and static labyrinth seals. The first sealing groove is formed by the first and second sealing teeth, and the second sealing groove is formed by the third and fourth sealing teeth, thereby achieving a non-contact labyrinth seal and preventing lubricating oil leakage.
It effectively improves sealing performance, prevents lubricating oil leakage, extends the service life of the sealing device, and has a simple structure and low cost.
