Equipped with spring ring, the upper surface of the end cap is equipped with the sealed groove matched with the seal convexity of the labyrinth disc lower end, position
It is connected with bearing on the outside of the axis below the oil baffle disc, the bearing is located in the axis hole of the cabinet.
Particularly, the quantity of the seal convexity of the labyrinth disc lower end is no less than two.
Particularly, the quantity of the oil trap is no less than three.
Particularly, the quantity of the oil baffle disc is one or two.
The beneficial effects of the utility model are: the utility model felt circle, labyrinth disc and oil baffle disc triplicity, common group
At sealing structure, play the role of sealing and dustproof oil-leakage-prevention, sealing effect is good, reduces the friction generated when axis rotation, avoids
Damage of components improves the security reliability of axis, extends and uses the time；Oil baffle disc has the function of that gear oil, oil-recovery tank are set
A small amount of oil spill can be flowed back by setting, and avoid the occurrence of leakage phenomenon.
