The type and function of the oil seal

Labyrinth oil seal: Labyrinth oil seal its gap with the shaft can not be too large or too small, the gap is too small to wear the shaft, too large is oil leakage, and because the seal is fixed on the housing and the shaft is relatively fixed, can not adapt to and compensate for the floating of the shaft, the shaft vibration will be the oil seal gap grinding bigger and bigger, eventually resulting in oil leakage.

Rubber skeleton oil seal: rubber skeleton oil seal by the metal skeleton with rubber wrapped, the inside of the sealing surface in order to be able to effectively float with the shaft, a special addition of a spring, although to overcome the labyrinth seal can not float with the shaft of the deficiency, but will produce wear on the shaft, itself will also wear, to a certain extent will lead to oil leakage.

Felt oil seal: Felt oil seal is processed on the bearing cover a "V" groove, with its own elastic action on the shaft for sealing, but easy to suck in tiny particles to make the felt lose elasticity, can not compensate for the vibration of the shaft, resulting in failure oil leakage.
