Abstract
The utility model discloses a high-speed rotary oil seal of a non-woven fabric dustproof lip. The high-speed rotary oil seal comprises a metallic framework. The interior of the metallic framework is provided with a shaft hole. The mouth portion edge of the shaft hole is provided with a rubber ring molded in a vulcanized mode. A tightening hoop spring is arranged on the outer wall of an upper end mouth portion of the rubber ring. The non-woven fabric dustproof lip is bonded on an edge of a lower end mouth portion of the rubber ring. A rubber layer molded in a vulcanized mode is arranged on the outside of the metallic framework. The high-speed rotary oil seal of the non-woven fabric dustproof lip can avoid leakage of a main lip caused by negative pressure generated between lip portions.
Description
Technical field
The utility model belongs to running shaft and uses the oil seal technique field, relates to a kind of axle technical field of sealing technology that High Rotation Speed possesses again certain dust-proof effect that adapts to.
Background technique
At present, in the application of High Rotation Speed oil sealing, in order to adapt to certain dust environment, design and axle have the rubber dust-proof lip of certain magnitude of interference usually, although this structure has certain dust excluder lips ability, cause easily during High Rotation Speed between lip to produce negative pressure and cause main lip to leak.
The model utility content
The utility model provides a kind of High Rotation Speed oil sealing of avoiding producing negative pressure between lip and causing the nonwovens dust excluder lips of main lip leakage.
The utility model technical solution problem provides following scheme:
A kind of High Rotation Speed oil sealing of nonwovens dust excluder lips, comprise metal frame, it is characterized in that: the inside of described metal frame is provided with axis hole, the oral area edge sulfidization molding of described axis hole has rubber ring, the upper end oral area outer wall of described rubber ring is provided with the lock ring spring, and the oral area edge, lower end of described rubber ring is bonded with the nonwovens dust excluder lips.
The outside sulfuration of described metal frame has rubber layer.
The utility model oil sealing is applicable to: the high-speed rotating shaft oil sealing, such as oil seal for crankshaft of engine, adopt the nonwoven cloth material instead of rubber, in the situation of the dirt exclusion capabilities that guarantees the nonwovens dust excluder lips (between dust excluder lips and the axle with magnitude of interference), because of the ventilating performance that nonwoven cloth material has, can avoid between lip producing negative pressure and cause main lip to leak.
Description of drawings
Fig. 1 is structural representation of the present utility model.
