The utility model is set to further: the axial madial wall of described interior sealing lip be from outside diameter to internal side diameter in the scarf tilted towards Bearing outer.
By adopting technique scheme, interior sealing lip contacts with inner ring and seals reliably, good seal performance.
The utility model is set to further: the inner peripheral surface of described outer ring is provided with dustproof groove, and described rubber seal also comprises the dust excluder lips being located at outside diameter, and described dust excluder lips is interference fitted in dustproof groove.
By adopting technique scheme, seal ring and outer ring are installed and are coordinated reliably, and sealing is reliable.
The utility model is set to further: the internal side diameter of described rigid backbone is extended with elbow towards Bearing inner upset, and described dust excluder lips is corresponding with the position of elbow.
By adopting technique scheme, improving the intensity of dust excluder lips, making dust excluder lips solid and reliable, improve sealability.
The utility model is set to further: the axial outboard end mouthpiece of described dustproof groove has the chimb extended internally, and the outside of described dust excluder lips has the inclined-plane of joining with chimb card.
By adopting technique scheme, dust excluder lips coordinates solid and reliable with dustproof groove, improves sealability.
The utility model is set to further: the madial wall of described dustproof groove is to the plane of inclination that axial inner tilts from bottom, and the axis inner side of described dust excluder lips is the slope with the plane of inclination adaptation of dustproof groove.
By adopting technique scheme, the plane of inclination of dustproof groove coordinates with chimb, dust excluder lips is better fixed in dustproof groove, and improves sealability.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model specific embodiment structural representation;
Fig. 2 is part A partial enlarged view in Fig. 1.
Embodiment
See accompanying drawing 1 and accompanying drawing 2, a kind of single facer type tapered roller bearing disclosed in the utility model, include outer ring 1, inner ring 2, tapered roller 3 and retainer 4, described tapered roller 3 is arranged between outer ring 1 and inner ring 2 through retainer 4, described outer ring 1 greatly end is provided with seal ring 5, the inner peripheral surface of outer ring 1 is provided with dustproof groove 11, seal ring 5 includes rigid backbone 51, and the rubbery sealed body 52 be attached in rigid backbone 51, rubbery sealed body 52 comprises the sealing lip being located at internal side diameter, described sealing lip contacts with the inner peripheral surface of inner ring 2 and is sealed and matched, described sealing lip includes interior sealing lip 521 and outer seal lip 522, described interior sealing lip 521 and outer seal lip 522 all radially extend, and described outer seal lip 522 tilts to extend towards Bearing outer, described rubbery sealed body also comprises the dust excluder lips 523 being located at outside diameter, dust excluder lips 523 be interference fitted in dustproof groove 11 reach seal ring sealing be arranged on outer ring.In the outer ring of tapered roller bearing, large end place establishes seal ring, and namely design seal ring at the large end (the larger one end of diameter) of bearing, thus avoid impurity to enter Bearing inner, make tapered roller bearing better meet the needs of the situation of single facer, structure is simple; And interior sealing lip and outer seal lip ensure that sealing is reliable, outer seal lip adopts inclined design, and sealed elastic is better, and effectively can stop that impurity enters from the cooperation place of outer seal lip, has the advantage of good airproof performance.The axial madial wall 5211 of described interior sealing lip 521 be from outside diameter to internal side diameter in the scarf tilted towards Bearing outer.Interior sealing lip contacts with inner ring and seals reliably, good seal performance.
