Abstract
The utility model discloses a novel conical roller thrust bearing with hermetically sealed construction which substantially comprises rollers (7), a bearing inner ring (6), a bearing outer ring (2), and a set of seals (1), wherein the rollers are arranged between the bearing inner ring and the bearing outer ring. The set of seals (1) comprises a packing ring, an O-shaped obturating ring (4, 5), and a lip packing (3) and forms self-sealing conformation to prevent external mishmash from entering the inner portion of the bearing, thereby prolonging useful time of the bearing.
Description
Technical field:
The utility model relates to roller bearing design and fabrication technology field, a kind of tapered roller thrust bearing of novel band sealing configuration.
Background technique:
The use condition that depends on material, heat treatment, bearing manufacturing technology level and the bearing of making bearing the working life of rolling bearing.Under bearing material, heat treatment, bearing manufacturing technology level and lubricated identical situation, the life-span length of the clean degree decision bearing of bearing Environmental Conditions.Often cause bearing to lose efficacy in advance in a lot of applications, can not get guaranteeing that therefore stoping foreign material to enter bearing inside is to prolong the bearing key factor of actual life the actual life of bearing because foreign material enter bearing inside.
At present, tapered roller thrust bearing commonly used is made up of bearing blowout patche, seat ring and roller, itself is not with sealing configuration its bearing, do not have sealing function, can't stop foreign material to enter bearing inside, the cleaning ambient that requires during bearing operation is not being met, often cause that bearing lost efficacy in advance, do not reach desired life the actual life of bearing, this structure needs auxiliary sealing device, thereby has limited the application of this kind bearing under some particular surroundings.
Summary of the invention:
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of tapered roller thrust bearing of novel band sealing configuration, and it adopts the sealing configuration of bearing self, has stoped external impurities to enter bearing inside effectively, has prolonged bearing life.
For achieving the above object, the utility model adopts following technological scheme:
The tapered roller thrust bearing of described novel band sealing configuration, it mainly contains roller, bearing blowout patche, bearing race and black box and constitutes, roller is installed between bearing blowout patche and the bearing race, and black box comprises seal ring, O RunddichtringO and lip packing, and it constitutes self sealing structure.
The tapered roller thrust bearing of described novel band sealing configuration, processing one groove on the internal diameter of its bearing blowout patche, and an O RunddichtringO is installed, external diameter is installed a seal ring by being tightly fixed.
The tapered roller thrust bearing of described novel band sealing configuration, processing one groove on the internal diameter of its bearing race, and an O RunddichtringO is installed, be processed with a step trough on the external diameter, by bonding fixed installation one lip packing, lip packing constitutes sealing with the seal ring that is installed on the bearing blowout patche in the step trough.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
The tapered roller thrust bearing of band sealing configuration of the present utility model adopts rational selfsealings assembly, when not increasing bearing self size, effectively block foreign material and entered bearing inside, guaranteed the cleaning operation of bearing, prolonged bearing life, simultaneously, enlarged the using scope of this bearing.
Description of drawings:
Fig. 1 is the tapered roller thrust bearing structural representation of novel band sealing configuration;
Number in the figure: 1-seal ring; The 2-bearing race; The 3-lip packing; 4,5-O RunddichtringO; 6-bearing blowout patche; The 7-roller.
Embodiment one:
As shown in Figure 1, the tapered roller thrust bearing of the band sealing configuration that this is novel, it mainly contains roller (7), bearing blowout patche (6), bearing race (2) and black box and constitutes, roller (7) is installed between bearing blowout patche (6) and the bearing race (2), black box comprises seal ring (1), O RunddichtringO (4,5) and lip packing (3), and it constitutes self sealing structure.Processing one groove on the internal diameter of its bearing blowout patche (6), and an O RunddichtringO (5) is installed, external diameter is installed a seal ring (1) by being tightly fixed; Processing one groove on the internal diameter of its bearing race (2), and an O RunddichtringO (4) is installed, be processed with a step trough on the external diameter, fixedly mount a lip packing (3) by bonding in the step trough, lip packing (3) constitutes sealing with the seal ring (1) that is installed on the bearing blowout patche (6), thereby the blocking-up foreign material enter bearing inside between bearing blowout patche and the bearing race.
Claims (3)
1, a kind of tapered roller thrust bearing of novel band sealing configuration, it is characterized in that: it is made of roller (7), bearing blowout patche (6), bearing race (2) and black box, roller is installed between bearing blowout patche and the bearing race, black box comprises seal ring (1), O RunddichtringO (4,5) and lip packing (3), it constitutes self sealing structure.
2, the tapered roller thrust bearing of novel band sealing configuration according to claim 1 is characterized in that: processing one groove on the internal diameter of its bearing blowout patche (6), and an O RunddichtringO (5) is installed, external diameter is installed a seal ring (1) by being tightly fixed.
