Touching, dustproof and waterproof weak effect, quick abrasion, service life is short.The sealing ring of non-contacting seal and the cooperation face of bearing parts are
Matched in clearance, can only prevent the particle foreign material that some are big from entering in bearing, it is impossible to prevent soiling solution and little dust particles from entering,
Sealing effectiveness is very poor.Bearing inner grease is also easy to be thrown out of, and causes bearing to lack and lubricates and burnout phenomenon.Existing bearing
Sealing structure, sealing effectiveness is poor, works under the conditions of not being suitable for having the bad working environments such as soiling solution, mud, cargo sweat are strong.
Utility model content
The purpose of this utility model is, the problem existed for existing contact seal roller bearing, it is provided that a kind of " Z "
Type end side contact seal roller bearing.The sealing ring of this structure and the cooperation face of bearing are end contact, so sealing effectiveness
Very well.Make bearing when working under the conditions of the bad working environments such as soiling solution, mud, grit, cargo sweat are strong, bearing can be protected not
Being corroded by outside foreign material, protection Bearing inner grease is not thrown out of and causes premature bearing failure, extends bearing service life.
The purpose of this utility model and solve it and technical problem is that and realize by the following technical solutions.
According to one " Z " the type end side contact seal roller bearing that the utility model proposes, it includes outer ring 1, outer ring
Internal diameter 11, interior axle 2, interior axle external diameter 21, interior axle bumper limit end face 22, cylinder rolling element 3, loose rib 5, loose rib end face 51, wherein,
Also include " Z " type end side contact sealing ring 4, in " Z " type end side contact sealing ring 4 includes sealing ring external diameter 41, sealing ring
Footpath 42, sealing ring end face 43；Described " Z " type end side contact sealing ring 4 is arranged between outer ring 1 and interior axle 2, and with outer ring 1
Being tightly connected with interior axle 2, described " Z " type end side contact sealing ring 4 contacts with outer ring 1 and loose rib 5.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Aforesaid one " Z " type end side contact seal roller bearing, wherein, described sealing ring external diameter 41 is arranged at outer ring
In the groove of internal diameter 11, interior axle external diameter 21 is arranged in internal diameter of the seal ring 42.
Aforesaid one " Z " type end side contact seal roller bearing, wherein, described sealing ring end face 43 and interior axle bumper limit
End face 22 contacts；Described sealing ring end face 43 contacts with loose rib end face 51.
Aforesaid one " Z " type end side contact seal roller bearing, wherein, shape between outer ring 1, interior axle 2 and loose rib 5
Become confined space.Can effectively prevent soiling solution, the foreign material such as mud, grit enter Bearing inner, can prevent the lubrication of Bearing inner
The bad working environments conditions such as fat is run out of outside bearing, makes bearing be operable with silt many, and cargo sweat is strong.
By technique scheme, a kind of " Z " type end side contact seal roller bearing of the utility model can reach quite
Technological progress and practicality, and there is the extensive value in industry, compared with prior art there is clear advantage
And beneficial effect, it at least has the advantage that
" Z " of the present utility model type end side contact sealing ring is that face contacts with the cooperation of bearing parts, has sealing effectiveness
Very well, the advantage such as length in service life.Can effectively prevent soiling solution, the foreign material such as mud, grit enter Bearing inner, can prevent simultaneously
The lubricating grease of Bearing inner is run out of outside bearing, and this bearing can be widely applied to load weight, and silt is many, and cargo sweat waits by force severe
Working condition.
In sum, a kind of " Z " type end side contact seal roller bearing of the utility model has significantly to enter technically
Step, and there is obvious good effect, it is really a new and innovative, progressive, practical new design.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can be practiced according to the content of specification, and in order to allow above and other purpose of the present utility model, feature
Can become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.
