Abstract

The utility model discloses an agricultural machinery bearing is sealed to contact, including inner circle, outer lane, steel ball and sealing washer, the sealing washer including steel skeleton and seal lip, the radial outer end of steel skeleton clamps to be fixed in on the outer lane, extend to the inner circle orientation radial the inner of steel skeleton, just the radial inner terminal surface and the inner circle of steel skeleton keep certain clearance outward between the periphery, the seal lip be fixed in the radial inner inboard of steel skeleton, just the seal lip for connect the m shape structure that constitutes by outer lip, well interlabium and epipharynx, outer lip and steel skeleton radial inner paste join in marriage fixed, well interlabium and epipharynx all extend to with the outer periphery sealing contact of inner circle, and be in it forms a depot fat space to enclose to connect between the inner wall of epipharynx, steel ball, the outer periphery of inner circle and outer lane. Through adopting the structure mentioned above, the utility model provides a better, the longer agricultural machinery bearing is sealed to contact of life of sealed effect.

Description

A kind of contact seal agricultural machinery bearing
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of contact seal agricultural machinery bearing.
Background technique
Agricultural machinery bearing is the class bearing be applied on farm machinery, but the seal ring on existing agricultural machinery bearing mostly is single lip sealing ring, and due to agricultural machinery bearing applied environment severe, in use, some easily impact bearing sealed ring as the dust such as stalk, straw impurity, and the seal ring of existing single lip is often difficult to stop entering of these dust impurity etc., thus easily cause the deterioration failure of Bearing inner lubricating grease or affect the normal operation of bearing, and then greatly shortened in the working life of bearing.
Summary of the invention
For the deficiencies in the prior art, the utility model provides that a kind of sealing effect is better, the contact seal agricultural machinery bearing of longer service life.
For achieving the above object, the utility model provides a kind of contact seal agricultural machinery bearing, include inner ring, outer ring, steel ball and seal ring, described steel ball and seal ring are arranged between inner ring and outer ring, and described seal ring correspondence is positioned at the axially outside of steel ball, described seal ring includes Steel Skeleton and sealing lip, the radial outer end of described Steel Skeleton clamps and is fixed on outer ring, the radial inner end of described Steel Skeleton extends to inner ring direction, and keep certain interval between the radial inner end end face of described Steel Skeleton and inner ring outer peripheral surface, described sealing lip is fixed on the inner side of Steel Skeleton radial inner end, and described sealing lip is by outer lip, the m shape structure that middle interlabium and epipharynx connect and compose, described outer lip and the radial inner end of Steel Skeleton paste join fixing, described middle interlabium and epipharynx all extend to seal with the outer peripheral surface of inner ring and contact, and at described epipharynx, steel ball, enclose between inner ring outer peripheral surface and the inwall of outer ring and connect formation depot fat space.
The beneficial effects of the utility model are: adopt said structure, because the arranged outside of described sealing lip has Steel Skeleton, therefore have good protecting against shock function; And described sealing lip is the m shape structure connected and composed by outer lip, middle interlabium and epipharynx, then can be formed multi-layer sealed, can prevent extraneous dust impurity etc. from entering into Bearing inner well, effectively completely cut off the contact between Bearing inner and outside, thus substantially prolongs the working life of bearing, meanwhile, due at described epipharynx, steel ball, enclose between inner ring outer peripheral surface and the inwall of outer ring and connect formation depot fat space, therefore such vibrational power flow also helps storing lubricating grease.In addition, keep certain interval between the radial inner end end face of described Steel Skeleton and inner ring outer peripheral surface, not only can effectively avoid Steel Skeleton in use to scratch inner ring, and can also effectively reduce friction bearing capacity, what bearing was run be more smooth and easy.
The inwall that the utility model can be set to described outer ring further offers dustproof groove, and the radial outer end interference of described Steel Skeleton is installed in described dustproof groove.By above-mentioned setting, be not only convenient to being mounted with of seal ring, and be connected firmly after assembling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Give a kind of contact seal agricultural machinery bearing as shown in Figure 1, include inner ring 1, outer ring 2, steel ball 3 and seal ring 4, described steel ball 3 and seal ring 4 are arranged between inner ring 1 and outer ring 2, and described seal ring 4 correspondence is positioned at the axially outside of steel ball 3, described seal ring 4 includes Steel Skeleton 41 and sealing lip 42, the inwall of described outer ring 2 offers dustproof groove 21, and radial outer end 411 interference of described Steel Skeleton 41 is installed in described dustproof groove 21.The radial inner end 412 of described Steel Skeleton 41 extends to inner ring 1 direction, and keep certain interval 5 between radial inner end 412 end face of described Steel Skeleton 41 and inner ring 1 outer peripheral surface, described sealing lip 42 is fixed on the inner side of Steel Skeleton radial inner end 412, and described sealing lip 42 is by outer lip 421, the m shape structure that middle interlabium 422 and epipharynx 423 connect and compose, described outer lip 421 and the radial inner end 412 of Steel Skeleton 41 paste join fixing, described middle interlabium 422 and epipharynx 423 all extend to seal with the outer peripheral surface of inner ring 1 and contact, and at described epipharynx 423, steel ball 3, enclose between the inwall of inner ring 1 outer peripheral surface and outer ring 2 and connect formation depot fat space 6.By adopting said structure, the utility model provides that a kind of sealing effect is better, the contact seal agricultural machinery bearing of longer service life.
