Chinese patent ZL200620132712.X discloses one " dicyclo divided bearing protector "; insertion type joint is have employed in the incision of outer shroud; this insertion type joint is by being positioned at the insertion part of outer shroud one end and being positioned at forming with the groove type holding part of insertion part mating shapes of the outer shroud the other end, and the transverse dimension of the front-end and back-end of insertion part is less than intermediate portion.By adopting this insertion type joint, the structural integrity of whole bearing protector can be improved, guaranteeing that bearing protector works more reliably.But, the insertion part of this insertion type joint, when entering and exit holding part, want first to strut holding part to both sides, so after plug repeatedly, the elasticity of holding part can be caused can not to recover original shape, make can not be formed between insertion part and holding part to closely cooperate, thus there is gap in oil sealing incision, cause sealing to decline.
Summary of the invention
The object of this invention is to provide a kind of new interface form of oil sealing, jointing can be avoided to occur loosening, ensure the sealing of Sealing.
For achieving the above object, the present invention is by the following technical solutions:
A kind of oil sealing anchor shape interface, jointing is formed by embedded part with the groove of embedded part mating shapes; Described embedded part is anchor shape, and the angle between grasp and anchor pole is less than 90 degree.
Embedded part can be all-in-one-piece, and namely embedded part and oil seal ring are one; Or embedded part is split type, is independently one piece separately, and on oil seal ring, is provided with corresponding groove.Its material of independent embedded part can be identical with oil seal ring, also can be different from oil seal ring, adopts rubber, plastics or metal etc.The periphery of embedded part can also be provided with metal hemming edge.
The top of anchor shape embedded part is wedge angle, and the hook end of described grasp is acute angle, and grasp root can be cambered surface, plane or the flank of tooth.Interface any direction is all the through curve of non-rectilinear or broken line, it is the three-dimensional barb design of 3D, and it is embedded into the trench design partly containing grasp designing shape therewith and match, two-part have opposition to stop when being separated in any direction or exiting, positive lock, prevent from departing from, and play effective seal action.
Further technological scheme, the barb of sealed interface is inlayed and is adopted self-locking design, namely the hook end angle of embedded part is slightly larger than the hook end angle being embedded into groove matched, coupling mechanism force can be produced voluntarily under the elastic reaction of material after making it inlay, make anchor shape embedded part forward be embedded into groove and be adjacent to, realize the self-sealing of cutting end face.
Its grasp is inlayed the subdivision otch that connection not only can be used for single oil seal ring and is connected, and the mutual entirety that also can be applied between two rings of a Combined grease seal ring or many rings inlays connection.On the axial direction that embedded part and groove can be arranged on oil seal ring or in the radial direction, or both direction all uses this interface shape.If when it is applied to the mutual integrated connection between two rings of a Combined grease seal ring or multiple ring, its embedded part can be formed as a domain or be divided into several sections, it is embedded into part can be an annular trench or be divided into several sections of grooves.
The shape (being generally circle, ellipse or rhombus) of middle Embedded Division compared to existing technology, oil sealing interface of the present invention adopts the embedded part of anchor shape wedge angle, embedded part forever can not be moved back out along ring circumference after embedding groove, serve the effect of reliable anchoring, permanent locking, what avoid that Reusability brings loosens, enhance the sealing of jointing, and reduce seal arrangement to the flexible requirement of material, can apply widely.
