Abstract
The invention discloses a sealing cover for a bearing. The sealing cover comprises a tightening boss and a sealing bulge which is fixedly connected with the tightening boss, wherein a plurality of connecting holes for allowing bolts to penetrate through are uniformly distributed in the tightening boss; the sealing bulge is of a conical structure; a large end of the sealing bulge is connected with the tightening boss; a positioning groove is formed in the circumferential side of the sealing bulge and is close to a small end of the sealing bulge; a sealing rubber ring is arranged at the small end of the sealing bulge in a sleeving way; the inner wall of the sealing rubber ring is attached to the sealing bulge; the outer wall of the sealing rubber ring is obliquely arranged toward the sealing bulge. The sealing cover disclosed by the invention is convenient to mount and dismount and is easy for processing.
Description
Technical field
The present invention relates to bearing technology, be specifically related to a kind of bearing seal cover.
Background technique
Bearing seal cover of the prior art, the end face of sealed rubber ring one end face and bearing seal cover is fitted, other end and the body surface of sealed rubber ring offset, and are fixedly connected with by bearing seal cover by bolt with body, make bearing seal cover be tightly pressed on body by sealed rubber ring simultaneously.Contact with face because this structure belongs to face, oil-proof to ensure it to fit tightly, then need the thin and thick of sealed rubber ring evenly, the axis of bearing seal cover is vertical with end face, processing difficulties; Also need larger power to be compressed by sealed rubber ring, bother when installation, dismounting bearing seal cover.
Summary of the invention
For the defect that above-mentioned prior art exists, technical problem to be solved by this invention be to provide a kind of installation, convenient disassembly and be easy to process bearing seal cover.
In order to solve the problems of the technologies described above, the invention provides a kind of bearing seal cover, the sealing projection comprising fastening protrusion and be fixedly connected with it, fastening protrusion is evenly equipped with the attachment hole that several can make bolt pass.Sealing projection is cone structure, and the large end of sealing projection is connected with fastening protrusion; All sides of sealing projection offer locating slot, and locating slot is near the small end of sealing projection.The small end of sealing projection is arranged with O-ring seal, and the inwall of O-ring seal fits with sealing projection, and the outer wall of O-ring seal is obliquely installed to sealing is raised.
Adopt the bearing seal cover of said structure, because sealing projection is cone structure, its cross-sectional diameter is all not identical, can adapt to different size by sealed port, thus make sealing projection and closely cooperated by sealed port; Because the outer wall of O-ring seal is obliquely installed to sealing is raised, easier when installing bearing seal cover; Because all sides sealing projection offer locating slot, when dismantling bearing seal cover, prevent O-ring seal from coming off.
Improve as to a step of bearing seal cover preferred version, the side of described sealing projection is 40 ° ~ 60 ° with the central shaft angle angle of sealing projection.
After adopting such structure, when dismantling bearing seal cover, make O-ring seal difficult drop-off; Make sealing projection adapt to less of sealed port simultaneously.
Further improvement as the above-mentioned bearing seal cover of the present invention: described fastening protrusion is structure as a whole with sealing projection.
After adopting such structure, add man-hour, be easy to ensure that fastening protrusion is coaxial with sealing projection, during installation, be convenient to location; And be easy to the processing of bearing seal cover.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of bearing seal cover of the present invention.
In figure, 1 is attachment hole, and 2 is sealing projection, and 3 is O-ring seal, and 4 is locating slot, and 5 is fastening protrusion.
embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is described in further detail:
As shown in Figure 1, the bearing seal cover of one embodiment of this invention, the sealing projection 2 comprising fastening protrusion 5 and be structure as a whole with it, fastening protrusion 5 is evenly equipped with six attachment holes 1 that bolt can be made to pass.Sealing projection 2 is cone structure, and the side of sealing projection 2 is 45 ° with the central shaft angle angle of sealing projection 2.The large end of sealing projection 2 is connected with fastening protrusion 5; All sides of sealing projection 2 offer locating slot 4, and locating slot 4 is near the small end of sealing projection 2.The small end of sealing projection 2 is arranged with O-ring seal 3, and the inwall of O-ring seal 3 fits with sealing projection 2, and O-ring seal 3 inwall is also provided with the projection with locating slot 4 clamping, and the outer wall of O-ring seal 3 is obliquely installed to sealing raised 2.
During use, first sealing projection 2 is snapped fit onto by sealed port place, then pass attachment hole 1 with bolt and be threaded with body, and then make sealing projection 2 place and be extruded distortion by the O-ring seal 3 between sealed port place, and then will be sealed by sealed port.
Below by reference to the accompanying drawings to described be only the preferred embodiment of the present invention; but the present invention is not limited to above-mentioned mode of execution; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; can also make various distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
