Abstract
The invention discloses a bearing sealing ring with double steel ring skeletons. The bearing sealing ring is characterized by comprising the steel ring skeletons on the left side and the right side and a middle rubber ring, wherein the steel ring skeleton on the left side comprises a first upper vertical beam, a first bending beam protruding inwards and a lower vertical beam; the steel ring skeleton on the right side comprises an annular locking beam at the top; the annular locking beam is provided with an opening; the first upper vertical beam is arranged at the opening in a clamping manner; the right end of the annular locking beam is connected with a second upper vertical beam; the second upper vertical beam is connected with a 90-degree second bending beam; a bent groove matched with the first bending beam is formed in the left side of the runner ring; the top surface and the right side surface of the rubber ring are matched with and propped against the inner side surface of the second bending beam.
Description
Technical field
The present invention relates to a kind of bearing sealed ring.
Background technology
Bearing sealed ring is the main seal part in bearing, is not only saved in bearing by grease, prevents again foreign debris or dust from entering in bearing simultaneously, can be effectively improved the service life of bearing.
Bearing sealed ring is generally passed through glued together by the rubber ring of the steel ring skeleton in outside and inner side.
This structure can play good sealing effectiveness in general environment, but when working in some adverse circumstances, the rubber ring of this structure and steel ring skeleton are easy to come off, and insufficient strength, it is easy to deformation failure.
Summary of the invention
The present invention is aiming at the problems referred to above, it is provided that a kind of work in adverse circumstances still can ensure the bearing sealed ring of sealing effectiveness very well.For solving these problems, the present invention by the following technical solutions:
A kind of bearing sealed ring of pair of steel ring skeleton, it is characterized in that, steel ring skeleton and middle rubber ring including the left and right sides, wherein the steel ring skeleton in left side includes vertical beam on first, the first inwardly projecting bending beam and lower vertical beam, the steel ring skeleton on right side includes the annular locking beam at top, described annular locking beam is provided with opening, on described first, vertical beam clamping is arranged on opening part, the right-hand member of described annular locking beam connects vertical beam on second, on described second, vertical beam connects the second bending beam of 90 °, the left side of described rubber ring is provided with and bends, with first, the curved groove that beam coordinates, the medial surface cooperation of the end face of described rubber ring and right flank and the second bending beam pushes against.
The technical characteristic of the present invention also resides in: the lower end of described second bending beam is connected to cant beam, and described cant beam tilts laterally.
Adopt above technical scheme, the invention have the advantages that
1. rubber ring of the present invention is arranged between two steel ring skeletons, so can increase intensity, and rubber ring is unlikely to deform, difficult drop-off, and rubber ring is additionally provided with and bends, with first, the curved groove that beam coordinates, and can further increase intensity, adapt to harsh environments.
2. on the right side of the present invention, steel ring skeleton is provided with annular locking beam, this annular locking beam is provided with opening, on first, vertical beam inserts opening part, after steel ring skeleton is installed in the seal groove of outer ring, the opening of this annular locking beam can inwardly tighten up, thus locking vertical beam on first, it is prevented that two steel ring skeletons depart from.
3. on the right side of the present invention, the lower end of steel ring skeleton is provided with cant beam, and this cant beam tilts to the right, it is possible to when better adapting to install, the deformation of sealing lip.

Fig. 1 is the sectional view (only illustrating the first half) of the present invention.
Fig. 2 is the sectional view (only illustrating the first half) of steel ring skeleton on the left of the present invention.
Fig. 3 is the sectional view (only illustrating the first half) of steel ring skeleton on the right side of the present invention.
Fig. 4 is the sectional view (only illustrating the first half) of rubber ring of the present invention.
Number in the figure: steel ring skeleton on the left of in the of 1, vertical beam on 11 first, 12 first bending beams, 13 times vertical beams, steel ring skeleton on the right side of 2,21 annular locking beams, 211 openings, vertical beam, 23 second bending beam, 24 cant beams, 3 rubber rings, 31 curved grooves on 22 second.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further detailed explanation:
Embodiment 1: as shown in Figure 1, Figure 2, Figure 3 and Figure 4, the bearing sealed ring of a kind of pair of steel ring skeleton, including the rubber ring 3 of left side steel ring skeleton 1, right side steel ring skeleton 2 and centre.
The steel ring skeleton in left side includes vertical beam 11 on first, the inwardly projecting first bending beam 12 and lower vertical beam 13.
The steel ring skeleton on right side includes the annular locking beam 21 at top, described annular locking beam is provided with opening 211, on described first, vertical beam 11 inserts opening 211 place, and on the width ratio first of described opening 211, little about the 0.2mm of thickness of vertical beam 11, so can facilitate vertical beam 11 in opening clamping first.The right-hand member of described annular locking beam connects vertical beam 22 on second, and on described second, vertical beam 22 connects the second bending beam 23 of 90 °, and the lower end being told the second bending beam 23 is connected to cant beam 24, and described cant beam 24 tilts laterally.
The left side of rubber ring is provided with the medial surface cooperation bending the curved groove 31 that beam 12 coordinates, the end face of described rubber ring and right flank and the second bending beam 23 with first and pushes against.
Can be glued between the steel ring skeleton of rubber ring of the present invention and both sides, it is also possible to do not bond, not affect sealing effectiveness.
The present invention is in use, need to arrange the circular arc seal groove supporting with annular locking beam in the outer ring of bearing, the arc diameter of this seal groove general is more smaller than the external diameter of annular locking beam 21, so after bearing sealed ring is snapped in seal groove, annular can be locked the inside clamping of beam 21 by seal groove, so that the opening 211 of annular locking beam is to vertical beam 11 on internal locking first.
Intensity of the present invention is big, and rubber ring difficult drop-off adapts to some adverse circumstances.
