Abstract
The invention discloses a kind of bearing sealed ring, comprise the steel ring skeleton in outside and the rubber ring of inner side, described steel ring skeleton comprises back timber and vertical beam one and bottom girder, described back timber is horizontally disposed with, one section, the centre of described vertical beam one bends in 45 °, the C type portion that described rubber ring comprises vertical beam two and is connected with vertical beam two, described vertical beam two bonds together with the hypomere of the vertical beam one of steel ring skeleton, the described top in C type portion and the bottom girder of steel ring skeleton bond together, the bottom in described C type portion is sealing lip, described sealing lip and horizontal angle 30 °≤α≤70 °.The invention can increase the elastic strain ability of seal ring, increases the service life, and can increase the clamping ability that seal ring and bearing outer ring seal notch simultaneously, and facilitate the installation of bearing sealed ring.
Description
Technical field
The present invention relates to a kind of bearing sealed ring, especially a kind of Automobile drive bearing seal ring.
Background technique
Bearing sealed ring is the main seal part in bearing, is not only kept in bearing by lubricating grease, prevents again foreign debris or dust from entering in bearing simultaneously, effectively can improve the working life of bearing.
In the past, bearing sealed ring entirety was made up of rubber, but the bearing sealed ring intensity be all made up of rubber is little, in order to improve the intensity of bearing sealed ring, usually can be embedded in steel ring skeleton in the rubber body of bearing sealed ring.
After embedding steel ring skeleton, the intensity of bearing sealed ring is greatly improved really, but, along with the lifting of intensity, the elastic strain ability of bearing sealed ring receives weakening, such one is the assembling difficulty increasing bearing sealed ring, two is be difficult to control the magnitude of interference between sealing lip and bearing ring, because, when magnitude of interference changes, if elastic strain ability is strong, frictional force between sealing lip and bearing ring can't notable change, but, if elastic strain ability is weak, magnitude of interference slightly changes, frictional force between sealing lip and bearing ring will notable change, frictional force one is large, significantly will affect working life, frictional force is too little, then sealability can reduce.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of bearing sealed ring that can increase elastic strain ability.For addressing these problems, the present invention by the following technical solutions:
A kind of bearing sealed ring, comprise the steel ring skeleton in outside and the rubber ring of inner side, described steel ring skeleton comprises back timber, vertical beam one and bottom girder, described back timber is horizontally disposed with, one section, centre and the horizontal line of described vertical beam one are 45 ° and bend, the C type portion that described rubber ring comprises vertical beam two and is connected with vertical beam two, described vertical beam two bonds together with the hypomere of the vertical beam one of steel ring skeleton, the described top in C type portion and the bottom girder of steel ring skeleton bond together, the bottom in described C type portion is sealing lip, described sealing lip and horizontal angle 30 °≤α≤70 °.
Technical characterstic of the present invention is also: the outer end of described back timber is C-shaped bending, and described back timber and vertical beam one joint seamlessly transit.
Adopt above technological scheme, the present invention has the following advantages:
1. one section, the centre of steel ring skeleton vertical beam one of the present invention bends in 45 °, and this is when ensure that its intensity, can increase the elastic strain ability of steel ring skeleton as far as possible, facilitates lathe to be pressed into simultaneously, ensure that the Geometrical Tolerance Principle after seal ring press-in.
2. the vertical beam two of rubber ring of the present invention connects a C type portion, the bottom in described C type portion is sealing lip, described sealing lip and horizontal angle 30 °≤α≤70 °, such structure considerably increases the elastic strain ability of sealing lip, and after sealing lip wearing and tearing, due to this elastically-deformable reaction, sealing lip still can well with bearing ring interference fit, increase the service life.
The top in 3.C type portion and the bottom girder of steel ring skeleton bond together, and C type portion's elastic strain of rubber ring can be prevented so too large, and affect the sealability of bearing sealed ring.
4. the outer end of back timber of the present invention is C-shaped bending, and back timber and vertical beam one joint seamlessly transit, and can increase the elasticity of steel ring skeleton as far as possible, facilitate the installation of bearing sealed ring, and increase steel ring skeleton and bearing outer ring seal the clamping ability between notch simultaneously.
Accompanying drawing explanation
Fig. 1 is the cut-away view that bearing sealed ring of the present invention and bearing ring fit together.
Fig. 2 is the enlarged diagram of sectional view upper half part that seal ring and bearing ring fit together.
Fig. 3 is the sectional view (only upper half part being shown) of bearing sealed ring of the present invention
Number in the figure: the outer end of 1 steel ring skeleton, 2 rubber rings, 11 back timbers, 111 back timbers, 112 back timbers and vertical beam one joint, one section, the centre of 12 vertical beam one, 121 vertical beams one, the hypomere of 122 vertical beams one, 13 bottom girders, 21 vertical beam two, 22 C type portions, the top in 221 C type portions, 3 sealing lips.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation:
Embodiment 1: a kind of bearing sealed ring as shown in Figure 1, comprise the steel ring skeleton 1 in outside and the rubber ring 2 of inner side, described steel ring skeleton comprises back timber 11, vertical beam 1 and bottom girder 13, described back timber 11 is horizontally disposed with, the outer end 111 of described back timber is C-shaped bending, and described back timber and vertical beam one joint 112 seamlessly transit.The centre of described vertical beam 1 bends in 45 ° for one section 121, the C type portion 22 that described rubber ring comprises vertical beam 2 21 and is connected with vertical beam two, described vertical beam 2 21 bonds together with the hypomere 122 of the vertical beam one of steel ring skeleton, the top 221 in described C type portion bonds together with the bottom girder 13 of steel ring skeleton, the bottom in described C type portion is sealing lip 3, described sealing lip 3 and horizontal angle 30 °≤α≤70 °.
Adopt above technological scheme, the present invention can increase the elastic strain ability of seal ring, increases the service life, and can increase the clamping ability that seal ring and bearing outer ring seal notch simultaneously, and facilitate the installation of bearing sealed ring, be applicable to the use of 88128/YA Automobile drive bearing.
