Abstract
The invention relates to a double-lip sealing cover for a roller linear guide rail pair. The invention has the technical scheme that the double-lip sealing cover for the roller linear guide rail pair comprises a metal plate substrate, a rubber layer with a certain thickness is poured on the outer surface of the metal plate substrate, the sealing surface on the metal plate substrate is in the same shape as that of the roller path surface of a guide rail, a front lip sealing body and a back lip sealing body are arranged on the sealing surface, and included angles are formed between the front lip sealing body and the sealing surface as well as between the back lip sealing body and the sealing surface. The double-lip sealing cover has the beneficial effects that the double-lip sealing cover can effectively prevent dust and foreign matters from entering a moving surface so that a slide block more steadily moves, and the double-lip sealing cover has better precision retentivity and longer service life.
Description
Technical field
The present invention relates to a kind of sealed member, relate in particular to a kind of roller line slideway auxiliary and cover with double-lip seal.
Background technique
Because roller line slideway auxiliary is a kind of new-type rolling functional part of developing both at home and abroad in recent years, along with developing rapidly of equipment manufacture, people are also more and more higher to the performance requirement of rolling function parts, when guaranteeing running precision, also will guarantee its life-span.
In the present linear rolling guide, the sealing position of use is simple single procheilon structure, and sealing effect is not good enough, is difficult for realizing high-speed motion; And the novel outstanding feature of this use is exactly to guarantee the long life-span, realizes high-speed motion, allows that maximum speed can reach 120m/min, allows that high-acceleration can reach 2G.
Summary of the invention
The present invention be directed to the existing in prior technology shortcoming, and provide a kind of roller line slideway auxiliary to cover with double-lip seal, it not only can isolate dust and foreign matter effectively, and has the function that prevents that grease runs off, and is easy to install.
The present invention realizes by following technical measures: a kind of roller line slideway auxiliary covers with double-lip seal, it comprises the sheet metal matrix, described sheet metal outer surface of matrix is cast with certain thickness rubber layer, the shape of sealing surface is identical with the roller surface shape of guide rail on the described sheet metal matrix, described sealing surface is provided with anterior lip seal and posterior lip seal, between described anterior lip seal and posterior lip seal and the sealing surface certain angle is arranged.
Concrete characteristics of the present invention also have, and above-mentioned sheet metal matrix is provided with mounting hole.
Angle α between above-mentioned anterior lip seal and the sealing surface is that the angle β between 30 degree and posterior lip seal and the sealing surface is 60 degree.
The beneficial effect of this programme can learn that it can prevent effectively that dust and foreign matter from entering moving surface, makes slide block movement more steady according to the narration to such scheme, and precision stability is better, and the life-span is longer.

Embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by an embodiment.
As shown in the figure, a kind of roller line slideway auxiliary covers with double-lip seal, it comprises sheet metal matrix 4, described sheet metal matrix 4 outer surfaces are cast with certain thickness rubber layer 3, what specifically adopt is the nitrile butadiene rubber layer, the shape of sealing surface 5 is identical with the roller surface shape of guide rail on the described sheet metal matrix 4, described sealing surface 5 is provided with anterior lip seal 1 and posterior lip seal 2, between described anterior lip seal 1 and posterior lip seal 2 and the sealing surface 5 certain angle is arranged, wherein, the angle α between anterior lip seal 1 and the sealing surface 5 is that the angle β between 30 degree and posterior lip seal 2 and the sealing surface 5 is 60 degree.Sheet metal matrix 4 is provided with mounting hole.
The present invention can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
