Abstract
The lubricating and sealing unit for support roller of belt conveyer consists of bearing seat and bearing set inside the bearing seat. Inside the bearing seat, there are two sealing parts on two sides of the bearing separately, and each sealing part has at least one elastic ring sealing lip in the inner side, ring notch in the side near the bearing, lubricating grease in the gap between the sealing part and the bearing, and one cover plate outside the bearing seat to seal the bearing seat. The sealing part has one inside spiral sealing lip, and two spiral sealing lips of the two sealing parts are opposite in direction. The sealing parts can supply grease to two sides of the bearing, their ring sealing lips prevent grease from leaking, the cover plate prevents dust from entering inside, and the opposite spiral sealing lips make the support roller carry grease toward the bearing while further preventing grease leaking.
Description
Technical field:
The present invention relates to belt conveyer, relate in particular to the carrying roller in the belt conveyer, particularly a kind of lubricating and sealing device of belt conveyer Idler bearing.
Background technology:
In the prior art, the Idler bearing of belt conveyer is realized sealing by seal ring usually, in use usually makes the bearing seal structure leakage of oil because sealing effectiveness is bad, and then the life-span of carrying roller is significantly reduced; In addition; grease is inhomogeneous to the bearing supply; the anti-dust performance of bearing seal structure is bad; usually have dust and enter into bearing seal structure; make bearing impaired, increase the resistance of carrying roller, simultaneously; seal ring because wear and tear, expand with heat and contract with cold, the reasons such as axial runout of carrying roller can cause sealing incomplete, make oil leak.
Summary of the invention:
Technical matters of the prior art to be solved by this invention is: because in the prior art, the Idler bearing of belt conveyer is realized sealing by seal ring usually, in use usually make the bearing seal structure leakage of oil, and then the life-span of carrying roller is significantly reduced because sealing effectiveness is bad; In addition; grease is inhomogeneous to the bearing supply; the anti-dust performance of bearing seal structure is bad; usually have dust and enter into bearing seal structure; make bearing impaired, increase the resistance of carrying roller, simultaneously; seal ring because wear and tear, expand with heat and contract with cold, the reasons such as axial runout of carrying roller can cause sealing incomplete, make oil leak.。
The present invention provides a kind of lubricating and sealing device of belt conveyer Idler bearing for the technical scheme that above-mentioned technical matters adopted in the solution prior art, the lubricating and sealing device of described this belt conveyer Idler bearing is made of bearing seat and bearing, described bearing is arranged in the described bearing seat, wherein, in described bearing seat, be provided with two sealing members, described two sealing members lay respectively at the both sides of described bearing, the inboard of any one described sealing member is provided with at least one annular seal lip, described annular seal lip has elasticity, be provided with annular groove in any one described sealing member side adjacent with described bearing, be provided with grease in the gap between any one described sealing member and the described bearing, the outer end of described bearing seat is provided with a cover plate, the edge of described cover plate and the inner seal of described bearing seat.
Further, the inboard of any one described sealing member is provided with a helix sealing lip, described helix sealing lip is between described annular seal lip and described bearing, and the hand of spiral of the helix sealing lip of described two sealing member inboards is opposite.
Further, the centre of described cover plate is provided with flange, and described cover plate is disc.
Further, the inboard, outer end of described bearing seat is provided with the kayser piece, and described kayser piece is fixed described cover plate.
Described sealing member can adopt material manufacture such as rubber, nylon or polytetrafluoroethylene.
The present invention and prior art contrast, and effect is positive and tangible.The present invention all is provided with the sealing member with elastic ring sealing lip in the both sides of bearing, be provided with oil resevoir in the sealing member again, so can be to the even fuel feeding in the both sides of bearing, and effectively prevent the leakage of lubricating grease, while cover plate and bearing seat inner seal, prevent that effectively dust from entering, in addition, with of the direction setting of helix sealing lip according to the carrying roller rotation, the spiral working direction that makes two helix sealing lips in opposite directions, rely on the viscosity of lubricating grease, carrying roller can be constantly with the lubricating grease band to the bearing direction, further prevent the leakage of lubricating grease.
