Abstract
The utility model relates to a carrying roller bearing lubricating and sealing structure for the belt conveyer, comprising a bearing seat and a bearing. The bearing is arranged in the bearing seat whose interior is provide with two sealing elements which are located respectively on the both sides of the bearing. The interiors of the sealing elements are all provided with at least one annular sealing lip having elasticity. The annular grooves are equipped all in one side where sealing elements are adjacent to the bearing, and the lubricating grease is all equipped in the gap parts between the sealing elements and the bearing. The external end of the bearing seat is provided with a cover plate which is sealed with the bearing seat. The internal side of the sealing element is provided with a spiral sealing lip, and the spiral directions of the spiral seal lips in the internal sides of the two sealing elements are opposite. The sealing elements can supply the oil for the both sides of the bearing uniformly; the annular sealing lips can prevent from the leakage of the lubricating grease; the cover plate avoids the entrance of the dust. The spiral heading directions of the two spiral sealing lip are opposite, and the carrying roller takes the grease to the direction of the bearing, depending on the viscosity of the grease; consequently, the leakage of the lubricating grease is prevented further.
Description
Technical field:
The utility model relates to belt conveyer, relates in particular to the carrying roller in the belt conveyer, particularly a kind of Idler bearing lubrication sealing structure that is used for belt conveyer.
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 in the utility model 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 utility model provides a kind of Idler bearing lubrication sealing structure that is used for belt conveyer for the technical scheme that above-mentioned technical matters adopted that solves in the prior art, the described this Idler bearing lubrication sealing structure that is used for belt conveyer 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 utility model and prior art contrast, and effect is positive and tangible.The utility model 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.
