Abstract
The invention discloses a low-noise bearing which comprises an inner ring, an outer ring and a retainer, wherein the retainer is arranged between the outer ring and the inner ring; the retainer is axially provided with two baffle rings; isolating blocks are uniformly distributed between the baffle rings; a gap is formed between end surfaces of adjacent isolating blocks; a seam bracket forms a rolling slot; a rolling post is arranged in the rolling slot; the isolating blocks and the two baffle rings form a ring-shaped structure; rolling slots are formed in the isolating blocks; rolling posts are arranged in the rolling slots; the outside of the rolling posts and the inner wall of the outer ring form rolling fit; and the inner walls of the rolling posts and the outer wall of the inner ring form rolling fit. The low-noise bearing is novel in structure and reasonable in design; the rolling posts are arranged in the rolling slot, so that noises generated during rotation of the rolling posts can be effectively reduced, and therefore, bearing noises are reduced, heat dispersion is improved by virtue of the seams, deformation of the bearing rack is prevented, and service life of the bearing is prolonged.
Description
Technical field
The invention belongs to technical field of bearings, be specifically related to a kind of low noise bearing.
Background technique
Bearing is component conventional in mechanical rotation, existing bearing generally includes inner ring, outer ring and retainer, retainer comprises maintenance stand, retainer lid and roller, roller is connected to and keeps between stand and retainer lid, keep stand, retainer lid and roller all adopt metal material to make, the bearing of this kind of organization establishes, during Internal and external cycle work, drive roller high speed rotating, because the retainer lid of roller and both sides is all metal materials, therefore the noise producing noise is larger, and roller rotates for a long time, there is high temperature deformation in roller two ends frictional heat, affect the working life of retainer and bearing.
Summary of the invention
For problems of the prior art, the object of the invention is to design provides a kind of low noise bearing.
Described a kind of low noise bearing, comprise inner ring, outer ring, retainer, described retainer is arranged between outer ring and inner ring, described retainer is axially provided with two back-up rings, it is characterized in that uniformly between two back-up rings being provided with spacing block, gap is left between the end face of adjacent spacing block, described gap support forms rolling groove, rolling post is provided with in described rolling groove, ring structure is formed between described spacing block and two ribs, described spacing block is provided with slot rolling, roller is provided with in described slot rolling, the outside of described roller with between the inwall of outer ring and the inwall of roller coordinate with all being formed to roll between interior ring outer wall.
Described a kind of low noise bearing, it is characterized in that the lower end, both sides of described spacing block is respectively arranged with two lower stop edge, the upper end, both sides of each spacing block is respectively arranged with rib, described two lower stop edge fit respectively be arranged on both sides back-up ring inner hole wall on, lower stop edge is between back-up ring and inner ring, on two rib fit respectively be arranged on both sides back-up ring outside diameter wall on, between back-up ring and outer ring, and there is running clearance between lower stop edge and interior ring outer wall and between upper rib and outer ring outer wall in upper rib.
Described a kind of low noise bearing, is characterized in that described slot rolling is at least provided with one.
Described a kind of low noise bearing, is characterized in that described spacing block is connected through closing-up with two back-up rings, rivet through after back-up ring and spacing block with the back-up ring riveted on opposite.
Novel structure of the present invention, reasonable in design, by being arranged in slot rolling by roller, the noise sent when roller rotates effectively can be reduced, thus reduction bearing noise, by the gap arranged, improve heat dispersion, prevent the distortion of bearing bracket stand, thus extend the working life of bearing.

Embodiment
The present invention is further illustrated below in conjunction with Figure of description.
As Figure 1-4, a kind of low noise bearing of the present invention, comprise inner ring 1, outer ring 2, retainer 3, retainer 3 is arranged between outer ring 2 and inner ring 1, retainer 3 is axially provided with two back-up rings 4, uniformly between two back-up rings 4 be provided with spacing block 5, spacing block 5 is connected through closing-up with two back-up rings 4, rivet through after back-up ring and spacing block with the back-up ring riveted on opposite, the material of spacing block is PA66 or PA46 or PEEK, for improving heat dispersion, gap is left between the end face of adjacent spacing block 5, for improving the load capacity of bearing, rolling groove 6 is formed between gap, rolling post 7 is provided with in rolling groove 6, ring structure is formed between spacing block 5 and two back-up rings 4, spacing block 5 is provided with at least one slot rolling 8, roller 9 is provided with in slot rolling 8, the outside of roller 9 with between the inwall of outer ring 2 and the inwall of roller 9 coordinate with all being formed to roll between inner ring 1 outer wall.
The lower end, both sides of spacing block 5 is respectively arranged with two lower stop edge 10, the upper end, both sides of each spacing block 5 is respectively arranged with rib 11, two lower stop edge 10 are fitted respectively and are arranged on the inner hole wall of both sides back-up ring 4, lower stop edge 10 is between back-up ring 4 and inner ring 1, on two, rib 11 is fitted respectively and is arranged in the outside diameter wall of both sides back-up ring 4, between back-up ring 4 and outer ring 2, and there is running clearance between lower stop edge 10 and inner ring 1 outer wall and between upper rib 11 and outer ring 2 outer wall in upper rib 11.
Each spacing block 5 adopts same mould die sinking to make, and can guarantee the precision of retainer, and by some pieces of isolation, 5 combinations are arranged between two back-up rings 4, and more increasing retainer can done, diameter even can accomplish more than 1 meter.Bearing of the present invention is suitable for inner ring 1 and guides, when inner ring 1 high speed rotating, spacing block 5 can be outwards mobile, relies on the rib of spacing block both sides and coordinating between back-up ring inner hole wall now, effectively can limit the outside movement of spacing block, improve spacing block and coordinate intensity between back-up ring.
