Abstract
The invention provides a filling type roller and a corresponding roller bearing based on the same. The filling type roller comprises a roller outer ring and a roller core, wherein the roller outer ring is made of bearing alloy, such as bearing steel. The roller core is positioned inside the roller outer ring and is made of a damping material with a vibration absorbing performance, such as silicone rubber. According to the filling type roller provided by the invention, a traditional hollow roller is filled with the damping material with the vibration absorbing performance; and the filling type roller is applied to the roller bearing, so that the bearing capacity of the bearing can be ensured and favorable structure damping characteristic can be obtained, and further the vibration and noise of the bearing are reduced.
Description
Technical field
The present invention relates to roller and roller bearing.
Background technique
The vibration and noise reducing of roller bearing is the bearing industry problem demanding prompt solution.
Hollow roller bearing can reach the purpose of vibration and noise reducing to a certain extent.Traditional solid roller is become hollow roller, can design hollow roller bearing.(US:595328 1897-12-14) makes the helicoidal structure by the sheet metal coil coiled with roller to U. S. Patent " Roller bearing ".(US:785944 1905-03-28) has invented a kind of thin-walled hollow roller bearing to U. S. Patent " Roller bearing ".(US:828387 1906-08-14) offers some sulculuses to U. S. Patent " Flexible roller for roller bearings " on thin-walled tubulose roller, invented a kind of flexible hollow roller bearing that has more.(French:946559 1949-06-08) has invented the hollow roller bearing that a kind of use preloads to F.P. " Roller bearing with preloaded hollow rollers ".U. S. Patent " Method of forming a roller bearing of superior runout characteristics " (US:3765071; What 1973-10-16) use also is hollow roller; Compare with the solid cylinder roller bearing; This bearing has little circular runout, can bear certain impulsive load.
These bearings all are to utilize the distortion of hollow roller to reach the purpose of some vibration and noise reducings, but the load of being born is not so good as the solid roller bearing of same size and material, and too simple mechanical structure has also limited it and further reduced vibration and anti noise.
Summary of the invention
For solving these deficiencies, the present invention provides a kind of filling type roller and corresponding roller bearing based on the filling type roller, and the technical problem that solve is under the demands for bearing capacity that guarantees bearing, further to reduce bearing vibration and noise.
The present invention adopts following technical proposals to realize: to existing hollow roller, the present invention provides a kind of filling type roller, and said roller comprises roller outer ring and roller core, and the roller outer ring adopts bearing alloy material to process, like Bearing Steel.It is inner that the roller core is positioned at the roller outer ring, is to be processed by the damping material with absorbing performance, like silicone rubber.
The roller that the present invention relates to both can be a cylindrical body, also can be Rotary-table.The shape of said roller core both can be a cylindrical body, also can be Rotary-table.
The invention has the beneficial effects as follows: filling type roller provided by the invention is at the inner damping material with absorbing performance of filling of traditional hollow roller; Be applied among the roller bearing; Can guarantee the bearing capacity of bearing; Good structural damping characteristic be can obtain again, thereby bearing vibration and noise reduced.

Embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 has schematically provided the structural representation of the roller bearing of first embodiment of the invention.Fig. 2 to Fig. 3 has further provided the structural representation of said roller.Wherein roller 1 is a cylindrical body, comprises roller outer ring 11 and roller core 12, and roller outer ring 11 is processed by Bearing Steel, and roller core 12 is processed by methyl vinyl silicone rubber, and roller core 12 is positioned at 11 inside, roller outer ring.Said roller core 12 be shaped as the cylindrical body that has identical medial axis with roller 1.The roller bearing based on the filling type roller that constitutes thus has the favorable damping anti-acoustic capability.
Shown in Figure 4 be in the second embodiment of the invention roller along the axis side cross sectional view.Compare with first embodiment, in the present embodiment roller core 12 be shaped as with present embodiment in roller 1 have the Rotary-table of identical medial axis.
Shown in Figure 5 be in the third embodiment of the invention roller along the axis side cross sectional view.Compare with first embodiment, roller 1 is a Rotary-table in the present embodiment, roller core 12 be shaped as with present embodiment in roller 1 have the Rotary-table of identical medial axis.
Shown in Figure 6 be in the four embodiment of the invention roller along the axis side cross sectional view.Compare with the 3rd embodiment, in the present embodiment roller core 12 be shaped as with present embodiment in roller 1 have the cylindrical body of identical medial axis.
Certainly, the present invention is not limited to above several embodiment.The material of roller outer ring also comprises other bearing alloy material that it will be apparent to those skilled in the art that; The material of roller core comprises that also other that it will be apparent to those skilled in the art that has the damping material of absorbing performance, for example the silicone rubber of other kinds or other absorbing materials.The roller bearing that the present invention relates to simultaneously both can be a roller bearing, also can be tapered roller bearing.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
