Abstract
The utility model discloses a thrust spherical plain bearing race, which relates to the field of thrust spherical plain bearings. The race is a circular race body, the outer circumferential surface of the race body is provided with a circular arc-shaped raceway surface, which is raised from the inside to the outside, the raceway surface is provided with a hardened layer which is formed by the hammering of a high-frequency hammer, the hardened layer is 1.5mm to 2.0mm thick, and the surface roughness value Ra of the hardened layer is equal to or less than 0.1Mum. The structure of the thrust spherical plain bearing race is simple, the arrangement of the raceway surface is reasonable, and the thrust spherical plain bearing race better solves the problems of a bearing, such as low rotation precision and easy abrasion, can better bear the axial load, and prolongs the service life of the bearing.
Description
Technical field
The utility model relates to a kind of thrust articulated bearing, specifically a kind of thrust articulated bearing blowout patche.
Background technique
At present, in the existing thrust articulated bearing processing, because the precision of bearing is mainly reflected on the raceway, particularly the roughness on the surface of raceway and accuracy to shape are the major criterions of weighing bearing accuracy and quality.Quenching processing technology behind the finish turning that China adopts at present, because the quenching phenomenon easily forms cold crack, and, quenching is used proper to thickness, the less part of diameter, for the bigger part of diameter, the depth of quenching is not enough, and therefore the bearing race after the processing is fragile.And thrust articulated bearing is owing to unreasonable structure in the prior art, and the set-up mode of its roller surface and roughness all do not reach requirement, therefore causes the lower and quick abrasion of this kind bearing accuracy, increases the economic burden of enterprise virtually.
The model utility content
The purpose of this utility model provides a kind of thrust articulated bearing blowout patche, and it is simple in structure, and when improving the bearing running accuracy, improved more than 30% its working life.
The utility model is for realizing the model utility purpose, the technological scheme that adopts is: a kind of thrust articulated bearing blowout patche, be annular circle body, external peripheral surface at circle body is provided with the circular arc roller surface, this roller surface is projection from inside to outside, roller surface is provided with the hardened layer that the hammering of high frequency tup forms, and the thickness of this hardened layer is 1.5~2.0mm.
Hardened layer surface roughness Ra value described in the utility model≤0.1 μ m.
The beneficial effects of the utility model are:
1, the external peripheral surface of this thrust articulated bearing blowout patche is provided with the roller surface that is formed by the hammering of high frequency tup, and this kind structure has better guaranteed the running accuracy of this kind bearing, improves bearing working life.
2, this roller surface forms by the hammering of high frequency tup, therefore, roller surface is formed one deck hardened layer, adopt this technology can make the metal structure on raceway top layer fine and close more, the raceway roughness is promoted 3, and roughness Ra value can reach 0.1 μ m more than the grade, even reaches below the 0.1 μ m, the micro-penetration hardness of raceway face is improved more than 20%, improved the contact fatigue property of raceway.Thereby improved its bearing capacity more than 10%, bearing life improves more than 30%.

Fig. 2 is the structural representation of usage mode of the present utility model;
Mark among the figure: 1, circle body, 2, roller surface, 3, hardened layer, 4, seat ring, 5, blowout patche.
Embodiment
As seen from the figure, a kind of thrust articulated bearing blowout patche, be annular circle body, external peripheral surface at circle body 1 is provided with circular arc roller surface 2, this roller surface 2 is projection from inside to outside, and the protruding radian of roller surface 2 equates that roller surface 2 is provided with the hardened layer 3 that the hammering of high frequency tup forms, and the thickness of this hardened layer 3 is 1.5~2.0mm.
The surface roughness Ra value of hardened layer 3 described in the utility model≤0.1 μ m.
Fig. 2 is the structural representation of usage mode of the present utility model, has constituted thrust articulated bearing by blowout patche 5 and seat ring 4.
Roller surface described in the utility model is formed by the hammering of high frequency tup, is: the high frequency tup is the vibratory tool head, and this vibratory tool head carries out the hammering of ultra-high frequency to race way greater than 30,000 times vibration frequency with per second.The vibratory tool head is with the surface of the vibration hammering bearing race of high frequency, make the top layer metal structure of race way produce the plastic deformation of trace, it is smooth that the waviness of workpiece surface tends to further, thereby reach the surface quality of minute surface, this technology is to be media becomes radial spread in the metal surface a kind of quantum with the finish, its effect is to make the electronic shell of metallic material atom absorb this quantum, the electronic shell activity is more active, atomic nucleus is relative with the electronic shell combination force to diminish thereby cause, the combination force of atom and atom diminishes, metallic material plasticity under the effect of this quantum changes, and ductility improves.Adding frequency in addition again is the high frequency vibration of 30KHz, when vibration transducer detects the dither of amplitude 3-5 micron, promptly this state is an optimum Working, the micro-penetration hardness of raceway face improves more than 20% before the processing simultaneously, the roughness that the roughness ratio of raceway generally grinds out improves 3 more than the grade, roughness Ra value can reach 0.1 μ m, even reaches below the 0.1 μ m, and the more traditional abrasive process of work efficiency improves more than 50%.
The utility model, it is simple in structure, and roller surface is provided with rationally, has better solved difficult problems such as the bearing running accuracy is not high and easy to wear, can better bear axial load.
