In preferred embodiment of the utility model, the material of described lasso body comprises one of Bearing Steel, 45 steel, 40Cr, 20 steel.
In preferred embodiment of the utility model, the width of described groove is the 50%-70% of the length of the roller that is mounted thereon.
In preferred embodiment of the utility model, described lasso body is roller bearing outer ring and/or roller bearing inner ring.
In preferred embodiment of the utility model, described roller bearing is single-row roller bearing, and described groove has one, is positioned at the centre of described roller mounting point, and plating has ceramic layer in the described groove.
In preferred embodiment of the utility model, described roller bearing is the multiple row roller bearing, the bar number of described groove equals the columns of described roller bearing, and every described groove is positioned at the centre of every row roller mounting point, and equal plating has ceramic layer in the described groove.
The beneficial effects of the utility model are: offer groove by the special position at the rolling surface of lasso body, and in groove the plating stupalith, make engineering ceramic material contact work with roller, the wearing and tearing of lasso working surface have been reduced effectively, the pattern that reduces the surface worsens, thereby prolongs the working life of bearing; And the metal rolling surface that leaves certain width at the surperficial two ends of ceramic layer contacts with roller, make it bear main impulsive load, it is big to have overcome engineering ceramic material fragility, fragile, shortcomings such as impact resistance is low, the requirement of strength when having guaranteed bearing working effectively.

The mark of each parts is as follows in the accompanying drawing: 1-1, lasso body, 1-2, rolling surface, 1-3, roller, 1-4, groove, 1-5, ceramic layer; 2-1, lasso body, 2-2, rolling surface, 2-3, roller, 2-4, groove, 2-5, ceramic layer.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Embodiment one:
See also Fig. 1, the utility model comprises:
A kind of roller bearing ferrule surface structure, described roller bearing is single-row roller bearing, comprise lasso body 1-1, contain rolling surface 1-2 on the described lasso body 1-1, be used for a row roller 1-3 is installed, offer a groove 1-4 on the described rolling surface 1-2, described groove 1-4 is positioned at the centre of described roller 1-3 mounting point, and plating has ceramic layer 1-5 in the described groove 1-4, and the outer surface of described ceramic layer 1-5 is concordant with described rolling surface 1-2.
Wherein, the material of described lasso body 1-1 is a kind of in the metallic material such as Bearing Steel, 45 steel, 40Cr or 20 steel.
The width of described groove 1-4 is the 50%-70% of the roller 1-3 length that is mounted thereon, is preferably 60% of roller 1-3 length.
Described lasso body 1-1 is roller bearing outer ring and/or roller bearing inner ring.
Embodiment two:
See also Fig. 2, the utility model comprises:
A kind of roller bearing ferrule surface structure, described roller bearing is double-row roller bearing, comprise lasso body 2-1, contain rolling surface 2-2 on the described lasso body 2-1, be used for two row roller 2-3 are installed, offer two groove 2-4 on the described rolling surface 2-2, lay respectively at the centre of the described roller 2-3 of every row mounting point, and equal plating has ceramic layer 2-5 in every described groove 2-4, and the outer surface of described ceramic layer 2-5 is concordant with described rolling surface 2-2.
