Abstract

PURPOSE: To give a long service life to a roll bearing by applying galvanized zinc-base alloy coating at least to the rolling contact surfaces of the bearing. CONSTITUTION: The whole surfaces of an inner ring 2 and an outer ring 3 of the bearing are provided with corrosion protection coating 6 composed of a zinc-base alloy, preferably corrosion prevention coating 6 with 0.1-3.0 μm thickness comprising Zn-Ni, Zn-Fe or Zn-Co being applied also to inside walls of the grooved rolling contact surfaces 7, 8. The coating can be more than 3.0 μm in thickness with an upper limit of around 9.0 μm. The ductile alloy coating layer is pressed and set into cavities of rough surface of the rolling contact surfaces under load at the outermost margins. The excess of the coating layer is squeezed out from the pressed area of the rolling contact surfaces, and a highly corrosion resistant roll bearing can be obtained after a short break-in.

低下するのではなく改善される。According to the invention, according to the invention, at least the rolling surface is provided with a corrosion-inhibiting coating of electroplated zinc alloy. Has been resolved by Such semi-hard coatings on the rolling surfaces and possibly other surfaces of the rolling bearings result in very effective corrosion protection. In this case, for example, a load accompanied by friction due to overrolling of rolling elements does not give a negative result to the service life of the coating.
That is, under the above-mentioned load at the outermost edge, the malleable alloy coating layer is pressed into the troughs of the surface roughness existing on the rolling surface and is fixed thereto. The excess coating layer is squeezed out of the compression zone of the rolling surface during operation. This results in a fully functioning rolling bearing with high corrosion protection after a short break-in, which takes place in only a few cycles. The rolling-fatigue strength is determined by the press-fitting process into the valley of the surface roughness described above.
It improves rather than decreases.

It is known from DE-GBM 90 05 28. This radial rolling bearing has flange plates on both sides of the row of rolling elements, in which case the radial packing ring fixed to the outer ring is in contact with the outer periphery of each flange plate by its lip-shaped sealing strip. Moreover, the lip-shaped sealing strips, in another construction variant of the radial rolling bearing, which is not illustrated in the above-mentioned publication, are adapted to bear directly on the outer circumference of the inner ring, as is known. When the outer surface of such a radial rolling bearing is exposed to a liquid that corrodes a portion made of steel, a particular problem occurs when the lip seal strips of the radial packing ring are corroded. That is, in this case, the radial packing can no longer perform its function and the bearing is damaged in a relatively short time.

い。According to yet another aspect of the present invention as set forth in claim 6, the corrosion protection coating has a thickness of 0.1 to 3.0 μm.
It has a layer thickness of up to. The coating material of this layer thickness moves within the range of the surface roughness of the rolling bearing structure. This allows the electroplating layer to penetrate completely into the profile of the surface roughness during the operation of the rolling bearing and thus not adversely affect the tolerances of the structural parts. Due to the very fine wear within the surface roughness of the rolling tracks, the layer particles are pressed in, which increase the rust protection of the rolling tracks and thus of the rolling bearing and give rise to a kind of emergency operation or dry lubrication. Since the coating layer thickness is small, there is little pollution to the environment.

With such layer thicknesses of the anticorrosion coating, it can be designed such that the service life of the anticorrosion coating is maximized under the action of high tribological loads.
Finally, according to claim 8, the corrosion protection coating has a yellow-chromate treatment layer as an upper layer. The nickel content in the zinc coating is increased by approximately 60 HV to 300 HV, i.e. the wear resistance of the coating by several times, by virtue of the iron content and the structure with this chromate treatment layer.

食防止作用を示しかつ長い耐用寿命を有している。In FIG. 2, a double-row cylindrical roller bearing is indicated by reference numeral 9, and the double-row cylindrical roller bearing is composed of an inner ring 10 and an outer ring 11 concentrically arranged with respect to the inner ring 10.
The inner and outer wheels 10 and 11 have rolling surfaces 12 and 13 facing each other, and two rows of cylindrical rolling elements 14 are arranged between the rolling surfaces 12 and 13. The outer ring 11 is provided with a flange 15 for guiding the cylindrical rolling element 14.
And 16 are provided, the cylindrical rolling elements of both rows are provided with angle-shaped flange plates 17 and 18 in the inner ring 10.
Being guided by. This flange plate 17 and 1
8 has a corresponding surface 19 formed on its outer circumference for the radial packing rings 20 and 21. Each of these radial packing rings 20 and 21 is fitted on the outer ring 11 by being sealed at the outer periphery and has one lip-shaped sealing strip 22, each of which has a lip-shaped sealing strip.
With the elastically loaded preload, it slides on the corresponding surface 19 of each flange plate 17 or 18. According to the invention, the counter surface 19 is provided with a corrosion-inhibiting coating 23 of zinc-nickel-alloy, which also preferably has a coating layer thickness of 0.1 μm to 3.0 μm. ing. This coating layer thickness, however, can be up to 9.0 μm. This corrosion-inhibiting coating on the corresponding surface prevents corrosion below the radial packing rings 20 and 21.
Otherwise, this corrosion will destroy the hermeticity of the double row cylindrical roller bearing. The zinc-nickel coating, for example, provided on the counter surface 19 exhibits a good corrosion protection and has a long service life.
