Definitions

  • the invention is related to the field of finishing the surface of a rolling contact component.
  • a rolling contact component can form part of a rolling element bearing, e.g. a bearing ring or a ball-type or roller-type rolling element.
  • components which form part of a rolling traction drive are encompassed, e.g. the power rollers and discs of an infinitively or continuously variable transmission.
  • a proportioning and strengthening of the surface in question is obtained by means of a ball calendering (burnishing) tool which plastically deforms the roughness peaks which are left behind after a hard turning or rough grinding operation.
  • the tool comprises a holder at the tip of which a ball is usually rotatably supported by means of a pressure fluid.
  • the calendering ball has a diameter of 2 mm to 13 mm.
  • a method of this type for manufacturing a traction drive rolling element has been disclosed in Japanese patent application JP-A-9137854. According to this prior art method, a surface pressures of 7 GPa or higher is applied. As a result, compressive residual stresses are obtained beneath the surface thus treated which lead to an increase of the rolling fatigue resistance and which would prevent the surface layers from flaking off. The method in question is claimed to generate compressive stresses of about 1.5 GPa at a depth of 0.1 - 0.2 mm beneath the surface.
  • the object of the present invention is therefore to provide a method for finishing a surface of a rolling contact component which combines excellent tribological propertied with a long contact fatigue life, good scuffing resistance and a good ability to build up a lubricant film.
  • a method for finishing the surface of a rolling contact component such as a bearing rolling element, a bearing ring or a traction drive rolling element, comprising the steps of: carrying out a cutting operation on the surface, - subsequently calendering or burnishing the surface by means of a ball comprising a material harder than the rolling contact component material whereby the maximum calendering or burnishing pressure exerted on the surface is less than 7 GPa.
  • the calendering or burnishing pressure By controlling the calendering or burnishing pressure at values less than 7 GPa, first of all the desired pattern or texture of flattened areas or lands is obtained, which areas are separated from each other by grooves. The flattened areas have the same height, which results in a balanced load sharing ability.
  • the limitation of the calendering pressure provides reduced residual surface and sub-surface compressive stresses, which leads to an extended life.
  • compressive stresses are generated at and/or beneath the surface, which compressive stresses do not exceed 1 GPa absolute.
  • the compressive stresses do not exceed 0.8 GPa absolute. Since the surface of the component in question has been overrolled and thereby plastically deformed, it can be expected that the running in takes place already at the manufacturing stage. The bearing therefore does not require running in.
  • the process in question can be carried out in a quick and cost-effective manner by combining the (hard) cutting operation and the calendering operation in a single pass turning process.
  • the calendering ball may either be of a rolling type or of a sliding type. Furthermore, specific surface portions may be exposed to the calendering or burnishing pressure for more than one time.
  • Figure 1 shows a state of the art surface obtained by grinding.
  • Figure 2 shows a surface obtained according to the method of the invention.
  • the surface shown in figure 1, e.g. of a bearing ring or power roller, has been obtained by a cutting operation and subsequent grinding.
  • the surface has a regular pattern of grooves 2 and ridges 1 , providing ISO reference of R A 0.2 ⁇ m.
  • the roughness R A in general is 0.27 whereas the roughness on the areas (which need not to be fully flat) is R A 0.1 microns.
  • the surface and sub-surface residual compresses stresses are less than 0.8 GPa.
