Definitions
- the invention relates to a method for treating a component and to an apparatus for carrying out the method.
- Rolling bearing surfaces are susceptible to cracking under certain tribological loading conditions. In this case, crack initiation, possibly supported by tribochrome, takes place, unlike classical rolling fatigue on the raceway surface itself and crack propagation in such a way that the affected surface layers flake off. This mechanism is particularly important for bearings designed for long run times.
- An object of the present invention is to provide a method for treating a mechanically, in particular dynamically, tribologically and / or corrosively stressed component so that the longest possible service lives are achieved.
- a method for treating a component comprising a material of crystalline, semi-crystalline or amorphous structure, that is to say in particular metallic or ceramic, for a surface layer, ie a Refining a near-surface region at least a portion of a surface of the component is blasted with an oil jet, wherein the oil blasting is performed with a tempered oil and / or the component is tempered.
- the invention is based on the recognition that in cyclic loading of a component made of a material of crystalline, semi-crystalline or amorphous structure, in the case of ceramic, e.g. tension-controlled, surface cracks can occur with pitting, which comes especially in case of a surface emanating from the surface failure of a metallic component in the course of damage to a mechanically induced degradation of the compressive residual stresses.
- residual compressive stresses are built up in the highly stressed edge layer of the treated component, which counteract the crack initiation and propagation and delay it.
- the invention is based on the finding that with cyclic loading of a metallic component, for example, the above-described rolling over of the race by the rolling elements, the increasingly in operation increasing mobility of dislocations of the material as an important mechanism of material fatigue of metallic materials essential for material aging (initially without metallographically detectable structural transformation) and thus ultimately contributes to the failure of the component.
- a metallic component for example, the above-described rolling over of the race by the rolling elements
- the increasingly in operation increasing mobility of dislocations of the material as an important mechanism of material fatigue of metallic materials essential for material aging (initially without metallographically detectable structural transformation) and thus ultimately contributes to the failure of the component.
- an energetically favorable state of said dislocations is stabilized via dynamic strain aging processes, thereby increasing the service life.
- a built-up, crack-inhibiting compressive residual stress state is stabilized without a decrease in magnitude.
- the interstitially dissolved carbon in the lattice becomes mobile and can diffuse to form the so-called Cottrell clouds to the dislocation nuclei, which is also referred to as segregation.
- This atomic arrangement is energetically favored and therefore counteracts the operation of the rolling bearing of the incipient dislocation movements. This increases the service life of the rolling bearing.
- Suitable temperatures for the hot oil blasting are dependent on
- a martensitic through- or surface hardened (eg case hardening or induction hardening) rolling bearing steel is the typical range between 100 0 C and 220 0 C, whereas, for example, for a bainitic steel between 100 0 C and 300 0 C are favorable.
- the temperature is of course chosen in consideration of the respective dimensional stability requirements of the race. If the ring is heated inductively or in the oven, a higher temperature can be selected for a short time (eg over 10 minutes). Depending on the temperature and the particular design of a system for carrying out the hot oil blasting is blasted for about 1 to 30 minutes. As a jet oil while a suitable, especially a correspondingly temperature-resistant oil is used.
- the oil blasting is preferably used as the last processing step following a heat treatment and / or a fine machining, such as hard turning, finish turning, grinding and honing, but can also mechanical post-processing with only limited material removal (eg honing) for setting a desired surface quality respectively.
- a suitable mechanical machining method eg hard turning
- An apparatus for performing the hot oil blasting includes holding means for holding the rolling bearing ring during irradiation, and emitting means for discharging the oil jet.
- the holding means are formed, for example, for an inner race such that they hold the race inside and for a complete blasting of arranged on the outer surface of the raceway raceway rotate past the track on the radiating means and also allow movement in the direction of the main axis of the race.
- the emission means comprise at least one nozzle, in particular in a design as a gap nozzle.
- the device comprises heating means for tempering the oil and / or the race by means of inductive heating or an oven. In other embodiments, of course, the emission means may be designed to be movable at least in one spatial direction.
- the device may also, in particular by a suitable housing, allow oil jets under a protective gas atmosphere (eg nitrogen flow).
- Rolling with races and / or rolling elements which are produced by the method described above, are used with particular advantage, for example in transmissions.
