Definitions
- the invention relates to a bearing ring with integrated cooling channels and a method for producing a bearing ring with integrated cooling channels.
- Bearing rings in aircraft engines are generally exposed to high roll-over loads and high operating temperatures. This applies in particular to bearing rings in main shaft bearings.
- materials for such bearing ring predominantly heat-resistant through hardening or case hardened steels, such as M50 (AMS 6491), M50NiL (AMS 6278), RBD, Pyrowear 675 (AMS 5930) are used.
- the heat dissipation from the contact areas is carried out by a continuous flow of oil.
- improved heat dissipation from the contact region can bring about an increase in performance of bearings, for example in the engine area.
- a heat dissipation is known for example from EP 2 503 107 B1, which describes a bearing arrangement for a turbomachine, wherein a bearing housing part with a coolant channel and a bearing housing part are provided with a lubricant passage, wherein the coolant passage and the lubricant passage are fluidly separated from each other.
- a composite material is described from a bearing housing with integrated cooling channels in conjunction with a bearing shell.
- EP 2 503 107 B1 also permits heat dissipation from the contact region.
- the possibility of cooling is limited, since the channels through which the coolant flows are relatively far away from the contact surface, since the bearing shell must have a certain minimum thickness for reasons of strength.
- the production of the described composite is problematic.
- the object of the invention is therefore to provide bearing rings and a method for their production, wherein an effective heat dissipation from the contact area is possible.
- the bearing ring according to the invention comprises integrated internal cooling channels, which have a cross section which deviates from a circular shape.
- the cross section may be similar to a curved slot, triangle, semicircle, circular ring section or polygon.
- a cross-section which extends arcuately in a similar shape as the raceway to be cooled, so to speak nestled or adapted to the raceway shape.
- This shape increases the Heat transfer between the cooling channel and raceway. This inevitably also improves the strength of the bearing used in terms of speed, load capacity and temperature range.
- a more compact design is possible: Basically, a more compact design with the same external load leads to higher surface pressures in the rolling contacts. Associated with this are higher power losses generated in the rolling contacts and thus also higher thermal stresses on the bearing components.
- these higher temperatures can be compensated or even reduced with the present invention by means of the oil flow in the raceway-near cooling channels with a smoothened cross-sectional shape.
- a larger heat flow can be removed by the near-line introduction of the cooling channels and the optimized cross-sectional shape, this is the case with the arrangement of the cooling channels in the bearing seat diameter. Conversely, this means that there is a lower need for cooling fluid, so less oil flow and a smaller heat exchange surface is needed, i. a smaller cross-sectional area of the channel or a shorter cooling channel.
- the channel cross-section can vary over the course of the channel in terms of shape and area, whereby the heat exchange surface, the heat transfer coefficient and the flow rate of the coolant can be influenced.
- This targeted influencing of the heat transfer in the circumferential direction can be advantageous for the dissipation of the power losses in the pronounced radially loaded roller bearings load zone in the circumferential direction.
- special requirements for the structural strength of the rings can be taken into account.
- cooling channels in the immediate vicinity of the contact zone, or the running surface of the bearing ring are introduced in such a way that they are integrated directly in the material which forms the raceway.
- an effective dissipation of heat from the contact area by oil-flow channels is possible, which are located in the vicinity of the contact zones of the bearing rings.
- An introduction of cooling channels is not possible in this area with hitherto applied manufacturing processes.
- it is therefore provided to form the cooling channels during the molding of the bearing rings - preferably by a generative manufacturing method, such as laser melting, laser sintering or the like.
- the invention is therefore intended to use a powder of a low-carbon steel for the additive manufacturing process.
- the necessary hardness in the region of the raceways can then be achieved by subsequent surface hardening, for example by subsequent enrichment with carbon.
- Fig. 1 shows a cross section through a bearing ring 10 according to the invention with along the track 1 1 introduced channels 12th
- Fig. 2 shows a cross section through a lab with bearing rings according to the invention 10.
- the raceways (1 1) are different channels (12a, 12b, 12c, 12d, 12e) recognizable with different Qerterrorismsformen.
