Detailed description of the invention
One enforcement modification of sliding bearing 1 is shown with side view in FIG with dissecting. Sliding bearing 1 is using the form of half-shell and constructs as double-deck sliding bearing 1. Sliding bearing 1 is particularly set to the cartridge housing of the lower section of sliding bearing.
But sliding bearing 1 can also have other shape. Sliding bearing 1 can be such as thrust ring.
Sliding bearing 1 includes metal layer on back 2 and other layer 3. Layer 3 additionally is arranged on the surface 4 of the inner radial of metal layer on back 2 and engages with described metal layer on back.
Metal layer on back 3 brings required structural stability to sliding bearing 1. It is made up of the material of the metal being suitable at this, particularly steel.
Layer 3 additionally constitutes the work surface 5 for component to be supported, particularly axle. Therefore, this other layer 3 implementing modification of sliding bearing 1 is sliding layer. It is made up of the bearing material of metal.
Except the enforcement modification of this bilayer of sliding bearing 1, implement modification and can also have the layer of more than two. Such as, layer 3 additionally can have coating, such as break-in coating on work surface 5. At least one other layer, such as bearing metal layer, diffusion impervious layer, the attached layer of increasing is arranged equally overleaf between metal level 2 and other layer 3.
Because by this embodiment that prior art discloses sliding bearing 1, may refer to relevant document for this for details.
Furthermore, it is possible to the other layer 3 as direct coating is coated be contained on component, such as in the tie rod holes of connecting rod, thus metal layer on back 2 is by described component itself, namely such as connecting rod is formed in this case.
Sliding bearing 1 has the hole 6 through metal layer on back 2 and other layer 3. Hole 6 is arranged thermocouple 7. Thermocouple 7 has two hardwares 8,9, and described hardware is connected to each other for 10 times in structure (in aforesaid meaning) thermally coupled on work surface 5 region. As this itself for thermocouple it is known that the two hardware 8,9 can be made up of metal and/or metal alloy, wherein, hardware 8 is made up of the metal material being different from hardware 9. Such as, hardware 8 is made up of nickel, and hardware 9 is made up of nichrome. But other the combination being made up of different metals and metal alloy can also be used, such as, there is the platinum of platinum-rhodium alloy or there is the ferrum of corronil.
Thermally coupled 10 plane earth and work surface 5 construct. Described thermally coupled extends from work surface along the direction of metal layer on back 2. Additionally, described hole 6 is at least closed in thermally coupled 10 in the region of work surface 5, thus described hole is filled with hot linked material in this region. In other words, thermally coupled 10 simultaneously constitute for described hole closing block up. Preferably, thermally coupled is connected with the wall of motlten metal metallurgy with hole 6.
Thermally coupled 10 preferably has thickness 11 from work surface 5 to the direction of metal level 2, observes along identical direction, and described thickness is between 10% and 70% of the layer thickness 12 of other layer 3. At the two hardware 8,9 by after thermally coupled 10 connects each other in an electrically conductively, and described thermally coupled can also be called connecting element, two hardwares 8, the end of 9 is arranged at interval with work surface 5 on the one hand, and is arranged in the inside in the described region of the thickness of thermally coupled 10 on the other hand.
Thermally coupled 10 is made up of metal or metal alloy. Preferably, described thermally coupled is made up of a kind of metal or metal alloy in hardware 8,9. Nickel is especially for forming thermally coupled.
The method step of preferred method for manufacturing the sliding bearing 1 with thermocouple 7 is shown simplifiedly in Fig. 2 is to 5. At this, sliding bearing 1 is only partially shown. Additionally, described sliding bearing is shown as plane. If sliding bearing 1 be not used as plane, be used for example as thrust ring, then a layer composite deformation can also be made constituting after thermocouple 7. But because this occurs along with the load high accordingly of thermocouple 7, so the thermocouple 7 constituted in sliding bearing 1 that is molded over that layer is compound to such as half-shell is formed before.
After manufacture with preferably forming composite, described composite is constituted by metal layer on back 2 and other layer 3 or is included metal layer on back 2 and other layer 3, hole 6 processes overleaf in metal level and other layer, described hole extends through the metal composite being made up of metal layer on back 2 and other layer 3, it is to say, extend up to the work surface 5 of other layer 3 from the back side of metal layer on back 2.
Thus it is noted that sliding bearing 1 can also have multiple thermocouple 7, in order to be derived from about among work surface 5 or on the good general introduction of Temperature Distribution. For this, process the diverse location at work surface 5 for the hole 6 of each thermocouple 7, generally according to this described method manufacture described thermocouple element.
This hole 7 is preferably inserted into commercial general thermocouple 7. Thermocouple 7 has two hardwares 8,9, and described hardware is arranged in the sleeve pipe with pipe box 12 and is connected to each other by the upper end of thermally coupled 10 with described pipe box.
The interior diameter 13 in hole 7 is such as preferably 1.5mm, and described interior diameter is corresponding to the overall diameter 14 of the pipe box 12 of thermocouple 7, thus namely pipe box 12 coordinates exactly in hole 6 and abut in the wall in hole 6.
Thermocouple 7 so far inserts in hole 6, to such an extent as to thermally coupled 10 is positioned at the top of work surface 5.
Then, thermally coupled 10 originally part corresponding with the pipe box 12 of thermocouple 7 is removed together, is such as cut out, and remaining thermocouple part is drawn back into again, thus the end of hardware 8,9 is arranged in the lower section of work surface 5 as shown in Figure 3 with spacing 15. About spacing 15 size can adopt the aforesaid design of the thickness 11 (Fig. 1) for thermally coupled 10.
Instead it is also possible that the part of the thermally coupled of thermocouple element 7 and pipe box 12 is removed in inserting hole 6.
Then, particularly directly then, applying coating 16 on the work surface 5 of other layer 3 as shown in Figure 4. At this, the region in the coating 16 at least hole 6 on work surface 5 is preferably applied on whole work surface 5.
In order to form coating 16, it is preferred to use metal or metal alloy, two hardwares 8,9 are made up of described metal or metal alloy. Especially with nickel. Coating 16 can such as be cast itself.
As shown in Figure 4, the material of coating 16 pours into equally in hole 6 during being coated with and closes described hole. Therefore, it is simultaneously achieved the new hot compound 10 manufacturing two hardwares 8,9, thus thermocouple 7 again can normal operation.
The part of the coating 16 being arranged on work surface 5 then, be particularly directly again removed followed by boring work surface 5, thus retained hot compound 10 with only remaining by coating 16. This figure 5 illustrates.
For polish, it is also possible to subtly inside boring work surface 5, i.e. bearing. Work surface 5 can also arrange additional layer, such as break-in coating after coating 6 removing if desired.
However it is also possible that, in sliding bearing 1, there is the layer of more than two, the common layer of the processed traverse in hole 6, and then manufacture thermocouple 7 with described form, thus thermally coupled 10 being constructed on work surface 5.
Implement modification according to another of described method to cancel and coating 16 being removed. So this especially may be the case that, is namely coated with another layer in coating 16, and coating 16, i.e. such as nickel dam can serve as diffusion impervious layer or be used as to increase attached layer.
Although preferred enforcement the in described method uses commercial general thermocouple 7, particularly so-called sheath thermocouple in modification, but there is this probability, namely in order to construct thermocouple 7 only can by two hardwares 8,9 insert in described holes 6, and then manufacture hot compound 10 excision coating 16 times as described. But cold junction and the wiring etc. of two hardwares 8,9 must also be manufactured in this case.
Another enforcement modification according to described method can be arranged, hole 6 is with than the overall diameter 14 of thermocouple 7 or two hardwares 8, the interior diameter 13 that the width of 9 is big manufactures, thus namely constructing free space, i.e. free volume between the inwall in hole 6 and thermocouple 7 or hardware 8,9. Therefore, this free volume can manufactured by coating 16 before or after hot compound 10 at least in part with the material being thermally isolated, such as Al2O3Fill. Particularly conceive at least in part at this, namely on the layer thickness of free volume metal level 2 overleaf and/or other layer 3 remaining layer thickness (=other layer 3 layer thickness deduct hot compound 10 thickness 11) on be provided with the material being thermally isolated.
In addition to the foregoing benefits, the present invention also has the advantage that, although thermocouple 7 is arranged in other layer 3, work surface 5 is configured to continuous print. Additionally, by being completely sealed off described hole 6 by thermally coupled 10 in the region of work surface 5, the internal structure of thermocouple 7 is protected against the impact of lubricant better, and described lubricant is generally used in sliding bearing 1. But additionally, thermocouple 7 exists direct contact by thermally coupled 7 with other layer 3, wherein, fill described hole 6 based on coating 16, the region of work surface 5 exists large-area contact position.
Due to arrange be finally pointed out that, in order to understand the structure of sliding bearing 1 preferably, its component partly not to scale and/or expand ground and/or illustrate with reducing.
