Amount, and lubricating oil is transferred heat to, the temperature of lubricating oil becomes higher to form deep fat.
As Figure 1-Figure 4, fuel feed hole 101 and oil-feed tank 100, fuel feed hole 101 and oil inlet can be equipped on body part 10
Slot 100 connects, and oil-feed tank 100 is connected with gap 3, and lubricating oil can be flowed into from outside by fuel feed hole 101 in oil-feed tank 100,
Lubricating oil in oil-feed tank 100 can flow into gap 3 and carry out heat exchange with the deep fat in gap 3, and the deep fat in gap 3 also may be used
To flow into oil-feed tank 100 and flow back to gap 3 again after carrying out heat exchange with the lubricating oil in oil-feed tank 100, in short, from fuel feed hole
The 101 new lubricating oil (abbreviation fresh oil) flowed into can carry out heat exchange with the deep fat in gap 3, the fresh oil after heat exchange and heat
The miscella of oil further can carry out heat exchange with rotation axis 2, so as to reduce the temperature of rotation axis 2, improve rotation
The working performance of axis 2.
As Figure 1-Figure 4, oil outlet 111 can be equipped on body part 10 and go out oil groove 110, oil outlet 111 with it is fuel-displaced
Slot 110 connects, and goes out oil groove 110 and is connected with gap 3, and the major function for going out oil groove 110 is collection and discharge deep fat.Deep fat can be from
Gap 3 is flowed into out in oil groove 110, then flows out bearing shell 1 by oil outlet 111 from oil groove 110 is gone out.In addition, rotation axis 2 and bearing shell 1
Between impurity can also flow to out oil groove 110, rotation axis 2 rotates at a high speed in bearing shell 1, if there are impurity, meetings in gap 3
Frictionally damage is formed on rotation axis 2 to influence the performance of rotation axis 2, by setting out oil groove 110, impurity can with deep fat or
It is that rotation axis 2 flows to out oil groove 110, so as to improve the performance of bearing shell 1.
Bearing shell 1 according to embodiments of the present invention, by setting oil-feed tank 100 and going out oil groove 110, oil-feed tank 100 and fuel-displaced
Slot 110 is spaced apart, so as to realize 1 oil inlet of bearing shell and fuel-displaced relative independentability so that is flowed into from oil-feed tank 100 new
Oil can be sufficiently mixed with the deep fat in gap 3, and fresh oil can carry out sufficient heat exchange with deep fat, so as to effectively
Reduce the temperature of rotation axis 2.In addition, the deep fat and impurity around rotation axis 2 can be flowed out from oil groove 110 is gone out, oil groove 110 was gone out both
Fuel feeding Xun Huan can be cooperatively formed with oil-feed tank 100, fully to cool down to rotation axis 2, can also be improved clear in bearing shell 1
Cleanliness, and then the lubricant effect between bearing shell 1 and rotation axis 2 can be improved.
According to some embodiments of the present invention, in the rotation direction of rotation axis 2, oil-feed tank 100 is located at oil groove 110
Downstream.For example, as shown in Fig. 2, the rotation direction of rotation axis 2 is counterclockwise, oil-feed tank 100 is located at a left side for oil groove 110
Side (left side as shown in Figure 2).The deep fat at gap 3 may collect in out at oil groove 110 and be flowed out from oil outlet 111 as a result, from
And space can be provided for the infeed of fresh oil so that fresh oil can fully cool down to rotation axis 2, improve fresh oil and rotation axis 2
Indirect heat exchange efficiency, so as to improve the working performance of bearing shell 1.Further, oil-feed tank 100 close to go out oil groove 110.By
This, can extend the action path of fresh oil and deep fat and effect duration, so as to improve fresh oil and deep fat effect.
As shown in Figure 1-Figure 3, according to some embodiments of the present invention, oil-feed tank 100 can be along body with going out oil groove 110
The circumferential direction distribution in portion 10.In other words, oil-feed tank 100 can be located on same annulus with going out oil groove 110.Thus, it is possible to just
In oil-feed tank 100 and go out being extended in 2 axial direction of rotation axis of oil groove 110, fresh oil and deep fat effect can be improved.
