TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts processing, and particularly relates to a lubricating mechanism for a supercharger intermediate body. BACKGROUND

[0002] The turbine intermediate body is used for driving the turbine to work by gas, and the turbine drives the air compressor to rotate at high speed, thereby increasing the density of the entering gas and improving the power of the engine.

[0003] The intermediate body in the existing turbine intermediate body is injected with oil through an oil port arranged on the body of the intermediate body and an oil delivery pipeline, but the structure is complex, the position of the oil delivery pipeline 3 needs to be accurately set during the manufacturing process, and the manufacturing process is very complicated.

[0004] Patent No. CN201220750143.0 discloses an intermediate body and a supercharger, wherein the oil port of the intermediate body in the prior art is converted into a direct communication between the oil inlet and the lubricating oil cavity by using the oil delivery pipeline to communicate with the lubricating shaft cavity, compared with the prior art, the oil delivery pipeline is reduced, the positions of the oil inlet and the lubricating oil can be better determined during the manufacturing process, the manufacturing difficulty is reduced, and the manufacturing time of the intermediate body is shortened.

[0005] However, the oil delivery pipeline from the oil inlet to the inner cavity of the rotating shaft has only one oil delivery pipeline, and the lubricating oil needs to overflow from the lubricating oil cavity to flow into the first turbine shaft cavity and the second turbine shaft cavity, and if the oil delivery pipeline is blocked, it is not easy to clean up because the oil delivery pipeline is designed in one body with the shell. CONTENT

[0006] The utility model discloses a lubricating mechanism for supercharger intermediate body, which can directly pass lubricating oil cavity and turbine shaft cavity on both sides, and is convenient to disassemble and clean up.

[0007] Preferably, the mounting hole is arranged at four corners of the valve body and penetrates up and down.

[0008] Preferably, the depth of the conical hole is 1 / 2 of the height of the valve body.

[0009] Preferably, the shunt holes on both sides of the conical hole include an inclined pipe at the upper part and a straight pipe at the lower part, and the shunt hole at the bottom of the conical hole is a straight pipe.

[0010] Preferably, the included angle between the inclined pipe and the straight pipe is 135°.

[0011] Preferably, the oil inlet protrudes from the upper surface of the valve body or is embedded in the upper surface of the valve body.

[0012] Preferably, the three diversion orifices have the same diameter.

[0013] This utility model designs the integrated turbocharger intermediate body housing as a split type. By pre-diverting the lubricating oil in the lubrication mechanism, and then through the straight pipe of the diversion pipe, it is respectively connected to the lubricating oil chamber and the turbine shaft chambers on both sides through three branch pipes, so that the lubricating oil temperature in contact with the shafts at the three locations is consistent. Moreover, due to the split design, it is more convenient to disassemble, clean, replace and maintain. Attached Figure Description
