Embodiment 1

[0020] like figure 1 As shown, a built-in speed measurement device for a supercharger includes a speed sensor 1, a bearing body 2, and a speed sensor 3 is a rotating shaft. The speed sensor 1 is provided with a speed sensor center 4, and the speed sensor 1 is connected to the bearing body 2. A positioning plane 6 is set at the position, and the bearing body 2 is closely positioned through the positioning plane 6, and a detection platform 5 is set on the rotational speed test piece 3 (such as figure 2 ), the detection platform 5 is set on two symmetrical planes on both sides of the rotating shaft, the speed sensor 1 and the bearing body 2 are connected by M10 X 1 fine thread, and suspended at a certain distance above the speed tested part 3, And face the detection platform 5 on the rotational speed tested part 3, the measurement gap L between the rotational speed sensor center 4 on the rotational speed sensor 1 and the detection platform 5 is 0.5-1.2 mm.

Embodiment 2

[0022] like image 3 As shown, a turbocharger built-in speed measurement device includes a speed sensor 1, a bearing body 2, a positioning plane 6 is provided at the connection between the speed sensor 1 and the bearing body 2, and the speed measured part 3 includes a shaft cover 7 and a rotating shaft 8. The shaft cover 7 is tightly fitted on the rotating shaft 8. The shaft cover 7 is sandwiched between the compressor impeller 10 and the bearing sleeve 11, and the axial clamping force ensures its firm positioning and connection. The detection platform 5 is two symmetrical The boss plane 9 (as Figure 4 ), set on the shaft cover 7, the speed sensor 1 is provided with a speed sensor center 4, the speed sensor 3 is provided with a detection platform 5, the speed sensor 1 and the bearing body 2 are connected by a fine thread of M12 X 1.25, And it is closely positioned by the positioning plane 6; and it is suspended at a certain distance above the speed tested part 3, and is faci...

Abstract

The invention relates to a built-in rotation speed measurement device of a supercharger. The device comprises a rotation speed sensor (1), a bearing body (2) and a piece (3) with the rotation speed to be measured, wherein the rotation speed sensor (1) is provided with a rotation speed sensor center (4), the piece (3) with the rotation speed to be measured is provided with a measurement platform (5), and the rotation speed sensor (1) is connected with the bearing body (2) through fine threads and suspended at a position a certain distance above the piece (3) with the rotation speed to be measured and right faces the measurement platform (5) on the piece (3) with the rotation speed to be measured to form a measurement gap L. Because the rotation speed sensor is firmly fastened to the bearing body of the supercharger, the device is simpler in structure, and accordingly it is guaranteed that the sensor can be reliably used for a long time.

Description

technical field [0001] The invention belongs to the field of a speed measuring device of a turbocharger, and in particular relates to a built-in speed measuring device of a turbocharger. Background technique [0002] As the operating speed and pressure ratio of the turbocharger become higher and higher, the structure of the compressor and turbine of the turbocharger becomes more complicated, and many problems appear. Reliable and effective measurement of turbocharger speed has become one of the outstanding problems. The greater the error of the turbocharger speed measurement, the lower the effectiveness of the turbocharger bench performance test, and the turbocharger overspeed in the matching test of the turbocharger and the engine is ignored. [0003] In order to accurately measure the speed of the supercharger, various measures and methods have been taken. For example, a bakelite stick sensor is installed at the air inlet of the compressor, and the speed of the supercha...
