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
The invention belongs to the rotation-speed measuring device field of turbosupercharger, be specifically related to the built-in rotation-speed measuring device of a kind of supercharger.
Background technology
Along with working speed and the pressure ratio of turbosupercharger are more and more higher, the pneumatic plant of supercharger and the structure of turbine are more complicated, and show great number of issues.The measurement of reliable and effective supercharger speed becomes one of distinct issues.The error that supercharger speed is measured is larger, and the validity of supercharger Bench Experimental Study is lower, and supercharger hypervelocity when supercharger and Engine Matching test is left in the basket.
People, for Measurement accuracy supercharger speed, have taked many kinds of measures and method.For example at compressor inlet end, bakelite bar type sensor is installed, is shown supercharger speed on digital instrument, measuring accuracy is rotating speed 1.5%.Or sensor is arranged in to compressor impeller radial direction, shows rotating speed by frequency spectrograph.Or the spindle nose in supercharger rotating shaft is arranged the methods such as magnetic nut.
Long-term use or the limitation such as measuring accuracy is low installed, is not suitable for to above-mentioned measuring method because of inconvenience, and under special needs, it is unactual that the application of above-mentioned technology becomes.
Summary of the invention
Technical matters to be solved by this invention is exactly inconvenience to be installed, to be not suitable for long-term use or the circumscribed problem such as measuring accuracy is low for existing measurement mechanism, provides a kind of supercharger built-in rotation-speed measuring device.
The present invention solves the problems of the technologies described above the technical scheme of employing:
The built-in rotation-speed measuring device of a kind of supercharger, comprise speed probe 1, bearing body 2, rotating speed measured piece 3, on speed probe 1, be provided with speed probe center 4, on rotating speed measured piece 3, be provided with detection platform 5, speed probe 1 is connected by fine thread with bearing body 2, and be suspended at rotating speed measured piece 3 a distance, top, and just right with the detection platform 5 on rotating speed measured piece 3, form measurement clearance L.
Further, on speed probe 1, be provided with plane of orientation 6 with bearing body 2 junctions, rotating speed measured piece 3 is rotating shafts, detection platform 5 is two symmetrical planes, be arranged on the both sides of described rotating shaft, speed probe 1 is connected by M10 X 1 fine thread with bearing body 2, and is adjacent to location by plane of orientation 6, and the measurement clearance L between speed probe center 4 and detection platform 5 on speed probe 1 is 0.5～1.2mm.
Further, on speed probe 1, be provided with plane of orientation 6 with bearing body 2 junctions, rotating speed measured piece 3 comprises shaft seal cover 7 and rotating shaft 8, shaft seal cover 7 is tightly placed in rotating shaft 8, detection platform 5 is two symmetrical boss planes 9, be arranged on shaft seal cover 7, speed probe 1 is connected by the fine thread of M12 X 1.25 with bearing body 2, and being adjacent to location by plane of orientation 6, the measurement clearance L between the boss plane 9 on speed probe center 4 and shaft seal cover 7 on speed probe 1 is 0.5～1.2mm.
The present invention compared with prior art its beneficial effect is:
(1) because speed probe is firmly fastened on supercharger bearing body, structurally simpler, so guaranteed sensor long term reliability;
(2) because rotating speed measured piece is placed in supercharger inside, dustless no-sundries, so guarantee the long term reliability of measured piece;
(3) because rotating speed measured piece need not be magnetic, need only given configuration structure, so contribute to keep the accuracy of tachometric survey;
Because of speed probe and fixed form simple and reliable, so reduced the cost that changes the outfit.
