CN203422075U - Device for measuring radial runout of industrial long rotating shaft - Google Patents

Abstract

The utility model discloses a device for measuring the radial runout of an industrial long rotating shaft. The device comprises a lantern ring. The vertical cross section of an inner annulus wall of the lantern ring is arc-shaped, and the inner annulus wall is provided with a ring-shaped groove. A sensor array formed by a plurality of pressure-sensitive sensors is arranged inside the ring-shaped groove. A ball is rotatably mounted in the notch of the groove at a position corresponding to each pressure-sensitive sensor, being in contact with the corresponding pressure-sensitive sensor. By using the device provided by the utility model, the radial runout of the rotating shaft can be conveniently measured with a relatively high measuring precision.

Description

The long rotating shaft radial pulsation measurement of a kind of industry device

Technical field

The utility model relates to rotating shaft measurement mechanism field, is specially the long rotating shaft radial pulsation measurement of a kind of industry device.

Background technology

in machinery industry, radial stability when some workplace countershaft is worked requires very high, and when particularly shaft length is longer, the degree of its diameter run-out is corresponding increase also.In prior art, countershaft radial pulsation measurement is comparatively difficult, cannot meet machinery industry requirement.

Utility model content

The purpose of this utility model is to provide the long rotating shaft radial pulsation measurement of a kind of industry device, the problem existing to solve prior art.

In order to achieve the above object, the technical scheme that the utility model adopts is:

The long rotating shaft radial pulsation measurement of a kind of industry device, include the collar, it is characterized in that: minimum in the middle of the internal ring wall vertical cross-section of the described collar is shaped to, curved cambered surface is gone up respectively in both sides, and in internal ring wall, having vertical cross-section is also the annular groove of identical cambered surface, in annular groove, be provided with the sensor array that a plurality of voltage sensitive sensors form, and in each sensor array, each voltage sensitive sensor is arranged along described cambered surface respectively, corresponding each voltage sensitive sensor position, groove notch place is rotatablely equipped with respectively ball, described ball contacts with corresponding voltage sensitive sensor.

The described long rotating shaft radial pulsation measurement of a kind of industry device, it is characterized in that: described collar outer wall is fixed with box body, in box body, be provided with single-chip microcomputer, signal acquisition circuit and wireless module, described signal acquisition circuit and wireless module access respectively single-chip microcomputer, and each sensor array is connected with signal acquisition circuit by signal wire respectively.

In the utility model, rotating shaft is rotatably installed in the collar, if there is diameter run-out in rotating shaft, can make ball compress corresponding voltage sensitive sensor array by extruding ball, thereby generation electric signal, by a plurality of voltage sensitive sensor array conjunction measurings, can measure easily rotating shaft diameter run-out, and there is good measuring accuracy.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.
