Abstract
The utility model discloses a shaft rotating speed measurement sensor. The sensor comprises a supporting disk, on which an outer supporting ring is fixed. An inner supporting ring is installed at the center of the outer supporting ring. A plurality of inner contact points made of pressure-sensitive material are arranged in the inner wall of the outer supporting ring. Each inner contact point is connected to a wire. An outer contact point is arranged on the outer wall of the inner supporting ring. A plurality of embedding grooves are provided in the inner wall of the inner supporting ring. An installation ring, on the outer wall of which a plurality of embed seats are provided, is arranged inside the inner supporting ring. The sensor, which is high in sensitivity and precision, can satisfy the measurement requirements of mechanical equipment shaft rotating speed.
Description
Technical field
The utility model relates to sensor field, is specially a kind of axle rotating speed measuring sensor.
Background technology
The rotary speed parameter of axle construction is performance parameter important in a lot of plant equipment, in actual production, need to measure plant equipment axle construction rotating speed, to obtain accurately rotary speed parameter.The sensitivity of prior art axle construction rotation-speed measuring device, precision are relatively poor, can't satisfy measurement demand.
The utility model content
The purpose of this utility model provides a kind of axle rotating speed measuring sensor, to solve the problem of prior art axle construction tachometric survey sensitivity, low precision.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of axle rotating speed measuring sensor, include supporting disk, it is characterized in that: be fixed with the outer support ring on the supporting disk, outer support ring center rotating is equipped with the inside support ring that is total to central shaft with the outer support ring, and in, has the gap between the outer support ring, be provided with on the described outer support ring inwall a plurality of along circumferential ring around interior contact that the pressure sensitive of inside support ring is made, be connected to respectively the wire that passes from the outer support ring on the contact in each, be provided with the outer contact that can contact with the extruding of interior contact on the inside support ring outer wall, described inside support ring inwall is provided with a plurality of caulking grooves in inside support ring, the interior also gapless altogether central shaft of described inside support ring is provided with installing ring, and described installing ring outer wall is provided with a plurality of embedded seats that can embed one by one in the caulking groove.
Described a kind of axle rotating speed measuring sensor is characterized in that: described inside and outside support ring axial length equates that the axial length of described installing ring is longer than inside support ring, and installing ring is longer than on the ring wall section of inside support ring and is provided with a plurality of connecting thread through holes.
Described a kind of axle rotating speed measuring sensor is characterized in that: described outer support ring outer wall is provided with a pair of Connection Block, and described outer support ring is fixed on the supporting disk by Connection Block.
When the utility model uses, axle and installing ring are fixed, connecting thread through hole and axle that fixed form can adopt bolt to be screwed into installing ring are fixed, when axle rotates, drive installing ring, inside support ring rotates jointly, the outer contact on the inside support ring when rotating with the outer support ring in the contact contact, thereby make the stressed crimp in interior contact, produce electric signal, after electric signal is sent to external signal collection and treatment facility and processes by wire, can obtain the rotary speed data of axle construction.
The utlity model has higher sensitivity and precision, can satisfy plant equipment middle shaft structure tachometric survey demand.
