Abstract
The utility model discloses a kind of combination sensor structures for magnetic suspension bearing, including rotor and displacement sensor, the end of the rotor is equipped with boss portion, the inner face of boss portion is cone structure, even number displacement sensor is evenly arranged on the circumferencial direction of rotor, and displacement sensor is located at the side of the conical surface in boss portion.The utility model eliminates radial displacement transducer, keeps structure simple, saves space；Rotor axial size shortens, and improves the intrinsic frequency of rotor.
Description
Technical field:
The utility model relates to a kind of combination sensor structures for magnetic suspension bearing.
Background technique:
The radial direction of rotor 1 and axial change in displacement need to use two kinds of sensors (as schemed in existing magnetic suspension bearing
2), in 4 radial displacement transducers of the circumference uniform distribution of rotor 1, to detect the radial position of rotor.It is installed in 1 one end of rotor
One shaft position sensor, to detect the axial position of rotor.Using two sensors, the axial peace of rotor 1 can be made
Dress space becomes larger, and increases rotor axial length.
Utility model content:
The utility model is provided a kind of for magnetic suspension bearing to solve the above-mentioned problems of the prior art
Combination sensor structure.
Technical solution used by the utility model has: a kind of combination sensor structure for magnetic suspension bearing, including
Rotor and displacement sensor, the end of the rotor are equipped with boss portion, and the inner face of boss portion is cone structure, even number displacement
Sensor is evenly arranged on the circumferencial direction of rotor, and displacement sensor is located at the side of the conical surface in boss portion.
Further, the angle between the conical surface and rotor axis in the boss portion is 30 ° -45 °.
Further, institute's displacement sensors are equipped with 2 or 4.
The utility model has the following beneficial effects:
1, radial displacement transducer is eliminated, keeps structure simple, saves space；
2, rotor axial size shortens, and improves the intrinsic frequency of rotor.
Detailed description of the invention:
Fig. 1 is the utility model structure chart.
Fig. 2 is the layout drawing of this peritrochanteric radial displacement transducer and shaft position sensor in the prior art.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1, a kind of combination sensor structure for magnetic suspension bearing of the utility model, including rotor 1 and displacement are passed
Sensor 3, the end of rotor 1 are equipped with boss portion 11, and the inner face of boss portion 11 is cone structure, and even number displacement sensor 3 is equal
Cloth is on the circumferencial direction of rotor 1, and displacement sensor 3 is located at the side of the conical surface in boss portion 11.
Angle between 1 axis of the conical surface in boss portion 11 and rotor is 30 ° -45 °.
Displacement sensor 3 is equipped with 2 or 4.
The utility model eliminates original radial displacement transducer, 2 or 4 axial sensors of circumference uniform distribution, rotor
Detection faces be made into the conical surface, the differential detectable radial displacement in 180 ° of directions of sensor, the size of sensor detected value summation can be with
Detect axial displacement.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The protection scope of the utility model.
