In order to achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of rolling bearing structure of embedded wheel speed sensors, including connected by outer ring 1, roller 2, retainer 3 and inner ring 4
The rolling bearing of composition, rolling bearing are embedded with wheel speed sensors, and wheel speed sensors acquire retainer transient speed information and carry out
Rolling bearing fault diagnosis.
The wheel speed sensors are the magneto-electric type wheel speed sensor or Hall-type wheel speed that sensor main body 5 and gear ring are constituted
Sensor.
When using magneto-electric type wheel speed sensor, fixed sensor main body 5 on outer ring 1, retainer 3 is equipped with gear ring, tooth
Circle tooth coca is designed according to the working range that wheel speed sensors are popped one's head in, the distance between sensor main body 5 and gear ring after making installation
In normal range of operation in magneto-electric type wheel speed sensor.
The sensor main body 5 is fixed on outer ring 1 by 1 built-in hole of outer ring, or is mounted on outer ring 1 by bracket 6
On.
Gear ring teeth directional on the retainer 3 is made into axially or radially.
The sensor main body 5 includes shell 5-1, is equipped with permanent magnetic core 5-3 inside shell 5-1, outside permanent magnetic core 5-3
Equipped with induction coil 5-2, induction coil 5-2 is connected with electronic circuit 5-4.
When using Hall wheel speed sensor, retainer 3 is made into toroidal magnet form, by gear ring design in inner ring 4 or
Person outer ring 1, sensor main body 5 design on retainer 3.
Speed probe in the rolling bearing structure combination shaft of the embedded wheel speed sensors, can be used in rolling
The calculating of bearing slip.
The invention has the benefit that
Since in rolling bearing operational process, reflected transient speed signals include failure abundant on retainer
Information, and transmitting between failure excitation and transient speed signals and transformation Relative Vibration signal are simply more, therefore, instantaneous turn
Fast signal Relative Vibration signal is more sensitive to failure, and signal-to-noise ratio is higher.
Wheel speed sensors and rolling bearing design are structure as a whole, easy to use, at low cost.

Specific embodiment
The present invention is described in more detail with embodiment with reference to the accompanying drawing.
Embodiment 1, as shown in Figure 1-Figure 3, a kind of rolling bearing structure of embedded wheel speed sensors, including outer ring 1, roller
2, the rolling bearing that retainer 3 and inner ring 4 connect and compose, in 1 built-in hole of outer ring on fixed sensor main body 5 and retainer 3
Gear ring constitute magneto-electric type wheel speed sensor, the measurement method of non-cpntact measurement do not influence the normal work of rolling bearing；By magnetic
The gear ring and retainer 3 of electric-type wheel speed sensors are made of one, the work model that wherein gear ring tooth coca is popped one's head according to wheel speed sensors
Design is enclosed, the distance between sensor main body 5 and gear ring after making installation are in the normal work model of magneto-electric type wheel speed sensor
In enclosing, when local fault occurs for the components such as outer ring 1, roller 2, retainer 3, inner ring 4, the collected holding of sensor main body 5
The transient speed signals of frame 3, transient speed signals include fault signature, can be used for the fault diagnosis of rolling bearing.
The sensor main body 5 includes shell 5-1, is equipped with permanent magnetic core 5-3 inside shell 5-1, outside permanent magnetic core 5-3
Equipped with induction coil 5-2, induction coil 5-2 is connected with electronic circuit 5-4.
Embodiment 2, the fixed form of the sensor main body 5, position are not limited to the embodiment form shown in 1, due to
5 main function of sensor main body is the transient speed for measuring retainer 3, as long as non-rotatable member, sensor can be fixed in
Gear ring on alignment probe retainer 3, for example sensor main body 5 is fixed on outer ring 1 by way of bracket 6, such as scheme
Shown in 4- Fig. 6 structure.
Gear ring teeth directional on the retainer 3 can be made radial direction, as shown in Figure 1-Figure 3, may be alternatively configured axial direction, such as scheme
Shown in 4- Fig. 6.
Magneto-electric type wheel speed sensor working principle: when the shaft rotation connecting with inner ring 4, retainer 3 is with its feature frequency
Rate is rotated, and the gear ring of side constantly cuts the magnetic line of force of permanent magnetic core 5-3, generates electric signal, can be by acquiring the telecommunications
Number realize rolling bearing fault diagnosis.Hall wheel speed sensor working principle is similar with magneto-electric type wheel speed sensor, passes through
The variation of magnetic field strength is converted to electric signal by Hall element, electronic circuit.For magneto-electric type wheel speed sensor, using electromagnetism
Induction realizes the wireless transmission function of sensing device self-powered and signal in conjunction with electronic circuit.
If retainer 3 is made into toroidal magnet form, sensor main body 5 is placed using Hall wheel speed sensor
In non-rotatable member, what wheel speed sensors were surveyed is the telecommunications generated when gear ring relative sensors main body 5 moves by electromagnetic induction
Number, as long as gear ring and sensor main body 5 have relative motion to generate electric signal, so designing gear ring in inner ring 4 or outer ring
1, the design of sensor main body 5 also can be realized measurement function on retainer 3.
The present invention is suitable for embed the rolling bearing structure of wheel speed sensors, and the failure of bearing is carried out based on the structure
Diagnostic work.It should be pointed out that being based on above-mentioned design principle, and similar fault diagnosis work is carried out, even if public in institute of the invention
That makes in the structure basis opened is some without substantive changes or polishing, used structure design and diagnosis thinking still with
The present invention is the same, therefore it should also be as within the scope of the present invention.
