Embodiment
The utility model embodiment discloses a kind of rolling bearing, with the operational situation of Real-Time Monitoring bearing.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the structural representation of the rolling bearing that Fig. 1 provides for the utility model embodiment.
In a kind of embodiment, the rolling bearing that the utility model provides comprises bearing inner race 1, bearing outer ring 2, rolling element 3, sensor 5, pulse ring 6 and magnet 7.Wherein, bearing inner race 1, bearing outer ring 2 and rolling element 3 is the basic structure of rolling bearing in prior art.Such as common deep groove ball bearing, be made up of 2, one, outer ring inner ring, 1, one group of steel ball 3 and one group of retainer 4, steel ball is enclosed within retainer, and adjacent steel ball 3 is linked together by retainer 4, and is placed between bearing inner race 1 and bearing outer ring 2.Usual bearing outer ring 2 is installed in bearing saddle bore, does not generally rotate, and bearing inner race 1 is installed on axle journal, rotates with axle.
Pulse ring 6 is fixedly connected with bearing inner race 1, rotates with bearing inner race 1 simultaneously.Pulse ring 6 is ferromagnetic substance and its outer wall offers groove.The width of groove can be arranged according to specific needs, obtains changes of magnetic field information to enable sensor.The number of groove can be one, and pulse ring 6 rotates a circle with bearing inner race 1, and groove location through magnet 7 once, causes Primary field to change.The number of certain groove also can be set to multiple, to rotate a circle the rotation situation causing the number of times of changes of magnetic field to judge pulse ring 6 with bearing inner race 1 according to pulse ring 6.The rotating speed of pulse ring 6 and bearing inner race 1 can be sensed with this sensor, and the number of turns etc. of rotating.
Magnet 7 is arranged between pulse ring 6 and sensor 5, and magnet 7 is fixedly connected with sensor 5.When above-mentioned pulse ring 6 is rotated, cutting magnetic induction line causes changes of magnetic field.Concrete, the shape of magnet 7 can be annular, and sensor 5 is installed on the side of magnet 7.Certainly, magnet 7 also can be other shapes such as bar shaped.
Sensor 5 is fixedly connected with bearing outer ring 2, and sensor 5 can induction field change, and the change in each magnetic field all can make sensor 5 be triggered, thus outwardly transmission of signal.Therefore, when pulse ring 6 is rotated with bearing inner race 1, the changes of magnetic field trigger sensor 5 caused transmits, this signal can reflect the relative motion relation of pulse ring 6 and magnet 7, again because magnet 7 is fixedly connected with sensor 5, and sensor 5 is fixedly connected with bearing outer ring 2, and pulse ring 5 is fixedly connected with bearing inner race 1 simultaneously, thus pulse ring 6 and the relative motion relation of magnet 7 also just reflect the relative motion relation of bearing inner race 1 and bearing outer ring 2, i.e. bearing operation situation.Usually, sensor 5 is connected to cable (not shown), the cable of shielding is attached on sensor 5 with circumferencial direction, and not by tension force, and cable takes up space hardly.Common, the sensor 5 can be Hall transducer, and certainly, other can other sensors of induction field change.
Some further improvement can be carried out to the rolling bearing in above-mentioned a kind of embodiment.
For the ease of installing, making the reasons such as bearing neat appearance, above-mentioned rolling bearing can arrange retaining ring inner ring 8 and retaining ring outer ring 9 further.Retaining ring inner ring 8 is fixedly connected with bearing inner race 1, and retaining ring outer ring 9 is fixedly connected with bearing outer ring 2.Pulse ring 6 is fixedly connected with retaining ring inner ring 8, and sensor 5 is fixedly connected with retaining ring outer ring 9.When bearing inner race 1 rotates relative to bearing outer ring 2, retaining ring inner ring 8 drives pulse ring 6 to relatively rotate relative to the sensor 5 be fixedly connected with retaining ring outer ring 9, magnet 7 is fixedly connected with sensor 5 again, pulse ring 6 rotates relative to magnet 7, and cutting magnetic induction line causes changes of magnetic field.
Polluted for effectively preventing rolling bearing, and prevent the lubricating grease in bearing excessive, and then the effective lubricity keeping bearing, can by sensor 5, pulse ring 6, magnet 7, the Sensor section that retaining ring inner ring 8 and retaining ring outer ring 9 form and bearing inner race 1, the bearing part that bearing outer ring 2 and rolling element 3 form adopts the mode of sealing to be connected, namely retaining ring outer ring 9 and bearing outer ring 2 are tightly connected, retaining ring inner ring 8 and bearing inner race 1 are tightly connected, pulse ring 6 and retaining ring inner ring 8 are tightly connected, sensor 5 and retaining ring outer ring 9 are tightly connected, pulse ring 6 and sensor 5 are tightly connected, common adopted clearance seal.Wherein, specifically between pulse ring 6 and sensor 5 labyrinth sealing can be adopted, namely several ring packing teeth be arranged in order are set in pulse ring 6 and the surface of contact of sensor 5, form a series of throttle clearance and expansion cavity between tooth and tooth, sealed medium produces throttle effect when the gap by tortuous labyrinth and reaches the object of Drain Resistance.Certainly, the mode that is tightly connected of other routines.
The number of sensor 5, generally can arrange one, can realize monitoring the enforcement of bearing operation situation.Certainly, the number of sensor 5 also can be set to two, is arranged at its two ends along the arbitrary radial direction of pulse ring 6.It is pointed out that the position of sensor 5 is arranged not limit to, only need to detect that pulse ring 6 rotates the changes of magnetic field caused.And in order to improve the confidence level of detection, the number of sensor 5 can be set to multiple, but a usual sensor 5 can meet Real-Time Monitoring demand.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
