Description
Technical field
The utility model relates to a kind of bearing detecting devices more particularly to a kind of tapered roller bearing incipient fault detection to fill
It sets.
Background technique
At present in rotating machinery, rolling bearing is crucial one of component of machine, if bearing oil is not using
When or environmental condition it is harsh, will lead to bearing earlier period damage, have many bearing iron filings pieces and generate, at this time if continued to use
The bearing of abnormal failure may result in the structural failure around shaft and axle box etc., the iron filings piece that furthermore faulty bearings generate
If into geared parts, the risk for the secondary hazards that gear part can be caused to damage.
The real-time detection system for state of installation bearing, but most of monitoring system prices are required in every field at present
Valuableness, installation is inconvenient, and based on the significant data mainly by acquiring bearing, Lai Jinhang analyses whether that bearing exists
Failure, when the vibration of bearing and entire mechanical device and noise mix, it is difficult to detect that the iron filings piece of bearing is fallen.
Detect that the iron filings piece of bearing early stage is particularly important in time.
Summary of the invention
Bearing iron filings piece and possibility are generated in order to detect that abnormal damage occurs in the early stage of bearing described in background technique in time
The phenomenon that causing secondary hazards, the utility model provide a kind of tapered roller bearing incipient fault detection device, when bearing occurs
When the iron filings piece of early stage, part iron filings sector-meeting is outflowed with lubricating oil from bearing inner race big end, since filter grid can stop iron filings
The outflow of piece rotates with inner ring in sensor proximity and generates floating state, can be adsorbed to sensor over time
On, when sensor detects iron filings piece, i.e. there is initial failure in discovery bearing, while also avoiding bearing iron filings piece and fly out to make
The phenomenon that at secondary hazards.
Technical solution used by the utility model include: by connecting plate I(1), filter grid (2), seal cover board (3),
Connecting plate II(4), magnetic-type iron powder sensor (5), wiring (6) composition, it is characterised in that connecting plate I(1) and connecting plate II(4) use
In connection seal cover board (3) and bearing outer ring (7), connecting plate I(1) and connecting plate II(4) one end is at equal intervals by washer and nut
It is fixed on seal cover board (3), one end is fixed on bearing outer ring (7)；Filter grid (2) is welded on seal cover board (3)；Magnetic
Formula iron powder sensor (5) is fixed on filter grid (2) by washer and nut;Wiring (6) on magnetic-type iron powder sensor (5)
By being pierced by filter grid (2).Seal cover board (3) inner ring is placed in tapered roller bearing internal ring (8) big end, seal cover board
(3) outer ring and tapered roller bearing outer ring (7) parallel alignment.Lubricating oil flows to bearing inner race (8) greatly from bearing inner race (8) small end
End is flowed out from filter grid (2), and the iron filings piece that bearing damage is fallen is blocked in filter grid (2) and swims in bearing inner race
(8) it near big end, is finally attracted on magnetic-type iron powder sensor (5).
The utility model having the beneficial effect that compared with the background art.
(1) the utility model structure is simple, is easily installed, and can go out the abnormal phenomenon of bearing in early detection in time.
(2) when there is the iron filings piece of bearing, it can stop to fly out in time, damage the two of surrounding components and gear
Secondary harm.
(3) the utility model is expected to be suitable for various uses, harsh environment especially big in vibrations such as engineering machinery
Middle use.
Detailed description of the invention
Attached drawing 1 is the overall structure diagram of the utility model.
Attached drawing 2 is the separated structure schematic diagram of the utility model and tapered roller bearing.
Attached drawing 3 is the mounting structure schematic diagram of the utility model and tapered roller bearing.
Specific embodiment
The present invention is further described with example is applied with reference to the accompanying drawing.
As shown in Fig. 1, connecting plate I(1), filter grid (2), seal cover board (3), connecting plate II(4), magnetic-type iron powder pass
Sensor (5), wiring (6).
As shown in Fig. 2, connecting plate I(1), filter grid (2), seal cover board (3), connecting plate II(4), magnetic-type iron powder pass
Sensor (5), bearing outer ring (7), bearing inner race (8), rolls body support frame (9), rolling element (10) at wiring (6).
Connecting plate I(1) and connecting plate II(4) for connecting seal cover board (3) and bearing outer ring (7), connecting plate I(1) and
Connecting plate II(4) one end is fixed on seal cover board (3) by washer and nut at equal intervals, and one end is fixed on bearing outer ring (7)；
Filter grid (2) is welded on seal cover board (3)；Magnetic-type iron powder sensor (5) is fixed on filter grid (2) by washer and nut
On;Wiring (6) on magnetic-type iron powder sensor (5) in filter grid (2) by being pierced by.Seal cover board (3) inner ring is placed in circular cone
In roller bearing inner ring (8) big end, seal cover board (3) outer ring and tapered roller bearing outer ring (7) parallel alignment.
Working principle of the present invention is as follows.
When the iron filings piece of early stage occurs in bearing, part iron filings sector-meeting flows to axis from bearing inner race (8) small end with lubricating oil
It holds inner ring (8) big end to flow out from filter grid (2), the iron filings piece that bearing damage is fallen is blocked in filter grid (2) and floats
Trip is finally attracted on magnetic-type iron powder sensor (5) over time near bearing inner race (8) big end.Work as magnetic-type
When iron powder sensor (5) detects iron filings piece, i.e. there is initial failure in discovery bearing, while also avoiding bearing iron filings piece and flying out
Cause the secondary hazards phenomenon to peripheral component and gear.
