Specific embodiment

The core of the utility model is to provide a kind of vibration monitoring device for bogie axle axle box bearing, the vibration monitoring Device meet to the Vibration Condition of axle box bearing carry out in real time, effectively, steadily monitor on the basis of, simplify erector Sequence.

In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and specific implementation The utility model is described in further detail for mode.

Fig. 1 to Fig. 3 is please referred to, Fig. 1 is the load distribution schematic diagram of axle box bearing in specific embodiment；Fig. 2 is a left side of Fig. 1 View；Fig. 3 is the vibration detection component of vibration monitoring device and the installation schematic diagram of axle box in specific embodiment.

The embodiment provide vibration monitoring device be used for monitor bogie axle box bearing 100 vibration signal, with for The accident analysis of subsequent axle box bearing 100 provides data.

Wheel pair is installed, the both ends for the axle 400 taken turns pair pass through axle box bearing 100 on the bogie of rail vehicle, wherein Axle box bearing 100 is installed in axle box 200, connects the inner surface of axle box 200 and the periphery of axle box bearing 100 Touching；Axle box 200 and wheel are on the framework for being mounted on bogie.

The vibration monitoring device that the embodiment provides includes vibration detection component, which is installed on axle box 200, and it is corresponding with the bearing area 100a of axle box bearing 100；That is, the vibration detection component is on axle box 200 Installation site correspond to axle box bearing 100 bearing area 100a.

Discovery is researched and analysed by inventor, when axle box bearing 100 is there are when local fault damage, in the effect of load Under, local fault damage can generate impact, which shows as vibrating, in this way, vibration detection component is installed on axis There is part inside axle box bearing 100 in place corresponding with the bearing area position 100a of axle box bearing 100 on cabinet 200 When failure is damaged, due to the effect by load on the 100a of bearing area, local fault damage can be with axle box bearing 100 Rotation and generate periodic impact because axle box bearing 100 is contacted with axle box 200, which can be transmitted to Place corresponding with the bearing area position 100a of axle box bearing 100 on axle box 200, to be installed in the vibration of the position Detection part detection.

As it can be seen that the vibration monitoring device can carry out the Vibration Condition of axle box bearing 100 in real time, effectively and stably to supervise It surveys, meanwhile, vibration detection component need to be only installed on axle box 200, without in axle box 200 and axle box bearing 100 Between additional mounting structure is set, simplify installation procedure, also can reduce the stress rupture to axle box 200.

In specific scheme, vibration detection component selects vibrating sensor 300, and structure is simple, easy for installation.

As shown in Figure 1, vehicle is in the process of running, axle box 200 mainly by the top-down vertical load of car body, from And compress axle box bearing 100, that is to say, that under the action of vertical load, axle box 200 is fitted closely with axle box bearing 100； Fr indicates radial force in Fig. 1, and Fa indicates cross force.

Axle box bearing 100 other than bearing above-mentioned vertical load, generates in the process of running also subject to from rail wheeling action Longitudinally, laterally, vertical force, wherein above-mentioned vertical load be Main Load, comprehensive analysis, in actual moving process, axle box The bearing area 100a of bearing 100 is mainly the region leaning on close over and contacting with axle box 200.

Here top on the basis of the relative positional relationship of each component to define, Ke Yili under vehicle normal operating condition Solution, far from wheel track direction be it is upper, close to wheel track direction be under.

Specifically, the bearing area 100a of axle box bearing 100 is 0 degree of position one of deviation above axle box bearing 100 The position of side predetermined angle to deviate 0 degree position other side predetermined angle position between fan ring region, wherein define across The position intersected above the vertical lines at 100 center of axle box bearing and axle box bearing 100, the 0 ° of position as marked in Fig. 2.

With reference to Fig. 2, the above-mentioned vertical lines across 100 center of axle box bearing are Y-axis marked in figure, pass through axis in figure The lateral straight line at 100 center of axle box bearing is X-axis, wherein the point being located above that Y-axis intersects with axle box bearing 100 is as aforementioned 0 degree of position of definition.

With reference to Fig. 2, the position for deviateing predetermined angle on the left of 0 degree of position is A point, deviates predetermined angle on the right side of 0 degree of position Position is B point, and A point is the bearing area 100a of axle box bearing 100 to the fan ring region between B point.

In specific scheme, the range of above-mentioned predetermined angle is 45 °~65 °, that is to say, that between A point and 0 degree of position Angle is 45 °~65 °, and the angle between B point and 0 degree of position is 45 °~65 °.

In practice, the specific range of bearing area 100a can be determined according to Experimental Calibration or analogue simulation etc..

Vibrating sensor 300 is installed on the position that above-mentioned bearing area 100a is corresponded on axle box 200.In practice, It can be according to the specific installation site because usually determining vibrating sensor 300 such as actual installation space.

With reference to Fig. 3, in illustrated scheme, vibrating sensor 300 is specifically installed on 0 degree of position for deviateing axle box bearing 100 The position that 50 °~55 ° of right side avoids interfering with car body associated components to avoid 200 top position of axle box.Certainly, vibration passes Sensor 300 is also mountable to deviate the position in the left side of 0 degree of position of axle box bearing 100.

Specifically, vibrating sensor 300 is installed on 55 ° of position for deviateing 0 degree of position of axle box bearing 100, the position In the 100a of bearing area, 100 fault-signal of axle box bearing can be accurately and effectively collected, which is not necessarily to existing There is axle body structure to be changed, can directly apply, in addition, the installation site facilitate the installation of vibrating sensor 300 with Maintenance.

Certainly, when actual setting, vibrating sensor 300 is also mountable to other places corresponding with bearing area 100a, It is not limited to as shown in the figure.

Above-mentioned left and right is to be located in figure with components in Fig. 2 and Fig. 3 and the definition of positional relationship that components are mutual , it is intended merely to the clear and scheme of statement technical solution, the protection scope of the application should not be limited.

In specific scheme, vibrating sensor 300 is detachably connected by fastener with axle box 200.

Specifically, threaded hole 201 is offered on axle box 200, vibrating sensor 300 passes through bolt and axle box 200 Installation.

More specifically, the extending direction of threaded hole 201 is the radial direction of axle box bearing 100, in order in the work of load Under, impact caused by local fault is damaged is transferred to vibrating sensor 300 well.

Detailed Jie has been carried out to the vibration monitoring device provided by the utility model for bogie axle axle box bearing above It continues.Specific case used herein is expounded the principles of the present invention and embodiment, and above embodiments are said The bright method and its core concept for being merely used to help understand the utility model.It should be pointed out that for the common of the art For technical staff, without departing from the principle of this utility model, can also to the utility model carry out it is several improvement and Modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
