Specific embodiment
Gather Figure of description below and embodiment is entered to a kind of axle Dynamic Carrying Capacity experiment with measuring device of this utility model
Row is described in detail：
As shown in figure 1, a kind of axle Dynamic Carrying Capacity experiment with measuring device, including damping block 1,1 upper surface of damping block is formed
Groove, bearing 8 are placed in groove, and 1 lower surface center of damping block is provided with axis 9, and the pivot of axis 9 is placed on support shaft nest 6
In sunken end face；Force cell 3 is placed in below support shaft nest 6, is contacted with support shaft nest 6, and by lead 7 and dynamometry instrument
4 connections；2 upper end of axle is installed on below rotor 5, and lower end surface forms friction pair with bearing 8.
The force cell 3 is from SF series off-standard voltage output LOAD CELLSs.
The dynamometry instrument 4 selects the general sensing data processing instrument of DM2405 types.
The force cell 3 is placed in below the support shaft nest 6 of damping block 1, can measure axis by force cell 3
Pressure of 9 pivot to support shaft nest 6, you can obtain the Dynamic Carrying Capacity of axle 2.Due to block size dampened, installation site and
The restriction of peripheral electromagnetic field, 3 desired size of force cell is little, sensitivity of weighing, measurement are stable, operating temperature range width, does not receive
The features such as supply frequency and magnetic field affect.Force cell 3 is from SF series off-standard voltage output LOAD CELLSs, the sensing
Device constitutes high-performance using high stable, high-performance thick film strain element and ceramic diplopore spring beam and weighs sensory system, and measurement is steady
It is fixed, operating temperature range width, and do not affected by supply frequency, magnetic field etc..Measurement range is 0～20N, and certainty of measurement is
0.05%, test measurement required precision can be met.By lead 7 is drawn in force cell 3, it is connected with dynamometry instrument 4, by surveying
Power instrument 4 shows the numerical value of Dynamic Carrying Capacity, and this value is the Dynamic Carrying Capacity of axle.
The dynamometry instrument 4 selects the general sensing data processing instrument of DM2405 types.
Measuring principle of the present utility model：
2 upper end of axle is arranged on below rotor 5, and lower end surface constitutes friction pair, 2 institute of equipment running process axis with bearing 8
The Dynamic Carrying Capacity for bearing derives from 5 weight of rotor, by measurement axis 2 to the pressure of bearing 8 realizing countershaft Dynamic Carrying Capacity
Measurement.Bearing 8 is arranged on damping block 1, and the pressure of the axle suffered by bearing 8 can be converted into 1 axis of damping block, 9 pivot to propping up
The pressure of axle nest 6 is held, the Dynamic Carrying Capacity of axle is just obtained by measuring 9 pivot of axis to the pressure of support shaft nest 6.
Using method of the present utility model：
Before damping block 1 is assembled, 4 reading of record dynamometry instrument, as the table truth of a matter.Load damping block 1, axle 2 is inserted and is turned
Below son 5, tested on Dynamic Carrying Capacity assay device, 4 reading of dynamometry instrument was recorded per 30 seconds, until raising speed is arrived
Running speed, realizes the real-time measurement to 2 Dynamic Carrying Capacity of axle in operating condition.
