The axle sleeve support base for supporting bearing to be tested during the test is additionally provided in bearing radial rigidity test device.
Specifically, axle sleeve support base includes reed 13, and reed 13 is arranged in the form stood up, the top side setting of reed 13
There is the axle sleeve fixing seat that bottom bracket axle is held for connecting shaft, bearing is fixed on reed 13 by axle sleeve fixing seat, in the present embodiment,
Using be located at 13 top of reed flanging 131 as axle sleeve fixing seat, flanging 131 and axle sleeve by threaded fastener connection come
It is kept fixed.The axis and 13 place plane of reed of bearing are parallel and perpendicular to 13 thickness direction of reed.Reed 13 is by water
Can be swung when square to active force, when supporting air bearing sliding bearing 10 can with the movement of support air bearing sliding bearing 10 and
Movement, using left and right directions shown in Fig. 1 as the width direction of reed 13, in the up and down direction of diagram i.e. the length side of reed 13
To then reed 13 more easily deforms in a thickness direction, the ratio between rigidity is in the width direction of reed 13, length direction
1:10, reed 13 are difficult to deform in the up-down direction, to guarantee that reed 13 supports stablizing for bearing.
It is additionally provided in the radial outside of air bearing sliding bearing 10 to bearing to be measured and the exciting device of exciting active force is provided,
Exciting device includes exciter support 25, and vibration excitor 23 is provided on exciter support 25, and 23 communication link of vibration excitor is connected to signal
Generator 21 and power amplifier 24, signal generator 21 generate pumping signal and pass to after the amplification of power amplifier 24 sharp
Shake device 23, and vibration excitor 23 is made to generate exciting active force, and vibration excitor 23 acts on vibration excitor mandril 22, and vibration excitor mandril 22 connects
There is the horizontally extending connecting rod 20 using as press end, exciting active force is directly transmitted to as axis by connecting rod 20
On the bearing outer wall 11 of set, make bearing outer wall 11 when by exciting active force with the axis offset of rotary main shaft 32 it is certain away from
From the position cooperated on bearing outer wall 11 with connecting rod 20 is planar structure.
In order to be recorded to exciting force size suffered by bearing outer wall 11 and the corresponding displacement generated, Hydrostatic last item
Holding radial rigidity test device further includes data acquisition device, and data acquisition device includes the pressure being arranged on vibration excitor mandril 22
The displacement sensor 28 and data collecting card 27 arranged with 20 opposite side of connecting rod, two sensors are arranged in force snesor 26
All be connected on data collecting card 27, data collecting card 27 directly connect with terminal computer 40 storage for having carried out paired data and
It calculates.When arranging two sensors, pressure sensor 26, the arrangement of displacement sensor 28 and 32 axis of rotary main shaft are arranged same
On one horizontal plane, to eliminate influence of the gravity to 10 stiffness measurement of air bearing sliding bearing.Specifically, displacement sensor is solid
It is scheduled on bearing outer wall 11, on the basis of rotary main shaft 32.When not loading exciting force or constant force, what displacement sensor 28 measured
Mounting distance of the data between rotary main shaft 32 and bearing outer wall 11, when loading exciting force or constant force, displacement sensor 28
The data of measurement be it is mobile after bearing outer wall 11 and rotary main shaft 32 between spacing and mounting distance absolute value.
When operator uses the hydrostatic bearing radial rigidity test device in the present invention, by bearing holder (housing, cover) to be tested
On rotary main shaft 32, and bearing to be tested and reed 13 is fixed, then gas circuit is connect with air bearing sliding bearing 10, it will be high
Body of calming the anger is passed into bearing, is made full of high pressure gas between bearing and axle journal, bearing to be detected has been completed turning round at this time
Assembly on main shaft 32, and high pressure gas has also separated rotary main shaft 32 with bearing.
Operator starts vibration excitor 23, makes the output exciting active force outward of vibration excitor 23, and connecting rod 20 pushes outside bearing
Wall 11 acts, and when moving, the air film shape being made of in bearing high pressure gas changes bearing outer wall 11, connect with bearing
Reed 13 swung after bearing outer wall 11 is by exciting active force, bearing with reed 13 swing when motion profile be arc
Line, but since 13 swinging distance of reed is very small, the motion profile that can be approximately considered bearing is along connecting rod 20
The straight line that the direction of motion extends.Two sensors correspond to the displacement collected bearing in radial directions and connecting rod 20 to unofficial biography
The exciting force size passed is transferred to terminal computer 40, according to Rigidity Calculation formula: K=F/ △ corresponds to obtain air film in bearing
The radial rigidity of rigidity i.e. air bearing sliding bearing 10, wherein F is exciting force size, and △ is the radial displacement of bearing.It needs
It should be noted that calculate at this time to rigidity further include reed 13 rigidity, therefore can be in the feelings for not being passed through high pressure gas
Condition, which gets off to calculate, obtains the rigidity of reed 13, to be exactly axis by the rigidity that the rigidity obtained by above-mentioned formula subtracts reed 13
Hold the rigidity of itself.
In addition, different radial loads can be tested to bearing radial direction by adjusting the exciting force size that vibration excitor 23 exports
The influence of rigidity；It can influence of the measuring rotating speed to bearing radial rigidity by adjusting 30 revolving speed of high-speed induction motor；Pass through replacement
High-pressure air source can measure the influence to bearing radial rigidity such as gas with various such as supercritical carbon dioxide, nitrogen, air；It is logical
The control and regulation to parameters such as gas pressure, flow, temperature are crossed, can be measured under different heat-mechanical characteristics, gas is to axis
Hold the influence of radial rigidity.In addition to that can test gas bearing, the hydrostatic bearing in the present invention is radially rigid
Degree test device can also test fluid lubricated bearing.
In other embodiments, in addition rotary main shaft, which can be, is assemblied on bearing to be tested, can be according to be measured
The size of bearing selects the rotary main shaft of correspondingly-sized.
In other embodiments, on bearing to be tested for press end cooperation position can for arcuate structure or its
His curved-surface structure, and no longer use planar structure.
In other embodiments, the arrangement form of pressure sensor and displacement sensor can correspond to replacement, such as will pressure
The same side of bearing is arranged in force snesor and displacement sensor.
In other embodiments, other forms be could alternatively be for detecting the displacement sensor of bearing displacement, such as
Being sticked on reed has foil gauge, and the displacement for obtaining bearing is corresponded to by pressure change on foil gauge.
In other embodiments, reed width direction, rigidity ratio can use 1:11, other ratios such as 1:12 on length direction
Example, is not limited to 1:10.
In other embodiments, if you do not need to higher revolving speed, then flange-face coupling, sliding block shaft coupling can be used
The low speed such as device, gear coupling replace the high speed bellows being mounted between the output shaft of motor and rotary main shaft with shaft coupling
Shaft coupling.
Since vibration excitor can not only provide exciting, it is also capable of providing constant force of different sizes, therefore in other embodiments
In, the vibration excitor constant force different to bearing output size also can be used, pass through Rigidity Calculation formula: K=F/ △ is to be measured to calculate
The rigidity of bearing.
