Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown, this hub-bearing unit sealing ring contact condition observation device, mainly includes sealing ring, graduated scale
2, connector sleeve 3, pedestal 4, bracket 6, location nut 7 and fixture nut 8, bracket 6 and 3 sets of connector sleeve on the axle journal of pedestal (4),
Location nut 7 and fixture nut 8 are connected on the axle journal of pedestal 4, bracket 6 is between location nut 7 and fixture nut 8, branch
Frame 6 is fixed in location nut 7, carries out upper-lower height adjusting by location nut 7, and fastened with fixture nut 8.Bracket 6 with
Connector sleeve 3 is connected and fixed, and is fixedly connected between bracket 6 and connector sleeve 3 by connecting bolt 5.Sealing ring is located in connector sleeve 3
Side, and the cooperation that is in contact with pedestal 4, sealing ring and connector sleeve 3 are interference fitted.It is connected in the base step 12 of 4 bottom of pedestal
One through-hole is arranged at graduated scale 2,4 bottom of pedestal, is cooperated with graduated scale 2 by bolts and nuts and is fixed, and graduated scale 2 is for measuring connection
Cover the gap at bottom and base step.Keep bracket 6 and pedestal 4 fixed using location nut 7 and fixture nut 8, location nut 7 and quarter
Degree ruler 2 is used to adjust and measure sealing ring sealing lip and sealing contact surface matching allowance.
Some removal of 3 lateral wall of connector sleeve, removal angle is α, is matched with guaranteeing that sealing ring sealing lip is contacted with pedestal 4
Conjunction can be observed.Some is removed sealing ring by cutting machine, and removal angle is α, to guarantee sealing ring sealing lip
Contacting with pedestal 4 can be observed.Sealing ring and connector sleeve 3 are fixed by sealing ring framework and the interference fit of connector sleeve 3, mistake
The amount of being full of and practical set state consistency.The pressing sleeve 9 that fits through of sealing ring and connector sleeve 3 positions, and is existed with the load of loading mechanism 10
Sealing ring is pressed into connector sleeve 3 on pressing sleeve 9, cooperation is formed and fixes.
When sealing ring is I 1-1 of sealing ring that sealing lip flexes outward, pedestal 4 is equipped with the angle R, the angle R and I 1-1 mistake of sealing ring
It is full of cooperation.
The calculation of sealing ring sealing lip and pedestal magnitude of interference H in sealing contact are as follows: magnitude of interference H=H1- (H2+H3),
Middle H1 is sealing lip elongation, and H2 is that sealing ring is pressed depth, and H3 is connector sleeve and pedestal gap in sealing contact.Sealing lip elongation
Amount H1 is sealing ring actual value, and sealing press fitting depth H 2 is measured by altimeter, and outer ring passes through with pedestal gap H3 in sealing contact
Graduated scale measurement.
When sealing ring is II 1-2 of sealing ring that sealing lip inwardly stretches, pedestal 4 is equipped with cylinder step 11, cylinder step
11 connect cooperation with pedestal 4 with 3 clearance fit of connector sleeve, guidance connector sleeve 3, and cylinder step 11 is matched with II 1-2 interference of sealing ring
It closes.
The calculation of sealing ring sealing lip and pedestal magnitude of interference H in sealing contact are as follows: magnitude of interference H=(H1+H4)-(H5+H2
+ H3), wherein H1 is sealing lip elongation, and H2 is sealing ring compression distance, and H3 is connector sleeve and pedestal gap, and H4 is that step is high
Degree, H5 are seal chamber depth.H1 and H5 is sealing ring actual value, and H2 sealing press fitting depth is measured by altimeter, H3 connector sleeve
It is measured with pedestal gap by graduated scale, H4 step height is device design height.
This hub-bearing unit sealing ring contact condition observation method first will including observation device described above
Sealing ring is pressed into connector sleeve 3 by pressing sleeve 9 and loading mechanism 10, utilizes the depth of altimeter measurement sealing ring indentation；Then will
Location nut 7 is installed on the axle journal of pedestal 4, then bracket 6 and connector sleeve 3 is fixed by connection bolt 5, passes through connector sleeve 3
Inner hole and 12 diameter of base step guidance cooperation guidance be installed in the location nut 7 of pedestal 4, pass through adjusting location nut
The gap of 7 height adjustment connector sleeve 3 and pedestal 4, measures gap by graduated scale 2, to calculate the sealing lip of sealing ring
With the magnitude of interference of 4 sealing contact surface of pedestal；Finally by the cooperation of fixture nut 8 fixed bracket 6 and pedestal 4, locking sealing
Enclose the magnitude of interference of sealing lip and pedestal sealing contact surface, then to observing sealing ring sealing lip and the surface that is engaged under projector
It is bonded pattern and deformation extent.
Before sealing ring is installed, the sealing ring of cutting machine cutting removal α angle, cutting side are utilized to hub bearing sealing ring
To the sealing ring center of circle excessively.Then the α angle of sealing ring removal and the α theta alignment of connector sleeve are coincide, is then pressed into connector sleeve
3, such as not enough fastening, the skeleton of sealing ring and glue on point at the cooperation of connector sleeve 3, reinforce fixed rigidity.
By adjusting sealing ring sealing lip and pedestal magnitude of interference, can be obtained sealed increscence amount and sealing lip deformation extent with it is close
The corresponding relationship of sealing label conjunction state, measurement data can do the later period and research and analyse.
The present invention can restore the hub bearing sealing ring contact shape of seal lip with contact surface under practical entrucking state
State；It is observed by body formula mirror, it is actual to get rubber sealing ring lip and contact surface under the conditions of sealing ring difference magnitude of interference
Juxtaposition metamorphose degree analyzes sealing lip force and deformation state and seal lip with CAE theoretical modeling and is bonded shape with contact surface
State compares and analyzes, and provides support for the design of hub bearing sealed increscence amount.
Seal lip and sealing surfaces contact condition can directly be observed.It can flexible modulation, measurement seal lip and sealing
Surface difference magnitude of interference, obtains the corresponding relationship of different magnitude of interference Yu seal lip contact condition, to simulate and studying hub spindle
The optimal lip magnitude of interference held under sealing ring difference contact condition provides support.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
