Abstract
A kind of capacity eccentric bearing eccentricity measurement tooling, includes fixing device, measuring device.The fixing device is made of the dial framework and bearing being fixed on the base, and by the shaft being connect with bearing, the amesdial on dial framework is matched with the capacity eccentric bearing to be measured being connected in shaft to be combined into the measuring device.Its is simple in structure, is only made of several parts, and part is easy to manufacture, also low manufacture cost, simple operation, only needs to measure maximum, minimum two numerical value, therefore measurement is quick, measurement efficiency is high.When designed shaft has taper with bearing fit to be measured, capacity eccentric bearing self-locking can be made to fix, and be measured suitable for the eccentricity of all capacity eccentric bearings, while also expand the measurement number of degrees of amesdial twice, reduced number of degrees error, make eccentricity X=（The minimax number of degrees）/ 2, therefore high certainty of measurement.
Description
Technical field
The present invention relates to a kind of measurement tooling, especially a kind of capacity eccentric bearing eccentricity measures tooling.
Background technology
With the development of S＆T tax, the purposes of bearing is more extensive, can more especially meet specific use and with not
Congenerous, airframe bearing kind continue to bring out, for ensure bearing quality, reach the function and effect with bearing auxiliary products
Fruit need to test the main performance index project of bearing.
Existing measurement of the bearing industry to capacity eccentric bearing eccentricity, generally uses three-coordinates measuring machine, this measuring instrument not only at
This high measurement speed is slow, goes back machine benzene and is not easy to move again, cannot meet bearing industry high speed development demand.
The power that number of patent application CN201611238246.8 " a kind of capacity eccentric bearing " is provided is a kind of structure of capacity eccentric bearing.
The patent No. 201620798367.7 " a kind of oil-free vortex air compressor machine capacity eccentric bearing axial position regulating mechanism ", it is main
To be used for adjusting the axial fit clearance between the associated Moving plate of bearing and price fixing, quickly adjust bearing axial position, improve life
Produce efficiency.
Invention content
The technical problem to be solved by the present invention is to：A kind of capacity eccentric bearing eccentricity measurement tooling is provided, it is simple in structure, easy
It makes, low manufacture cost, and simple operation, high certainty of measurement, efficient, the particularly suitable bias small to eccentricity error requirements
The measurement of bearing eccentricity.
Technical solution is used by the present invention solves the above problems：Capacity eccentric bearing eccentricity measures tooling, includes solid
Determine device, measuring device, the fixing device is made of the dial framework and bearing being fixed on the base, the measuring device by with axis
The shaft for holding connection, the amesdial on dial framework is matched with the capacity eccentric bearing to be measured being connected in shaft to be combined into.
Compared with the prior art, the advantages of the present invention are as follows：Capacity eccentric bearing eccentricity measures tooling, simple in structure, only
It is made of several parts, and part also low manufacture cost easy to manufacture, simple operation, original is difficult the eccentricity measured, now only needs to survey
Maximum, minimum two numerical value of amount just solve, therefore measure fast, and measurement efficiency is high.Designed shaft have taper with it is to be measured
When bearing fit, capacity eccentric bearing self-locking can be made to fix, and be measured suitable for the eccentricity of all capacity eccentric bearings, while also by thousand points
The survey measurements of table expands twice, reduces error in reading, make eccentricity=（Maximum-minimum number of degrees）/ 2, therefore measurement accuracy
It is high.
Description of the drawings
The structural schematic diagram of Fig. 1, the present invention（Stereogram）.
Fig. 2, design schematic diagram of the present invention.
Specific implementation mode
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
Fixing bearing 3 on the eccentric position of 4 side of pedestal, bearing outer ring fixation will not rotate.
Shaft 2, the up-small and down-big taper for having 5-15 degree, the upper end of shaft 2 and the inner ring of capacity eccentric bearing 1 to be measured position, and
Capacity eccentric bearing 1 to be measured can be retained automatically, while the bearing for being suitable for different inner ring sizes again uses, the lower end of shaft 2 is inserted into
In the inner ring of 4 upper bearing (metal) 3 of pedestal, with the rotation of shaft 2,3 inner ring of bearing rotates together.
Dial framework 6 is made of the entirety connected into through straight, horizontal screw 8,7 with cross, the straight-bar 61 of clear opening, crosspiece 62, and
The straight-bar 61 with vertical through hole is locked by horizontal screw 7, by straight screw 8 by the cross with cross through hole and gap adjustment slot 63
Shelves 62 are locked.
Dial framework 6 is fixed on by 61 lower end of straight-bar thereon on an edge of pedestal 4.
The gauge outfit bar 51 of amesdial 5 is inserted through cross through hole on crosspiece 62 and gap adjustment slot 63 and bias to be measured
Bearing 1 coordinates, with straight, horizontal screw 8,7 can upper and lower, front and back adjusting amesdial to suitable position.
Fixing device is made of the dial framework 6 and bearing 3 being fixed on pedestal 4, and measuring device is by the shaft that is connect with bearing 3
2, the amesdial 5 on dial framework 6 is matched with the capacity eccentric bearing to be measured 1 being connected in shaft 2 to be combined into.
In use, capacity eccentric bearing 1 to be measured is placed on the top of shaft 2, amesdial 5 is opened, eccentric shaft to be measured is rotated with hand
1 is held, is minimum when it turns to amesdial reading, in location A, amesdial is zeroed, rotates eccentric shaft to be measured with hand again
It is maximum value to hold 1 and go to amesdial reading, and in B location, obtained value is twice of surveyed capacity eccentric bearing eccentricity, is led to
Cross the eccentricity for calculating and can directly obtaining bearing 1 to be measured.
To ensure that O1, O2 bias are in the same horizontal line in Fig. 2 after rotation, the radius R of bearing 1 to be measured, eccentricity X,
To the long and short edge of capacity eccentric bearing, maximum, minimum range is a and b to eccentric position.
A+b=2R a=2R-b=2（x+b）- b=2x+b x=a-b/2 are eccentricity.
x+b=R。
