Embodiment
The present invention be directed to the improvement that the maintenance of self-aligning roller bearing is carried out, general principle is：If the inner ring of bearing or
Person outer ring exist it is a certain degree of misalign or eccentric, be to be adapted to this by the spherical rotation between roller and raceway
Deflection, a certain degree of relative rotation can now occur between Internal and external cycle, this rotation is spherical rotation, belongs to normal aligning
Motion, now the deflection size of bearing internal external circle is necessarily symmetrical along a certain diametric(al) of bearing；If bearing internal external circle occurs
The deflection of non-aligning, then the deflection size of this Internal and external cycle will not will now be produced during bearing operation along a certain diameter symmetry
Abnormal motion, bearing is caused damage.According to principles above, using the special detection tool in the present invention, wind-powered electricity generation master can detect
The Internal and external cycle amount of deflection of axle self-aligning roller bearing, while bearing internal external circle can be evaluated whether there occurs the deflection of non-aligning.Specifically
Special detection tool and detection method it is as follows：
Referring to the drawings shown in 1 and 2, the special detection tool that the present embodiment is used for self-aligning roller bearing deflection detection is to include
The detection ruler of flat side 1 and inclined side 2, the flat side 1 and inclined side 2 are oppositely arranged the wedge to form the detection instrument
Shape section 3, the detection instrument end relative with the end of wedge-shaped segment 3 are squared ends 4.
And the inclined side 2 is provided with scale, the numerical value of the scale represents the thickness of the wedge-shaped segment 3, to use
In by reading scale value can measure the amount of deflection of the width in gap, i.e. bearing internal external circle, the processing of the detection instrument needs to press
It is processed according to special measuring tool standard.
Above-mentioned special detection tool is the Internal and external cycle amount of deflection for being exclusively used in detecting wind power principal axis self-aligning roller bearing, specifically
Detection method is：Referring to the drawings shown in 3, the outer seal ring for the self-aligning roller bearing of wind power principal axis 9 of dismantling, outer seal ring is arranged on
Between bearing block 5 and inner seal ring 7, dismantled in figure.The flat side 1 of the special detection tool 10 is flattened on outside the bearing
The side of circle 6, when bearing internal external circle is not deflected, bearing is not axially moved, the inner seal ring 7 of bearing is above axle
Inner ring 8 is held, when detection instrument 10 is flattened on the exposed surface of bearing outer ring 6, the lower end of detection instrument 10 just withstands on interior close
The end face of seal ring 7, now scale reading is 0, and when Internal and external cycle is there occurs during deflection, the tapered end can of detection instrument 10 stretches into
In the gap staggered to inner seal ring 7 and bearing outer ring 6, the quarter on the detection instrument 10 of the edge of inner seal ring 7 is now read
Degree, the as relative deflection motion of Internal and external cycle, the scale value are subtracted the end-play value of the self-aligning roller bearing, produce the aligning
The Internal and external cycle amount of deflection of roller bearing.
Utilize the detection method, it is possible to achieve wind power principal axis self-aligning roller bearing is examined with the presence or absence of abnormal deflection
Survey, specific detection method comprises the following steps：
(1) multigroup test position is set along the circumferential direction of the self-aligning roller bearing of the wind power principal axis, and be numbered；Its
In every group of test position be two symmetric positions centered on the axle center of the self-aligning roller bearing；
(2) respectively at the numbered positions in the step (1), using above-mentioned special detection tool to the self-aligning roller bearing
Internal and external cycle amount of deflection be measured, method is same as above, and records the reading of the special detection tool at correspondence position numbering；
(3) by the numbering corresponding with minimum value of numbered positions corresponding to maximum in the reading result of record in step (2)
Position line, if the line, by the axle center of the self-aligning roller bearing, and its monosymmetric position is compiled centered on the line
Reading value at number is equal, then shows that the self-aligning roller bearing belongs to aligning deflection, show that the bearing is without exception；If the line is not
By the axle center of the self-aligning roller bearing, and the not phase of the reading value centered on the line at its monosymmetric Position Number
Deng then showing that the self-aligning roller bearing belongs to the deflection of non-aligning, show that the bearing has abnormal motion, remind maintainer to need
Prevention bearing exception stress is taken steps to fail.
Also, the detection method also includes：By the way that the line compared with the shaft core position of the self-aligning roller bearing, is judged
The self-aligning roller bearing produces the direction deflected extremely.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, this
Art personnel make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, all fall within this hair
In bright protection domain.
