On be machined with the first supporting part and the second supporting part, its outer circumference surface is arcwall face.The inner peripheral surface of outer rim ring segment test specimen 10b is
Lower surface, its outer circumference surface is upper surface, the upper surface of pressure head 2 and outer rim ring segment test specimen 10b, and with installing hole to be measured 5
It is correspondingly arranged, outer rim ring segment test specimen 10b can be pressed.Load charger when in use, outer rim ring segment test specimen 10b by its
One supporting part and the second supporting part are sticked in the first cylinder 8 and the second cylinder 9 forms simple beam structure, and pressure head component is close
The upper surface of outer rim ring segment test specimen 10b and when pressing to it, i.e. pair with installing hole to be measured 5 vertically corresponding position presses when, outward
Edge ring segment test specimen 10b bends, and makes to produce circumferential stress at the outer rim of installing hole to be measured 5.
Load loading method provided in an embodiment of the present invention comprises the steps：
S10, to intercept and include one section of ring body of installing hole to be measured to obtain ring segment test specimen, peace to be measured on pitch variable bearings outer ring
Centre position of the dress hole position on the ring segment test specimen circumferencial direction, in other words, two truncation surfaces of installing hole to be measured and ring segment
Apart from roughly equal.In an alternative embodiment, the ring segment for including installing hole on pitch variable bearings inner ring can also be intercepted as examination
Part.
S20, processes the first supporting part on the outer circumference surface of ring segment test specimen and the second supporting part obtains inner edge ring segment test specimen
10a, specifically includes procedure below.
The part outer circumferential sides material of ring segment test specimen is removed, and the first supporting part and the second supporting part is processed in the side,
Both at parallel to installing hole to be measured and through the elongated slot of ring segment test specimen, the cross sectional shape of elongated slot is semi arch or minor arc.And
And, the first supporting part and the second supporting part are symmetrical with regard to symmetrical plane, and the symmetrical plane is through installation axially bored line to be measured and becomes oar
Bearing outer ring center line.And the material between installing hole to be measured and datum plane is removed, makes installing hole to be measured be changed into elongated slot.
S30, there is provided the first bearing and the second bearing, by the first bearing and the second bearing inner edge ring segment test specimen is supported respectively
The two ends of 10a, that is, support inner edge ring segment test specimen 10a the first supporting part and the second supporting part, now inner edge ring segment test specimen 10a with
Two bearings constitute simple beam structure.With reference to Fig. 2, Fig. 2 shows the composition of the simply supported beam.First bearing and in the present embodiment
Two bearings are cylindric supporter, and by the periphery of cylindric supporter first supporting part of inner edge ring segment test specimen 10a is embedded in
With the elongated slot of the second supporting part, the stable support to inner edge ring segment test specimen 10a is formed.
S40, to inner edge ring segment test specimen 10a alternation test load is applied, and tests direction and first bearing and second of load
The bearing pressure that bearing is provided is in opposite direction, and the application point of the test load is located at installation axially bored line to be measured and inner edge ring segment test specimen
In the coplanar plane of 10a axis.Specifically, the step can be performed on tensile and compression testing machine, can pass through the pressure head shown in Fig. 2
Component applies alternate load to inner edge ring segment test specimen 10a, and pressure head component acts on the inner peripheral surface of inner edge ring segment test specimen 10a.Treat
Surveying the inner edge of installing hole can be subject to circumferential alternate stress, the alternate stress to make fatigue failure at inner edge, realize to pitch variable bearings
The measure of outer ring installing hole inner edge fatigue strength.
By said method, intercept containing installing hole one section of ring body on pitch variable bearings outer ring and be simulated load as test specimen
Lotus loading test, without the need for carrying out clamping and loaded load test to whole pitch variable bearings outer ring, can adopt such as tensile and compression testing machine
Common apparatus is tested, and the requirement to test equipment is relatively low.Further, since the material of installing hole outer rim to be measured is eliminated, it is right
Inner edge ring segment test specimen 10a applies less load can be made to produce enough strains at the inner edge of installing hole to be measured, it is possible to decrease right

One supporting part and the second supporting part are symmetrical with regard to symmetrical plane, and the symmetrical plane is outside installation axially bored line to be measured and pitch variable bearings
Circle center line, and the material between installing hole to be measured and datum plane is removed, make installing hole to be measured form elongated slot.
First supporting part and the second supporting part of two seat supports outer rim ring segment test specimen 10b can be passed through, so as to by outside
Edge ring segment test specimen 10b is also configured as simple beam structure, can be made by the outer circumference surface imposed load to outer rim ring segment test specimen 10b
Circumferential stress is produced at the outer rim of installing hole to be measured, the measure to pitch variable bearings outer ring installing hole outer rim fatigue strength is realized.
In one alternate embodiment, process the first supporting part and during the second supporting part, not to installing hole to be measured with it is cylindrical
Material between side face or inner peripheral surface is removed process.That is, the inner edge of installing hole to be measured and outer rim on ring segment test specimen is retained
Solid material.Ring segment test specimen with complete inner edge and outer rim, when load loading is tested, its stressing conditions is closer actual,
Test result is more accurate.
In one alternate embodiment, the first supporting part and the second supporting part can not be processed on ring segment test specimen, directly
The support of the first bearing and the second bearing is received as supporting part using its inner peripheral surface or outer circumference surface, the first bearing and second
Seat carries out adaptability deformation, and with ring segment test specimen simple beam structure is formed.
In another embodiment, load loading method also includes step S50：At the inner edge of installing hole to be measured or outer rim
Strain transducer is set, the detection signal of strain transducer is collected when test load is applied to ring segment test specimen.Passed by straining
Sensor can collect circumferential strain value at ring segment test specimen inner edge and/or outer rim, it can be determined that at radial load and inner edge and/or outer rim
Strain stress relation.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, various equivalent modifications can be readily occurred in or replaced
