Specific embodiment
As illustrated, a kind of contact force distribution detecting device of rolling bearing roller, including camera 7, base 1, it is located at
The guide plate 2 and loading contact 3 of the top of base 1, loading contact 3 are connected with load bringing device, wherein, the upper surface of base 1
On be provided with the lock chamber 101 for accommodating roller 4 to be detected, the both sides of lock chamber 101 are provided with support 102, and guide plate 2 is fixed on
On the support 102 and top in lock chamber 101, is provided with the slot 201 of its thickness direction of insertion, in slot on guide plate 2
201 have been inserted into testing piece 5, and the lower end for testing piece 5 contacts with the surface of roller to be detected 4 in lock chamber 101, and upper end is fixed on
One bottom of loading blocks 6, the top of loading blocks 6 contacts with loading contact 3, so that the loading force of loading contact 3 is by adding
Carry block 6 and test piece 5 be applied on the face of cylinder bus of roller to be detected 4, the camera 7 is arranged on the side of test piece 5,
Deflection for shooting test piece 5.
