In diametric(al) plus gauge block that one piece is less than rib width, measured workpiece reclines gauge block；
Step 3: amesdial is placed on the magnetic force dial framework 1 being arranged on platform, table point is put into rib and survey edge,
Read indicating value of the amesdial in A points；
Step 4: the gauge block being placed on by measured workpiece is taken away, it is straight along the maximum of measured workpiece with hand propelled measured workpiece
Footpath direction is come on the baffle plate of sine protractor, reads indicating value of the amesdial in B points；
Step 5: the indicating value that B points are subtracted with the indicating value of A points is when removing gauge block, what amesdial table point was declined hangs down
Straight height H, and table point is from A points to the end face and the baffle plate of sine protractor that the horizontal range L of B points is the measured workpiece contacted with gauge block
Between horizontal range, and then obtain negative dorsal horn α=tan of rib-1(H/L)。
The invention has the advantages that：The invention provides a kind of unique direct measurement low-angle cylinder roller bearing
The method that the narrow rib of inner ring bears dorsal horn, the method is accurate, easy, quick, is easy to promote, and measurement rib is less than 2mm, and angle is less than
It is 1 ' 13 that 1 ° of bearing ring, which bears dorsal horn uncertainty, ", it disclosure satisfy that measurement demand of the measurement tolerance ± 5 '.

Embodiment
Embodiment one：With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4 explanation, the quick measurement bearing of one kind of present embodiment
The method that the narrow rib of inner ring bears dorsal horn comprises the following steps：Step 1: burr and dust on cleaning measured workpiece 3 surface,
Measured workpiece 3 is put on platform 6 and adapts to environment temperature, waits to be measured；
Step 2: sine protractor 4 is placed on platform 6, then measured workpiece 3 is kept flat on sine protractor 4, in measured workpiece 3
Maximum gauge direction on plus one piece of gauge block 5 for being less than rib width, measured workpiece 3 reclines gauge block 5；
Step 3: amesdial 2 is placed on the magnetic force dial framework 1 being arranged on platform 6, table point is put into rib and survey side
Edge, reads indicating value of the amesdial 2 in A points；
Step 4: take away the gauge block 5 for being placed on the side of measured workpiece 3, with hand propelled measured workpiece 3 along measured workpiece 3 most
Major diameter direction is come on the baffle plate of sine protractor 4, reads indicating value of the amesdial 2 in B points；
Step 5: the indicating value that B points are subtracted with the indicating value of A points is when removing gauge block 5, the table of amesdial 2 point is declined
Vertical height H, and table point is from A points to the end face that the horizontal range L of B points is the measured workpiece 3 contacted with gauge block and sine protractor 4
Baffle plate between horizontal range, and then obtain negative dorsal horn α=tan of rib-1(H/L)。
