Description

Dynamic High-accuracy bearing end-play measuring instrument

Technical field:

The utility model relates to bearing measuring instrument technical field, a kind of Dynamic High-accuracy bearing end-play measuring instrument that is used for non-separation miniature bearing.

Background technology:

At its end-play measuring instrument of the known finished product bearing of bearing industry, generally all be by the outer ring fastener, the inner ring charger of loading up and down, and formation such as torsion spring table pointer, according to JJG66-89<ball bearing end-play measuring instrument vertification regulation〉requirement, carry out the bearing end-play and measure, the shortcoming that this known method exists is as follows:

1, in order to guarantee that the bottom platen loading surface is under the original upload situation, contact fully with the lower surface of measured bearing inner ring, ball-and-socket and bulb aligning device have been adopted, though this device has guaranteed contact contact fully then, but because the depth of parallelism between outer ring locating device and the loading surface exists bigger error, thereby make under the situation that load loads down, inner ring and outer ring exist certain deflection, it is that rigidity contacts that last load is presented a theatrical performance as the last item on a programme with the last surface of contact of inner ring, upper holder when last load loads and inner ring upper surface initially are to contact, load fully later on because of the aligning device of loading down, just make inner ring that certain deflection has been arranged, thereby just contact fully with upper holder, the deflection of inner ring all is at random under this situation, inner ring is in the effect of load up and down, when doing the displacement of two extreme positions, if gauge head is not strictly to touch the inner ring center, the displacement that records, then inevitably increased the influence factor that random quantity that inner ring tilts etc. can not be predicted, and because the restriction of structure, gauge head can only pass through bascule, following load guide rod, the indirect measurement mechanism of one cover such as core-regulating mechanism and bottom platen acts on the bearing inner race center, under the influence of this covering device composition error, gauge head not only can not act on the center of inner ring, and can not guarantee that gauge head is on the same point of bearing inner race when measuring, from and increased the uncertain factor of a measured value, because above-mentioned these inevitable defect, the measured value determinacy that this method is drawn is poor, poor repeatability has influenced measuring accuracy greatly.

2, the measured bearing inner ring is under the effect of loading up and down, need reach the high-low limit position of relative outer ring raceway, could guarantee that measured value leans on, but because interfere the existence of error between bearing channel and the retainer, can not make all roller body arrive desirable extreme position cmpletely, in order to improve this situation, cover manual setters such as rotary handle have been increased in the existing product, shake by handle, make rolling body arrive desirable extreme position as far as possible, but can't eliminate the influence of interfering error to be brought so fully.

3, known apparatus measures is static spot measurement, mostly is three point measurements generally speaking most, if carry out the more measurement of multiple spot for the reliability of proof test value, survey will be through repeatedly again loading adjustment, just can finish, waste time and energy, and the poor repeatability of measured value.

4, the display mode of known instrument measured value is that the torsion spring table shows, the calculating of the definite and play value of upper and lower sides value except that the error of torsion spring itself, has added bigger artificial subjective error fully by manually finishing inevitably.
