There has been proposed previously by the present applicant (Japanese Unexamined Patent Publication No.
229515). As shown in FIG. 6, such a measuring device includes an outer race 2 of a tapered roller bearing 2 on a case end wall side cover 1A of a transmission 1.
A base 3 having a spacer portion 3A in contact with A is set via a rod 4, and a load is applied to the base 3 by a hydraulic cylinder 5 while rotating a main shaft 1B of the transmission 1. Then, while changing the load, the base 3 and the case end wall side cover 1A at that time are changed.
The gap displacement from the end face and the applied load are measured, and regression analysis is performed based on the measured data to obtain a regression equation. Based on this regression equation, the gap amount when the load is 0 is calculated. Then, as shown in FIG.
When the thickness of A is A, the end play is C, and the shim thickness to be obtained is D, the shim thickness D is calculated by calculating D = ABC.

わらない。However, in such a conventional shim thickness measuring device, the outer wall of the outer race 2A of the tapered roller bearing 2 and the inner wall of the case end wall side cover 1A are measured in an interference fit state. ing. For this reason, when a load is applied to the base 3, a frictional force exists between the outer wall of the outer race 2A of the tapered roller bearing 2 and the inner wall of the case end wall cover 1A, and the frictional force is applied to the bearing roller 2B and the inner race 2C. The load is not transmitted 100%.

If the load to be transmitted to the inner race side is F1 and the frictional force is F2, then F0 = F1 + F2, and F0 ≠ F1.

ある。Therefore, a load lower than the actual load acts on the inner race 2C due to the frictional force F2, and the measured data becomes lower than the true data. Further, the load is changed and the respective amounts of change are plotted. However, since the frictional force F2 causes variations, there is a problem that the reliability of the measurement cannot be said to be sufficient.

を短縮できる。According to such a configuration, the outer wall of the dedicated gauge 40 does not contact the inner wall of the opening 23a of the end wall side cover 23A at the time of measurement, and the friction force F
2 is gone. Therefore, the applied load is 100%
It is transmitted to the bearing roller 20B and the inner race 20C, and the applied load and the change amount of the gap amount have a linear relationship, and the shim thickness can be measured with high accuracy, so that the end play can be adjusted accurately. In addition, since the reliability of the measurement is high, the number of measurement points can be reduced, and the measurement time can be reduced.

き、測定時間の短縮化を図ることができる。As described above, according to the first aspect of the present invention, an intervening member is inserted between the outer race of the tapered roller bearing and the bean rig roller, and the outer wall of the outer race and the inner wall of the fixed portion are formed. Since the measurement can be performed without contact, the applied load is 10
0% can be transmitted, the reliability of the load and gap amount measurement data is improved, and the shim thickness measurement accuracy can be improved. Further, since the reliability of the data is high, the number of measurement points can be reduced, and the measurement time can be shortened.
