Abstract
Seizing-up between a shaft and its bearing is caused incidentaly, so it is difficult to make clear the seizing phenomenon. But it well-known that the mechanism consists of two process, being born of seizing-nucleus and it growth.
On the 1st report, I investigated on the procees of growth of the seizing-nucleus on the shaft surface. In this report, I studied the generating incentive of seizing-nucleus with statistical method, because seizing is an accidental-phenomenon as describes before.
Useing an equipment of cross cylinder type, the expreiment was carried out to measure the runing time for seizing up a shaft under several conditions, and to make the histgrams of those times for analysing as statistical-phenomenon.
The results are as follows:
(1) The histgrams are distributed logarithmiconormaly, and the standard deviations of them are proportional to the means of runing time to seizing-up.
(2) The movements to generate seizing-nucleus relate to the products of preventing resistance being on the sliding surface and runing time wihout seizing-up.
(3) The results of (1) and (2) may lead to the theorization of runing-in.
(4) The load and the roughness of shaft suraface act inverse-proportionally upon the movements of generating seizing-nucleus.
(5) The oil film has a large effect upon the results, and it is difficult to maintain it at the same condition, so no-good to infrence seizing-up after smol times of the experiments.
