Made In

Subject to the analysis was a tribological kinematic pair consisting of shaft and sleeve, both made of C45 steel. The elements were joined by pressing with the 0.02 mm tolerance. The shaft was subjected to the finishing and strengthening treatment consisting in induction hardening. The tribological kinematic pair made in such way was tested on a fatigue testing machine, which permitted obtaining a rotational bending moment. Macroscopic investigations of the unhardened shaft demonstrated, on the shaft surface, the traces of fretting wear in the form of a ring of the uniform width comprising the entire axle seat circumference. Based on the test results, it may be concluded that the use of the shaft induction hardening process has caused the reduction of fretting wear development compared to shafts without additional treatment. In this case, Wear traces in the form of small diameter ring comprising the entire shaft circumference are observed on one side of the shaft axle seat.

Bearing Ball

Ball bearing life test, once the failure specimen ball fatigue, if not timely shutdown, will lead to a series of chain reactions caused by the fault processing is not seasonable, serious word may also lead to the damage of equipment. Therefore the vibration test is very important to accurately determine the specimen failure, ball. In this paper, the vibration test for bearing fatigue testing machine, the test results to be real-time and accurate judgment sample ball failure.
