Description,

The fatigue life of the adapter sleeve

1. The basic concept of the adapter sleeve fatigue life The general meaning of the adapter sleeve fatigue life refers to the fixation under a certain technical state (structure, process state, fit, installation, clearance and lubrication state, etc.)

2. The sleeve is operated in the actual use state of the host until the rolling surface fatigues and cannot meet the requirements of the host.

3. The total value of the relative rotation times of the inner and outer rings (shaft, seat ring) of the tightening sleeve-the total number of revolutions.

4. When the rotation of the adapter sleeve is more generally constant or known, the fatigue life can be expressed by the total number of operating hours corresponding to the total number of revolutions. In addition, it should also be noted

5. There are many factors that affect the fatigue life of the adapter sleeve, and not all It is estimated or eliminated through standard test conditions, which causes the actual fatigue life of the adapter sleeve to be very discrete.

6. Therefore, the expression parameter of the fatigue life of the adapter sleeve is the rated life L10, and the meaning of L10 in the ISO recommended standard R281 It is clearly stated as follows: "

7. The number of identical sets of adapter sleeves is sufficient, and the rated life L10 is expressed in revolutions (or hours when the rotation speed is constant. 90% of the adapter sleeves are in fatigue spalling) It can reach or exceed this number of revolutions (or hours) before it occurs. "
