introduction：Oscillating loads and variable loads。Sometimes the direction and magnitude of the load cannot be determined with certainty，For example, in high-speed rotating machinery，Except that the weight of the rotor is a fixed load in the direction，There is also the rotating load caused by the unbalanced mass，If the rotating load is much greater than the fixed load，The resultant load is still the rotating load;And if the rotating load is much smaller than the fixed load，The resultant load is oscillating load。No matter the rotating load or the swinging load，Its size and direction are constantly changing。And in a variable working state，Some rings may be subjected to rotating loads，Its a fixed load，Sometimes it is oscillating load。This kind of load is called indefinite load。Oscillating loads and variable loads should be treated the same as rotating loads in coordination，Too loose fit will cause damage to the fit surface。A ring and shaft or seat hole rotating in relation to the direction of load，Transition fit or interferen
