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

introduction：abbaGuide slide lubrication method When using a guide slide,Good lubrication must be provided。If used without lubrication,The rolling part will wear out faster,Therefore, its service life will be shortened。 Guide slide lubrication has the following effects∶ 1) Reduce friction between moving parts,This prevents coking and reduces wear。 2) An oil film is formed on the rolling surface to reduce the stress on the surface,And prolong rolling fatigue life。 3) Cover the metal with an oil film to prevent rust。In order to give full play to the function of linear guide,Please provide lubrication according to the specific conditions of use。Even linear guides with sealed baffles,The internal lubricant will also gradually leak out during operation。 therefore,The system needs to be lubricated at appropriate intervals according to the conditions of use。Linear guide rails mainly use grease or sliding surface oil as its lubricant。 The requirements to be met by lubricants generally include∶ 1) High oil film strength 2) Low
