为保证滑动轴的正常工作,套外径和孔为过盈配合,其内径和轴为动配合。我们在维修工程机械中,一般根据套内外径和与套相配件的内外径,以及要求的过盈量及配合间隙,修配各种套。当套外径和孔内经过盈配合后,使套内径产生收缩量,所以在配套时必需考虑这一值,使组装前的套孔内径相应加大。
To ensure the normal operation of the sliding shaft, sleeve diameter and hole for the interference fit, the diameter and the shaft is a dynamic fit. We are in the maintenance of construction machinery, generally based on the diameter of the sleeve and the inner and outer diameter of the set of accessories, and the required amount of interference and with the gap, repair a variety of sets. When the outer diameter of the sleeve and the hole after the interference fit, the sleeve diameter shrinkage, so the package must take into account this value, so that before the sleeve diameter increase sleeve.
