Cone Crusher Main Shaft Sleeve
In order to form a lubricating oil film, manufacturing and assembly errors, thermal expansion and force deformation of components, determine the gap between the main shaft and the tapered bushing. If the gap is too small, it is easy to hold the shaft. If the gap is too large, the service life of the machine will be reduced and shock and vibration will easily occur. The best point of the clearance between the cone bushing and the main shaft is: the upper journal is large and the gap is small, and the lower journal is small and the gap is large. This is determined by the rotation of the main shaft of the cone crusher around a certain point in the space.
