Dolomite Crusher “Speeding”

The So-Called “Speeding”

When the Dolomite Crusher is in no-load, the taper sleeve on the thin side of the eccentric bushing is in contact with the main shaft. The friction torque generated at the contact point drives the cone to rotate in the same direction (unsynchronized) as the eccentric bushing. If the frictional moment and the reverse frictional moment of the bowl-shaped bearing acting on the spherical surface of the cone are equal, the constant rotation of the cone can be maintained. For some reason, the balance of the cone is broken, its rotation speed is getting faster and faster, and finally “flying”, this is what we call “speeding”.

6 Reasons For “Speeding”

In any case, the “flying car” will have a taper sleeve burn, and most of the burns occur on the side of the thin side of the eccentric bushing, and it occurs more than 1/4 of the length from the upper mouth. It can be said that the origin of the “speeding” accident is between the main shaft and the taper sleeve.
