　　When we use the cone crusher to crush and process materials, if the rotation speed of the moving cone is too large, it will directly affect the normal operation of the equipment. Next, let's analyze the reasons why the rotation speed of the cone crusher manipulator is too large.

　　1. When the cone shaft and the inner hole of the cone sleeve are not matched properly, the rotation speed of the cone crusher motor cone will be too large. Under normal circumstances, the actual inst ation height of the spherical tile, the fit clearance between the vertical shaft and the tapered sleeve, the fit gap between the eccentric shaft and the straight sleeve, and the wear of the spherical bush and the support plane of the fuselage, etc., will affect the spatial coincidence of the axis line. precision. This requires us to pay attention to the correct and standardized inst ation method in the process of inst ing the cone crusher.

　　2. When the gap between the main shaft and the cone sleeve is not appropriate, the rotation speed of the cone crusher motor cone will also be too large. Usu y, there are two main reasons for the too sm clearance between the moving cone spindle and the taper sleeve. One is that the newly inst ed taper sleeve has not been properly adjusted to the correct clearance according to the regulations. The second is that during the operation of the equipment, under the condition of insufficient lubrication, the taper sleeve is overheated, deformed and contracted. Therefore, correct inst ation and reasonable maintenance are important conditions to prevent excessive rotation of the cone crusher.

　　3. If the cone crusher is running for a long time, there is insufficient lubricating oil, or the lubricating oil is seriously polluted, etc., it will easily lead to poor lubrication of the friction surfaces such as the main shaft and the conical sleeve, spherical bearing and the spherical surface of the vertebral body. The wear between the parts is aggravated, and eventu y the rotation speed of the cone crusher motor cone is too large. Therefore, it is very important to do a good job of regular lubrication of the equipment.
