The Installation Methods of Cone Crusher Bearing

Cone crusher like the jaw crusher and impact crusher, is widely used in the mining machinery, it is mainly used for thin broken of some materials, the particle size of the material is smaller, it belongs to fine crushing. Its bearings in it play a crucial role. Now we will introduce the installation of bearing. The thrust bearing function of cone crusher is: supporting air eccentric shaft, reducing the air eccentric shaft running resistance. At the same time, the accuracy of the install directly affects the gap of gear meshing clearance to ensure the gap of reasonable air eccentric shaft sleeve and the spindle, avoiding the phenomenon of the "Speed".

Guarantee the installation accuracy of the thrust bearing on the conical crusher is necessary to the normal operation of the crusher. Installation according to the following steps:

1. thrust uranium bearing installation shall be in accordance with the order of the contact surface. 
2. to make three jaw plates set at the bottom cover should be smooth, lower head inside if there are casting burr and the rest of the sand, you must clean up, and then pour lubricating oil and parallel to the three jaw board plane level position to detect whether it is smooth.
3. then in turn install the medium board and round board, the detection method still can use the above method
4. finally install the empty eccentric shaft, spherical tile frame and main shaft. When the empty eccentric shaft is hoisted, big gear weight should be placed above small bevel gear, making the bevel gear outer end alignment, spherical tile after installation, you should make spherical bearing pedestal and base use as far as possible interference fit; it is appropriately tight and should not be loose. In the period, three data have been measured:
• cone umbrella tooth gap
• main shaft and taper sleeve gaps
• empty eccentric shaft face and spherical tile rack bottom clearance

To understand this, when we use the cone crusher, we should pay close attention to cone crusher’s bearings, check its each index to ensure the normal work.
