Compound pendulum HPC Cone Crusher is commonly utilized in several industries, and it's large crushing ratio, economical electrical power, protected and trustworthy performance, so it really is perfectly obtained by consumers of all ages.

Compound pendulum jaw crusher is equipped with two pairs of bearings: 1 pair is rack bearing between the rack along with the eccentric shaft; the other pair is shifting jaw bearing between the movable jaw plus the eccentric shaft. The 2 pairs of bearings transfer the load generated in crushing course of action to the rack, therefore, the structural layout has to be acceptable. Here, this paper mostly describes how to ascertain the interior clearance from the bearing.


There may be only radial clearance in spherical roller; the radial clearance might be divided into 5 teams in accordance on the regular, which has been modified while in the manufacturing facility through the company. The clearance known as the authentic clearance. Getting assemblyed the bearing, the first clearance will be minimized. As for going jaw bearings, eccentric shaft works by using interference healthy assembly with it. Following heating going jaw bearing, the inner ring expands; the growth on the inner ring will minimize the first bearing clearance.

As for rack bearings, we often established withdrawal match to fix the bearing internal ring and eccentric shaft, the axial motion on the withdrawal sleeve determines the reduction of bearing radial clearance. The bearing handbooks commonly provide the least and greatest radial clearance reduction to diverse bearings. The least radial clearance reduction is always to protect against the withdrawal sleeve loosing and getting relative rotation with eccentric shaft or bearing internal ring. The greatest radial clearance reduction will be to protect against large deformation of the bearing internal ring.
