How to adjust gear clearance of hydraulic cone crusher

Hydraulic cone crusher

1. If possible, the counterweight side of the large gear on the eccentric sleeve should be placed directly above the small gear.

2. Use a crowbar or other means to pull the pinion gear toward the drive side so that the thrust end face of the pinion gear is tightly attached to the end face of the bearing sleeve inside the transmission shaft frame. NOTE: Belts or flexible couplings must be loosened before measurement.

3. Rotate the transmission shaft slightly until a large gear tooth is in the vertical position.

4. Use a jack or crowbar to press the eccentric sleeve toward the pinion gear side to eliminate the gap between the eccentric sleeve of the cone crusher and the frame bushing, so that the large and small gears are in a close position. Use a jack to push the pinion horizontally. The jack force and crowbar force are only enough to eliminate the gap, and do not deflect the eccentric sleeve.

5. Keep the large gear in the above position for measurement. The gap value should be measured at three equal parts and then the average value should be taken. The average value shall comply with the above provisions.
