The transmission part 18 is arranged on the upper side of the base part 1. The transmission part 18 and the transmission part gear 17 Fixedly connected, the gear 17 of the transmission part is meshed with the gear 16 of the eccentric sleeve.

In the laminated hydraulic cone crusher, the eccentric sleeve 14 is in interference fit with the moving cone 13 .

In the laminated hydraulic cone crusher, the intersection point O of the center line of the eccentric sleeve 14 and the main shaft 15 and the common center O' of the upper spherical friction disc 10 and the lower spherical friction disc 11 are all on the center line of the main shaft 15, But not at the same point.
