FIELD: mining.
SUBSTANCE: main shaft of the cone crusher comprises an elongated main shaft having an outwardly facing surface extending transversely to narrow inwards to the longitudinal axis of the main shaft to form a converging region and reduce the cross-sectional area, a sleeve comprising an elongated axial wall whose thickness decreases in the direction from the top end of the main shaft to the lower end, and a radial wall extending perpendicularly or transversely to the axial wall. The bushing is installed solely by contact with an interference fit between the inwardly facing surface of the bushing and the outwardly facing surface of the main shaft. Cone crusher is characterized by the presence of the above main shaft and bushing.
EFFECT: improves the convenience of mounting and dismantling the main shaft.
