Inertial cone crusher with an upgraded drive

An inertial cone crusher comprising:

• a body with an outer cone resting upon a foundation via resilient dampers, and
• an inner cone arranged inside the outer cone on a spherical support, on whose drive shaft an unbalance weight is arranged using a slide bushing,
• wherein a center of gravity of the unbalance weight is adjustable relative to a rotation axis,
• wherein the unbalance weight includes a slide bushing connected to a transmission coupler,
• wherein torque from an engine is transmitted through the transmission coupler, and
• wherein the transmission coupler is a disc coupler including a driving half-coupler, a driven half-coupler, and a floating disc arranged between them,
• wherein the driven half-coupler is rigidly connected to the unbalance weight slide bushing, and the driving half-coupler is rigidly connected to a gear, and wherein the gear is rigidly connected to the counterbalance weight, with the driving half-coupler, gear, and counterbalance weight installed on the slide bushing so that the driving half-coupler, the gear, the counterbalance weight, and slide bushing form a single dynamic assembly,
• wherein the dynamic assembly is mounted, via a mounting disc, on a fixed rotation axis resting on a flange, while the flange is rigidly fixed in a bottom part of the body.
