Cone crusher, bearing plate, and kit of bearing plates

摘要

The present disclosure relates to a gyratory cone crusher with a first (5) and a second (7) crushing shell defining a crushing gap (3). The first crushing shell is arranged to gyrate around a vertical axis, in order to crush material entering the crushing gap, and is vertically supported by a thrust bearing (15) comprising a first (19) and a second (21) bearing plates defining a spherical sliding interface (25). One of the bearing plates has one or more cooling and/or lubricating grooves at the sliding interface, each groove defining a channel, extending from the centre of the sliding interface to the periphery thereof. In order to obtain a uniform distribution of grooves, the cooling/lubricating grooves (41) are in the form of one or more spirals extending from the centre of the sliding interface to the periphery thereof. The disclosure further relates to a bearing plate and a kit of bearing plates involving such a bearing plate.
