Abstract
Inertia cone crusher for crushing materials includes a body with an outer cone and an inner cone arranged inside, on whose drive shaft an unbalance weight is provided with the aid of a slide bushing and connected via a transmission disk coupling to a combined moving dynamic assembly comprising a counterbalance weight and a counterbalance weight slide bushing, the assembly connected to a gear transmission and a motor, and has an improved plain journal bearing. The plain bearing is installed between the flange and the counterbalance weight, bearing the load from the crusher's moving part, and includes a base ring and an upper ring, the base ring having a spherical bottom surface and its mating recess on the flange's top surface. The bearing enables the moving dynamic assembly's rotation around the axis, using a hydrodynamic sliding mode, with radial oil slots additionally provided on top surface of the base ring.
