Abstract
A bearing system which is for suspending the swing frame of a conveyor grate in a swinging manner on a support structure. Two elastic spring rods are arranged next to each other in a common plane of swinging. The spring rods have a first end clamped in a fixed manner on clamping points of a first structural component. The second ends of the spring rods are clamped in a fixed manner to connection points on a rigid coupling system. The rigid coupling system is connected with the second structural component. The spring rods are inclined toward each other in the swinging plane. The coupling system is connected with the second structural component so that it can be tilted in the swinging plane via a flexible connection. Because of the inclination of the spring rods, when they are jointly deflected, one of the spring rods always describes a downward arc and the other an upward arc. It is possible to find on the coupling system connecting the lower ends of the spring rods an area that substantially is carrying out an at least quasi-linear movement. The invention guides the swing frame in a substantially linear way.
