Description

city of Gretek: e to the cone crushers, pr1; le 15: e ;. for crushing various materials in the mining industry, the industry of construction materials and other branches of the national economy.

Known xoiiyciiaH crusher, containing the frame, l.zodnoj shaft, under the ground; A flabby cone, a crushing cone, is structurally complex.

Purpose ;; discovery - reported; e crushing cone of circular oscillations.

Zl CT; iraeTcn - / th due to the fact that: at the same time, the vertical vertical} th shaft is made from lead; a disk, one of the blades of which is inclined to the axis pr1: Bsdngsgs shaft, and a spherical support with a center 3 point, conscious of the axis of the drive hall "}; aklSN; Oh the drive disk capacity.

We offer lobil; sa depicted in the drawing.

One; -13 planes of the guided disc 3 are strictly perpendicular to the axis of the drive shaft and go back through the thrust plate to the frame. Another flat area facing the shot and the cone is inclined at an angle to the axis

front shaft. A crushing cone rests on this plane through a thrust bearing.

When the drive shaft 2 grows, it receives, e; i ;; e and drive 3. The inclined plane of the disk constantly changes its space in a circular motion relative to the center at the point O. The same Klebani makes a crushing cone, how it is pressed against the inclined blade of the drive disk. The friction forces arising between the pieces of the crushing material and the crushing material keep it from; 1р, nsrach:; for} ;;;;; |, the spherical olora 5 holds the x-nus in a position to the position.

The engine side of the engine is: water room: the torque is reported, which is worthwhile. 1ipend 1: cool to the iTcro axis of the shaft.

Thanks to the working plane of the drive disk, the circumferential force applied to the head plate, on the disk, is decomposed into two s: -setting: the normal pa6o4eii of the flatness and parallel to this plane.

Subject invention

Cone crushing, containing a frame, a driving vertical shaft, a fixed cone. Crushing cone, characterized in that, in order to communicate the crushing cone of circular oscillations, the drive vertical shaft is made with a drive disk, one of the planes of which is "inclined to the axis of the drive shaft, and a spherical support with a center at a point coinciding with the axis of the drive shaft and the inclined plane of the drive disk.
