Description

Grinding media.

Milling machines with roller action rotatable grinding bodies against two ring-shaped surrounding them and axial grinding tracks which are rotated relative to one another are known. It is also known on such grinding machines that the inner grinding path through radially or to subdivide substantially radially directed cuts into sections and the sections to strain, thus the pressure exerted by them when rotating as a result of centrifugal force is exerted in the radial direction against the grinding media is increased.

When rolling the grinding media from one section of the inner grinding track to the neighboring section with these machines, as a rule causes a harmful impact. The invention aims to remedy this disadvantage to eliminate that the sections of the inner grinding track are so resiliently arranged, that their ends are opposite to the central part and essentially independent of it in radial direction Can give in direction resiliently.

The drawing illustrates in horizontal Cut a fragment of a grinding machine of the type in question with two nested Grinding tracks and cylindrical grinding media in between.

With ι the fixed outer grinding track, with 2 a grinding body and with 3 a section the rotatable inner grinding track referred to by means of an S-shaped bent leaf spring 4 is connected to a radially displaceable load piece 5, which is firmly connected to the machine shaft Rails is to be thought of as sliding.

Characterized in that each section 3 of the inner grinding path by a spring 4 with the associated radially displaceable load body 5 is connected, the whole grinding track is made resilient in sections, so that each section or section, both in front and behind, while the machine is in operation give in and move horizontally within certain limits, d. H. in the direction can move freely transversely to the machine axis, whereas the section is prevented from moving in the vertical direction, d. H. in the direction parallel to the machine axis. Of the The resilient body is shown in the drawing as a relatively tall and narrow S-shaped Steel piece formed, but can also be carried out in other ways. On the Drawing is the piece with the help of bolts and screws by means of nuts 6 attached to the grinding track section and the loading piece ..

Claims (3)

Patent Claims: 1. Grinding machine with movable grinding tracks between two mutually rotatable grinding tracks Grinders, whose inner, annular, grinding track consisting of sections below the influence of centrifugal force is applied against the grinding media, characterized in that that the two ends of each section of the inner grinding path in relation to its central part and thus also to any load piece of which are resiliently resilient in the radial direction, wherein the middle part of the section remains practically unaffected. 2. Grinding machine according to claim 1, characterized in that the connection of each section of the inner grinding path with its load piece with the help a resilient intermediate piece attached to these two parts happens that a resilience of the two ends of the section in the radial direction allows, while the distance of the central part of the section from its loading piece remains practically unchanged. 3. embodiment of the arrangement according to claim 2, characterized in that the resilient intermediate piece is designed as a leaf spring, its on the machine axis vertical cross-section S-shaped, and its generatrix is parallel to the machine axis.
