Description

The device is intended for rolling bearing testing machines. Consists of . a working device positioned above the mechanical part of the test machine in a support structure attached to the leg supports provided with positioning elements at the lower ends to which they are attached to the stage of the mechanical part or to the substrate of the test machine. The device is usable in rolling bearing test rooms.

The invention solves the control and diagnostic unit of the rolling bearing test machine.

Rolling bearing test machines consist of both a mechanical part and a control device; diagnostics. In this device are located individual control elements, further signaling and protection elements together with measuring and recording devices. This control and diagnostic device is made up of several sub-assemblies or forms a whole and is predominantly located outside the mechanical parts of the test machine or is exceptionally attached to the upper or side parts of the machine. · Placement outside the testing machine requires a considerable · increase in the ground plan area of the test room. Mounting directly on the machine results in a deterioration in the function of sensitive measuring and recording instruments. Transmitted vibrations from the tester also result in considerable failure of these instruments.

The aforementioned disadvantages are largely eliminated by the operating and diagnostic unit of the tester with the operating, measuring, signaling, securing and diagnostic elements according to the invention, which is characterized in that the operating device is located separately above the mechanical part. test machine and is built into a supporting structure attached to the webs. The webs rest on the substrate of the test machine together with the mechanical part and are positioned on the frame of the mechanical part or on the substrate of the test machine by means of positioning elements. It is a further object of the invention to have a spigot on the support structure and an extension for the passage of the connecting elements on the mechanical part. The throat and the extension engage with each other with will and a resilient member is arranged between them.

The control unit according to the invention achieves a significantly longer service life of the measuring instruments, a much more accurate reading of the measured quantities and easier operation and maintenance. The whole facility occupies a considerably smaller built-up area of the testing room.

The device according to the invention is shown in the drawing, which is a schematic view of the overall arrangement.

The working device 1 with the control, measuring, signaling, belaying and diagnostic elements is located separately above the mechanical part 2 of the testing machine and is incorporated in the support structure 3. The support structure 3 is attached to the webs 4, for example by screw connection 5 The uprights 4 rest on the test machine base 6 together with the frame 8 of the mechanical part 2 and are connected to the test machine frame 8 or the base 6 of the test machine by means of positioning elements 7 consisting in the illustrated arrangement of double-stud bolts with tightening nuts. The positioning elements 7 may consist, for example, of a rubber bushing with front screws, a screw with a nut, an inserted flexible or rigid shaped member, for example a pin and a sleeve and the like. The gate 10 is fastened to the supporting structure 3 and to the mechanical part 2 an extension 11 is provided for the passage of unconnected connecting elements, in particular electrical conductors. The neck 10 and the extension 11 engage each other with play. A resilient member 9 is disposed between the neck 10 and the adapter 11. This resilient member 9 may be formed by a rubber ring, a plastic ring, a flat bellows spring, and the like. . ·. .. ·. .
