Axial Loading System of Vertical Telescopic Double Row Tapered Roller Bearing

Abstract

The present invention provides a vertical telescopic double-row tapered roller bearing axial loading system, including a platform, a loading tray, etc.; the double-row bearing includes an inner ring I, an inner ring II, a spacer ring, an outer ring and two sets of rolling elements; There is a groove above the platform, and the loading tray, loading plate and bearing tray are installed in the groove, the bearing tray is connected with a guide rod, and the guide rod is slidingly connected with the loading tray; the bottom of the loading tray is connected with a loading ball head, and the loading ball head It is connected with the telescopic rod of the loading cylinder; there is a loading plate above the loading tray, and the loading plate is in contact with the lower end surface of the outer ring; there is a rotating mandrel above the double-row bearing, and the rotating mandrel is connected to the inner hole of the double-row bearing during testing. connected. The present invention adopts the vertical telescopic type, and the spacer ring and inner ring II are separated from the inner ring I due to gravity during detection, thereby ensuring that the measurement of the bearings in the above list is not affected by the spacer ring and inner ring II; the detection of the upper bearing is completed Then just turn the double row bearing over and measure the other row.

Description

technical field [0001] The invention relates to the technical field of dynamic quality detection of bearings, in particular to an axial loading system of a vertically telescopic double-row tapered roller bearing. Background technique [0002] At present, due to the special structure of double-row tapered roller bearings, the dynamic quality inspection of its finished bearings is basically in a blank state, especially for the units that use this type of bearings, the dynamic quality judgment of this type of bearings is still manual. + Judging by hearing and hand feeling, the judgment method is backward, and the false detection rate is very high. The invention not only provides necessary means for the dynamic quality detection of railway freight car bearings, but also fills up the blank of dynamic quality detection of such bearings in China. [0003] According to the GB / T24610.3-2009 / ISO15242-3:2006 standard, an axial load needs to be applied to the tapered roller bearing dur...

Problems solved by technology

[0005] According to the above proposals, other existing bearing dynamic quality inspection systems are mostly horizontal test benches, which can only be tested in pairs or disassembled during the inspection process, and there are technical problems such as low efficiency and damage to the tested bearing structure.
