Method for packing rolling elements in bearing, and use thereof

A device for packing rolling elements in a bearing, the bearing having a first ring and a second ring, and the rolling elements rotatable between a first ring raceway formed on the first ring and a second ring raceway formed on the second ring after assembly, a bearing ring fixing component is used to fix the first ring, preventing the first ring from shifting when subjected to radial compression;

• two first packing supports are disposed between the first ring raceway and second ring raceway at a predetermined circumferential angle, the two first packing supports dividing the bearing in a circumferential range into a compression zone lying within the range of the circumferential angle and a warping zone lying outside the range of the circumferential angle;
• and a bearing ring compression component is provided that applies a compressive load to a circumferential portion of the second ring that lies in the compression zone, the compressive load being directed towards the first ring in a radial direction, to force a radial gap between the first ring raceway and second ring raceway in the compression zone to decrease, such that a window suitable for packing the rolling elements is formed in the warping zone, the device comprising:
• a bearing loading platform for carrying, during assembly, the first ring and second ring that are substantially horizontally placed;
• a rolling element carrying ring, substantially having an annular structure, having a radial size that is substantially the same as a pitch circle diameter of the bearing, and designed to lift the rolling elements to a corresponding axial position between the first ring raceway and second ring raceway;
• and
• a bearing ring compression component, a bearing ring compression component is provided that applies a compressive load to a circumferential portion of the second ring that lies in the compression zone, the compressive load being directed towards the first ring in a radial direction, to force a radial gap between the first ring raceway and second ring raceway in the compression zone to decrease, such that a window suitable for packing the rolling elements is formed in the warping zone, once the first packing supports have been reliably positioned.
