Thin section crossed roller bearing device needs attention to some matters, such as the the shaft circle and the vertical axis of the middle line degree bearing device accurate or loaded situation after the anti-introduce the following skills approach. ball screw bearing
Popular joint venture of thin-walled cross-roller bearings and shaft for the transition of the joint venture, the seat and the bearing hole joint venture popular the gap joint venture. Two-way bearing bottom bracket circle should be fixed on the shaft, in order to avoid the associated axis migration shift. The bearing device approach, popular situation changes the status of the axis majority, and thus the inner ring and the shaft of the joint venture is to win the joint venture, the joint venture of the bearing outer ring and bearing chamber gap joint venture.
1) standard (G) tolerance bearings;
2) radial bearings, thrust bearings only axial load only radial loads;
) = 0.1C (C-bearing basic dynamic load rating);
4) the rigidity of the bearing seat and the shaft;
(5) The normal lubricating and cooling conditions.
Thin section crossed roller bearings operating under load conditi ons in 0.1C rolling element and raceway contact between the surface of the contact stress increases, causing the bearing operating temperature increases, the performance of the lubricant relative deterioration Therefore, bearing the Limiting speed will be reduced accordingly.
For C / = 10 range of little reduction in the limit speed, and therefore can not be considered, namely f1 = 1 value. slim bearing
For withstand the combined load effect of radial bearings, due to its increased number of load bearing rolling elements, the frictional resistance increases, increased heat, lubrication and cooling conditions deteriorate, but also increases the force acting on the holder, therefore, must bearing type and size of the load angle, thin-walled cross-roller bearings Limiting speed multiplied by a lower coefficient f2 be adjusted.
