The attachment is a drive designed by me to see whether the bearings in each part are reasonableThe gears are helical gears
Spherical roller bearings 22312 to 30312. The installation direction is opposite to the 30311. Use and bear axial force. SUC210 bearings instead of N210 cylindrical roller bearings, favorable temperature changes, long axis compensation, so that the long axis is not bent.
Bearing selection is based on your design axis depends on the size of the bar, are related to the data table behind the mechanical design guide book, the size of your fixed axis, can be found in the corresponding bearing, no need to consider whether to support, just think of that kind of bearing is appropriate
I can't see the details in the drawing, but it seems to be a wrong design! ?If the axial force below is left, it seems that the axle is ok. But the upper axis of the axial force is right, it is wrong, the axis will move to the right, the need for the right of the 210 bearings to bear the axial force, that is not good. ?If the axial force below is right, it is not right and there is no place to bear the axial force. And the upper axis of the axial force is to the left, the need to rely on the left end of the cover to bear the axial force, is not ideal. ?In addition, if the need for the use of self-aligning bearings, 210 should also be a heart adjustment to meet the logic.
