What is the reason for the bearing locking produce ?
    点击数:5794         日期:2014/4/4
One important reason for bearing locking is caused due to overheating of bearing, specifically, processing when the rotating shaft, the bearing sleeve and the base has the tendency and defects:
(1) grinding of bearing outside diameter, tend to be error control in the upper deviation near.
(2) the axle bearing inside diameter, tend to be error control in the lower deviation near. The above two kinds of tendency, the bearing is in interference fit with the diameter of the inner and outer rings of the bearing, deformation will make the bearing clearance becomes small.
(3) seat processing using the U-turn car process, the two ends of the frame check radial runout tolerance is 0.15mm, stop the end face runout tolerance is 0.1mm, the precision of the machine tool and other reasons, the end face runout error more, most of the 0.20mm ~ 0.40mm. The motor assembly, bearing and the bearing sleeve will generate an eccentric, closer to the outer ring of the bearing deformation caused by.
The above three points, in extreme cases, can cause bearing clearance into 0, then back to the occurrence of bearing locking phenomenon
