Rolling ball bearings. How are steel balls put into bearings?
The bearing inner ring to the outer side close to, then the bearing outer ring slightly extrusion deformation, steel balls fill, to push the inner ring, the outer ring to loosen the extrusion pressure, ball mounted inside, in the steel ball distance apart, with the cage, cage nail riveting after molding
First, the inner ring of the bearing is closed to the side of the outer ring, and then the outer ring of the bearing is slightly squeezed and deformed. After the steel ball is filled in, the inner ring is pushed upwards, and the outer ring extruding pressure is loosened, and the steel ball is loaded in.
There are generally three ways:The first is suitable for relatively small bearings, in addition to the last one can be installed directly, when the last grain into the use of a special mold, the outer ring slightly squashed, you can put the last grain in it;The second is suitable for larger bearings, generally use hot installation, heating the bearing outer ring, the steel ball can be directly loaded at room temperature, the temperature difference of about 60-70 degrees, the problem is not large;The third method applies to full load ball bearings, in the outer ring or inner ring at the end of a semicircle shaped ball groove, you can push the ball into.
