The angle of uniline is exposed to the axial load that the ball bearing can only bear a direction, while bearing radial load, will cause additional axial force. And can only limit the axle or outer cover in the axial displacement of a direction. The contact angle that the angle contacts the ball bearing is 40 degrees, so can bear the axial load greatly. Design on it is it been to contact separating ball bearing horn,inside and outside differ shoulder level of both sides enclosed. For improving load ability of bearing,will pairs of shoulder of one side among them the processing is getting lower relatively, thus let the bearing put into more steel balls.
It is the master’s radial and axial union load and moment load that pair lists the angle and is exposed to the ball bearing and bear greater radial load, limit the axial displacement of two respects of the axle. Use mainly for, restrain axle from and pair list horn contact in the ball bearing and outer lane tiltable and limited in the the intersection of outer cover and two-way axial part of displacement, allow the angle of inclination to depend on internal interval, bearing size, inside design of the bearing and act on strength and moment on the bearing, allow the angle of inclination to guarantee to produce the too high additional stress in the bearing the most largely. If store in the bearing, between the outer lanes in the angle of inclination, will influence the life-span of the bearing, cause the bearing to operate the precision to drop at the same time, the noise of operating increases. Pair list horn, contact ball bearing, adopt nylon, keep the shelf or brass entity keeping the shelf generally. Pair lists the angle should notice, though the bearing can bear the two-way axial load while contacting the installation of ball bearing, but when one side holds ball gaps, should notice that don’t let the main axial load be passed by the ditch of one side with gap. When the bearing uses should pay attention to, make without put the intersection of ball and side of gap roll one bear main load.
