FAG bearings, inner ring guide, outer ring guide, roller guide respectively. What do you mean?
3, inner ring bootThe inner ring is generally a rotating ring, and provides a rolling body to drag the torque in the rotation. If the bearing is unstable or the load is light, it will skid. The cage is formed by the inner guide, oil film in keeping the guide face frame, due to the friction of oil film in the inner region of non load retainer to drag force so as to increase the holder of additional torque rolling body, and can prevent slipping.
2, outer ring bootThe outer ring is generally stationary, with outer guides leading to lubricating oil entering the guide face and raceway. High speed gear box for oil mist lubrication, with the rotation of the inner guide will take out oil.The outer guide generally used for high speed and stable load conditions, such as medium bearing auxiliary column under axial load, a fixed value, little change in the speed of the ball rotation, rotation of the holder is not caused by imbalance.
3 guide methods of bearing holder, roller guide, outer ring guide and inner ring guide:1, rolling bootThe standard structure of the general design of the rolling body guide, such as short cylindrical roller bearing, the rolling guide, the holder and the inner and outer sides are not in contact, the holder can be used, but in the high speed rolling speed increased, the rotation is not stable, so the rolling body guide is suitable for medium speed and medium load., such as gear box bearing.
