Deep groove ball bearing quality analysis
Compared with sliding bearing, deep groove ball bearing with sliding bearing the optimal compared, deep groove ball bearing bad
1, general conditions, the efficiency of the rolling bearing and liquid hydrodynamic lubrication bearing quite, but a mixture lubrication bearing is higher; 1, bear impact load ability is bad;
2, radial clearance are small, to the heart Angle contact bearings can be preloaded can be preloaded force eliminate clearance, the running high precision; 2, the heavy load bearing life is lower;
Three, for the size trunnion, rolling bearing than the width of the sliding bearing small, can make the machine axial structure compact; 3, vibration and noise bigger;
4, most of the rolling bearing can also be radial and axial load, the bearing structure simple; 4, radial than size sliding bearing;
5, consume less lubricant, easy to seal, easy maintenance;
6, need not useful nonferrous metals;
7, standardization degree is high, the bulk production, the cost is low;
