To measure good or bad about the quality of the precision of rolling bearing analysis

1, separable bearing ( Accuracy) This is a kind of ring rolling bearing can be installed in a separate, when both ring with tight fit its advantage is very outstanding. Separable bearings include four-point contact ball bearing, two and a half circle of double row angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, thrust ball bearings, thrust cylindrical roller bearings, thrust spherical roller bearings. It also introduce the integral bearing a type:) Integral bearing, are: deep groove ball bearings, single row angular contact ball bearings, self-aligning ball bearings, peng roller bearings and spherical roller bearings. 2, in most cases the application of general size precision and the rotating precision of the rolling bearing is enough. Bearing need higher precision when demand a higher level, 3, no neutral compensation no neutral in processing shaft neck surface or bearing with surface, especially with surface processing is not done in the middle of a pack card. When using the bearing seat also can produce in the wrong, For example: flange bearing or vertical bearing) 。 Due to work load bending deformation in the shaft, which can lead to bearing inner and outer circle, also can appear in the wrong. Self-aligning bearing can undertake compensation right and inclination, for example:, peng roller bearings, self-aligning ball bearing radial and thrust spherical roller bearings. This kind of bearing has a concave spherical outer ring raceway, rolling body and inner ring can rotate inside. These compensation axis deflection Angle at the centre of the bearing capacity depends on their own type, size and load conditions. Spherical bearing and outdide circle of thrust ball bearing has a spherical bearing surface: when installed in the hollow spherical seat can be adjusted to compensate deflection Angle. 4, speed single bearing friction especially low, therefore can achieve the highest speed. This kind of bearing has only bear radial load of deep groove ball bearing and angular contact ball bearings can withstand the combined load. Improve the dimensional precision, rotating precision of the bearing and cooperate with the precision of the parts, the lubrication cooling way, using a special form of cage can improve bearing allows speed. Low noise in a small motor operation, office equipment and household appliances and other general requirements to's running noise. 5, conical hole with conical hole bearing can be installed directly to the cone shaft neck ( For example: high precision structure of single row and double row cylindrical roller bearings) 。 When installing this kind of bearings can adjust out of a given radial clearance. Most with a conical bore self-aligning ball bearings, cylindrical roller bearings and spherical roller bearings are available through a set of installation set to the cylindrical shaft neck. This type of bearing special is easy to install and remove. 6, stiffness of bearing stiffness is usually directed bearing the force needed to produce certain elastic deformation. Machine tool spindle and pinion shaft bearings are required to have high stiffness. As a result of the rolling element and raceway contact condition is different, the rigidity of the roller bearing
