Note for bearing use
Time：16-04-26
First, the use of notes
Rolling bearings in the precision parts, so when in use requirements accordingly cautious attitude, both use the high performance bearing, if used improperly, can not achieve the expected performance results. Therefore, the use of the bearing so that should pay attention to the following matters:
1, keep the bearing and the surrounding environment clean. Even if the invisible smile dust into the bearing, it will increase the bearing wear, vibration and noise.
2, the use of the installation should be careful, do not allow a strong punch, do not allow the use of direct percussion hammer bearings, does not allow the transfer of pressure through the rolling body.
3, the use of appropriate and accurate installation tools, as far as possible to use special tools, to avoid the use of cloth and short fibers and the like.
4, prevent bearing corrosion directly with hands to pick up the bearing to fully wash hands sweat, and coated with high quality mineral oil for operations, paying particular attention to rust in the rainy season and summer.
Two, bearing fit
1, the choice of cooperation
The inner diameter and outer diameter of the rolling bearing are manufactured according to the standard tolerance, the inner ring of the bearing and the shaft, the matching tightness of the outer ring and the seat can only be realized by controlling the tolerance of the shaft neck and the tolerance of the seat hole. With the bearing inner ring and shaft using the base hole, with the outer ring of the bearing seat hole by shaft system. Proper selection of fit must be aware of the actual load conditions, operating temperature and other requirements of the bearing, while in fact it is very difficult. As a result, most of the cases are selected according to the use of precision. Industrial washing machine for valve inlet pump
2, load size
Between the ring and the shaft or shell won the amount depending on the size of the load, the heavier load the larger won the amount, lighter load with a smaller win.
