Outer spherical ball bearing
Outer spherical ball bearing belongs to deep groove ball bearing, and the rolling element inside is steel ball; Its outer ring surface is spherical, so it is called outer spherical ball bearing.You can use spherical ball bearing turning machine to do it.
The outer spherical ball bearing is more convenient to use than the general deep groove ball bearing, which is mainly characterized by simple loading and unloading and adjustable center. The standard tolerance of the outer spherical ball bearing is: add inside and subtract outside, and add tolerance for the inner diameter, so as to ensure the lightness when matching with the shaft; Each set of outer spherical ball bearing is not used alone. It must be installed inside the bearing seat. The outer spherical bearing seat has various shapes, so it is suitable for a variety of structural positions after overall matching.
Outer spherical ball bearings can be divided into three categories according to the locking mode with the shaft:
1. Outer spherical ball bearing with jacking screw: it is characterized in that when matching with the shaft, the jacking screw is used to jack on the shaft, so as to play a fixed role, but the matching environment requires a small vibration range. This kind of outer spherical ball bearing is relatively common and is widely used in textile machinery, ceramic machinery and other manufacturing industries.
2. Tapered outer spherical ball bearing: it can bear greater load than the outer spherical ball bearing with jacking screw.
3. Outer spherical ball bearing with eccentric sleeve: it is characterized by a certain eccentricity at the upper end of the bearing, and the eccentric sleeve with the same eccentricity is matched with it. This kind of bearing can also be said to be a special bearing, because it is mainly used in agricultural machinery (harvester, straw returning machine, thresher, etc.). This kind of outer spherical ball bearing is mainly used in the structure with violent jump. The cooperation of eccentric structure can effectively reduce the violent jump.
