1. What is an outer spherical bearing and what is its purpose?
Although its basic performance should be similar to that of Deep Groove Ball Bearing, because these bearings are mostly used for relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or when the shaft is long, the deflection is large, the bearing itself is not accurate enough, and some structures are rough, the actual performance of Deep Groove Ball Bearing of the same specification should be marked with a considerable discount. For example, for throughshafts with large stiffness differences and large deflections, external spherical ball bearings with top screws are used. This type of bearing has sealing rings on both sides to strictly prevent dirt from entering. An appropriate amount of lubricating oil has been added before leaving the factory, and there is no need to clean it before installation., There is no need to add lubricant when the top screw on the protruding end of the bearing inner ring is tightened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load. Standard for outer spherical bearing seats.
The performance of an outer spherical ball bearing with an eccentric sleeve is basically the same as that of an outer spherical bearing with a top screw, but the top screw is not on the inner ring, but on the eccentric sleeve. The inner hole of the tapered hole outer spherical ball bearing is a tapered hole with a taper of 1:12, which can be directly installed on the tapered shaft or installed on the shoulder less optical shaft with the help of a locking sleeve, and the bearing clearance can be adjusted.
Self aligning bearings are preferred for applications that require simple equipment and components, such as agricultural machinery, transportation systems, or construction machinery.
Mainly used to withstand combined radial and axial loads mainly consisting of radial loads. Generally, it is not suitable to bear axial loads alone. This type of bearing can be installed with inner rings (complete set of rollers and cages) and outer rings respectively. Lock it up. This type of bearing does not allow the shaft to tilt relative to the casing, and will generate additional axial force under radial load. The axial clearance of this type of bearing is closely related to its normal operation. Axial clearance is too small, resulting in an increase in temperature; When the axial clearance is large, the bearing is prone to damage. Therefore, special attention should be paid to adjusting the axial clearance of the bearings during installation and operation. If necessary, pre interference installation can be carried out to increase the stiffness of the bearing. Where are outer spherical bearings used.
