The outer spherical ball bearing is a variant of the deep groove ball bearing in practice; its characteristic is that the outer diameter of the outer ring is spherical; it can be fitted into the corresponding concave spherical surface of the bearing seat to achieve the effect of self-aligning.
Although its fundamental function should be similar to that of deep groove ball bearings; however, most of these bearings are used in relatively rough machines; the positioning of the device is not accurate; the axis of the shaft and the hole is poorly centered; or the axis is long and the deflection is In the case of a large class; and the accuracy of the bearing itself is not high; some layouts are also rougher; therefore, the functional practice is equivalent to the same standard deep groove ball bearing to be fitted with a suitable buckle. For example: the outer spherical ball with the top wire The bearing is applied to the through shaft with large difference of rigidity and deflection; the bearing has sealing ring on both sides; it can avoid the intrusion of dirt tightly; the excess lubricant is filled when leaving the factory; there is no need to remove the device before the device; no need to add lubricant; bearing The top wire screw on the protruding end of the inner ring is fastened on the shaft. The axial load of the promise shall not exceed 20% of the additional dynamic load.
The outer spherical ball bearing with the partial pain sleeve has the same function as the outer spherical bearing with the top wire; only the top wire is not on the inner ring; instead, it is on the partial pain sleeve. The inner hole of the tapered spherical outer spherical ball bearing is the belt 1: 12-cone tapered bore; can be mounted directly on the tapered shaft; or with a tight bushing on the shaft without the shoulder; fine-tuning the bearing clearance.
Spherical bearings are preferred for applications where equipment and components are required; for example, in agricultural machinery, transportation systems or construction machinery.
It is primarily used to accept radial and axial combined loads based on radial loads; it is generally not advisable to accept axial loads alone; such bearings can be separated from the inner ring of the device (with full set of rollers and holders) and the outer ring. The bearings do not allow the shaft to be skewed relative to the outer casing; additional axial forces occur under radial load commissioning. The axial clearance of the bearing is large and the catastrophic sputum ∈ ∈ 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保 保rigidity.
