Spherical roller bearings are between the inner ring with two raceways and the outer ring with spherical races; the bearings are equipped with drum rollers. The center of curvature of the raceway surface of the outer ring is common with the center of the bearing; The same self-aligning function of the self-aligning ball bearing. When the shaft and the shell are deflected; the axial load can be actively adjusted and the two directions can be applied. The radial load can be large; it is suitable for the situation with heavy load and impact load. The inner diameter of the ring is a bearing with a tapered bore; it can be directly installed. Or the adapter sleeve can be used to disassemble the cylinder on the cylindrical shaft. The cage is made of steel stamping cage, polyamide forming cage and copper alloy cage.
Regarding self-aligning bearings; when inserting the bearing with the shaft into the shaft hole of the box; using the center device ring can prevent the outer ring from skewing and rotating. It should be remembered that the ball of the self-aligning ball bearing of some dimensions Stand out on the side of the bearing; so the center device ring should be recessed; to prevent damage to the ball. Many bearings are usually mechanical or hydraulic press-fit method.
Regarding the separable bearing; the inner ring and the outer ring can separate the device; this simplifies the device process; especially when the inner and outer rings need to have an interference fit. In the case where the inner ring has been mounted in place, the shaft is loaded When the bearing housing is in the ring; it is necessary to pay attention to check whether the inner and outer rings can be correctly centered; to prevent the bearing raceway and the rolling part from being scratched. If the cylindrical and needle bearing are selected, the inner ring or the side without the flange rib is used. The inner ring of the blue edge; advocate the use of the device sleeve. The outer diameter of the sleeve should be equal to the diameter of the inner ring raceway F; the public service specification for machining should be d10. The outer ring needle roller bearing is the best use of the mandrel device.
