Spherical roller bearing is in the two groove of the inner ring and outer ring raceways between spherical bearing assembly, a drum shaped roller. Spherical roller bearing with two rollers, mainly bear radial load, but also can withstand axial load in either direction. There is a high radial load capacity, especially suitable for heavy load or vibration load, but can not bear pure axial load. The outer race of the bearing ring is spherical, so its aligning performance is good, can compensate the coaxial error.
Spherical roller bearings are divided into: cylindrical hole, tapered bore. Hole taper cone respectively of 1:12 rear code for K spherical roller bearing (153000 or 113000) and the 1:30 rear code for K30 spherical roller bearing. This kind of bearing shaft with a conical distribution, inner ring along the axial movement of the bearing can adjust radial clearance.
The main application of the holder: stamping steel plate reinforced type holder (suffix E, domestic rarely). Stamping steel plate type holder (suffix CC), glass fiber reinforced polyamide 66 holder (suffix TVPB), machined brass two piece holder (suffix MB). Machine processing Brass integral type holder (suffix CA), vibration stamping steel plate holder (suffix JPA). Vibration occasion brass cage (suffix EMA). The same structure, the code on the bearing or different.
Main uses: paper machine, speed reducer, railway vehicle axle, rolling mill gear box bearing, roller mill, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer and vertical self-aligning bearing seat.
Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings. The curvature center of the outer ring roller surface is consistent with the bearing center, so it has the same regulating heart function as the automatic aligning ball bearing. When the shaft and the outer shell are bent, the axial load of the two directions can be automatically adjusted. The radial load capacity is large, it is suitable for the situation of heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or use a tight set, the dismantling of the cylinder installed on the cylinder axis. Holder using sheet metal stamping holder, polyamide forming holder, and copper alloy vehicle holder.
For self aligning bearings, when the shaft hole of the shaft is arranged in the shaft of the bearing, the middle mounting ring is used to prevent the outer ring from tilting and rotating. It should be remembered that some of the size of the self aligning ball bearings of the ball out of the side of the bearing, so the middle of the installation ring should be recessed to prevent damage to the ball. A large number of bearings are generally used in mechanical or hydraulic pressure into the method of installation.
For separable bearings, the inner and outer rings can be installed separately, which simplifies the installation process, especially when the inner and outer circles need to cooperate. When the inner ring is installed in the bearing box with the outer ring, we must pay attention to check whether the inner and outer rings are correct, so as to avoid the scratch bearing rolling track and rolling parts. If the cylindrical and needle roller bearings without inner ring flange edge or side flange of the inner ring, the recommended installation sleeve. The outer diameter of the sleeve should be equal to the diameter of the inner ring F, and the tolerance standard of machining should be d10. Needle roller bearings is best installed using the mandrel.
