Vulcanizing fans now use 2316 double row self-aligning ball, but the bearings are often damaged, I ask, what kind of strength of a little larger bearings can replace the current use of bearings? Please know the answer ~ thank you ^.
Spherical roller bearings (roller bearings) under axial load self-aligning ball bearing under axial load.? ? ?Spherical roller bearings can bear radial load in addition to the very high, which can withstand the effect of heavy axial loads in two directions. The dual row self-aligning ball bearings can bear larger radial load, and can only bear certain axial load.Self-aligning ball bearings can bear large radial load, also can withstand the axial load. This kind of bearing outer ring raceway is spherical shape, it has a self-aligning performance, the axial force bending or tilt of the inner ring and the outer ring center line center line relative inclination of not more than 1 degrees to 3 degrees, the bearing can still work. The utility model is mainly used for occasions where the span of the shaft supporting point is large and the coaxiality is difficult to guarantee.
Spherical roller bearings (spherical roller bearings) instead of self-aligning ball bearing is better.
Self-aligning ball bearings are cylindrical and conical in two. The taper of the taper inner hole is 1:12 or 1:30. In order to strengthen the lubrication performance of the bearing, the annular oil groove and three oil holes are machined on the outer ring of the bearing.Self-aligning ball bearing 12 series and 22 series bearings allow the tilt angle of 2.5 degrees, 13 series and 23 series bearings allow the tilt angle is 3 degrees, when the bearing is used in full tilt conditions must ensure that the bearing and peripheral parts have sufficient clearance; when the speed increases, the bearing noise of tilt there is increasing trend. Because of noise restrictions, the actual bearing angle of tilt angle is much smaller than the maximum possible; for bearings with a tapered bore, after installation is difficult to accurately measure the bearing clearance, bearing with tapered bore so the installation requires some experience and technology; with polyamide frame bearing temperature retention should be less than 120 DEG C.Spherical roller bearings have two rows of rollers, in the outer ring with a common spherical raceway, and two inner ring raceway, at an angle with the bearing axis (Figure 1). The spherical center of the outer raceway is located on the axis of the bearing. Therefore, the bearing is a self-aligning bearing (Fig. 2) which is insensitive to centering errors between the shaft and the bearing seat, which may be caused by factors such as shaft misalignment. The spherical roller bearings are well designed and can bear heavy axial loads in two directions in addition to the high radial load.
Self-aligning ball bearing is mainly used in large span coaxial bearing point, can not guarantee the occasion, but the speed limit is not high (like 2316 you are using in the highest speed limit of grease lubrication for the case of 3200rpm), wind speed machine is very high (I don't know how many specific vulcanization fan you said), if both ends in 2316, in two different bearing error under the condition of large, high-speed operation will damage the bearing. In fact, like high-speed occasions, in the case of coaxial guarantee, light load with deep groove ball bearings, heavy duty cylindrical roller bearings can be used.
