Will the installation of bearings in the bearing seat, bearing and gland need to leave the expansion gap? Bearing running temperature 70 degrees.
And work environment, and many other factors, right? I asked, there are the following statement:1. the bearing and gland shall be provided with a thermal expansion gap. The specific clearance shall be confirmed according to the conditions of use. The installation code for centrifugal pumps should be 0.02~0.05mm.2. bearings have three kinds of clearance, namely, original, fit, work clearance. The bearing capacity of the assembled shaft is radial bearing, thrust bearing and centripetal thrust bearing are single or paired installation. In the bearing assembly, pairs of bearings should be fixed at one end, leaving a gap of not greater than 0.1mm, leaving expansion, otherwise the bearings will be heated at the time of operation, affecting the operation cycle of the bearing.3. tapered roller bearings not only can not compress, but also to stay a certain gap. The value of the specific gap can be found in the manual. The adjusting method is that the adjusting shim is arranged between the bearing cap and the box body or the end cover of the vehicle
No, it should be tight fit
The question is not comprehensive, bearing no single, double installation: one is killed, the bearing outer ring and the gland crushed, with a round nut on the bearing inner ring and shaft; the other end of the bearing axial movement, the outer ring of the bearing gland to leave the expansion gap, but the bearing inner ring and shaft with a round nut crushed, which is commonly used the configuration, tapered roller bearings can disassemble the bearing on this end.
