Analysis of the three misunderstandings in the process of non-standard bearing assembly

Analysis of non-standard bearing assembly process of three error sources: bearing | last updated: - 2020 07 - 15 three misunderstandings in the process of analysis of non-standard bearing assembly we on non-standard bearing installation and assembly of the installation surface and the place has a very strict requirements. If you don't pay attention to the assembly environment, the influence of leads to iron filings, burr and other foreign bodies with to the interior of the non-standard bearings, bearing in time for normal operation of the noise and vibration, and even damage to the raceway and rolling body. So, at the time of installation of non-standard bearings, must ensure that the mounting surface and environment cleaning and hygiene. At the time of the non-standard bearing lubrication, not oil daub the more the better, inside the bearing and oil in bearing chamber if too much will cause excessive oil mixing, produce the high temperature. The best oil filling quantity best keep on bearing one-half to one-third of the internal space. Bearing clearance shall undertake choosing according to the condition of application, rather than the radial clearance as small as possible. Non-standard bearing radial clearance basic is divided into five categories: 2, 0, 3, 4, 5. Their clearance is growing up. 0 class for the standard clearance type, use with general operation conditions, the normal temperature and common interference fit. If at high temperature, high speed and low noise low friction's special working conditions to choose the larger radial clearance. If the accuracy is higher, so suit to choose the smaller radial clearance. And those separated type bearing on clearance requirements is not high, due to the non-standard bearing rotation need to absorb a certain amount of load, and bearing fit and load will produce certain elastic deformation.
