根据前面一系列的计算结果，要选定轴承的类型为带密封圈的单列向心球轴承（

According to the previous series of calculation results, the type of bearing to be selected is a single-row radial ball bearing with sealing ring (GB279-64). The bearing models are selected as 18504 and 18505 respectively. This kind of bearing mainly bears radial load, when the speed is higher When the axial load is not large, it can replace the thrust ball bearing to bear the pure axial load. The sealing ring can prevent dirt from entering the bearing from one side, because the other side is designed with a bearing cover, which can be lubricated and greased by oil Lubrication reduces friction, reduces contact stress, absorbs vibration, prevents corrosion, heat dissipation, etc. Such bearings are mainly used in parts with higher sealing requirements.

According to the results of the previous series of calculations, the type of bearing to be selected is a single-column centrifugal bearing (GB279-64) bearing type with sealing ring, selected as 18504 and 18505, respectively. When the axial load is not large, it can replace the thrust ball bearing to withstand pure axial load, the seal ring can more closely prevent dirt from invading the bearing from one side, because the other side is designed with bearing cover, can reduce friction through oil lubrication and grease lubrication, reduce contact stress, Absorb vibration, prevent rust, heat dissipation, etc., such bearings are mainly used in high-sealing components.

根据前面一系列的计算结果，要选定轴承的类型为带密封圈的单列向心球轴承（GB279—64）轴承型号分别选为18504和18505.这种轴承主要承受径向载荷，当转速较高，轴向载荷不大时，可以代替推力球轴承承受纯轴向载荷，密封圈能较严密地防止污物从一面侵入轴承，因为另一面设计加了轴承嵌盖，可通过油润滑及脂润滑降低摩擦力，减小接触应力、吸收振动、防止锈蚀、散热等，此类轴承主要用在密封要求较高的部件中。<br>
