一、怎祥选择滚动轴承运转机构或工具按上轴承后就能灵活的运转,并提高其机械工作效率.但是,由于各种机械构造不同,它们的转数和所承受的负荷(不变的,带振动的,带冲击的等)以及工作环境等也就各不相同.因此为了正确的选择轴承,就必须考虑这些因素.可以参考下面的几种方法来选择合适的滚劫轴承的类型.(一)手摇和脚踏两用水车拐轴两支点轴承,应选用单列向心球轴承或单列向心短元柱滚子轴承为佳,因它只承受径向负荷.适宜采用上述两种类型轴承的工具甚多,如改良后的石磨拐轴,单,双铧
First, how to choose the rolling bearing operating mechanism or tool according to the bearing will be able to flexible operation, and improve the efficiency of its mechanical work.But due to the different mechanical structure, their number of revolutions and bear the load (unchanged, Vibration, shock, etc.) and working environment, etc. Therefore, these factors must be taken into account in order to select the proper bearing, and you can refer to the following methods to select the appropriate type of bearing. A) hand and foot water wheel axle two fulcrum bearings should be used single row radial ball bearings or single row radial spherical roller bearings is better, because it only bear the radial load. Suitable for the use of the two types Many tools for bearings, such as the improved stone grinding axis, single, dual-hua
