众所周知,滚动轴承以其所共知的特性为人们所认识和使用,而滑动承轴因其没有定型产品不为人们所重视,仅以套类零件称之,忽略其特殊的使用性能。笔者认为从在建筑机械上的应用就可看出其优越性的所在,并具有充分发挥优越性的条件,如在钢筋切断机、砼搅拌机等机械的应用可以证实这一点。 1.结构简单,费用低滑动轴承主要分为整体式和剖分式两类,常用的就是整体式,只是一个套,最多结构上多个台阶式加工出油线、油槽等,加工是比较容易的;剖分式加工比整体式复杂,但满足了安装的特殊要求,相对也不是复杂的。由于其具有结构简单,制作容易,工时费用低,特别是材料 It is well-known that rolling bearings are known and used by people with their well-known properties, and sliding bearing shafts are not valued by people because of their non-finished products. They are only referred to as sets of parts and neglect their special performance. The author believes that the superiority of the application can be seen from the application of the construction machinery, and the conditions for giving full play to the superiority, such as the application of the steel cutting machine and the ramming mixer, can confirm this. 1. Simple structure, low cost Slide bearings are mainly divided into two types: integral type and split type. The commonly used one is the integral type, which is only one set. It can process oil lines and oil sumps on multiple steps at most, and processing is relatively easy. The split processing is more complex than the overall type, but it satisfies the special requirements of the installation and is not relatively complicated. Due to its simple structure, easy fabrication, and low labor cost, especially materials
