关节轴承是机械设备中一个普通而又重要的零件,它能使机件按要求的角度摆动或完成彼此协调的动作.过去,我们常见的是有装配缺口的关节轴承,但这种结构由于有缺口的存在,其承载能力的提高要受到限制.如果在相同的使用条件下,不增大轴承本身尺寸的话,则为了提高承载能力,采用 Spherical plain bearings are a common and important part of mechanical equipment that allows the parts to be swung or coordinated with each other at the required angle.It was common in the past to have a butt-joint bearing, but due to the fact that The existence of the gap, the carrying capacity of the increase to be limited.If under the same conditions of use, without increasing the size of the bearing itself, then, in order to improve the carrying capacity, the use of
