大齿圈变形,主要有两种:齿距突变和齿圈扭曲。这里就齿圈扭曲重点介绍如下。大齿圈扭曲变形是常见的,当变形严重时,将引起球磨机强烈振动和异响,造成与之相齿合的轴齿轮齿断裂及轴承损坏等严重事故。产生大齿圈扭曲变形的因素较多,除了大齿圈铸造内应力未采取适当处理予以消除外,尚有加工精度差、安装不符合技术标准等原因。但是,由于上述原因产生扭曲变形而引起剧振,则往往在齿圈安装后不久就会发生。实际上,
Deformation of gear ring, there are two main: a sudden change in pitch and gear ring distortion. Here to gear ring distortion are described below. Gear ring distortion is common, when the deformation is serious, it will cause strong vibration ball mill and abnormal sound, resulting in phase with the shaft gear tooth fracture and bearing damage and other serious accidents. There are many factors that cause distortion of gear ring. In addition to the internal stress of the gear ring casting is not properly treated to eliminate, there are processing accuracy is poor, the installation does not meet the technical standards and other reasons. However, due to the above reasons distorted deformation caused by the vibration, it is often installed soon after the ring gear will occur. In fact,
