托辊辊体存在的工艺缺点
托辊辊体存在的工艺缺点
存在的工艺缺点是:
The existing technological disadvantages are as follows:
1)轴承座和管子采用焊接工艺造成了轴承座热变形,轴承座的内孔与管子的平行度受到了影响,也就是两端的轴承座的同心度得不到保障
1) the welding process of the bearing seat and the pipe causes the thermal deformation of the bearing seat, and the parallelism between the inner hole of the bearing seat and the pipe is affected, that is to say, the concentricity of the bearing seat at both ends is not guaranteed
2)由于是手工安设轴承座,轴承座内孔与设备的顶头公差较大(为了便于安设),轴承座的外径与管子止口孔的公差也较大,实际制作的辊体,无法保证保定平面设计培训 保定空调维修 保定管道通风 包装盒定做 化粪池模具 废旧电缆回收 不锈钢铸件 图2中所标注的同心度。
2) since the bearing pedestal is installed manually, the tolerance between the inner hole of the bearing pedestal and the head of the equipment is large (for the convenience of installation), and the tolerance between the outer diameter of the bearing pedestal and the pipe stop hole is also large. The concentricity marked in Figure 2 cannot be guaranteed for the actual roll body.
