Rigidity and concentricity of bearing equipment parts
| /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089'; |
Shafts, housings or housings for bearing bearings and other parts in bearing equipment; it is necessary to have a rigid stiffness. Deformation of these parts will prevent the rolling body from rolling; premature bearing damage. The housing and housing should have a satisfactory thickness; The bearing cantilever on the wall should be shortened as much as possible; and the ribs should be used to enhance the rigidity of the bearing. For example, the surgical use is made of light alloy or non-metal; the steel or cast iron liner is used.
Two supported seat holes on one shaft; it is necessary to adhere to the same concentricity; avoid excessive deflection between the inner and outer rings. The best choice is to use the outer casing of the whole layout; and the two holes of the equipment bearing are pulled out at once. When a bearing with different dimensions is mounted on one shaft; the bearing housing hole on the outer casing should still be ejected at a time; then the liner can be used to make the bearing with smaller dimensions. When the two bearing housing holes are divided into two outer casings When it is up; the two shells should be combined for boring.
