The outer casing or bearing housing of the shaft and equipment bearing; and other stressed parts in the bearing equipment; it is necessary to have the required rigidity; due to the deformation of these parts, the rolling of the rolling element is blocked and the bearing is damaged early. The outer casing and the bearing housing The wall of the hole shall have a satisfactory thickness; the cantilever of the bearing seat on the wall shall be shortened as much as possible; and the reinforcement shall be used to strengthen the support portion (Fig. A). If the outer casing is made of light alloy or non-metal; equipment bearing Steel or cast iron cups should be used (Fig. B). Fig. A Strengthening the rigidity of the bearing housing hole with reinforcing ribs B. Using the bearing housing hole of the steel liner for two bearing holes on one shaft; it is necessary to adhere to the concentricity as much as possible; to avoid excessive deviation between the inner and outer rings of the bearing. Oblique. The best way is to use the outer casing of the whole layout; and pull out the two holes of the equipment bearing once. If a bearing with different dimensions is installed on one shaft; the bearing hole on the outer casing should still be pulled out once; At this time, the liner can be used to make the bearing with smaller dimensions. When the two bearing holes are divided into two shells, the two shells should be combined to perform the boring. Recommend to friends comments close window
