How are the inner and outer rings of the centripetal joint bearing processed?
I. processing methods:Generally used slotted outer ring radial joint bearing and its processing method, the bearing is composed of outer ring, inner ring and sealing ring. The inner and outer rings are made of carburizing steel, both of which are soft in heart and hard in appearance.
Two, brief introduction of joint bearing:The structure of the joint bearing is simpler than that of the rolling bearing. It is mainly composed of an inner ring with an outer sphere and an outer ring with an inner spherical surface. Joint bearing generally used for swinging movement of the lower velocity (i.e., angular) because the sliding surface is spherical shape, can also be used as a tilt movement in a certain range of angles (i.e. aligning movement), the support shaft and the shaft casing hole concentricity is larger, can still work normally.
The bearing processing method is that the outer ring adopts double slit type in the symmetrical position of bearing outer ring slot position respectively to drill a hole of crack, and then along the guide hole on both sides to end milling two arc crack respectively, and then on the outer ring surface carburizing heat treatment, the outer surface comprises two crack hole and crack arc surface hardness reached 54HRC ~ 62HRC, using slotted normal processes, bearing outer ring can along the crack hole and crack position of arc section, split into two semi-circular outer ring, and the crack neatly. The bearing has the characteristics of shock resistance and wear resistance.
