Precise clearance rolling machine for extruded centered joint bearing

Abstract

The invention discloses a precise clearance rolling machine for an extruded centered joint bearing. According to the precise clearance rolling machine, a joint centered joint bearing which needs clearance regulation is arranged between a pressure roller and a bottom roller, the bottom roller drives the centered joint bearing to rotate, the centered joint bearing synchronously drives the pressure roller to rotate, and grinding expanding force is uniformly applied to the periphery of the centered joint bearing through the pressure roller, so that a clearance between a bearing inner ring and a bearing outer ring is regulated by controlling the grinding expanding force. Rollers abut against each other to uniformly apply pressure to the centered joint bearing between the rollers, so that the defects such as too great and uneven clearance scatter difference, low processing efficiency and poor precision of bearing inner and outer rings are solved, and therefore, collision damages caused on the outer ring by too great or small pressure in a clearance regulating process of the joint bearing are made up.

Description

technical field [0001] The invention relates to mechanical manufacturing technology, in particular to a precision rolling clearance machine for extruding radial joint bearings. Background technique [0002] Squeezed radial spherical plain bearings are mainly composed of inner and outer rings of the bearing. Through the sliding contact between the outer spherical surface of the inner ring and the inner spherical surface of the outer ring, it has high dynamic and static loads. When the inner ring and outer ring of the radial spherical plain bearing are assembled, the inner ring of the bearing is squeezed into the outer ring mainly through a mold such as a hydraulic press or a punching machine. After the extrusion is completed, the outer ring tightly locks the inner ring and cannot slide. In order to make the radial spherical plain bearing have an initial rotation effect and starting torque, the clearance must be adjusted. [0003] At present, most of the bearing manufacturer...

Problems solved by technology

But repeated tapping and rolling is not labor efficient

Moreover, for the radial spherical plain bearings processed by the above-mentioned various methods, the processing parameter data cannot generate effective records, and traceability search cannot be performed.
