Method of producing a workpiece forming at least one bearing eye
A method of producing a workpiece forming at least one bearing eye is described, which is divided in the region of the bearing eye along an intended fracture point through a fracture separation, the bearing eye being coated with an anti-friction coating after assembly of the parts. In order to achieve a high load capacity, it is suggested that the bearing eye be processed for a precise fit after assembly of the parts obtained through the fracture separation of the workpiece, before the anti-friction coating is applied to the processed bearing eye surface in a thickness corresponding to the final dimensions.
1. A method of producing a workpiece forming at least one bearing eye, which is divided in the region of the bearing eye along an intended fracture point by a fracture separation, the bearing eye being coated with an anti-friction coating after assembly of the parts of the workpieces obtained through the fracture separation,
characterized in that the bearing eye is processed for a precise fit after assembly of the parts obtained through the fracture separation of the workpiece, but before the anti-friction coating is applied to the processed bearing eye surface in a thickness corresponding to the final dimensions, the anti-friction coating is galvanically deposited in a galvanic bath onto the bearing eye surface in a thickness corresponding to the final dimensions, and before the galvanic deposition of the anti-friction coating, the fracture gap between the parts of the workpiece is sealed in relation to the galvanic bath.
2. The method according to claim 1 , characterized in that the fracture gap is filled with water, to which additives are added if necessary to slow the diffusion speed.
3. The method according to claim 1 , characterized in that the fracture gap is sealed using a wax.
4. The method according to claim 3 , characterized in that the wax is dissolved in a solvent having low viscosity and low surface tension.
5. The method according to claim 4 , characterized in that the wax is heated to seal the fracture gap.
6. The method according to claim 1 , characterized in that a stretchable film made of plastic is inserted between the parts of the workpiece to seal the fracture gap.
