Surfacing of worn out places at bearings of sliding
This technology is used in the repair of bearings. Initially, the necessary preparatory operations are performed, the quality and thoroughness of the performance will depend on the strength and durability of the deposited layer. The sequence of operations is as follows:
- On the defective places, the remnants of the old Babbitt are removed, for which gas-oxygen cutters are used;
- The body of the liner is prepared for surfacing: its surface is thoroughly cleaned of oxides and scale with the use of rigid metal brushes;
- The surface is degreased, which is prepared for surfacing, after which it is thoroughly washed with hot water;
- All technological holes in the deposited product are muffled, after which surface tinning with fluxes is performed.
Surfacing and subsequent machining of the bearing housing is performed as follows. Set the value of allowance, which is necessary for subsequent processing on machines, after which the surfacing is carried out alternately each of the liners separately. Further, surface slags and oxides are removed, as well as previously supplied process plugs. Supplier Evek GmbH offers to buy babbits of domestic and foreign production at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
Processing of welded surfaces
After surfacing, surfaces are grounded and then the fit is checked. The contact details are placed «on the paint», and, using the feeler gauge, monitor the actual value of the gaps. Installation of tightening bolts is not required. As a result, a possible shift of the bearing halves is established, which should not exceed 0.02 mm. Having convinced in qualitatively executed shabrenija, the loose leaf place in the lathe and there check a detail on probable radial palpation: it should not exceed 0,3… 0,5 mm. Further, the working surface of the insert is pierced to the dimensions indicated in the drawing of the assembly.
At final quality control, a visual inspection of the surface is made. It should have a silvery white color, without yellowness (it indicates overheating of the material during the deposition of Babbit, and the process must be repeated). The presence of pores, shells, as well as foreign surface inclusions is not allowed. The final stage of the test is a kerosene test: the product is placed in a container with kerosene for several hours, then it is removed, carefully wiped with rags, rubbed with chalk joints and placed under load. If after the control period of exposure to chalk marks traces of kerosene are found, then the coupling of babbitt with the metal is incomplete, and the product requires re-surfacing. If the results of the inspection are positive, the insert is subjected to final milling with the cutting of the end surfaces.
