The technological process of welding of worn out parts have bearings
This technology is used in the repair of bearings. First, perform the necessary preparatory operations, the quality and thoroughness of the implementation of which will depend on the strength and durability of the deposited layer. The recommended sequence of operations is as follows:
- For defective areas are removed the remains of the old babbit, which uses oxy-fuel cutting torches;
- The body of the liner in preparation for surfacing: the surface is thoroughly cleaned of oxides and scale by using a hard metal brushes;
- Is degreasing, which is prepared for surfacing, after which it is washed with hot water;
- All holes in a filler item capped, then tinning the surface with the use of fluxes.
The surfacing and subsequent machining of a bearing housing is performed as follows. Set the value of the allowance required for the subsequent machining, followed by welding alternately each ear separately. Next remove surface oxides and slags, and also earlier set of technological plugs.
The company Electrocentury-steel implements at affordable prices a variety of brands of Babbitt alloys. The supplier provides timely delivery of products to any place specified by the consumer.
Machining of the weld surfaces and quality control
After overlaying is prisalivaya surfaces with subsequent review of the field fit. The contacted parts are thrown «in the paint», and using the probe, control the actual value of the gaps. Install the tightening bolts are not required. The result is the possible displacement of the bearing halves, which should not exceed 0,02 mm.
Making quality made scraping the liner is placed in a lathe and they check the detail on the likely radial runout: it should not exceed 0,3…0,5 mm. Next is turning the working surface of the liner to the dimensions specified on the drawing node.
When the final quality control is made by visual inspection of the surface. It should have a silvery-white color, no yellow (it indicates overheating of the material during the surfacing Babbitt, and the process must be repeated). Not allowed the presence of pores, cavities, and foreign inclusions of the surface. The final verification stage is a kerosene sample: the product for a few hours placed in a container with kerosene, then remove, carefully wipe with a rag, RUB chalk the joints and put under load. If the control of exposure period on the chalk marks are found traces of kerosene, the adhesion of the babbit metal is incomplete, and the product requires pereplavka.
When the positivity of the results of the control liner is subjected to a final milling cutting end surfaces.
To buy the necessary item of different Babbitt alloys at manufacturer’s prices, the company offers Electrocentury-steel. The supplier ensures prompt delivery of products to customers.
