Technical Field
[0001] The utility model relates to the technical field of bearing supports, in particular to a wear-resistant casting bearing support. Background Art
[0002] Bearing supports generally operate at room temperature and are non-moving parts. They primarily bear vibration loads and compressive stresses. To minimize these hazards, gray cast iron blanks should be used. The graphite structure's buffering effect on mechanical vibrations prevents the propagation of vibration energy, dissipating the vibration source within the graphite flakes. Gray cast iron also has strong compressive strength. In terms of casting performance, gray cast iron offers the best fluidity and the lowest shrinkage. Taking all factors into consideration, HT150 gray cast iron is the most suitable material. It is generally used to cast supports, bases, gearboxes, workbenches, and other components.
[0003] However, the existing wear-resistant cast bearing supports have the following problems during use: traditional bearing supports are used for a long time, and since the bearing supports mainly bear vibration loads, compressive stress, etc., the bolts at the connection position may slip, and due to their low strength and rigidity, they are easily damaged and have a short service life.
