(1) the structure of bearing
There are four Phi 12 hole of the bearing seat of the base, and have certain roughness and other fittings fixed limiting function, the above Φ 12 hole is dripping mouth, is the bearing and the bearing seat with the play the role of lubrication
(2) the bearing technology
1) casting needs effective treatment to eliminate internal stress of casting, and the structure and properties of uniform
2) the material is HT200, the grade of grey cast iron with high hardness, high strength, combined with the bearing seat, with this model can meet the requirements of
3) for Φ 16 ↓ 5X4 roughness of 1.6, size 85 3.2, the bottom 3.2, hole of Φ 62.5 has a surface roughness of 0.6 to 0.005 and its roundness, axis relative to the coaxial 125 Phi degree of tolerance for 0.015 requirement
4) accuracy requirement is to ensure the coordination to achieve a good fit to work with, and can meet the requirements of the use of performance.
