FSU-20 Bearing Housing Cap 06/21/23

The Bearing Housing Cap

Model Version: 9.2

Material: AISI 4130 Steel, annealed at 865C

Yield Strength:460 MPa

Validation: June 21st 2023

Fixtures

  • Virtual Wall also on the countersunk hole

  •  

Loading

Fz:

  • The bearing housing cap is used at 4 different nodes:

    • Front and Rear UCA

    • Front and Rear LCA

  • Since they are identical at each of those points, the max Fz between those 4 nodes will be used for each case to test the part

    • if it can withstand the largest force, than anything weaker than it should be fine

      • the max Fz always occurs at the LCA nodes

  • The force occurs where the bearing wall interacts with the housing cap

Recommendations

The Bearing housing cap is fine, and could probably be made from a lower yield strength material if that's cheaper/easier to acquire
