Bearing Defect
Bearings are designed to reduce friction and support loads, enabling the rotation of various machine parts. However, over time, bearings may experience wear and tear, defects and failures, leading to increased downtime, costly repairs and even accidents. This example compares a bearing with a defect with a regular bearing.
Model of the Bearing with a Defect
The example compares two TIMKEN NU 313 EJ bearings connected to a shaft, one regular and one with a defect. The system is put in motion using a power source that applies a torque to the system.
The bearing on the right has a defect.
Simulation Results
The top graph shows the applied defect forces, while the middle graph displays the roller forces. The force on the roller with the defect is lower than the force on the regular roller. The bottom graph shows that the total forces are greater when the roller coincides with the defect.
The defect applies a force (500 N) at the 12 o’clock point on the rollers.
