In-situ machining of a bearing housing
Dimensional recovery of a bearing housing without stripping the equipment, with a compensating bush manufactured to suit.
Execution
The sequence applied and the engineering decisions taken
The order below reproduces how the work was actually carried out, including the points where the condition found required a change of scope.
- Measurement of the housing on site to quantify the wear and the ovality.
- Strategy defined: machine in situ to a regular dimension and compensate with a bush, avoiding stripping the equipment.
- Machining rig mounted on the equipment itself, referenced from the working axis.
- Housing machined to the defined dimension, with in-process dimensional control.
- Compensating bush manufactured in the workshop, with the interference calculated for the fit.
- Bush fitted, bearing installed and alignment verified.
Comparison
Condition before and after the intervention
Drag the slider to switch between the two recorded conditions.
- Before
- Housing worn and oval, with the bearing no longer properly retained.
- After
- Housing machined in situ and compensated with a bush, alignment verified.
Result
What the intervention delivered
The recovery was completed in five days, without stripping the equipment and inside the shutdown window available. Sending the unit to a workshop would have meant at least three weeks out of service.
