RENCOL® Tolerance Rings to simply fix the stator to the shaft / housing.
The dimensions between the stator and housing are able to vary, usually due to thermal expansion but also manufacturing tolerance stack-ups, whilst the waves apply a consistent retention force.
Saint-Gobain’s engineers use finite element analysis techniques to perform modal analysis of stator mount assemblies. They can tune the dynamic stiffness of the RENCOL® products so they can isolate vibration or shift natural frequencies out of the operating ranges.
The RENCOL® product is assembled by applying an axial force with a press to insert the stator into the aluminium housing. Once assembled, no curing or settling time is required.
