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
A numerically obtained example of push out force as a function of temperature including manufacturing tolerance effects. The RENCOL® Tolerance Ring used in this example retains more retention force than the press fit solution, when subject to increasing temperatures.
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.
Assembly force as a function of displacement. The peak force required to assemble the RENCOL® tolerance ring solution is much lower than the room temperature press fit solution.
