Abstract
A connection for preventing relative movement between coupled members in a clamped joint. In particular, ring gear/differential housing members are connected across a roughened surface finish providing protrusions and allow positive load transfer without slippage. Different methods are proposed to achieve the roughening, or surface modification, of the backside of the ring gear surface, and this design provides increased frictional coefficients without adversely affecting performance of the differential assembly. The simplicity and low cost of this connection makes it particularly useful for a wide variety of these bolted assemblies.
