Abstract
A receiving housing of a hydraulic tensioning device for a traction mechanism drive in an internal combustion engine, having an opening that extends along a longitudinal axis for receiving a piston that is implemented for deflecting a tensioning rail of the traction mechanism drive. The receiving housing is a cast component, and the opening comprises an inner contour having an inner surface that comprises at least first segments and inclines for removing the workpiece from the mold in the opening. The second segments include surfaces that are directed into the inside of the opening and are aligned in parallel with the longitudinal axis. A sliding core is also provided that has an outer contour that is complementary to the inner contour of the opening of the receiving housing and fits into the opening. A traction mechanism drive and tensioning device having a receiving housing of this type are also included.
