Abstract
A differential gear casing of flower pot construction has an outer surface which is configured for receiving a crown wheel, whereby the crown wheel can be pressed onto the outer surface by different amounts for different applications. The outer surface is free from projections such that the crown wheel can be mounted on the outer surface from any axial direction. The outer surface defines a band on the differential gear casing and is parallel with a central axis of the differential gear casing. The crown wheel is secured to the differential gear casing using an axial weld line. In other embodiments, the crown wheel and/or a cover for the differential gear casing are secured in place using axial and/or radial weld lines.
