Abstract
A blade assembly of a motor grader includes a drawbar frame adapted for mounting to the motor grader and a circle frame adapted for mounting a blade thereto. A number of shoe assemblies are mounted to the drawbar frame in a circular array and support the circle frame and blade for rotational movement against the drawbar frame. The circle frame includes a circular frame portion and a number of ring gear segments mounted to the circular portion in a circular array. Each of the ring gear segments includes gear teeth adapted for engaging drive means of the drawbar frame. The circular portion and the ring gear segments define an assembly slidingly received between the shoe assemblies and the drawbar frame. The circular portion is slidingly received against the shoe assemblies, and the ring gear segments are slidingly received against the drawbar frame. Bearing members are disposed between the circular portion and the shoe assemblies and between the ring gear segments and the drawbar frame.
