A technique of a disk profile creation taking into account that soil does not get poached in a zone of deep chord and the possibility of ensuring its sliding on a curvilinear surface of operation sector. Basic data for construction horizontal, cross-vertical, longitudinal-vertical projections are diameter of a disk, angle of attack, running depth. Depth of the course images a chord of disk dip on cross-vertical and longitudinal-vertical projections of a disk. The disk sphere which excludes crumple of a vertical wall of a furrow at its movement is designated on the horizontal projection. Criterion of disk efficiency is a possible soil sliding along a curve of longitudinal-vertical projection between the lowermost point and the point excluding crumple of the furrow vertical wall and located on the deep chord. The parameter of a curve of possible sliding can be defined taking into account that the sum of multiplications of tangent efforts to a projection of a trajectory of the movement of an elementary platform less than zero. Taking into account the received value we can construction the sliding curve on the longitudinal-vertical projection in a zone of operating surface. Points of intersection of the sliding curve with the generating lines of longitudinal-vertical projection are moved by horizontal transfer on a piece of an interval of the horizontal projection. On three points we create a profile of a disk on height of a placement of the generating lines.
Thus the proposed technique is developed and it allows the disk with the spherical or flat bottom to be created.
