| description | A choice of the sizes and form of a disk is made for the set operation conditions on the basis of geometrical ratios between parameters of a disk and their admissible values developed by practice. Except the crumbling and turning ability of a disk the add factors influencing on its geometrical and power parameters are non-crumple condition of a vertical wall of a furrow and steady raising of layer on a curvilinear surface of operation sector. Basic data for construction horizontal, cross-vertical, longitudinal-vertical projections is diameter of a disk, an 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 a is possible soil sliding along a curve of longitudinal-vertical projection within limits of the lowermost point and a point excluding crumple of the furrow vertical wall and located on a chord of deep. 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. The disk profile with the spherical or flat bottom should be create at the level of generating lines of cross-vertical projection taking into account the intervals placed on a perpendicular to the center of diameter of a disk of a horizontal projection. |
