摘要：
The utility model refers to agricultural machinery, in particular to the working bodies of discs and harrows.A cultivating spherical disk made of high-quality structural steel having a continuous cutting edge, a sharpening on the convex side of the working surface and a layer of hardfacing with a hard alloy, the hardfacing layer being made on the convex and concave sides of the working surface of the disk in the form of a series of identical arc- -4 mm, the concave side of the side surface of the weld beads is located in the direction of rotation of the spherical disc, and the opposite end surfaces of each arc different roller disposed on one generatrix of the spherical surface of the disc, wherein one end surface of the arcuate rolls positioned along the length of the cutting edges at equal distance from each other is not less than 6 times the width of the weld bead, And the opposite end faces of the arcuate rollers are located at the intersection of the spherical disk surface forming and the auxiliary circle parallel to the cutting edge at a distance from the cutting edge of not more than 0.1 diameter of the spherical disk, the end surfaces of the arcuate rollers on the cutting edge of the concave side of the working surface of the disc are located at half The distances between the end faces of arc-shaped rolls melted on the convex side of the working surface of the disk, lavlennyh ridges on the concave side of 2 times lower than on the convex side of the disc surface.The useful model makes it possible to reduce the wear rate of the working surface of a spherical disk by increasing the loosening intensity and reducing the density of the near-surface contact layer in the zones of the greatest friction intensity with compacted soil when it interacts with the surface of arc-shaped carbide rollers by the thickness of the deposited layer in the direction of travel. 1 yl.Полезная модель относится к сельскохозяйственному машиностроению, в частности к рабочим органам диск
