摘要：
FIELD: agriculture machine building.SUBSTANCE: invention relates to agricultural machine building, particularly to tillage tools. Set of soil-cultivating tools contains the basic and model assemblies with constructive arrangements of disk interchangeable tools and separate adjusting units and working parts thereto for installation in unified post-and-frame forced micro-vibration actuators, both with prefabricated disks, and their separate replaceable parts. Basic tool set contains a round flat disk, complete with blade cutters along the its side edge, configured to adjust the angle of attack by holders with cone and splined teeth, contacting in the adjustment bushings welded in on the disk edge. In the disk center the drive square hole is made and around it on the greater circle there are six additional fixing holes, by means of which on the housing with a flange adapter flange a complete interchangeable working disk is fixed. In the driving housing cavity two rolling bearings are installed: one from the right edge – two-row radial with balls in the cage, in which inner or outer bushing is with a smooth round surface, and from the left edge – a thrust bearing with six or less balls or rollers in the cage, tightly seated with a central hole on the axis neck with a key, and the by its head axis is welded in to the vertically located drive post. In the thrust bearing in the two guiding sidewalls, tightly and fixedly held in the housing, two matching raceways for the balls or rollers rolling are made in the inner plane, on the same circumference. In the raceways six or less slides are made through the same interval in a circle and in the gap between them six or less depressions to the calculated working depth of 2.2 mm and a total depth by 3.4 mm. During assembly with fixation relative to the other sidewall by its guide raceway with slides and depressions, one bearing sidewall is turned at an angle of 30° for the possibility between the balls or rollers rolling two side
