SUBSTANTIATION OF EFFECT OF TRACTIVE RESISTANCE ON WEAR PARAMETERS OF SWEEP WORKING PARTS
Experimental research of change dynamics of the form of the fret of seeder-cultivator SZS-2.1's working parts was carried out. It is supposed that the angle in question depends on tractive resistance of working part. Through the inclination angle of the reverse chamfer to the shank's blade theoretical calculation of the horizontal component of tractive resistance is presented.
