SYSTEM TO PROVIDE CONNECTION BETWEEN A DRIVING MECHANISM OF MOWER KNIFE AND MOWER KNIFE

摘要

A system to provide a connection between a driving mechanism of a mower knife and the mower knife 1 which makes linear reciprocal movements 1 includes the first metal connecting element 4 which either forms a mount assembly with the mower knife 1 or serves for connecting therewith, at least partially is made as a ring and has a round cylindrical through opening 6 which forms a longitudinal axis 5, has a cut and is equipped with stretching means 11 for changing a transversal cut of the through opening metal intermediate ring 14 which has the round cylindrical outer surface 19 which corresponds to the through opening 6, has the internal surface 18 shaped as a hollow ball. It is received into the through opening 6 by outer surface 18 thereof 6, on circle thereof has at least one cut, a rotary rolling bearing which has a metal outer bearing ring 20 with the spherical surface 21 closed in the circle direction which corresponds to the internal surface 18 of the intermediate ring 14 and is surrounded with the intermediate ring 14 and also forms at least one outer roller path 22. It has at least one metal internal bearing ring 23, closed in the circular direction which forms at least one roller path of an internal ring 24 and which has a through setting opening 26, has a rolling body 25 arranged between the outer roller path 22 and the roller path of the internal end 24, the second connecting element 27 which comprises a leading finger 29 set into the setting opening 26.
