摘要

The crank (3) which is mounted on the drive-shaft (2) has a mounting (4) for a pin (5). A bearing housing (6) is fixed on the drive shaft (2) so that it does not turn, and the mounting (4) with the pin (5) is pivot-mounted on the bearing housing (6) by means of an axle (7) and bearings (8). A coupling (9) is fixed onto the pin (5). A universal joint (11) converts the rotary movement from the crank (3) and drive shaft (2) or rocker arm (14) and transmits it to a blade (15). The pin (5) and coupling are joined by a separate bearing (16).
