MOTION CONVERTER AND DRIVE UNIT COMPRISING A MOTION CONVERTER

motion converter (5A, 5B, 5C, 5D, 8C) structured for converting a rotational motion provided by a motor shaft (31A, 31B, 31D, 3) into a linear reciprocating motion of a drive shaft (70A, 70B, 70D). The motion converter (5A, 5B, 5C, 5D, 8C) has a deformable unit (50A, 50B, 50C, 50D, 8C), a mounting unit (60A, 60B, 60D) connected with the deformable unit (50A, 50B, 50C, 50D, 8C), a coupling unit (59A, 59B, 59C, 59D, 8A) connected with the deformable unit (50A, 50B, 50C, 50D, 8C), the coupling unit (59A, 59B, 59C, 59D, 8A) being structured to receive the drive shaft (70A, 70B, 70D) or the coupling unit (59A, 59B, 59C, 59D, 8A) comprising the drive shaft (70A, 70B, 70D), a connector unit (8A, 8B, 8C, 8D) connected with the deformable unit (50A, 50B, 50C, 50D, 8C), the connector unit (8A, 8B, 8C, 8D) comprising at least a first essentially U-shaped receiver (90E) being structured for receiving a first eccentric shaft element (41A, 41B, 41D) of the motor shaft (31A, 31B, 31D, 3) and having a U-base and two U-legs together defining a first elongated hole (804B, 805B, 814B, 902E) having a length (1), a width and a height, and a first bracing element (903E) that connects the two U-legs of the first essentially U-shaped receiver (90E) on their free ends such that access into the first elongated hole (804B, 805B, 814B, 902E) across the width and the height of the first elongated hole (804B, 805B, 814B, 902E) is provided, preferably where the first bracing element (903E) is bar-shaped or U-shaped or O-shaped, and where the length (1) is measured from an inner surface of the U-base to the free ends of the U-legs.
