Drive coupler for a reciprocating knife
摘要：
A drive coupler (102, 104) for coupling a reciprocating knife (106) to a drive member (112, 114) is provided, wherein the reciprocating knife (106) includes at least one elongate bar (120, 122, 180, 182) having a longitudinal extent and fixed to a plurality of blades (138), wherein the at least one elongate bar (120, 122, 180, 182) is supported on support members (140) that constrain the at least one elongate bar (120, 122, 180, 182) to reciprocate in a direction generally parallel to the longitudinal extent of the at least one elongate bar (120, 122, 180, 182), the drive coupler (102, 104) comprising: a first elongate strap (146, 162) configured to be attached to the at least one elongate bar (120, 122, 180, 182); a second elongate strap (146, 162) configured to be attached to the at least one elongate bar (120, 122, 180, 182); and an arrangement (152, 164, 187, 189, 193, 200) for (i) flexing the first elongate strap (146, 162) with respect to the second elongate strap (146, 162), (ii) for flexing the first elongate strap (146, 162) with respect to the drive member (112, 114), and (iii) for flexing the second elongate strap (146, 162) with respect to the drive member (112, 114).
摘要（中）：

提供了用于将往复式刀片（106）联接到驱动构件（112,114）的驱动联接器（102,104），其中所述往复式刀具（106）包括至少一个细长杆（120,122,180,182） 具有纵向范围并且固定到多个叶片（138），其中所述至少一个细长杆（120,122,180,182）被支撑在支撑构件（140）上，所述支撑构件限制所述至少一个细长杆 所述驱动联接器（102,104）包括：第一细长带（146,121,180,182），其沿大体上平行于所述至少一个细长杆（120,122,180,182）的纵向延伸的方向往复运动， ，162），其被配置成附接到所述至少一个细长杆（120,122,180,182）; 第二细长带（146,162），其构造成附接到所述至少一个细长杆（120,122,180,182）; 以及用于（i）相对于所述第二细长带（146,162）使所述第一细长带（146,162）弯曲的装置（152,164,187,189,19A，200），（ii）用于使所述第一细长带 相对于驱动构件（112,114）的细长带（146,162），以及（iii）用于相对于驱动构件（112,114）使第二细长带（146,162）弯曲。
