    • A reverse drive engaging mechanism (12) for a feeder (16) of an agricultural combine (10), including a power unit (56) having an output gear (60) drivingly rotatable by the power unit (56) about an output axis (62), and support structure (72) supporting the power unit (56) and configured to be fixedly mounted proximate to a drive gear (54) of a mechanism to be reversed (14). The support structure (72) supports the power unit (56) such that when the support structure (72) is mounted the output axis (62) will be substantially parallel to a drive axis (64) about which the drive gear (54) is rotatable, and the support structure (72) allows the power unit (56) to be moved substantially linearly in a transverse direction relative to the axes (62, 64) between a disengaged position wherein the output gear (60) is disengaged from the drive gear (54), and an engaged position wherein the output gear (60) is engaged with the drive gear (54). The mechanism (12) includes an actuator (100) controllably operable for linearly moving the power unit (56) at least from the disengaged position to the engaged position, the actuator (100) being operable for initially causing initial rotation of the output gear (60) during the engagement with the drive gear (54), and a mechanism (130) for withdrawing or disengaging the output gear (60) from the drive gear (54) after use.
    • 一种用于农业组合体(10)的进料器(16)的反向驱动接合机构(12),包括具有输出齿轮(60)的动力单元(56),动力单元(56)可通过动力单元(56)围绕输出轴线驱动旋转 支撑结构(72),其支撑动力单元(56),并被配置成固定地安装在靠近要颠倒的机构(14)的驱动齿轮(54)上。 支撑结构(72)支撑动力单元(56),使得当安装支撑结构(72)时,输出轴线(62)将基本上平行于驱动轴线(64),驱动齿轮(54)围绕驱动轴 并且支撑结构(72)允许动力单元(56)在相对于轴线(62,64)的横向方向上基本上线性地移动,在脱离位置之间,其中输出齿轮(60)与驱动器 齿轮(54)和接合位置,其中输出齿轮(60)与驱动齿轮(54)接合。 所述机构(12)包括致动器(100),所述致动器(100)可控地操作用于至少从所述分离位置线性地移动所述动力单元(56)到所述接合位置,所述致动器(100)可操作以初始地引起所述输出齿轮 60),以及用于在使用后从输出齿轮(60)与驱动齿轮(54)取出或分离的机构(130)。
