二级齿轮传动模块包括输出轴 9和传动轴 10， 输出轴 9上设有输出齿轮组， 传动轴 10上设有与输出齿轮组啮合的传动齿轮组， 输出齿轮组和传动齿轮的其 中之一与其转轴转动配合，其中之一与其转轴同步转动， 与齿轮转动配合的输出 轴或传动轴上设有用于接合转轴与齿轮组的离合器 II 11。
输出齿轮组包括与输出轴 9转动配合的两个输出齿轮， 分别为输出齿轮 12 和输出齿轮 13， 输出齿轮 12和输出齿轮 13均通过轴承套装在输出轴 9上， 实 现与输出轴 9之间的转动配合。传动齿轮组包括与输出齿轮组一一对应并相互啮 合的两个传动齿轮， 分别为传动齿轮 14和传动齿轮 15， 传动齿轮 14和传动齿 轮 15均固定设置在传动轴 10上， 实现与传动轴 10同步转动，传动齿轮 14与输 出齿轮 12啮合， 传动齿轮 15与输出齿轮 13啮合。
离合器 II 11设置在输出轴 9上并位于输出齿轮 12和输出齿轮 13之间； 离 合器 II 11上设有齿圈 16， 输出齿轮 12和输出齿轮 13面向离合器 II 11的一 侧均设有用于与齿圈 16啮合的外齿。
离合器 II 11有三个位置状态： 分别与输出齿轮 12或输出齿轮 13啮合， 使 得输出齿轮 12或输出齿轮 13与输出轴 9接合并驱动输出轴 9转动， 当离合器 II 11位于输出齿轮 12和输出齿轮 13之间时， 不与输出齿轮 12和输出齿轮 13 啮合， 此时输出齿轮 12和输出齿轮 13空转。
本实施例的传动齿轮组与过渡齿轮组啮合，且过渡齿轮组和传动齿轮组中分 别只有一个齿轮相互啮合， 具体的为传动齿轮 15和过渡齿轮 7啮合， 使得二级 齿轮传动模块在一级齿轮传动模块带动下转动。
本实施例的输出轴 9和传动轴 10分别向两对轧机辊组输出动力， 即为一轴 输入两轴输出， 且输出轴 9和传动轴 10的转动方向相反。
本实施例用于高速轧机的齿轮变速装置呈上下两层结构，即一级齿轮传动模 块和二级齿轮传动模块呈上下两层布置，一级齿轮传动模块位于上层， 二级齿轮 传动模块位于下层，采用该结构的齿轮变速装置结构更加紧凑， 能够满足轧机之 间布置紧凑的要求。
本实施例用于高速轧机的齿轮变速装置的一级齿轮传动模块通过离合器 I 3 主动齿轮组或过渡齿轮组选择性的与其转轴接合， 可组合出多条传动路线， 从而 得到不同的传动比； 二级齿轮传动模块通过离合器 II 11控制输出齿轮组或传动 齿轮组选择性的与其转轴接合，也可组合出多条传动路线，并得到不同的传动比， 本实施例用于高速轧机的齿轮变速装置的两级齿轮传动模块组合具有四种传动 路线， 即可得到四种不同的传动比。 通过输出轴 9和传动轴 10—起向轧机辊组 输出动力， 构成一输入两输出的齿轮变速系统。通过将一级齿轮传动模块和二级 齿轮传动模块设置为上下两层布置， 结构更加紧凑，满足了轧机之间布置紧凑的 要求。且本实施例用于高速轧机的齿轮变速装置还具有结构简单、离合器的数量 少、 传动的可靠性高、 维护容易、 制造和使用成本低的优点。
第二实施例
如图 3所示，本发明用于高速轧机的齿轮变速装置第二实施例的上层结构示 意图； 图 4为本实施例的下层结构示意图。
本实施例用于高速轧机的齿轮变速装置将输入轴 1置于上层，过渡轴 2与二 级齿轮传动模块一起位于下层， 使得齿轮变速装置的重心更低， 工作更稳定。
本实施例的其他结构与第一实施例相同， 不再一一累述。
第三实施例
如图 5所示，为本发明用于高速轧机的齿轮变速装置第三实施例的上层结构 示意图； 图 6为本实施例的下层结构示意图。
本实施例用于高速轧机的齿轮变速装置还包括输出轴 II 17， 输出轴 II 17 上设有与其同步转动的从动齿轮 18， 从动齿轮 18与传动齿轮组啮合， 具体的为 从动齿轮 18和传动齿轮 15啮合， 输出轴 9和输出轴 II 17分别向两对轧机辊组 输出动力。 本实施例的传动轴 10不再向轧机辊组输出动力， 由于输出轴 9上的 输出齿轮组和输出轴 II 17上的从动齿轮 18均与传动齿轮组啮合， 因此， 输出 轴 9和输出轴 II 17的转向相同。
本实施例的其他结构与第一实施例相同， 不再一一累述。
上述实施例中虽然均是主动齿轮组和输入轴 1转动配合、输出齿轮组与输出 轴 9转动配合的技术方案，但是需要指出的是： 也可以采用过渡齿轮组与过渡轴 2转动配合、 主动齿轮组和输入轴 1同步转动的技术方案； 或采用传动齿轮组与 传动轴 10转动配合、 输出齿轮组与输出轴 9同步转动的技术方案。 采用这些技 术方案的齿轮变速装置与上述实施方式相当， 不再一一累述。
下面介绍采用多台本发明用于高速轧机的齿轮变速装置组合得到的多输入 多输出齿轮变速传动系统的实施方式。
如图 7所示，为采用上述第二实施例和第三实施例的齿轮变速装置组合得到 的多输入多输出齿轮变速传动系统的上层结构示意图；图 8为多输入多输出齿轮 变速传动系统的下层结构示意图。 多输入多输出齿轮变速传动系统包括至少两台上述用于高速轧机的齿轮变 速装置，如图 7所示，该多输入多输出齿轮变速传动系统包括两个齿轮变速装置， 其中一个齿轮变速装置的结构与上述第二实施例相同， 为一轴输入两轴输出， 且 两输出轴的转动方向相反； 另一个齿轮变速装置的结构与上述第三实施例相同， 为一轴输入两轴输出， 且两输出轴的转动方向相同。 由于用于高速轧机的齿轮变 速装置的结构紧凑， 能够满足轧机之间布置紧凑的要求。
由于齿轮变速装置具有两根输出轴， 可驱动连续的两台轧机， 使连续的两 台轧机之间通过齿轮变速装置传动形成多组速比关系，且相邻的两台轧机由一个 电机驱动，在保证了两台轧机之间的布置距离较近的情况下， 电机可以容易的布 置得下。
同理， 两个这样的齿轮变速装置可驱动连续的四台轧机， 且四台轧机之间的 距离由于不受电机布置尺寸的限制，可以布置更紧凑。两两轧机之间的速比关系， 可通过调节离合器位置来调节齿轮变速装置的转速比和通过变频调节电机的转 速， 实现无级的速比组合关系，使得其中两架轧机和另外两架轧机间的速比调节 关系具有大的柔性和使用灵活性。
当然，多输入多输出齿轮变速传动系统可采用任意两台或两台以上的齿轮变 速装置组合得到。
最后说明的是， 以上实施例仅用以说明本发明的技术方案而非限制，尽管参 照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解， 可以 对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和 范围， 其均应涵盖在本发明的权利要求范围当中。
