Description
本发明属于机械技术领域，涉及一种精密行星齿轮减速机，特别是一种组合式精密行星齿轮减速机。
精密行星齿轮减速机是一种相对精密的传动产品，用于降低转速、传递动力、增大转矩的独立传动部件，在现代机械中应用极为广泛。
目前的精密行星齿轮减速机，有部分应用工况要求精密行星齿轮减速机的输出轴与另一个齿轮减速机组合以便增大减速比和满足安装需求，而普通的齿轮减速机齿轮的啮合中心距完全由齿轮箱的定位安装距定性，由于大模数的齿轮精度等级加工难度非常大，因此在啮合中心距固定的情况下经常出现噪音高、精度不稳定、传动平稳性差等问题。
本发明的目的是针对现有的技术存在上述问题，提出了一种组合式精密行星齿轮减速机，解决的技术问题是如何提高传动精度。
本发明的目的可通过下列技术方案来实现：组合式精密行星齿轮减速机，包括减速机本体和设于减速机本体一侧的减速箱，减速箱包括箱体和均设于箱体内的输入齿轮和输出部件，且输入齿轮通过齿轮传动机构驱动输出部件转动，减速机包括壳体和与壳体转动连接的输出轴，箱体上具有供输出轴一端伸入的开口，且输出轴与输入齿轮固连，其特征在于，上述的壳体包括呈环状的调节部，且调节部位于箱体内，调节部和输出轴同轴线布置，且调节部的外侧壁为圆周面；上述的箱体沿输出轴的径向贯穿设有调节孔，调节孔的孔壁中部设有与圆周面匹配的圆弧口，且圆周面的底部通过圆弧口伸入调节孔；调节孔的两端内均设有调节块，两调节块相邻的一端的顶壁均为相对于调节部向下倾斜设置的斜面，且上述的圆周面抵压在斜面上，两调节孔内还均螺接有螺栓一，螺栓一能推动调节块运动使两调节块相互靠近。
使用过程如下：两螺栓一内旋时分别推动两调节块运动使两调节块相互靠近，此时调节部受斜面挤压上浮，并最终驱动输入齿轮上浮，来提高输入齿轮与齿轮传动机构的啮合中心距；两螺栓一外旋时，两调节块受调节部重量挤压相互远离，使输入齿轮跟随调节部向下浮动，以降低输入齿轮与齿轮传动机构的啮合中心距。
在本减速机中，在斜面、螺栓一等部件的配合下，促使调节部上下浮动，并最终驱动输入齿轮上下浮动以调节输入齿轮和齿轮传动机构的啮合中心距，使输入齿轮和齿轮传动机构精准啮合，来提高整个传动的精度和稳定性。
在上述的组合式精密行星齿轮减速机中，所述的箱体和壳体通过多根螺栓二可拆卸固连。输入齿轮位置调节完毕后，再通过螺栓二锁紧箱体和壳体，使减速箱和减速机本体连为一个整体。
在上述的组合式精密行星齿轮减速机中，所述的箱体在开口处的内壁为环形台阶，且环形台阶和输出轴同轴线布置，上述的调节部位于环形台阶内，该调节部的外径小于环形台阶的内径，且调节部通过密封圈与环形台阶的底壁之间形成密封。实际使用时，壳体和箱体之间的连接依赖上述密封圈实现密封。
在上述的组合式精密行星齿轮减速机中，上述的环形台阶的底壁上设有环形凹槽，上述的密封圈位于环形凹槽内，且密封圈的两端面分别与环形凹槽的底壁和调节部的端面相抵。
在上述的组合式精密行星齿轮减速机中，上述的齿轮传动机构为设于输入齿轮一侧的大齿轮，大齿轮与箱体转动连接，且大齿轮与输入齿轮相啮合，上述的输出部件呈筒状，输出部件的内端插设在大齿轮内，且输出部件和大齿轮相固连，输出部件由弹性材料制成，输出部件的内端外侧壁为锥面一，大齿轮的内侧壁上具有与锥面一匹配的锥面二，且锥面一和锥面二紧密贴靠，所述的输出部件的侧壁上还设有沿该输出部件的轴向贯穿设置的缺口。安装时，用户设备输入轴插在输出部件内，当输出部件往大齿轮内部运动时，在锥面一和锥面二的配合下使输出部件向内收缩抱紧用户设备输入轴，使输出部件内壁和用户设备输入轴侧壁紧密贴靠无间隙产生，来有效提高整个传动的精度和稳定性，使本减速机适合在长期频繁正反转或启停的恶劣环境中工作。
在上述的组合式精密行星齿轮减速机中，所述的输出部件的外端外壁上具有环形翻边，且上述的缺口延伸至环形翻边，环形翻边沿输出部件的轴向贯穿设有螺丝孔，螺丝孔有多个并沿输出部件的周向均布，大齿轮上设有螺纹孔，螺纹孔和螺丝孔数量相同且位置一一正对，大齿轮和输出部件通过穿过螺丝孔并旋于螺纹孔内的螺丝相固连。采用上述的设计，方便用户设备输入轴的拆装。
在上述的组合式精密行星齿轮减速机中，上述的大齿轮的两端面上均一体成型有呈环状的连接部，连接部和大齿轮同轴线布置，且两连接部均通过轴承与箱体转动连接。
与现有技术相比，本组合式精密行星齿轮减速机具有以下优点：
、在斜面、螺栓一等部件的配合下，促使调节部上下浮动，并最终驱动输入齿轮上下浮动以调节输入齿轮和齿轮传动机构的啮合中心距，使输入齿轮和齿轮传动机构精准啮合，来提高整个传动的精度和稳定性。
、调节部既用于实现调节输入齿轮和齿轮传动机构的啮合中心距，又实现壳体和箱体之间的密封连接，使调节部具备一物两用的效果，在简化结构的同时，又方便组装。
、在锥面一和锥面二的配合下使输出部件抱紧用户设备输入轴，使输出部件内壁和用户设备输入轴之间无间隙产生，来有效提高整个传动的精度和稳定性，使本减速机适合在长期频繁正反转或启停的恶劣环境中工作。
