自升式平台升降传动装置
摘要：
本实用新型涉及一种钻井平台的动力组件，特别涉及一种自升式平台升降传动装置，它包括：承载体，所述的承载体内设爬升主齿轮，爬升主齿轮连接在主传动轴上，主传动轴的一端连接主传动齿轮，主传动齿轮啮合从传动齿轮，从传动齿轮连接在从动轴上，从动轴的一端连接二级传动齿轮，二级传动齿轮啮合二级从传动齿轮，二级从传动齿轮连接三级传动轴，三级传动轴连接平行轴减速箱，从传动齿轮位于主传动齿轮的外侧。其体积较小、自重较低，大大提高了平台本身的承载能力。
摘要（英）：

The utility model relates to a drilling platform power component, especially relates to a self-lifting type platform elevating transmission device, which comprise a bearing body; an elevating main gear is disposed in the bearing body; the elevating main gear is connected on a driving shaft; one end of the driving shaft is connected with a driving gear; the driving gear is engaged with a driven gear; the driven gear is connected on a driven shaft; one end of the driven shaft is connected with a secondary driving gear; the secondary driving gear is engaged with a secondary driven gear; the secondary driven gear is connected with a third driving shaft; the third driving shaft is connected with a parallel axes reduction box; and the driven gear is located at on the outside of the driving gear. The device has the advantages of small volume and light weight, improves the bearing capacity of the platform greatly.
