Description
技术领域
本实用新型涉及涡轮压裂技术领域，具体涉及一种涡轮压裂用减速箱。
背景技术
目前车载的涡轮压裂设备，动力源是涡轮发动机，传动装置是减速箱和传动轴或者联轴器，执行元件是压裂柱塞泵。涡轮发动机本身具有体积小、重量轻、功率密度大的优势，同样的外形尺寸和重量，涡轮压裂设备的单机功率是常规柴油机压裂设备的2倍以上。涡轮发动机可以直接100％以天然气为燃料，不像电驱压裂设备，不需要燃气发电的中间环节，省却了燃气发电机组的投资成本，同时，采用涡轮压裂设备可以把单台大功率燃气发电机的故障风险均摊到每台涡轮压裂设备上，避免了单台燃气发电设备故障导致全套压裂车组瘫痪的风险。
安装在涡轮压裂设备中的行星齿轮减速箱，由于空间小，常采用悬臂整体式结构，但如果对行星架支撑处理不当，可能导致行星架刚度降低，振动增大，齿轮啮合件的不均匀现象加强，从而大大降低行星齿轮传动的可靠性和寿命。
为此亟待一种方便安装，整体结构紧凑，传动性能好的涡轮压裂用减速箱。
实用新型内容
本实用新型的目的克服现有技术的不足，提供一种涡轮压裂用减速箱，本减速箱整体结构紧凑、体积小、重量轻、传动比大，动力由太阳轮轴小端齿轮输入，经太阳轮轴大端齿轮和行星轮啮合降速增扭，通过行星架输出。利用行星轮组的结构减小齿轮尺寸和数量，更适用于涡轮发动机减速要求。打开盖板通过观察孔，可以起到维保方便的作用。刹车装置与刹车片的配合使用，如遇紧急情况可立即使设备停止运行，保护设备及人身安全。
本实用新型的目的是通过以下技术措施达到的：一种涡轮压裂用减速箱，所述减速箱包括太阳轮轴，行星轮和轴承，所述行星轮为3个，所述轴承为6个，行星轮与轴承一对二套接后形成3组行星轮组，太阳轮轴包括大端齿轮和小端齿轮，3组所述行星轮组以大端齿轮为圆心分布在其周围，并且行星轮与大端齿轮啮合连接。
进一步地，3组所述行星轮组以大端齿轮为圆心均匀分布在其周围。
进一步地，所述大端齿轮包括第一大端齿轮和第二大端齿轮，第一大端齿轮为右旋斜齿，第二大端齿轮为左旋斜齿。
进一步地，所述行星轮包括第一轮齿面和第二轮齿面，所述第一轮齿面为左旋斜齿，第二轮齿面为右旋斜齿。
进一步地，所述第一大端齿轮与第一轮齿面啮合连接，第二大端齿轮与第二轮齿面啮合连接。
进一步地，所述减速箱包括输入轴承，法兰，内齿圈和行星架，所述法兰与内齿圈连接，所述法兰内设输入轴承，所述输入轴承套设在太阳轮轴上，所述内齿圈与行星轮组的行星轮啮合连接，所述行星架通过销轴与轴承连接。
进一步地，所述减速箱包括输出花键轴和输出花键轴套，所述输出花键轴的一端与输出花键轴套连接，输出花键轴的另一端与行星架连接。
进一步地，所述减速箱包括上箱体、下箱体和输出销轴，所述上箱体与下箱体连接组成减速箱外部的保护箱体，在保护箱体的一侧与法兰连接，在保护箱体的另一侧通过输出销轴与输出花键轴连接。

进一步地，所述上箱体上设有刹车装置，在输出花键轴套上设有刹车片，所述刹车装置与刹车片配合使用。
与现有技术相比，本实用新型的有益效果是：本减速箱整体结构紧凑、体积小、重量轻、传动比大，动力由太阳轮轴小端齿轮输入，经太阳轮轴大端齿轮和行星轮啮合降速增扭，通过行星架输出。利用行星轮组的结构减小齿轮尺寸和数量，更适用于涡轮发动机减速要求。打开盖板通过观察孔，可以起到维保方便的作用。刹车装置与刹车片的配合使用，如遇紧急情况可立即使设备停止运行，保护设备及人身安全。行星轮与太阳轮之间采用双排人字形齿轮啮合的结构，增加接触面积，减小对齿轮的垂直压力，有利于润滑油的流动，消除了斜齿轮轴上的横向力，使齿轮重合度高，轴向载荷小，承载能力高，工作更加平稳。
