一种涡轮压裂用减速箱 技术领域
本发明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。
