An oil-water separation type anchor rod machine drilling unit based on parallel shaft gear transmission
By employing parallel shaft gear transmission and rotary water seal assembly in the drilling section of the anchor drilling rig, physical isolation between the transmission lubrication chamber and the water flow channel is achieved, solving the oil-water mixing problem caused by downhole seal failure and improving the reliability and operational efficiency of the equipment.

Abstract
本申请实施例提供一种基于平行轴齿轮传动的油水分离式锚杆机钻动部，涉及矿山机械领域。该基于平行轴齿轮传动的油水分离式锚杆机钻动部包括壳体、液压马达、输入轴总成、输出轴总成以及通水系统；所述壳体为金属材质承载基体，内部设有相互平行的轴孔以安装输入轴总成与输出轴总成，壳体内腔形成封闭的润滑油腔；所述液压马达固定连接于壳体端部，其输出端与输入轴总成传动连接以提供动力；输入轴总成与输出轴总成通过齿轮副啮合传动。本方案通过输入主动齿轮轴与输出从动齿轮轴平行轴传动及旋转水封组密封，使传动润滑腔与通水流道完全物理隔离，从根源杜绝油水混合，显著提升轴承、齿轮与密封件寿命，降低故障率与维护成本。
