Description

泥浆泵齿轮轴
所属技术领域
本实用新型涉及钻井作业用的泥浆泵，尤其是涉及泥浆泵动力端的齿轮轴。
背景技术
目前，泥浆泵动力端有一对减速齿轮，包括大齿圈和小齿轮轴。其中的小齿轮轴一般采用整体人字齿轮结构，如图1所示。由于泥浆泵齿轮的工作条件比较恶劣，现有齿轮轴是两端简支的长轴，齿轮位置远离支承轴承，润滑油很难保持无污染，焊接机架的刚性也较差，齿轮轴承受着交变的冲击载荷。因此，齿轮轴齿面接触疲劳破坏--即点蚀现象非常普遍，齿轮轴容易因点蚀使齿面大面积剥落而导致齿轮失效。齿轮轴上的人字齿加工难度很大，需要专用设备加工，生产周期长，增加附加成本。
发明内容
为了克服现有泥浆泵齿轮轴存在的疲劳破坏、加工成本高等不足，本实用新型提供一种泥浆泵齿轮轴。
为了达到上述目的，本实用新型解决其技术问题所采用的技术方案是：传动轴上定位台阶的一侧固定安装有齿轮I、齿轮II；齿轮I和齿轮II为斜齿轮；齿轮I和齿轮II相向安装组合成人字型。齿轮I和齿轮II采用焊接方式固定连接。传动轴上安装有键，键与齿轮I、齿轮II内孔中的键槽配合。
本实用新型泥浆泵齿轮轴的有益效果是，加工难度低，不需专用加工设备，生产周期短，维修方便快速，成本大幅降低。
附图说明
图1是公知泥浆泵齿轮轴结构示意图。
图2是本实用新型泥浆泵齿轮轴结构示意图。
图中：1.传动轴，2.键，3.齿轮I，4.齿轮II，5.定位台阶。
具体实施方式
参照附图，结合附图和实施例对本实用新型作进一步说明。
本实用新型泥浆泵齿轮轴，包括传动轴1，键2，齿轮I3，齿轮II4，传动轴1上定位台阶5的一侧固定安装有齿轮I3、齿轮II4；齿轮I3和齿轮II4为等尺寸的斜齿轮；齿轮I3和齿轮II4相向安装组合成人字型。
齿轮I3和齿轮II4采用焊接方式固定连接。
传动轴1上安装有键2，键2与齿轮I3、齿轮II4内孔中的键槽配合。
齿轮I3、齿轮II4与传动轴1的轴径为过盈配合。
本实用新型泥浆泵齿轮轴的加工难度低，不需专用加工设备，生产周期短，成本大幅降低；一旦齿轮失效，只需更换齿轮I3、齿轮II4，维修方便快速，特别是在批量生产中效果更为显著。
