Technical Problem
[0005]本实用新型目的在于提供一种涡轮增压器的封油结构，旨在解决现有涡轮增压器的封油结构存在结构复杂、加工困难以及制造成本高的问题，具体技术方案如下：
Benefits of technology
[0018]本实用新型的封油结构中，所述封油盖与所述装配凹腔在周向形成密封，所述封油盖与转子轴之间形成活动密封，可以有效的防止润滑油泄漏到压气机壳体内部；同时，所述封油盖的内侧设有储油槽，储油槽与挡油板形成一个半封闭的储油腔，通过挡油板上的连接口实现轴承体上的油道与储油腔连通后，既可以存储润滑油又可以实现对封油盖与转子轴之间的相对运动进行润滑。此外，本实用新型在封油盖的周向侧壁设置安装密封圈的安装槽，避免了在装配凹腔内壁开设槽口增加装配凹腔加工复杂程度的问题，以及避免了密封圈安装容易脱落的问题。本实用新型的封油结构具有结构简单，易于加工的优点，能够有效的降低制造成本。
