平衡轴支撑结构
相关申请的交叉引用
本申请要求于2019年11月28日向韩国知识产权局提交的申请号为10-2019-0155814的韩国专利申请的优先权和权益,该韩国专利申请的全部内容通过引用并入本文。
技术领域
本公开涉及一种平衡轴支撑结构。更具体地,本公开涉及一种减弱由动态行为引起的振动的平衡轴支撑结构。
背景技术
在发动机开发中,由于客户的需求不仅扩展到基本的发动机耐久性和动力性能,而且还扩展到NVH性能,因此诸如噪声/振动的抑制性能以及耐久性和动力性能是重要的因素。
平衡轴与曲轴一起是发动机最重要的振动源之一。滚针轴承应用于一般的平衡轴,并且因此平衡轴的振动可直接传递到气缸体。
由于空间限制,设置在发动机内部的平衡轴被制造为细长形状,这可能导致由于径向变形引起的振动而产生嘎嘎的冲击声。气缸体的振动会通过激发气缸体的裙部(薄壁区域)和油底壳而引起噪声。
为了提高发动机的静音性,吸声和隔音材料可以被应用于产生噪声的部件,例如缸体和油底壳,但是这会导致成本/重量增加。
在该背景技术部分中公开的以上信息仅用于增强对本公开背景的理解,因此,其可能包含不构成本领域普通技术人员在该国已知的现有技术的信息。

平衡轴支撑结构可以进一步包括在导向衬套的一端处形成的衬套凸缘,以通过支撑辊部的一端来防止辊部脱离。
平衡轴可以包括在径向方向上突出的轴凸缘,并且轴凸缘可以支撑辊部的另一端。
橡胶减震器可以通过硫化粘合剂而固定到平衡轴轴颈。
平衡轴支撑结构可以进一步包括插设在橡胶减震器和平衡轴轴颈之间的基底衬套。
基底衬套可以被压入到平衡轴轴颈。
根据本公开的示例性实施例的平衡轴支撑结构可以包括:外部衬套,与气缸体联接;辊部,设置在外部衬套内侧,并且包括辊和辊保持架;导向衬套,设置在辊部的内侧,以支撑辊部的旋转并限制辊部的轴向移动;以及橡胶减震器,插设在导向衬套和平衡轴轴颈之间以防止平衡轴的振动传递。
平衡轴支撑结构可以进一步包括在导向衬套的一端处形成并支撑辊部的一端的衬套凸缘。
平衡轴可以包括在径向方向上突出的轴凸缘,并且轴凸缘可以支撑辊部的另一端。
橡胶减震器可以通过硫化粘合剂而固定到平衡轴轴颈。

附图说明
图1是根据本公开的示例性实施例的平衡轴支撑结构的分解透视图。
图2是根据本公开的示例性实施例的平衡轴支撑结构的剖视图。
图3是根据本公开的变形的示例性实施例的平衡轴支撑结构的剖视图。
具体实施例
在下面的详细描述中,仅通过说明的方式示出和描述了本公开的某些示例性实施例。
如本领域技术人员将认识到的,可以以各种不同的方式修改所描述的实施例,而所有这些都不脱离本公开的思想或范围。
在整个说明书中,用相同的附图标记表示的组件表示相同的组件。
在附图中,为了清楚起见,放大了层、膜、板、区域等的厚度。
当层、膜、区域、板等的组件被描述为在另一组件“上”时,这不仅包括该组件直接在另一组件上,而且还包括其他组件介于该组件与另一组件之间的情况。
相反,当一个组件被描述为“直接在”另一组件“上”时,则表示在一个组件与另一组件之间不存在其他组件。
在整个说明书和权利要求书中,除非有相反的明确描述,否则词语“包括”和诸如“具有”或“包含”的变体将被理解为暗示包括所述组件,但不排除任何其它组件。
以下将参照附图详细描述本公开的示例性实施例。
图1是根据本公开的示例性实施例的平衡轴支撑结构的分解透视图,图2是根据本公开的示例性实施例的平衡轴支撑结构的剖视图。
参照图1和图2,根据本公开的示例性实施例的平衡轴支撑结构可以包括:轴承部30,与气缸体10联接;以及橡胶减震器50,插设在轴承部30和平衡轴轴颈72之间以防止平衡轴70的振动传递。
轴承部30可以包括:外部衬套32,与气缸体10联接;导向衬套34,设置在外部衬套32的内侧;以及辊部40,插设在外部衬套32和导向衬套34之间,并且包括辊42和辊保持架(roller cage)44。
平衡轴支撑结构可以进一步包括在导向衬套34的一端处形成的衬套凸缘36,以通过支撑辊部40的一端来防止辊部40脱离。
换言之,根据本公开的示例性实施例的平衡轴支撑结构,外部衬套32联接到气缸体10,外部衬套32内侧设置有包括辊42和辊保持架44的辊部40,并且支撑辊部40的旋转并限制辊部40的轴向移动的导向衬套34设置在辊部40内侧。橡胶减震器50插设在导向衬套34和平衡轴轴颈72之间,以防止平衡轴70的振动传递。
平衡轴70可以包括在径向方向上突出的轴凸缘74,并且轴凸缘74可以支撑辊部40的另一端。因此,辊部40的轴向移动由衬套凸缘36和轴凸缘74限制。
平衡轴支撑结构可以进一步包括插设在橡胶减震器50和平衡轴轴颈72之间的基底衬套80。
基底衬套80可以被压入(press fitting)到平衡轴轴颈72。即,导向衬套34、橡胶减震器50和基底衬套80的组件可以通过基底衬套80的压入被固定到平衡轴70。
图3是根据本公开的变形的示例性实施例的平衡轴支撑结构的剖视图。
在说明图3所示的根据本公开的变形实施例的平衡轴支撑结构时,对于与根据图1和图2所示的本公开的实施例的平衡轴支撑结构相同的构造,使用相同的附图标记,并且省略重复的描述。
如图3所示的根据本公开的变形实施例的平衡轴支撑结构可以包括弹性地支撑轴承部30的橡胶减震器51,并且橡胶减震器51可以通过硫化粘合剂而固定到平衡轴轴颈72。
橡胶减震器51被硫化粘合到平衡轴轴颈72,从而减少了部件数量。
根据本公开的一个或多个示例性实施例的平衡轴支撑结构可以通过减小平衡轴的振动幅度和对平衡轴缓冲来减小传递到气缸体的振动。
另外,应用硫化型橡胶形状可以在相同形状的情况下增加橡胶体积,从而进一步降低强度并提高隔振性能。
根据本公开的一个或多个示例性实施例的平衡轴支撑结构,可以通过减少安装在发动机外侧的吸声和隔音材料来减少NVH和成本。
尽管结合当前被认为是实用的示例性实施例描述了本公开,但是应当理解的是,本公开不限于所公开的实施例。相反,本公开旨在涵盖所附权利要求书的思想和范围内所包括的各种修改和等同布置。
