Description

轴承润滑装置及工程机械 本申请要求于 2012 年 8 月 14 日提交中国专利局、 申请号为 201220402275.4 、 发明名称为"轴承润滑装置及工程机械"的中国专利申请 的优先权， 其全部内容通过引用结合在本申请。 技术领域
本实用新型涉及工程机械领域， 特别涉及一种轴承润滑装置及设置有 该轴承润滑装置的工程机械。 背景技术
在各种工程机械中， 对于压路机来说， 振动轴承的润滑尤其重要。 振 动轴承是用来支撑振动压力机的激振装置的， 激振装置的激振力大、 转速 高， 因此如果轴承润滑不良很容易导致轴承温度过高， 进而引起烧死、 磨 损、 早期失效等故障。 现在压路机的润滑方式一般采飞溅润滑或依靠滚轮 存储润滑油， 然后使润滑油流入到滚轮侧壁上， 再由侧壁流入到轴承座， 从而对轴承起到润滑和散热作用。 但是由于设计缺陷， 当滚轮转动很小的 角度（小于 90度） 时， 润滑油就会从轴承座的侧壁流下来， 无法保证润滑 油能够流入油孔， 因而导致轴承内端面的一侧润滑不足， 容易引起轴承发 热， 造成轴 7?磨损。 发明内容
有鉴于此， 本实用新型旨在提出一种轴承润滑装置及具有该润滑装置 的工程机械， 以使润滑油能够快速充分的对轴承进行润滑。
为达到上述目的， 本实用新型的技术方案是这样实现的：
一种轴承润滑装置， 包括轴承座， 在该轴承座上设有用于安装轴承的 安装位， 在所述轴承座的侧壁上还设有储油斗、 集油槽和导油孔， 所述储 油斗设置在所述安装位的周围， 所述集油槽为设置在所述储油斗与所述安 装位之间的环形槽状结构， 且所述储油斗与所述集油槽连通， 所述导油孔 为连通所述集油槽与所述轴 7|内端面的孔。
进一步的， 所述储油斗为多个相互独立的条形槽状结构， 在所述储油 斗上覆盖有环形板状的封油板， 在所述封油板上设有与所述储油斗对应的 进油孔。
进一步的， 所述储油斗为焊接在所述轴承座的侧壁上的盒状结构， 在 所述盒状结构靠近所述集油槽的一面设有出油孔。
进一步的， 所述储油斗至少有三个且呈环形均勾分布在所述安装位周 围。
进一步的， 所述封油板通过螺釘连接在所述轴承座上。
进一步的， 所述进油孔的直径小于所述储油斗最窄处的宽度。
进一步的， 所述导油孔与所述储油斗——对应。
一种工程机械， 设置有如上所述的轴承润滑装置。
进一步的， 所述工程机械为压路机。
相对于现有技术， 本实用新型具有以下优势： 本实用型新所述的轴承 润滑装置设有用于封盖储油斗的封油板， 可以将从进油口流入储油斗的润 滑油封存在储油斗内， 进而使滚轮在转动时， 储油斗内的润滑油能够通过 导油孔流到轴承内端面， 这样不仅可以使轴承得到充分的润滑和散热， 还 可沖走轴承内圏剥落的铁屑， 起到清洁作用。 附图说明
构成本实用新型的一部分的附图用来提供对本实用新型的进一步理 解， 本实用新型的示意性实施例及其说明用于解释本实用新型， 并不构成 对本实用新型的不当限定。 在附图中： 图 1为本实用型新所述的轴承润滑装置的结构示意图；
图 2为图 1中 A-A向剖视图；
图 3为本实用型新所述轴承安装座的结构示意图；
图 4为本实用型新所述封油板的结构示意图。
附图标记说明：
1-轴承座， 11-储油斗， 12-集油槽， 13-导油孔， 2-轴承， 21-轴承内端 面， 22-安装位， 3-封油板， 31-进油孔， 4-螺釘。 具体实施方式 需要说明的是， 在不沖突的情况下， 本实用新型中的实施例及实施例 中的特征可以相互组合。 下面将参考附图并结合实施例来详细说明本实用 新型。
图 1至图 4即为本实用型新实施例的相关附图， 如图中所示， 本实施 例为一种轴承润滑装置， 主要包括轴承座 1和封油板 3, 在该轴承座 1上设 有用于安装轴承 2的安装位 22, 在轴承座 1的侧壁上还设有储油斗 11、 集 油槽 12和导油孔 13 ,储油斗 11为设置在安装位 22周围的相互独立的条形 槽状结构， 用于存储流进来的润滑油， 为加强对轴承的润滑效果， 在本实 施例中， 一共在安装位 22周围设置了六个储油斗 11 , 这六个储油斗 11呈 环形均匀的分布在轴承位四周。 集油槽 12为设置在储油斗 11与安装位 22 之间的环形槽状结构， 且储油斗 11与集油槽 12连通， 导油孔 13为连通集 油槽 12与轴 内端面 21的孔， 导油孔 13与储油斗 11——对应且导油孔 13的数量与储油斗 11的数量一致。封油板 3为通过螺釘 4覆盖连接在储油 斗 11上的环形板状结构，在封油板 3上设有与储油斗 11对应的进油孔 31 , 进油孔 31的直径小于所述储油斗 11最窄处的宽度， 以免从进油口流入储 油斗 11内的润滑油流出来。
作为上述方案的其他实施方式， 储油斗还可以为焊接在轴承座 1 侧壁 上的盒状结构， 该盒装结构靠近集油槽 12的一面设有出油孔， 该盒装结构 内的润滑油可以通过该出油孔经轴 7|座 1的侧壁流入导油孔 13。
除了上述的轴承润滑装置， 本实用新型还提供一种设置有上轴承润滑 装置的工程机械， 特别是一种设有上述轴承润滑装置的压路机， 该压路机 的其它各部分的结构参考现有技术， 本文不再赘述。
当上述的轴承润滑装置应用于压路机的振动轴承时， 其润滑原理是这 样的： 滚轮转动时， 轴承座随之转动， 此时润滑油会从封油板的进油口流 入轴承座上最下端的储油斗， 该储油斗会随着滚轮的转动而逐渐由下端转 动到上端， 而由于有封油板的存在， 所以储油斗内的润滑油只能通过集油 槽流入导油孔内进而流入振动轴承的内端面， 对轴承进行润滑、 散热， 并 沖走轴承内圏剥落的铁屑。
以上所述仅为本实用新型的较佳实施例而已， 并不用以限制本实用新 型， 凡在本实用新型的精神和原则之内， 所作的任何修改、 等同替换、 改 进等， 均应包含在本实用新型的保护范围之内。
工业实用性
本实用新型提供的轴承润滑装置设有用于封盖储油斗的封油板， 可以 将从进油口流入储油斗的润滑油封存在储油斗内， 进而使滚轮在转动时， 储油斗内的润滑油能够通过导油孔流到轴承内端面， 这样不仅可以使轴承 得到充分的润滑和散热， 还可沖走轴承内圏剥落的铁屑， 起到清洁作用。 因此， 本实用新型具有工业实用性。
