Abstract

本实用新型公开了一种柴油机气缸套冷却水密封装置,它由气缸套座孔和位于气缸套座孔内的气缸套组成。气缸套座与气缸套的外壁有一个环形的冷却水腔,在气缸套座孔下部与气缸套下定位面对应处有密封槽,密封槽内有密封圈。该装置与密封槽设置在气缸套上的结构相比,提高了气缸套的机械强度,柴油机整机具有重量轻,体积小的优点。

Description

柴油机气缸套冷却水密封装置
本实用新型属于柴油机气缸套冷却水的密封技术。
众所周知,柴油机在工作时会产生大量的热量,为了保证柴油机能正常工作,需要对气缸套进行冷却。水冷式柴油机在气缸套与气缸套座孔之间有一个环形空间——即冷却水腔,在冷却水腔内有冷却水以冷却气缸套和机体。为防止冷却水渗漏,需要对冷却水腔密封。在现有技术中,对水腔下部的密封是在气缸套的下定位面处加工密封槽,将密封圈置于密封槽内,以起到密封冷却水的作用。这样的密封装置存在着以下不足,由于密封槽加工在气缸套上,必然会降低气缸套的机械强度,若要保证气缸套的强度,必须增加缸套的厚度,至使缸套和机体体积增大,重量增加。
本实用新型的目的是提供一种柴油机气缸套冷却水密封装置,可以提高气缸套的机械强度。
本实用新型的目的可通过以下途径得以实现,柴油机气缸套冷却水密封装置包括气缸套和气缸套座孔,气缸套置于气缸套座孔内,气缸套外壁和气缸套座孔之间有一环形的冷却水腔,气缸套座孔上有与外部连接的水道孔,特点是在气缸套座孔下部与气缸套下定位面对应处有密封槽,在密封槽内设置有密封圈。
按上述方案制作的气缸套冷却水密封装置,由于密封槽加工在气缸套座孔上,与现有技术相比,提高了气缸套的机械强度,可以适当增加气缸套的内径,提高柴油机的功率,而且整机体积小,重量轻,维修方便。
下面将结合附图所给出的实施例对本实用新型做进一步的描述。
附图是实施例的结构示意图。
从附图可以看出,实施例由气缸套(1)和气缸套座孔(2)组成,气缸套(1)位于气缸套座孔(2)内,在气缸套(1)和气缸套座孔(2)之间有一个环形的冷却水腔(3),在气缸套座孔(2)下部与气缸套的下定位面(4)对应处有密封槽(5),密封槽(5)内设置有密封圈(6)。气缸套(1)的上端有一凸缘(7),为了保证密封效果,在此凸缘(7)下端面与气缸套座孔(2)上端面的贴合面之间设置有垫子。气缸套座孔(2)上有冷却水流动的水道孔(8)。
