Abstract

本实用新型是一种改进的柴油机铸铁湿式缸套,其特点是缸的内径公称尺寸为100毫米,外形为阶梯形,与缸体装配处尺寸同95系列缸套,缸套壁厚仅5毫米,其上的阻水圈槽多而浅。这种缸套可装配在现有95系列柴油机缸体上、但可配装100系列活塞,使柴油机气缸增容,因而重量既轻,又能提高柴油机功率。

Description

柴油机簿壁增容湿式缸套
本实用新型涉及内燃机缸体配件,特别是一种柴油机铸铁湿式缸套。
现有柴油机的缸体上均镶有与活塞相配的缸套,这样不仅制造、维修方便,而且可以延长缸体的使用寿命。缸套内径公称尺为95毫米的95系列柴油机,如195、295、495、695柴油机是现今保有量最大的柴油机。这类柴油机普通存在重量大、油耗高,动力性较差的缺点,能否利用柴油机原有缸体,而对缸套等进行改造,从而提高这类柴油机的动力性能呢?
本实用新型的目的就是要提供一种能装配在原95系列柴油机缸体上、却能配用外径公称尺寸为100毫米的活塞的铸铁湿式缸套,使原95系列柴油机增容,提高功率的柴油机缸套。
为完成发明目的而设计的柴油机铸铁湿式缸套,内径公称尺寸为100毫米,缸套的外形为阶梯形,与缸体装配处尺寸同95系列缸套,缸套的壁厚为5毫米,其上的阻水圈槽为三道,槽深2毫米、槽宽2.5毫米。
本实用新型薄壁增容湿式缸套与缸体配合处的装配尺寸与现有195柴油机缸套相同,因而可方便地装入现有95系列柴油机的缸体,由于其壁薄,使内径公称尺寸扩大到100毫米,因而可配用裙部直径为100毫米的活塞,三道阻水槽又提高了阻水性能,再加上对气缸垫、阻水圈、活塞、活塞环、活塞肖、柱塞、喷油嘴和涡流室镶块等配件作了相应的改动和选择,就增大了柴油机气缸的容量及排量、增幅达10%,从而提高了有效功率。测试结果表明,换用本实用新型薄壁增容铸铁湿式缸套的195柴油机的功率出8.8千瓦能提高到11千瓦。而理论计算和改装实践都证明,5毫米壁厚的气缸套在使用中是安全可靠的。所以本实用新型薄壁气缸套可以节省原材料及能源,能减轻柴油机重量,提高动力性能。
以下结合附图描述本实用新型。
图1是本实用新型实施例薄壁增容铸铁湿式缸套示意图。
如图1所示,缸套的外形为阶梯形,即头部4外径公称尺寸为118毫米,水套上止口5外径公称尺寸为111毫米,水套部6外径公称尺寸为110毫米,阻水圈上部及下部外径又略小于水套部6。阻水圈沟槽2较现有缸套多一道,有三道,且较浅,提高了阻水性能。
