Description

异型曲柄对置式柴油内燃机
一、技术领域、本发明异型曲柄对置式柴油内燃机，尚属四冲程内燃机系列领 P域。
二、背景技术、目前国内外四冲程内燃机曲柄旋转两周完成一个工作循环，而异型曲柄四冲程对置式内燃机，主轴旋转一周，对置两缸各完成一个工作循环，尚属领先地位。
三、发明内容、本发明技术由：主轴、异型曲柄、大滚轮、滚道轨、直杆活塞、缸套、缸盖及配气机构、对开缸体、轴承盘座、轴承(111000型)、紧定衬套、内外轴承盖。由异型曲柄传动机构及大滚轮驱动对置活塞左右往返运动。主轴、异型曲柄、大滚轮组成成一个独立体(A)，滚道轨与左右直杆活塞组成一个独立体(B)；独立体(A)的大滚轮装配到独立体(B)的滚道轨的接触面上，呈微隙配合。主轴嵌装着半圆键与异型曲柄为固配合，为增加主轴的抗弯强度，中间设置数道COOPER剖分轴承支撑。对开缸体将左右两侧活塞固定在往返运动的轨道上，对开缸体接触面两侧对角各安装一个定位销定位，螺丝紧固。直杆活塞与滚道轨由30°的齿槽吻合链接和定位销定位，螺丝紧固(见图3)。
主轴穿过缸体两侧加工的圆孔(轴承盘座内装有111000型轴承由内外轴承盖紧固，使轴承定位)将全套轴承盘座，套在主轴两侧各由六条对丝固定在两侧缸壁上，内轴承盖卡槽装有扁头螺栓，防止螺栓转动，卡槽末端穿有开口销，防止螺栓脱出(见图4)。打开外轴承盖，(将大滚轮中心线对准滚道轨中心线)将紧定衬套螺母锁紧，装上油密封
轴承盖，螺丝紧固。也可采取常规式轴瓦结构，对开缸体的一侧缸体设有数道轴瓦支架，其中有一道翻边止推瓦(参考康明斯止推瓦结构)由轴瓦盖将主轴固定在对开缸体的一侧缸体上，主轴端装有阻油封。
四、附图说明
图1、异型曲柄内燃机示意图。
图2、异型曲柄内燃机旋转90°俯视图。
图3、直杆活塞与滚道轨连接示意图。
图4、轴承盘座及内外轴承盖示意图。
图5、滚轮滚道轨迹实施参考图升成99mm。
图6、滚轮滚道轨迹实施参考图升程140mm。
图7、内燃机滚轮滚道轨迹实施参考图升程140mm。
注：图5图6图7采用靠模优选法绘制而成，通过动画验证符合理想要求，通过模型试验运转通常。

实施例一
图中主轴1、异型曲柄2、大滚轮(内装轴承)3、滚道轨4、直杆活塞5、缸套6、缸盖7、轴承盘座8、内外轴承盖9、轴承10、紧定承套11、对开缸体12
可做成1、2、3、4、5、6、8对缸内燃机，设：六对缸haoshi内燃机，以0°、30°、60°、90°、120°、150°的位置上各有一对缸做功，主轴旋转一周，共有12个缸均布连续做功。四对缸haoshi内燃机，以0°、45°、90°、135°的位置上各有一对缸做功，主轴旋转一周，共有8个缸均布连续做功。
柴油内燃机匹配增压器有两种方式，(1)排气涡轮增压，(2)主轴前端设置一个大涡轮供各缸增压。
实施例二
多对缸内燃机，一侧所有缸数同时并列做功(这是内燃机的一大特点)。即X对缸内燃机，一侧X缸数同时并列做功，主轴旋转一周共有2X缸在做功。
例：2对缸机(一左一右为一对缸)，左侧两个缸同时并列做功，
主轴旋转一周共有四个缸在做功，
同理，3对缸机主轴旋转一周，共有6个缸在做功。
设：6对缸内燃机(实施例一) 升程140mm
缸径选择100-135mm 转速选择2000-2200r/min
功率可达1000数百ps。
这样的小机型大功率柴油内燃机可用于货轮、舰艇、坦克上。
