Abstract

本实用新型涉及一种柴油机部件，尤其是一种适用于R170B型柴油机的柴油机曲轴。该柴油机曲轴具有主轴和曲柄臂，主轴和曲柄臂固定连接，在平行两曲柄臂一端内侧设置有曲柄销，外侧分别设置曲拐，曲柄臂另一端为平衡块，在两曲柄臂内侧增设卸载槽，曲拐为一底部呈锥形上部呈柱形的结构，曲柄臂宽度A为58mm。本实用新型在节约制造材料降低生产成本的同时，有效分散曲轴内部应力，机械性能好。

Description

柴油机曲轴
所属技术领域
本实用新型涉及一种柴油机部件，尤其是一种适用于R170B型柴油机的柴油机曲轴。
背景技术
通常的柴油机曲轴由于曲柄销垂直固定连接于两平行曲柄臂之间，所以在该连接处内应力集中，在柴油机工作过程中该部分承受较大的外力，往往会在该连接处出现裂纹甚至会产生断裂，另外通常柴油机曲柄上的曲拐形状呈锥形，在强度保证的情况下这种结构在生产时比较耗材，使曲轴较为笨重，同时降低的曲轴柔性。
发明内容
本实用新型的目的就在于针对上述现状，通过对曲轴结构的部分改进，旨在提供一种在节约制造材料降低生产成本的同时，有效分散内应力，机械性能好的柴油机曲轴。
本实用新型解决其技术问题所采用的技术方案是：一种柴油机曲轴，具有主轴和曲柄臂，主轴和曲柄臂固定连接，在平行两曲柄臂一端内侧设置有曲柄销，外侧分别设置曲拐，曲柄臂另一端为平衡块，在两曲柄臂内侧增设卸载槽，曲拐一底部呈锥形上部呈柱形的结构，曲柄臂宽度A为58mm。
本实用新型的优点在于：
1.在两曲柄臂内侧增设卸载槽，这样有效分散了曲柄臂与曲柄销连接处的内应力，同时节约了生产成本；
2.在不影响曲轴结构强度的同时，曲拐为一底部呈锥形上部呈柱形的结构，这样最大程度地减轻曲轴重量，节约生产成本，增加了曲轴柔性；
3.加宽曲柄臂，提高了曲轴强度，提高了安全系数。
附图说明
图1是本实用新型的结构示意图。
图2是本实用新型的剖视图。

具体实施方式
下面结合附图和实施例对本实用新型进一步说明。
如图1、图2所示的一种柴油机曲轴，具有主轴1和曲柄臂2，主轴1和曲柄臂2固定连接，在平行两曲柄臂2一端内侧设置有曲柄销3，曲柄臂2另一端为平衡块5，由于在曲柄臂2与曲柄销3连接处应力集中，在柴油机工作过程中该部分承受较大的外力，往往会在该连接处出现裂纹甚至会产生断裂，在曲柄臂2与曲柄销3连接处下方增设卸载槽6，这样有效分散了该处的应力，为了最大程度地减轻曲轴重量，改变原有的锥形曲拐4结构，在保证曲轴强度的同时，对锥形曲拐4继续去重，使曲拐4为底部呈锥形上部呈柱形的结构，为了弥补因开设卸载槽6而降低的机械强度，现将曲柄臂2宽度加宽至56mm，这样提高了曲轴的机械强度。
