Description

一种喷油泵齿轮结构
技术领域
    本实用新型涉及齿轮领域,具体为一种喷油泵齿轮结构。 
背景技术
    喷油泵是汽车柴油机的一个重要组成部分,用于向汽车气缸喷射柴油。喷油泵中动作部件上安装有齿轮作为运动传递零部件,现有技术喷油泵齿轮重量较重,且与齿轮轴结合不紧密。 
实用新型内容
本实用新型目的是提供一种喷油泵齿轮结构,以解决现有技术喷油泵齿轮重量较重,与齿轮轴结合不紧密的问题。 
为了达到上述目的,本实用新型所采用的技术方案为: 
一种喷油泵齿轮结构,包括有轮盘,轮盘盘缘上设置有轮齿,其特征在于:轮盘前盘面中间位置设置有凸台,从凸台向轮盘后盘面开有四级依次扩径的锥形通孔,所述轮盘前盘面上还开有多个减重槽。
所述的一种喷油泵齿轮结构,其特征在于:所述减重槽均匀分布在凸台周围。 
本实用新型结构简单,易于实现,通过设置的减重槽能降低轮盘的重量,同时利用多级锥形通孔可提高与齿轮轴之间紧配程度,进而提高了齿轮运转稳定性。 
附图说明
    图1为本实用新型的结构示意图。 
具体实施方式
如图1所示。一种喷油泵齿轮结构,包括有轮盘1,轮盘1盘缘上设置有轮齿,轮盘1前盘面中间位置设置有凸台2,从凸台2向轮盘1后盘面开有四级依次扩径的锥形通孔3、4、5、6,轮盘1前盘面上还开有多个减重槽7,减重槽7均匀分布在凸台2周围。 

Claims (2)
