Description

一种齿轮油泵
技术领域：
本实用新型涉及泵领域，尤其涉及一种齿轮油泵。
背景技术：
齿轮泵是用两个齿轮互啮转动来工作，对介质要求不高。一般的压齿轮油泵力在6MPa以下，流量较大。齿轮油泵在泵体中装有一对回转齿轮，一个主动，一个被动，依靠两齿轮的相互啮合，把泵内的整个工作腔分两个独立的部分。A为吸入腔，B为排出腔。齿轮油泵在运转时主动齿轮带动被动齿轮旋转，当齿轮从啮合到脱开时在吸入侧(A)就形成局部真空，液体被吸入。被吸入的液体充满齿轮的各个齿谷而带到排出侧(B)，齿轮进入啮合时液体被挤出，形成高压液体并经泵排出口排出泵外。
实用新型内容：
本实用新型的目的就是提供一种齿轮油泵，解决现有技术油泵供油不足和齿轮磨损严重的问题。
本实用新型采用的技术方案为：
一种齿轮油泵，包括泵体，其特征在于：泵体前端安装有前盖，前盖通过圆柱销与泵体固定，前盖上设置有进油口，进油口内卡装有孔用弹性挡圈，进油口连接到入油通道，入油通道外套装有骨架油封；泵体内安装有主动轴和从动轴，主动轴上设置有主动齿轮，从动轴上设置有从动齿轮，主动轴外设置有主动轴轴承座组件，从动轴外设置有从动轴轴承座组件；泵体后端通过螺栓安装有后盖，螺栓与后盖之间设置有平垫和轻型弹簧垫圈。
与现有技术相比，本实用新型的有益效果在于：
本实用新型结构简单，安装方便，解决了现有技术油泵供油不足和齿轮磨损严重的问题，降低了齿轮泵工的噪音。
附图说明：
附图1为本实用新型结构示意图。
具体实施方式：
下面结合附图，通过实施例对本实用新型作进一步详细说明：
一种齿轮油泵，包括泵体8，泵体8前端安装有前盖3，前盖3通过圆柱销4与泵体8固定，前盖3上设置有进油口，进油口内卡装有孔用弹性挡圈，进油口连接到入油通道，入油通道外套装有骨架油封2；泵体8内安装有主动轴和从动轴，主动轴13上设置有主动齿轮10，从动轴9上设置有从动齿轮11，主动轴13外设置有主动轴轴承座组件12，从动轴9外设置有从动轴轴承座组件6；泵体8后端通过螺栓7安装有后盖1，所述前盖3与泵体8之间设置有O型密封圈5。
