font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">  < style="background-color: transparent; color: rgb(0, 0, 0); font-family: &quot;宋体&quot;; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">一、查外齿轮 < style="background-color: transparent; color: rgb(0, 0, 0); font-family: &quot;宋体&quot;; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">  < style="background-color: transparent; color: rgb(0, 0, 0); font-family: &quot;宋体&quot;;

white-space: normal; word-spacing: 0px;">1、因齿轮材质(如粉末冶金齿轮)或热处理不好,使齿面磨损严重。如为粉末冶金齿轮,建议改为钢制齿轮,并进行热处理。 < style="background-color: transparent; color: rgb(0, 0, 0); font-family: &quot;宋体&quot;; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">  < style="background-color: transparent; color: rgb(0, 0, 0); font-family: &quot;宋体&quot;; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">渐开线内啮合齿轮泵结构与需修理的主要零件:1——采轴;2、外齿轮;3——泵心组件;4——键;5——薄壁轴承;6——轴承;7——油封;8——螺钉;9——垫圈;10——前盖;l1——后盖;12、13——O形圈。 < style="background-color: transparent; color: rgb(0, 0, 0); font-family: &quot;宋体&quot;; font-size: 16px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: normal; word-spacing: 0px;">  < style="background-color: transparent; color: rgb(0, 0, 0); font-family: &quot;宋体&quot;;

white-space: normal; word-spacing: 0px;"> < style="font-family: &quot;宋体&quot;; font-size: 16px;">2、齿轮端面磨损拉伤。齿轮端面磨损拉伤不严重,可研磨抛光再用;如磨损拉伤严重,可平磨齿轮端面至尺寸h1,外齿圈h2、定子内孔深度h3也应磨去相同尺寸。 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">3、齿顶圆磨损。可刷镀齿轮外圆,补偿磨损量。 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="text-align: center;">1 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;"> < style="font-family: &quot;宋体&quot;; font-size: 16px;">二、查内齿圈 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">1、内齿圈外圆与壳体内孔之间配合间隙太大时,可刷镀内齿圈外圆。 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">2、内齿圈齿面与齿轮齿面之间齿侧隙太大时,有条件的地区(如珠三角、长三角地区),可用线切割机床慢走丝重新加工铜制内齿圈与外齿轮,并经热处理后换上。 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="text-align: center;">1 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;"> < style="font-family: &quot;宋体&quot;; font-size: 16px;">三、查月牙块 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">1、牙块内表面与外齿轮齿顶圆配合间隙太大时,刷镀齿顶圆。 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">2、月牙块内表面磨损拉伤严重,造成压、吸油腔之间内泄漏大时,用线切割机床慢走丝重新加工月牙块换上。 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;"> < style="font-family: &quot;宋体&quot;; font-size: 16px;">四、查壳体(定子)与侧板 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">1、对于兼作配油盘的定子,当配油端面磨损拉有向槽时,如磨损拉伤轻微,可用金相砂布修整再用;如磨损拉伤严重,修复有一定难度。 < style="font-family: &quot;宋体&quot;; font-size: 16px;">  < style="font-family: &quot;宋体&quot;; font-size: 16px;">2、有侧板者,当侧板与齿轮结合面磨损拉伤时,可研磨或平磨侧板端面,并经氮化或磷化处理。
