变位齿轮在齿轮泵中的应用

Application of Shift Gear in the Gear Pump

变位齿轮应用于齿轮泵有很多优点:能够配凑中心距,能使机构结构紧凑,适当的负变位使排量增大,正变位使齿根强度增大。对大型齿轮泵进行维修时,可用齿轮变位修复轮齿磨损,节约维修费用,缩短维修工期。

Application of shift gear in the gear pump has many advantages： center distance can be fitted,structure size can be compacted.The appropriate negative shift can increase displacement,positive shift can increase tooth root strength.For maintenance of large gear,tooth wear can be repaired by shift gear,and maintenance cost is reduced,maintenance period is shorterd.
