提高液压泵寿命的主要途径之一,就是提高它的制造精度,因为几何精度是影响液压泵性能、可靠性及其寿命的主要因素之一。我所在研制WZB—725型斜轴式轴向柱塞泵时,设计了“TG”型镗缸夹具,用来镗缸体(转子)[图1]和主动轴[图2]端面球一也大,最后导致连杆同柱塞破裂等事故,直至泵的毁坏。为确保误差在土5,之内,使主动轴和缸体按转动顺序误差的一致性,而试制此夹具 One of the main ways to improve the life of a hydraulic pump is to improve its manufacturing accuracy because geometric accuracy is one of the major factors that affect the performance, reliability and life expectancy of a hydraulic pump. When we developed WZB-725 inclined axis type axial piston pump, designed “TG” type boring cylinder fixture, used to boring cylinder (rotor) [Figure 1] and the drive shaft [Figure 2] Large, eventually leading to connecting rod with plunger rupture and other accidents, until the pump damage. To ensure that the error in the soil 5, within, so that the drive shaft and the cylinder in accordance with the order of rotation error, and trial production of the fixture
