前言汽车齿轮在使用中损坏的形式与寿命,除取决于齿轮的制造质量外,装配情况,使用条件的工作状况等也起着很要重的作用。齿轮最主要的损坏形式为轮齿折断、齿面点蚀和剥落等。这些都是由于高的接触应力和弯曲应力造成的。我们曾委托长春一汽总成试验室,在 AB58型封闭后桥齿轮试验台上进行弯曲疲劳寿命试验。为进一步探讨轮齿损坏的原因,在西安交大和水电部热工研究所的合作下又作了轮齿的断口检查,弄
Preface The use of car gear in the form of damage and life, in addition to the quality of the gear manufacturing, the assembly, the working conditions of the use of conditions also plays a very important role. The main form of gear damage is broken teeth, tooth pitting and peeling and so on. These are all due to high contact stress and bending stress. We have commissioned Changchun FAW Assembly Laboratory, AB58-type closed rear axle gear test bench for bending fatigue life test. In order to further explore the causes of tooth damage, in Xi’an Jiaotong University and the Ministry of Thermal Engineering, Institute of Thermal Engineering under the cooperation of another made tooth fracture inspection, get
