摘　　要：通过对TBD620系列柴油机气缸盖涡流调节机构的适用性研究,从风门工作条件、转轴强度、转轴上应力分布、转轴轴向窜动等方面进行验证,形成了涡流调节机构优化的可行方法。通过该方法优化后的涡流调节机构,可避免柴油机长期在低负荷使用时,风门转轴不停的震动、磨损,最终断裂从而导致拉缸等重大故障的发生。Throughthe adaptive research about the eddy current regulatingmechanism of TBD620 series diesel engine,and to verify from ventilation door work conditions、shaft strength、stress distribution of shaft、axial float of shaft etc,formed the feasible improved method of the eddy current regulating mechanism.The eddy current regulating mechanism which improved by this method,could avoid major failure such as scuffing of cylinder,which caused by shaft of ventilation door continuing shake and wear when diesel engine is often in under load condition.
