1 概况在某些回转体零件(如车轮、齿轮等)和圓柱体零件(如轴、辊、销类件)淬火时,有时发生使轮缘、齿圈和轴肩等部位局部及至全部脱(崩)落的碎裂现象,我们分别称为脱缘、脱圈和脱肩,并通称为脱裂.这是人们研究不多的一种淬裂形式,而且,以往的研究或论述也只限于脱肩.应该说尚未彻底搞清楚它的形成原因.本讲将阐述脱裂形成的一般规律性,并在这个基础上来讨论它的产生原因和预防措施.
1 Overview In some parts of the slewing body (such as wheels, gears, etc.) and cylindrical parts (such as shaft, roller, pin type) quenching, sometimes occur such as the rim, ring gear and shoulder parts, such as local and all off Collapse) fall, we are called the detached edge, remove the ring and off the shoulder, and commonly known as the crack. This is one of the less studied form of quenching crack, and the previous study or discussion is limited to It should be said that its cause has not yet been thoroughly elucidated.This talk will explain the general rule of the formation of the crack, and on this basis to discuss its causes and preventive measures.
