齿轮传动机构在运转中,由于各种不利因素存在的原因,齿轮会出现各种形式的磨损,轮齿的崩裂是最为严重的损坏现象之一。齿轮的崩裂可采用镶齿法或堆焊法修复。本文通过对DTM250B90低速筒式磨煤机减速器低速齿轮的修复,介绍齿轮崩裂的堆焊和钳工加工方法。
Gear transmission mechanism in operation, due to various unfavorable factors exist, the gear will appear in all forms of wear and tear, gear tooth cracking is one of the most serious damage. Gear cracking can be used to repair tooth or surfacing method. In this paper, DTM250B90 low-speed drum mill gear reducer low speed gear repair, introduced gear cracked surfacing and fitter processing methods.
