目前,对齿轮磨损后的修复方法已有不少论述,但对于在60年代问世并在磨机中广泛应用的大变位齿轮却很少涉及。本文在对大变位齿轮磨损后所可能采用的修复方法进行分析比较之后,认为采用大压力角渐开线齿轮可以综合提高齿轮的承载能力。无论弯曲强度、接触强度和在抗胶合耐磨能力上,大压力角齿轮都比20°压力角齿轮优越。所以,近年来,大压力角齿轮在国外已得到广泛地应用。
At present, there have been many discussions on the repair methods of gear wear, but little is said about the large gear changes that came out in the 1960s and are widely used in mills. After analyzing and comparing the repair methods that may be used after gear wear of large displacement gear, this paper considers that the use of large pressure angle involute gear can improve the bearing capacity of gear. Regardless of flexural strength, contact strength and wear resistance in the anti-gluing, large pressure angle gear than 20 ° pressure angle gear superiority. Therefore, in recent years, large pressure angle gear has been widely used abroad.
