基于标称齿轮当量载荷的聚合物齿轮齿面承载能力评价方法
An Evaluation Method for Tooth Surface Load Capacity of Polymer Gears Based on Nominal Gear Equivalent Load
摘要
Abstract
The current evaluation methods for the tooth surface load capacity of polymer gears still rely on the methods for metal gears,which did not comprehensively consider the influences of material type,lubrication condition and stress of the polymer gears.This would lead to significant re-liance on engineering experience for material selection,strength design and loading capacity evaluation in practical engineering applications.Therefore,a polymer gear tooth surface load capacity evaluation method was proposed based on the nominal gear equivalent load.Over 169 sets of data and more than 6000 hours of durability tests on polymer gears were obtained,considering different lubrication condi-tions,gear materials,and machining methods.The results show that oil lubrication may significantly improve the tooth surface load capacity of plastic gears,and the tooth surface load capacity of PEEK(polyether ether ketone)gears is more than 30%higher than that of POM(polyoxymethylene)and PA66(polyamide)gears under oil lubrication,which provides an evaluation method and basic data support for active design and transmission power applications of polymer gears.关键词
