以一对双压力角非对称渐开线直齿减速齿轮机构为研究对象,在考虑齿面摩擦的情况下,通过对轮齿的单双齿啮合情况进行受力分析,建立齿轮支座反力的数学模型,并给出了任意齿间载荷系数下齿轮支座反力波动程度的评价指标.研究表明:齿面摩擦是导致齿轮支座反力波动的影响因素之一;可通过提高齿面加工精度,合理润滑,减小压力角及适当增大驱动轮的齿数等措施来降低齿轮支座反力的波动.
Taking a pair of asymmetric involute gear reducer with double pressure angle as the research object, under the condition of considering the friction of the tooth surface, the force analysis of single tooth and double tooth meshing was carried out to establish the counterforce , And gives the evaluation index of reaction force fluctuating degree of gear support under any interdental load coefficient.The research shows that the friction of tooth surface is one of the influencing factors of reaction force fluctuation of gear support, Processing accuracy, reasonable lubrication, reduce the pressure angle and the appropriate increase in the number of drive wheel teeth and other measures to reduce the gear bearing reaction force fluctuations.
