齒頂修正系數 -
After thoroughly analyzing the influence of each pump parameters on the gear pump performance, the paper developes the criterion for optimum gear parameters, which can be utilizied in practice easily for gear manufacturing using normal involute gear hob with two - fillet type. the conclutions studied by the paper are : 1. both the addendum coefficient and the deddendum coefficient of the pump gear should be 1. 125
以目前國內普遍使用的雙圓弧頭全齒高為2 . 5倍模數漸開線標準滾刀作為泵齒輪的加工刀具，通過對齒輪加工原理的分析，提出了欲使泵齒輪參數達到最佳，泵齒輪的齒頂高系數和齒根高系數都為1 . 125 ；對變位系數的確定應考慮到泵齒輪的根切、齒頂厚、重合度以及側隙因素；泵齒輪為避免過渡曲線干涉，必然要存在根切現象。 -
Therefore, the suitable coefficient of engagement overlap got by profile correction and addendum modification is beneficial to the output property of the gear pump
因此，對齒輪齒形進行修形和變位修正使齒輪得到合適的嚙合重合系數有利於改善齒輪泵的輸出特性。 -
2. the long - addendum coefficient of pump gear must make the gear in the condition of undercut. base on these conclusions, the basic parameters of pump gear are optimum
