考慮到平面二次包絡環面蝸桿傳動在多頭小傳動比條件下根切與齒頂變尖的矛盾很難同時解決且嚙合性能較差，介紹了一種新型環面蝸桿傳動? ?球面二次包絡環面蝸桿傳動.在研究過程中，根據工裝建立了坐標系，根據一二包過程的運動關系推得了嚙合方程和蝸桿與蝸輪的齒面方程，分析了蝸輪齒面上的接觸線分佈.為了評價嚙合性能，提出了4項性能指標和5項原始參數，通過大量編程計算得到了嚙合性能指標與原始參數之間的關系，並以圖表直觀的表示Face cone element
齒頂圓錐母線Geometrical design of cylindrical internal involute gear pairs ; diagrams for the determination of addendum modification coefficients
漸開線嚙合圓柱內齒輪副的幾何設計:齒頂高變位系數測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。Collectively, these roofs will create a jagged and twisting silhouette that will be a clear representation of the forces of nature that shape our world
而且，這些屋頂將創造出一個有著鋸齒的、扭曲的天際線，好比自然界的力量般勾勒著我們的世界。For cutting the composite lock gear with unequal tooth thickness, a study is made on the design method of gear sharper cutter with nonstandard parameter involute tooth profile and noninvolute tooth profile. the cutter tooth arrangement, the choice of teeth number of the cutter and the basic method of cutter design are discussed ; and a new method of choosing deflection factor by using limited area is presented. and the curve of relationship between rear angle on tooth crest and helical angle on tooth side of the cutter is given so as to give a basis for the gear sharper cutter to choose its parameters. to design nonstandard gear sharper cutter by adopting the method mentioned above will simplify the calculation and will increase the efficiency of design
