国内外使用的分段组合的特大型渐开线圆柱齿轮,都程度不同的存在齿圈段对口开裂问题。即使齿轮加工精度再高,由于对口开裂,也会破坏齿轮啮合性能,影响齿轮使用寿命。本文介绍了笔者研究设计的用“楔型联接螺栓组合的井字对口联接结构”,应用在水泥窑筒体大齿圈上,经过多年运转试验证明,取得了很好的效果。本文还介绍了主要联接零件的设计计算与组合装配方法。这种新型对口联接设计,适用于各种机械的特大型渐开线圆柱齿圈段对口联接的应用。 The segmented combination of large involute spur gears used both at home and abroad have different degrees of cracking of the ring segment counterparts. Even if the gear machining accuracy is high, due to cracking on the counterparts, it will also undermine the gear meshing performance, affecting gear life. In this paper, I study the design with the “wedge coupling bolt combination of Tic-Tac-to-mouth connection structure,” used in cement kiln gear ring gear, after years of running tests proved that achieved good results. This article also describes the design of the main joint parts calculation and assembly assembly method. This new type of counter-coupling design, suitable for a variety of mechanical large involute cylindrical ring segment counterpart connection applications.
