摘要

为改善斜齿轮传动误差的载荷特性,提出了一种层合材料齿轮。齿轮有三层,其中金属具有不同的刚度层压在齿宽方向。两边的层由相同的金属制成,中间层使用不同的金属。通过理论分析,探讨了高低刚度层的布置和中心层宽度的变化对复合材料的影响。层合齿轮具有不同于传统均质材料齿轮传动误差的载荷特性。通过高刚性中心层与低刚性侧层的组合可以减小传动误差,通过适当调整中心层宽度可以在较宽的负载范围内保持较低的传动误差。减小传动误差的原理是,通过改变与层合材料单节距啮合过程的刚度,使齿的弹性变形在很大程度上抵消了齿面形状在大载荷范围内引起的转动波动。制造了一对层压齿轮,试验证实,层压齿轮的传动误差低于均质材料齿轮的传动误差。与均匀齿轮相比,层压齿轮具有在更宽的负载范围内实现更低振动/噪音产生的潜力。

Basic study on transmission error for gear made from different metals laminated in width direction to provide rigidity distribution
To improve the load characteristics of the transmission error for helical gears, a gear made of laminated materials is proposed. The gear has three layers in which metals with different rigidities are laminated in the tooth width direction. The layers on both sides are made from the same metal, and a different metal is used for the central layer. A theoretical analysis was performed to investigate the effects of arranging high- and low-rigidity layers and changing the width of the central layer. The laminated gear has load characteristics different from the transmission error for a conventional homogeneous material gear. The transmission error can be reduced with the combination of a high-rigidity central layer and a low-rigidity side layers, and a low transmission error can be maintained over a wide load range by adjusting the central layer width appropriately. The principle of the reduction in the transmission error is that, by changing the rigidity along one-pitch meshing progress with laminated materials, the elastic deformation of the teeth can largely cancel out the rotational fluctuations caused by the tooth flank shape over the wide load range. A pair of laminated gears was manufactured, and testing confirmed that the laminated gear has a transmission error lower than that for a gear made from a homogeneous material. The laminated gear has the potential to achieve the lower vibration/noise generation for the wider load range than the homogeneous gear.
