This article describes an investigation that has been conducted to assess the effects of the contact pattern design on the mechanical and thermal behaviors of plastic-steel helical gear drives. The maximum contact pressure, frictional power loss, transmission error function and operating temperature are determined for different designs of the pinion tooth surfaces. Several numerical examples based on loaded tooth contact analyses and steady-state heat transfer analyses are carried out considering different types of micro-geometry modifications of the involute tooth surfaces. The obtained results show that an appropriate design of the pinion tooth surfaces can help reducing the maximum contact pressure and the maximum operating temperature, increasing the durability of the transmission. The frictional power loss and the peak-to-peak transmission error can be diminished, improving the performance of the transmission and increasing its efficiency. Also, it has been shown that the design of the pinion tooth surfaces can provide some capability to the transmission to absorb angular misalignments.

本文介绍了一项调查，该调查旨在评估接触模式设计​​对塑钢斜齿轮传动的机械和热性能的影响。小齿轮齿面的不同设计确定了最大接触压力、摩擦功率损失、传动误差函数和工作温度。考虑到渐开线齿面的不同类型的微观几何修改，基于加载齿接触分析和稳态传热分析的几个数值例子被执行。所得结果表明，适当的小齿轮齿面设计有助于降低最大接触压力和最高工作温度，提高变速器的耐用性。可以减少摩擦功率损失和峰峰值传输误差，从而提高变速器的性能并提高其效率。此外，已经表明小齿轮齿面的设计可以为传动装置提供一些吸收角偏差的能力。
