【摘要】 为了获取平面齿内齿轮一次包络鼓形蜗杆传动副(以下简称鼓形蜗杆传动副)的传动性能参数,以鼓形蜗杆传动副的啮合几何学和啮合性能为基础,搭建电封闭式传动性能试验台,对鼓形蜗杆传动副样机在多工况下进行传动性能测试.测试结果为:由于存在制造误差和装配误差,鼓形蜗杆传动副样机的实际接触区为理论接触区的2/3;鼓形蜗杆传动副样机的传动效率随着转速的提高而增加,在低转速时,传动效率随着负载的增大明显降低;在高转速时,传动效率随着负载的增大而略有升高;鼓形蜗杆传动副样机在各测试工况下的最高传动效率为69.05%,最高油池温升为89.8℃;该鼓形蜗杆传动副具有优良的传动性能,适用于重载动力传动.更多还原

【Abstract】 In order to obtain the transmission performance parameters of the planar internal gear primary-enveloping crown worm drive( hereinafter referred to as crown worm drive),an electrically enclosed transmission performance test rig was built based on the meshing geometry and meshing performance to test the transmission performance of a prototype crown worm drive in various working conditions. The test results show that the actual contact areas are only two thirds of the theoretic contact area because of the manufacture error and assembly error. The transmission efficiency of the crown worm drive increases with the rotational speed increasing: as the load increases,the transmission efficiency decreases significantly at low speed,and presents a slight rise at high speed. In various working conditions,the maximum transmission efficiency is 69. 05%,and the maximum temperature rise of box oil is no more than 89. 8 ℃. Therefore,the crown worm drive has an excellent transmission performance,and is suitable for heavy power transmission.更多还原
