Gear transmission mechanism

The utility model discloses a gear transmission mechanism, including output shaft and output shaft, fixed mounting the first gear of input shaft and fixed mounting at the second gear of output shaft, be equipped with the idler gear between first gear and the second gear. The utility model provides a gear transmission mechanism through using gear drive replacement belt transmission, can reduce diesel engine's power loss effectively, and the wearing and tearing volume of part among the transmission structure reduces the maintenance cost, avoids the skid appearance of phenomenon of transmission simultaneously, and transmitting movement is accurate reliable, has improved driven stationarity. 本实用新型公开了种齿轮传动机构，包括输出轴以及输出轴，固定安装在输入轴的第齿轮以及固定安装在输出轴的第二齿轮，第齿轮与第二齿轮之间设有惰齿轮。本实用新型提供的齿轮传动机构，通过使用齿轮传动替换皮带传动，可有效地可以减少柴油发动机的动力损耗，传动结构中零件的磨损量，降低维护成本，同时避免传动打滑现象的出现，传递运动准确可靠，提高了传动的平稳性。
