[0003] However, when the transmitted power is large, it is necessary to increase the size of each part of the reducer to increase the load strength of the reducer. In this way, the volume of the reducer will inevitably increase, and it cannot be installed in small equipment, which does not meet current requirements. Development trend of equipment miniaturization

The invention discloses a planetary speed reducer. The planetary speed reducer comprises a speed reducer box shell, an input shaft, an output shaft, an input gear, a planetary frame end plate, a plurality of planetary wheel axles, a planetary wheel, an annular gear, a plurality of idle wheels and an idle wheel axle, wherein the input gear is arranged on the input shaft, the planetary frame end plate is rotatably installed on the speed reducer box shell, the planetary wheel axles are fixedly connected with the planetary frame end plate and the output shaft, the planetary wheel is rotatably connected to the planetary wheel axles and is meshed with the input gear, the annular gear is meshed with the planetary wheel, the annular gear is rotatably connected into the speed reducer box shell, the idle wheels are meshed with the annular gear and the output gear of the output shaft, and the idle wheel axle is rotatably connected with the idle wheels and fixed inside the speed reducer box shell. The transmission method of power dividing is adopted in the planetary speed reducer, the power is divided into two paths, the power in one path is transmitted to the output shaft through the input shaft, the planetary wheel, the planetary wheel axle, and the power in the other path is transmitted to the output shaft through the input shaft, the planetary wheel, the annular gear and the idle wheel. Accordingly, the load of the signal part is reduced, and the size of the planetary speed reducer is reduced under the same power condition.
Description
technical field [0001] The invention relates to the technical field of reducers, in particular to a planetary reducer. Background technique [0002] The principle of a planetary reducer is to use a planetary gear mechanism to achieve deceleration. The planetary gear mechanism usually includes a sun gear, a planetary gear, a planetary carrier and a ring gear. The planetary gear is supported by the planetary carrier and revolves around the sun gear. The planetary gear mechanism of the existing planetary reducer uses the sun gear as the active part, and the planet carrier as the passive part, so as to realize power transmission. [0003] However, when the transmitted power is large, it is necessary to increase the size of each part of the reducer to increase the load strength of the reducer. In this way, the volume of the reducer will inevitably increase, and it cannot be installed in small equipment, which does not meet current requirements. The development trend of equipment...
