The invention discloses a planet carrier based on high damping alloy supporting pins and a design method of the supporting pins. The planet carrier comprises a sun wheel input shaft, an inner gear ring supporting frame, a gear ring gear assembly, planet wheel bearings, supporting pins and a planet carrier body. The gear ring gear assembly comprises a sun wheel, planet wheels and an inner gear ring, the planet wheels are arranged between the sun wheel and the inner gear ring and engaged with the sun wheel and the inner gear ring, the inner gear ring is arranged in the inner gear ring supportingframe in a sleeved mode, and the sun wheel is fixed to the sun wheel input shaft. The supporting pins are installed on the planet carrier body, the high damping alloy supporting pins are embedded andfixed in the supporting pins, and the planet wheels are installed on the supporting pins through the planet wheel bearings. The structure design mode that high damping alloy is embedded in the supporting pin of each planet wheel is provided, the uniform load performance of a planet wheel train is improved, and thus the purposes of improving the maximum output power of a system and reducing vibration and noise are realized.
Description
technical field [0001] The invention relates to a planet carrier structure, in particular to a planet carrier structure provided with high-damping alloy support pins and a design method for the high-damping alloy support pins. Background technique [0002] The planetary gear system is mainly composed of several parts such as the sun gear, the input shaft of the sun gear, the ring gear, the planet gear and the planet carrier. The load sharing performance of the entire planetary gear train, that is, the uniformity of the load on each planetary gear is a prominent problem in the planetary gear transmission system. Because it is directly related to the maximum output power, vibration and noise, it is the most important thing to evaluate the planetary gear. One of the important indicators of gear transmission system performance, this problem has not been well resolved so far. [0003] At present, the main means to improve the load sharing performance of the planetary gear system...
