2K-H行星齿轮减速器传动系统设计

2K-H 行星齿轮减速器（传动系统设计） 【摘 要】 行星齿轮变速器，是用行星齿轮机构实现变速的装置。它通常装在液力变扭器的后面，共同组成液力自动变速器。 行星齿轮机构，有点好像太阳系。它的中央是太阳轮，太阳轮的周围有几个围绕它旋转的行星轮，行星轮之间，有一个共用的行星架。行星轮的外面，有一个大齿圈。行星齿轮变速器，属于一种齿轮箱，它是由行星齿圈、太阳轮、行星轮（又称卫星轮）和齿轮轮轴组成，根据齿圈、太阳轮和行星轮的运动关系，可以实现输入轴与输出轴脱离刚性传动关系、输入轴与输出轴同向或反向传动和输。本文通过对 2K-H 型变速器的传动结构、传动原理及行星齿轮传动的设计来计算一个 2K-H 型变速器。2K-H 型具有构件数量少，传动功率和传动比变化范大，设计容易等优点，因此应用最广泛。论文首先介绍了行星变速器的定义，用途及功能。并对国内外行星变速器的进展现状和进展前景作了分析。通过设计和计算，完成对变速器相关结构的零件设计，整体设计，初步确定了行星变速器结构的总体设计。【关键词】 行星齿轮传动 行星齿轮传动结构 行星齿轮变速器【Abstract】Planetary gear transmission，is the use of planetary gear mechanism of variable-speed device 。 It is usually mounted on the back of the torque converter, consisting of a hydraulic automatic transmission. Planetary gear mechanism, a bit like the solar system. It is the center of the sun wheel, a sun wheel around several of its planets wheel, planet wheel, there is a shared the planet carrier. Planet wheel on the outside, there is a large gear ring. Planetary gear transmission, which belongs to a gear box, which is composed of a planetary ring gear, a sun wheel, a planetary wheel ( also known as satellite wheel and gear wheel shaft ), according to the ring gear, the sun wheel and planetary wheel motor, can achieve the input shaft and the output shaft from the rigid transmission relations, the input shaft and the output shaft the same direction or in the reverse transmission and transmission.This ar...
