内行星

According to introduction, they make use of Europe south the astronomical observatory establish in 3.6 meters caliber astronomical telescope of the Chile a set of the mountain lodge of 2400 meters saddle type of an elevation, confirm Be located on south the fixed star"Gliese 581" inside the along while ball scales horoscope see toward the speed because it surroundings can't see fixed star of gravitation function but"perturbation" for appear, subsequently reckon this a red and short star neighborhood of"new the Earth" round a mother fixed star of revolution around sun period and quality.

根据行星的介绍，他们利用欧洲南方使用建立天文台3.6米口径的智利一集的山2400米的海拔马鞍型，提出确认将于南部的恒星"格里斯581"所在的内沿，同时对球尺度占星速度见的天文望远镜因为它周围看不到固定的引力作用，但"摄动出现，随后估计这是一个红色的和短期的"新地球"轮明星邻居母亲围绕太阳固定期限和质量革命之星"的明星。

It is made up of amoderate breeze gear wheel transmission that the MG400/920-WD typemining machine cuts the cutting department, cut the electricalmachinery of cutting department and put to fix up horizontally inthe rocker arm, the power that the motor outputs leans on a roundof transmission of department of gear wheel and planet round viathe tertiary straight tooth, urge the cylinder to rotate finally.

MG400/920-WD 型采煤机截割部主要是由四级齿轮传动组成，截割部电机放在摇臂内横向布置，电动机输出的动力经由三级直齿圆柱齿轮和一级行星轮系的传动，最后驱动滚筒旋转。

This design firstly fixed ondesign scheme and selected basic components, and besides, developedthe reliability analysis of transmission system. The design ofMG300/701-WD Shearer's cutting unit. It is made up of a gearbox andmoderate breeze gear wheel transmission that the MG300/701-WD typemining machine cuts the cutting department, Cut the electricalmachinery of cutting department and put to fix up horizontally inthe rocker arm, The power that the motor outputs leans on a roundof transmission of department of gear wheel and planet round viathe tertiary straight tooth, Urge the cylinder to rotate finally.

本文首先确定了设计方案和选择了基本部件并开展了传动系统的可靠性分析，MG300/701-WD型采煤机截割部主要是由一个减速箱和四级齿轮传动组成，截割部电机放在摇臂内横向布置，电动机输出的动力经由三级直齿圆拄齿轮和行星轮系的传动，最后驱动滚筒旋转。
