减速机与工作机的安装关系：为了避免工作机主轴挠曲及在减速机轴承上产生附加力，减速机与工作机之间的距离，在不影响正常的工作的条件下应尽量小，其值为5-10mm。
The relatihip between the reducer and the working machine is: to ***oid the additional force of the spindle and the additional bearing on the reducer bearing, the distance between the reducer and the working machine should be as ***all as sible without affecting the normal working conditi, and its value is 5-10mm.
我们要购买减速机的首要步，首先要确定一点，我们购买的目的。对于减速机的分类，细化开来，有摆线针轮减速机，行星齿轮减速机和蜗轮蜗杆减速机等。还有使用较少的谐波齿轮减速机、滚子凸轮减速机、超环面蜗杆减速机等等。
We want to buy the first step of the reducer, first of all to determine a point, the of our purchase. For the reducer of classification, refined, there are cycloid gear reducer, planetary gear reducer and worm gear reducer and so on. There are also less harmonic gear reducer, roller cam reducer, toroidal worm reducer and so on.
通常齿轮减速机已广泛应用于冶金、矿山、起重、运输、水泥、建筑、化工、纺织、印染、制药、等领域。但在这种齿轮减速机的使用有一定的限制,所以,让我们了解下使用时需要注意什么。
1、高速旋转不超过1500 r / min。齿轮减速器。
2、齿轮圆周速度不超过20 m / s。
Usually gear reducer has been widely used in metallurgy, mining, lifting, transportation, cement, ctruction, chemical, textile, printing and dyeing, pharmaceutical, and other fields. But there are some restricti on the use of this gear reducer, so let us know what to pay attention to when using it.
1. The high speed rotation does not exceed 1500 R / min. Gear reducer.
2, the circumferential speed of the gear is not more than 20 m / S.
降低减速机运转时的齿轮传动噪声已成为行业内的重要研究课题，国内外不少学者都把齿轮传动中轮齿啮合刚度的变化看成是齿轮动载、振动和噪声的主要因素。用修形的方法，使其动载荷及速度波动减至小，以达到降低噪声的目的。这种方法在实践中证明是一种较有效的方法。减速机行业属于国民经济发展的基础行业，从生活家电到汽车飞机、从生产工具到建筑机械，几乎所有的机械传动系统中都需要使用到减速机。
Reducing the gear tran***ission noise of the reducer has become research topic in the industry. Many scholars both at home and abroad regard the change of gear tooth meshing stiffness as the main factor of gear dynamic load, vibration and noise. The method of modification is used to minimize the dynamic load and speed fluctuation in order to reduce noise. This method is proved to be a more effective method in practice.
