齿轮减速机具有体积小，传递扭矩大的特点。齿轮减速机在模块组合体系基础上设计制造，有的电机组合、安装形式和结构方案，传动比分级细密，满足不同的使用工况，实现机电一体化。

Gear reducer has the characteristics of small volume and large torque transmission. Gear reducer is designed and manufactured on the basis of modular combination system. There are very many motor combinati, installation forms and structural schemes. The transmission ratio is fine and classified to meet working conditi and achieve mechanical and electrical integration.

减速机是国民经济诸多领域的机械传动装置，行业涉及的产品类别包括了各类齿轮减速机、行星齿轮减速机及蜗杆减速机，也包括了各种专用传动装置，如增速装置、调速装置、以及包括柔性传动装置在内的各类复合传动装置等。

The reducer is a mechanical drive device in many fields of national economy, industry related product categories include all kinds of gear reducer, planetary gear reducer and the worm reducer, also includes a variety of special transmission device, such as accelerating device, device, and a flexible transmission device, transmission device, including various types of composite.

减速机作为机械传动的组成部分，其重要意义不言而喻。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。随着市场需求的不断深化，让减速机市场得到快速发展，当然减速机的品种也在不断丰富。当选用斜齿轮减速机时有以下几点需要注意：允许输入轴径：减速机的输入轴孔与电机输出轴一般是通过一个厚度可以变化的套环来连接的。

As an important part of mechanical transmission, the speed reducer is self-evident. The reducer industry is the basic industry of national economic development, from living appliances to automobile aircraft, from production tools to ctruction machinery, almost all of the mechanical transmission systems need to be used to the reducer. With the deepening of market demand, the reducer market has been developing rapidly. Of course, the variety of reducer is also continuously enriched.

齿轮声辐射特征分析 在选择用不同结构形式的齿轮时，对其特定结构建立声辐射模型，进行动力学分析，对齿轮传动系统噪声进行预先评估。以便根据使用者的不同要求（使用场所，是 否无人操作，是否在城区内，地上、地下建筑物有无特定要求，是否有噪声防护，或无其他特定要求）去满足。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。

The acoustic radiation characteristic analysis of gear in the selection of gear with different structure forms, set up the acoustic radiation model to its specific structure, carry on the dynamic analysis, and evaluate the gear transmission system noise in advance. In order to meet the users'  requirements (use sites, unmanned operati, whether there are specific requirements in the urban area, ground or underground buildings, noise protection, or other specific requirements).
