减速器的种类繁多，按照传动类型可分为齿轮减速器、蜗杆减速器和行星齿轮减速器；按照传动级数不同可分为单级和多级减速器；按照齿轮形状可分为圆柱齿轮减速器、圆锥齿轮减速器和圆锥－圆柱齿轮减速器；按照传动的布置形式又可分为展开式、分流式和同轴式减速器。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。
There are many types of reducer according to tran***ission type can be divided into gear reducer, worm reducer and planetary gear reducer; according to tran***ission series can be divided into single and multi-stage gear reducer; according to the shape can be divided into cylindrical gear reducer, bevel gear reducer and cone - cylindrical gear reducer; according to the arrangement the form of tran***ission can be divided into expansion, split and coaxial reducer.

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。所有紧力螺栓均需用力矩板手按标明的固定扭力矩数据进行固定和检查。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。
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 tran***ission 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).
