摘要：本报告主要研究了盘磨机二级直齿圆柱齿轮减速器的设计方法和具体步骤。在方案设计中说明了设计原理和方法，并进行方案选择，还阐述了所采用方案的特点。对电动机的选择，此报告采用的是三相异步电动机，其结构简单，制造、使用和维护方便，且运行可靠。电动机型号选定后，进行了传动比的计算并进行分配，是否合理的分配传动比将直接影响到传动装置的外廓尺寸、重量、成本以及减速器的中心距等。其后的传动装置的运动和动力参数的计算在计算部分占有一定的比重，各项参数的准确性对整个机器的运行有着很大的影响。在齿轮设计中详细介绍了齿轮材料的选择及许用应力的确定、按齿根弯曲疲劳强度设计计算（因任务书中要求齿轮为展开式）、确定齿轮参数及主要尺寸、确定齿轮传动精度以及齿轮结构的设计，在设计齿轮的具体结构时，要综合考虑多种因素，如齿轮的尺寸、材料、加工方法、热处理等。从动轴的设计在本报告中所占篇幅相对较长，包括轴材料及热处理方法的选择、轴的结构设计以及轴的强度计算。综观整个设计，计算量较大，而数据是否准确将影响减速器的工作效率，因此计算的时候设计者要细心、周到地考虑各种问题。

Abstract:The present report focuses on the two-mill spur gear reducer design and specific steps. In the programme design that the design principles and methods, and options, also described the programme adopted by the characteristics. The motor of choice, this report is based on three-phase asynchronous motor, its structure is simple, manufacture, use and maintenance-friendly, and reliable operation. Motor models selected for the transmission ratio of calculation and distribution, whether or not a reasonable allocation of transmission ratio will directly affect the transmission of the profile, size, weight, cost and reducer such as the center distance. The subsequent transmission of movement and dynamic parameters of the calculation in the calculation of a certain proportion of the possession, the accuracy of the parameters of the whole machinery of running a very great impact. Detailed design of the gear on the gear of choice and determine the allowable stress, fatigue strength of the tooth root bending design and calculation (in the requirements of the mandate for the start-gear), and the main parameters determining gear size, determine the accuracy and Gear The design of gear, the gear in the design of concrete structures, it is necessary to consider a variety of comprehensive factors, such as the size of gear, materials, processing methods, such as heat treatment. Driven shaft design in the present report of the relatively long length, including the shaft materials and heat treatment method of choice, axle shaft and the structural design of the strength calculation. Looking at the whole design, calculation of larger, and the accuracy
