反向齿轮箱体夹具设计 机械设计制造及其自动化 学生： 指导教师： 【摘要】 反向齿轮箱在电机中应用很广泛，在风力发电机组当中就经常用到，而且是一个重要的机械部件。反向齿轮箱体构成的减速器是原动机和工作机之间的独立的闭式传动装置，用来降低转速和增大转矩，以满足工作需要，在某些场合也用来增速，称为增速器。减速器主要由传动零件 齿轮或蜗杆 、轴、轴承、箱体及其附件所组成。箱体是减速器的重要组成部件。它是传动零件的基座，应具有足够的强度和刚度。本文介绍了箱体夹具的计算设计过程。 文章首先介绍了反向齿轮箱的定义和发展情况，然后单独介绍了夹具的意义和设计注意事项。然后根据本课题的研究内容，设计箱体的加工工艺规程和注意事项，最后根据夹具的设计规则设计3号夹具，计算出定位误差，加紧力等确定本夹具的加紧装置，完成夹具设计。然后画出夹具图和箱体装配零件图，完成设计。 【关键词】 反向齿轮 箱体 夹具设计 Reverse gear box fixture design 【Abstract】 Reverse gear box in the motor, in which the wind turbines are often used, but is an important mechanical components. Constitute a reverse gear box reducer is the prime mover and between independent closed gear used to reduce speed and increase torque, in order to meet the needs of the work, is also used in some cases the growth known as the accelerator. Reducer transmission parts gears or worm , shaft, bearings, cabinet and its annex. The box is a key component of the reducer. It is the base of transmission parts, should have sufficient strength and stiffness. This article describes the calculation of the cabinet fixture design process. The article first introduces the definition and development of the reverse gear box, and then separate presentation of the meaning and design considerations of the fixture. Then based on the content of the subject, the design of the cabinet process planning and precautions, and finally on the 3rd fixture designed according to the fixture design rules to calculate the positioning error to step up power to determine the fixture to step up the device, complete the fixture design. Then draw the fixture map and box assembly parts diagram, complete the design. 【Key words】 Reverse gear Box Fixture Design 目录 1. 绪论 2 1.1 选题背景 2 1.2 反向齿轮箱的用途 2 1.3 国内外反向齿轮箱技术状况 2 1.3.1 其次齿轮箱还有如下的作用： 2 1.3.2齿轮箱特点： 3 1.3.3 齿轮箱润滑方式： 3 1.4 反向齿轮箱的发展趋势 3 1.5 设计注意事项 4 1.6 本课题主要设计工作和研究内容 4 2. 夹具的简介 5 2.1 夹具的定义 5 2.2 夹具的分类 5 3. 加工工艺规程设计 6 3.1 工艺规程的内容与作用 6 3.1.1工艺规程是指导生产的技术文件 6 3.1.2工艺规程是生产组织和管理工作的基本依据 6 3.2
