成都理工大学毕业设计（论文）PAGE 成都理工大学毕业设计（论文）（宋体五号居中）保护轻载传动的转矩限制器【摘要】当过载时,轻载传动将失败,有八种装置可以使得轻载传动远离危险的转矩载荷。本设计旨在设计一款具有轻载传动的保护功能的螺旋输送机，通过八种转矩限制器方案对比，选择一种最优方案作为螺旋输送机的转矩限制器。对转矩限制器进行分析设计，设计中采用了动力学分析计算和零件材料的强度校核。论文详细论述了螺旋输送机的功能设计、结构设计、运动和受力分析、材料选用和校核等。采用转矩限制器就是为了防止螺旋输送器在过载的时候烧坏电机。保证了设备的安全和可靠性。【关键词】保护；轻载传动；转矩限制器；螺旋输送器； （插入分节符，本节插入页码时，选择首页不显示页码）Protection of light-load driving torque limiterName：×××Student No.： ××××Major： ××××（××××）Supervisor： ×××Abstract: When overload, light load drive will fail, there are eight devices can make the light-load driving torque load away from danger. This is designed to protect the design of a light-load transmission function CNC grinding plant cutting oil grinder Screw, by contrast eight torque limiter scheme, choose an optimal scheme as the torque limit screw conveyor device. Analysis and design of the torque limiter, the design uses a strength check calculation and dynamic analysis of parts and materials. Paper discusses in detail the functional design of the screw conveyor, structural design, motion and stress analysis, material selection and verification and so on. Using the torque limiter is to prevent the screw conveyor when burn out the motor overload. Ensure the safety and reliability of the equipment.Key words: Protection; light-load driving; torque limiter; screw conveyor;（插入分节符，本节插入页码时，选择首页不显示页PAGE 1目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc419539694 第1章 前言 PAGEREF _Toc419539694 \h 1 HYPERLINK \l _Toc419539695 1.1选题背景及其意义 PAGEREF _Toc419539695 \h 1 HYPERLINK \l _Toc419539696 1.2研究现状 PAGEREF _Toc419539696 \h 1 HYPERLINK \l _Toc419539697 1.2.1永磁体结构 PAGEREF _Toc419539697 \h 1 HYPERLINK \l _Toc419539698 1.2.2臂支撑滚子结构 PAGEREF _Toc419539698 \h 2 HYPERLINK \l _Toc419539699 1.2.3锥形离合器结构 PAGEREF _Toc419539699 \h 3 HYPERLINK \l _Toc419539700 1.2.4带和销轴结构 PAGEREF _Toc419539700 \h 4 HYPERLINK \l _Toc419539701 1.2.5箱体弹簧结构 PAGEREF _Toc419539701 \h 5 HYPERLINK \l _Toc419539702 1.2.6圆环滚子结构 PAGEREF _Toc419539702 \h 5 HYPERLINK \l _Toc419539703 1.2.7
