JZ21—16机械压力机传动系统的设计.doc

摘要 本课题是对机械压力机传动部分的设计。机械压力机的工作原理是利用曲柄滑块机构，将电机的圆周运动转换成滑块的往复直线运动，从而实现对加工零件的冲压。 对该机械设计时考虑的主要因素是曲柄机构的受力分析和载荷的校核，以及曲轴的发热问题。另外，通过设计飞轮使机械的工作平稳性增强，电机功率得到减小，即满足了设计的要求，又使设计更简单化、合理化。通过二级变速，使电机的高速运动转变为滑块的低速运动，从而使机械的载荷能力大大增强。 根据以上要求设计了机械压力机的传动总图。 关键词 曲柄滑块机构 ；运动及受力分析；传动 Abstract This topic is the design of the mechanical presses transmission. Mechanical press working principle is to use of the slider—crank mechanism to make the electrical machinery that will be conerted into the circular to reciprocating move, thus realizing the spare parts punching. The main factors to consider of the mechanical design is the crank analysis and load the check, and the heat problem of crank. In addition, through the mechanical design of the flywheel is to increase the whole stationeriness, and the electrical power to be reduced, that is designed to meet the rationalization, and it is can make the design more simplifier and rationalizer. Through the secondary transimission , the electrical machinery high-speed move , turn into the slider low-speed movement. So that the mechanical load capacity greatly enhanced. According to the above requirements of the mechanical that design the transmission of transmission assembly drawing Keywords Crank block mechanism Move and stress analysis Transmission 目 录 TOC \o 1-3 \u 掬蚰醮把讵唔煎焦啵梁戮芍 PAGEREF _Toc256000000 \h 氏拆缙簖旭径枘麇崩睥压窨 PAGEREF _Toc256000001 \h 1 绪论榷冷诩錾友房忸叨反跳媳愧 PAGEREF _Toc256000002 \h 0 1.1 我国锻压设备的差距猁聪逯跗侯邱缪渺啵蠊糨冀 PAGEREF _Toc256000003 \h 1 1.2 锻压设备的发展趋势藜挤荛锤蹒谧榇晟阑玻扰衾 PAGEREF _Toc256000004 \h 2 2 概述该荼莞晌柽胪辶拎佥诰徙洛 PAGEREF _Toc256000005 \h 3 2.1 曲柄压力机的工作原理与结构组成惊霈鲠寤路镣镎魄筲肟脯辜 PAGEREF _Toc256000006 \h 3 鏊废擎徨宦钵搠雳鞍吹臧懂 PAGEREF _Toc256000007 \h 5 鸷抡癸锈绰舟昏裒融遮觫脆 PAGEREF _Toc256000008 \h 5 2.2 曲柄压力机的发展概况囿拷轿隙佤婺圳庭免浆葚振 PAGEREF _Toc256000009 \h 5 2.2 通用曲柄压力机的型号和技术参数人嗒詹闲耖笆皮靴蕾矛掖彼 PAGEREF _Toc256000010 \h 7 2.3.1 曲柄压力机的型号狎贾吉苫弘户必欺枇棰驮洼 PAGEREF _Toc256000011 \h 7 2.3.2 通用曲柄压力机的技术参数 瘁互峁毖重槔珞延肉疮巳拖 PAGEREF _Toc256000012 \h 8 潦旯柁控篷供阜攒具髭嗖跑 PAGEREF _Toc256000013 \h
