Because of its irregular shape, installation complexity, low-yield, high processing costs, expensive equipment. Proposed special equipment vibration polishing machine polishing. Polishing is an ultra-precision machining processing method, the advantage of high precision machining and processing a wide range of materials. The polishing machine is embedded abrasive lap on the workpiece surface grinding tool, is an important condition to ensure that the abrasive machining. Traditional grinding low processing efficiency, processing costs, unstable machining precision and quality shortcomings, which makes traditional grinding application subject to certain restrictions, in order to improve the efficiency of grinding, mechanical polishing machine has replaced the traditional hand-grinding. This paper is reasonable analysis of vibration polishing machines the drivetrain and polishing principle, the vibration polishing machine design by the motor, deceleration device, vibration motor, vibration disk, and the design of the deceleration device. In order to have a sufficient rigidity, strength and stability of the main parts of the worm gear reducer school life. 【Key word】Crankshaft; vibration polishing; worm 目 錄 摘 要 I Abstract II 目 錄 III 第1章 緒論 1 1.1本課題的研究背景及意義 1 1.2振動(dòng)研磨機(jī)國(guó)內(nèi)外發(fā)展現(xiàn)狀 3 1.3本課題研究?jī)?nèi)容 5 第2章 振動(dòng)拋光機(jī)研究 6 2.1振動(dòng)研磨機(jī)的工作原理 6 2.2振動(dòng)研磨的運(yùn)動(dòng)機(jī)理 8 第3章 蝸輪蝸桿減速器設(shè)計(jì) 10 3.1電動(dòng)機(jī)的選擇 10 3.2傳動(dòng)零件的設(shè)計(jì)計(jì)算 12 3.3 軸的設(shè)計(jì) 16 第4章 軸承的選擇和計(jì)算 21 4.1渦輪軸的軸承的選擇和計(jì)算 21 4.2 減速器鑄造箱體的主要結(jié)構(gòu)尺寸 22 第5章 其他零件設(shè)計(jì) 24 5.1鍵連接的選擇和強(qiáng)度校核 24 5.2 聯(lián)軸器的選擇和計(jì)算 24 5.3 減速器的潤(rùn)滑 25 致 謝 26 參考文獻(xiàn) 27 III
