摘要: 本課題是棘輪手動(dòng)壓力機(jī)的設(shè)計(jì)，針對(duì)機(jī)械裝置工作條件，設(shè)計(jì)符合實(shí)際工作要求的壓力機(jī)。壓力機(jī)的設(shè)計(jì)包括齒輪軸、齒條、箱體的設(shè)計(jì)和一些零部件的選用校核等。在設(shè)計(jì)過(guò)程中，根據(jù)任務(wù)書(shū)提供的壓力機(jī)的長(zhǎng)度、寬度、高度、行程等要求，完成壓力機(jī)的總體設(shè)計(jì)。其中主要以人力為主，通過(guò)齒輪帶動(dòng)齒條運(yùn)動(dòng)，用棘輪實(shí)現(xiàn)自鎖，用手輪回復(fù)齒條，其中主要設(shè)計(jì)了各個(gè)系統(tǒng)傳動(dòng)的零部件，結(jié)構(gòu)比較簡(jiǎn)單，屬于典型的手動(dòng)壓力機(jī)
對(duì)壓力機(jī)進(jìn)行受力分析，完成齒輪的設(shè)計(jì)。由于壓力機(jī)的機(jī)身結(jié)構(gòu)緊湊，齒輪與軸連成一體，做成齒輪軸結(jié)構(gòu)。在齒輪軸設(shè)計(jì)時(shí)候，完成選用軸承、擬定軸上的零件的裝配方案、校核軸的強(qiáng)度要求等工作。完成齒輪軸結(jié)構(gòu)的的設(shè)計(jì)后，就可以進(jìn)一步確定與其嚙合的齒條的尺寸，并設(shè)計(jì)齒條的工藝規(guī)程。齒條的工藝規(guī)程設(shè)計(jì)有兩種方案，比較兩種方案的優(yōu)劣，選擇合適的一種。軸承對(duì)壓力機(jī)的工作發(fā)揮著重要的作用，應(yīng)該校核其強(qiáng)度，設(shè)計(jì)其密封裝置等。在以上各項(xiàng)工作完成后，可以設(shè)計(jì)壓力機(jī)機(jī)身（箱體）的設(shè)計(jì)和軸承端蓋的設(shè)計(jì)。最后，還應(yīng)進(jìn)行成本校核，成本核算的實(shí)質(zhì)是一種數(shù)據(jù)信息處理加工的轉(zhuǎn)換過(guò)程，即將日常已發(fā)生的各種資金的耗費(fèi)，按一定方法和程序，按照已經(jīng)確定的成本核算對(duì)象或使用范圍進(jìn)行費(fèi)用的匯集和分配的過(guò)程。成本校核的目的是為了在滿足機(jī)械工作要求和加工精度的基礎(chǔ)上，設(shè)計(jì)出最經(jīng)濟(jì)廉價(jià)產(chǎn)品。

Abstract: This issue is to manually press ratchet design, working conditions for mechanical devices, designed to meet actual work requirements presses. Press design includes gear shaft, rack, cabinet design and some components such as the selection of check. In the design process, according to the press the mission statement to provide the length, width, height, stroke, etc., to complete the overall design of the press. Mainly to human-based, driven by gear rack movement, with the ratchet to achieve self-locking hand wheel back rack, which drive the main design components of each system, relatively simple structure, typical of the hand press
The force analysis on the press to complete the design of gears. As the compact body presses, gear and shaft fused, causing the gear shaft structure. When the gear shaft to complete the bearing selection, shaft developed parts of the assembly program, checking the work of shaft strength requirements. Completed the design of the structure of the gear shaft, you can further define the size of its meshing of rack and rack of the process design rules. Rack of process planning, there are two options, compare the pros and cons of two options, choose the right one. Bearing on the press played an important role in the work, should check its strength, the design of its sealing devices. In the above work is completed, can be designed to press frame (box) design and the design of bearing end caps. Finally, the cost should be checked, the real cost accounting information processing is a data processing conversion process about to occur daily all funds have been spent, according to certain methods and procedures have been established in accordance with the object or the use of cost accounting range costs of collection and distribution process. The purpose of the cost of checking is in order to meet the job requirements and precision machinery, based on the most economical design of cheap products.
Key words: forcing press Ratchet institutions check the cost
