【摘要】：斜齒輪蝸桿傳動機構傳動比大、傳動平穩(wěn)、可自鎖,用來傳遞空間交錯兩軸的動力。塑料斜齒輪設計簡單、易于加工、重量輕、自潤滑性好、噪音小、制造成本低,廣泛應用于汽車、機械、家電等領域。因此,關于塑料斜齒輪鋼制蝸桿傳動機構的研究,有重要的應用價值。本文以“小型乘用車自動控制離合器系統”項目為基礎,項目編號為:2012GH710902,主要對塑料斜齒輪鋼制蝸桿傳動機構設計參數、傳動效率、自鎖性進行理論與試驗研究,對其齒面應力進行動態(tài)有限元分析,為斜齒輪蝸桿傳動機構的參數設計、材料選擇、工藝選取等提供指導,具有實用價值。通過分析斜齒輪蝸桿傳動輸入、輸出功率的方法,研究了斜齒輪蝸桿傳動效率、傳動條件、自鎖條件,分析了壓力角、螺旋角、摩擦系數對傳動效率和自鎖性的影響。進行了傳動效率、自鎖性能測試試驗。研究結果表明,摩擦系數增大,傳動效率降低,自鎖性增強;螺旋角增大,傳動效率提高,自鎖性減弱;壓力角增大,傳動效率降低,自鎖性增強。當螺旋角約為5.2°,摩擦系數約為0.09時,是斜齒輪蝸桿傳動自鎖的臨界參考值。斜齒輪蝸桿傳動設計參數對傳動效率、自鎖性影響的研究結果在參數設計階段對衡量蝸桿傳動機構傳動效率、自鎖性有指導意義。本文對某車型自動控制離合器系統塑料斜齒輪鋼制蝸桿傳動機構進行了動態(tài)有限元分析,研究了塑料斜齒輪嚙合過程中齒面應力分布、變化情況。斜齒輪齒數為69,壓力角為10.5°,螺旋角為5.16°時,斜齒輪蝸桿傳動機構有三個齒為主要嚙合齒,齒面最大應力變化較小;斜齒輪齒面嚙合點由齒頂向齒根移動,臨近齒根后又沿嚙合點軌跡向齒頂方向移動較小位移,嚙合點軌跡與斜齒輪端面呈一定角度;斜齒輪在靠近齒根部位接觸應力較高;斜齒輪材料彈性模量越小,輪齒完成嚙合的時間越長。本文的研究工作可為企業(yè)開展齒輪、蝸桿傳動產品的仿真分析工作提供參考。按本文參數選擇方法設計的塑料斜齒輪鋼制蝸桿傳動機構,已應用在企業(yè)某車型自動控制離合器系統中,在機械強度、傳動性能上都能滿足使用要求。本文研究的斜齒輪蝸桿傳動設計參數對傳動效率和自鎖性的影響規(guī)律、動態(tài)接觸有限元分析流程,已應用于企業(yè)蝸桿傳動新產品研發(fā)中,對齒輪、蝸桿傳動系列產品的開發(fā)有指導意義。
[Abstract]:The helical gear worm drive mechanism has the advantages of large transmission ratio, stable transmission and self-locking, which is used to transfer the power of space staggered two axes. Plastic helical gears are simple in design, easy to process, light in weight, good in self-lubricity, low in noise, low in manufacturing cost, and widely used in automobile, machinery, household appliances and other fields. Therefore, the study of plastic helical gear steel worm transmission mechanism has important application value. Based on the project of "automatic clutch control system for small passenger cars", the project number is: 2012GH710902. The design parameters, transmission efficiency and self-locking property of worm drive mechanism made of plastic helical gear and steel are studied theoretically and experimentally in this paper. The dynamic finite element analysis of tooth surface stress provides guidance for parameter design, material selection and process selection of helical gear worm drive mechanism. It is of practical value. By analyzing the input and output power of helical gear worm transmission, the transmission efficiency, transmission conditions and self-locking conditions of helical gear worm drive are studied. The influence of pressure angle, spiral angle and friction coefficient on transmission efficiency and self-locking property are analyzed. The transmission efficiency and self-locking performance were tested. The results show that the friction coefficient increases, the transmission efficiency decreases and the self-locking property increases; the spiral angle increases, the transmission efficiency increases and the self-locking property weakens; the pressure angle increases, the transmission efficiency decreases, and the self-locking property increases. When the helical angle is about 5.2 擄and the friction coefficient is about 0.09, it is a critical reference value for helical gear worm drive self-locking. The results of the study on the influence of the design parameters of helical gear worm drive on transmission efficiency and self-locking are of guiding significance in the stage of parameter design for measuring the transmission efficiency and self-locking of worm transmission mechanism. In this paper, the dynamic finite element analysis of the plastic helical gear steel worm drive mechanism in the automatic control clutch system of a vehicle is carried out, and the stress distribution and variation of the tooth surface during the meshing process of the plastic helical gear are studied. When the number of helical gear teeth is 69, the pressure angle is 10.5 擄, and the helical angle is 5.16 擄, the helical gear worm drive mechanism has three teeth as the main meshing teeth, the maximum stress of the tooth surface is small, and the meshing point of the helical gear tooth surface moves from the top of the tooth to the root of the tooth. Near the root of the tooth, it moves a little displacement along the trajectory of the meshing point to the top of the tooth, and the trajectory of the meshing point is at a certain angle with the end face of the helical gear, the contact stress of the helical gear near the root of the tooth is higher, the elastic modulus of the helical gear material is smaller, The longer the teeth finish meshing. The research work in this paper can provide a reference for enterprise to carry out the simulation analysis of gear and worm transmission products. The worm drive mechanism of plastic helical gear and steel which is designed according to the method of parameter selection in this paper has been applied to the automatic clutch control system of a certain vehicle in an enterprise. The mechanical strength and transmission performance can meet the requirements of application. The influence of helical gear worm drive design parameters on transmission efficiency and self-locking, dynamic contact finite element analysis flow, has been applied to the research and development of new products of worm drive in enterprise. The development of worm transmission series is of guiding significance.
