畢業(yè)設(shè)計(jì)說明書(論文)中文摘要
行星齒輪傳動與普通齒輪傳動相比,它其具有體積小、質(zhì)量輕、結(jié)構(gòu)緊湊和傳動效率高等優(yōu)點(diǎn),還有就是在傳遞動力時(shí)它可以入行功率分流,同時(shí),其輸入軸與輸出軸具有同軸性,即輸出軸與輸入軸均設(shè)置在同一主軸線上,所以,行星齒輪傳動現(xiàn)已被人們用來代替普通齒輪傳動,作為各種機(jī)械傳動系統(tǒng)中的減速器、增速器和變速裝置尤其是對于那些要求體積小、質(zhì)量小、結(jié)構(gòu)緊湊和傳動效率高的航空發(fā)動機(jī)、起重運(yùn)輸、石油化工和兵器等的齒輪傳動裝置以及需要變速器的汽車和坦克等車輛的齒輪傳動裝置,行星齒輪傳動已得到了越來越廣泛的應(yīng)用。

Title The Design of Riding lawn mower Planetary Gear
Transmission
Abstract
Planetary gear transmission compared with the ordinary gear transmission,
it has small size,light weight,compact structure and high efficiency transmission. Furthermore,it can join the power split when in the transmission of power,and the input shaft and output shaft is coaxial,that is to say the output shaft and input shaft are set in the same axis line.Therefore,the planetary gear transmission has been used to replace the ordinary gear transmission ,as a reducer in a variety of mechanical transmission system,accelerator and the gearshift device,especially those requiring small size,light weight,compact structure and high efficiency transmission ,such as aircraft engines,lifting and transportation, petrochemical and weapons those gear transmission device.and also the cars and tanks ,and other vehicles with the need of gear transmission device.Planetary gear transmission has been increasingly widely used.
