필드 부하를 활용한 정유압기계식 변속시스템의 기어 해석

초록

A tractor is an agricultural machine that performs farm work, such as cultivation, soil preparation, loading, bailing,and transporting, through attached working implements. Farm work must be carried out on time per the growingseason of crops. As a result, the reliability of a tractor’s transmission is vital. Ideally, the transmission’s designshould reflect the actual load during agricultural work; however, configuring such a measurement system is time- andcost-intensive. The design and analysis of a transmission are, therefore, mainly performed by empirical methods. Inthis study, a tractor with a measurement system was used to measure the actual working load in the field. Itshydro-mechanical transmission was then analyzed using the measured load. It was found that the velocity factor, loaddistribution factor, lubrication factor, roughness factor, relative notch sensitivity factor, and life factor affect the gearstrength of the transmission. Also, loading conditions have a significant influence on the reliability of thetransmission. It is believed that transmission reliability can be enhanced by analyzing the actual load on thetransmission, as performed in this study.
