Transmission Error of Static Characteristic for Planetary Gear Transmission in the Field of High-power Tractor

According to the structural characteristics of planetary gear transmission in the field of high-power tractor, a statics of calculative model for the load distribution of planetary gear transmission system is established. With the theory of equivalent mesh error, the main factors which affecting the transmission error of the planetary gear transmission are obtained. With the method of controlling variables, the influence law of these main factors to load sharing coefficient is researched. The most severely and acutely effects of error factors are obtained. According to the coupling formula of transmission error when the phase angle is the same, the main error factors of planetary gear transmission are coupled. Several groups of coupling schemes are put forward. Under these coupling schemes, the transmission error of planetary gear transmission is explored. The most severely and acutely factors which affecting the transmission error are obtained. According to these coupling schemes, improvement measures are put forward to reduce the transmission error. The scientific theoretical basis is provided for designing of planetary gear transmission in the high-power tractor.
