行星齿轮传动变位系数选择及其几何计算 2K-H(NGW)型行星齿轮传动中,内啮合的接触强度比外啮合高2.5~5倍,所以传动I(a-g副)是薄弱环节,为了提高行星齿轮的承载能力,和发挥行星齿轮传动的优越性,通常采用角度变位,目的是为了提高外啮合a-g副的接触强度、抗弯强度和耐磨性能。由于行星齿轮传动要满足同心条件,当a-g副采用大正角度变位,必然导致g-b副也是大的正角度
Planetary gear transmission coefficient choice and its geometric calculation 2K-H (NGW) planetary gear transmission, the contact force of the internal gear 2.5-5 times higher than the external gear, so the transmission I (ag vice) is the weak link, in order to improve The carrying capacity of planetary gears, and the advantages of planetary gear drive, usually using the angle of displacement, the purpose is to improve the outer meshing ag contact strength, bending strength and wear resistance. As the planetary gear drive to meet the concentric conditions, when the a-g deputy with a large positive angle displacement, will inevitably lead to g-b Vice is also a large positive angle
