Planetary gear acceleration time
The article specifies that in modern conditions planetary gears are used in many vehicle assemblies. Use of a planetary gear enables to reduce a diameter of the main transmission thus to increase ground clearance. Use of planetary wheel gears increases unsprung weight and carries them away from the longitudinal axis of the vehicle and requires high-precision parts. To solve engineering problems it is necessary to determine transfer dimensions, gearing ratio, values of the direct stress and time of constant angular velocity during steady operation of the gearbox. The authors studied the motion of a planetary gear and found its acceleration in terms of Lagrange equations of the second kind. The given paper proves that the given inertia moment is constant, and input and output shafts rotate at start at the same velocity.
