Method for eliminating eccentric wear of oil distribution disc of high-pressure plunger variable pump

The invention discloses a method for eliminating eccentric wear of an oil distribution disc of a high-pressure plunger variable pump. The method comprises the following steps that a, a three-dimensional space coordinate system is established; b, an oil film pressure distribution nephogram is established between a cylinder body and the spherical surface of the oil distribution disc through simulation; c, based on the three-dimensional space coordinate system and the oil film pressure distribution nephogram, simulation calculation is carried out to obtain deflection lateral force of the oil distribution disc in the X-axis direction, the Y-axis direction and the Z-axis direction and three deflection torque around the X-axis direction, the Y-axis direction and the Z-axis direction; and d, an oil duct is arranged between an oil inlet hole and an oil outlet hole of the oil distribution disc, a first oil port connected with the oil duct is formed in the end face, close to the oil inlet hole, of the oil distribution
