Abstract

The present application provides a method and an apparatus for determining wear depth for solving the problem of insufficient calculation accuracy of cumulative wear depth of a compound planetary geartransmission system in the prior art. The method includes: determining a first average bias load coefficient formed by the driving wheel and the driven wheel before the first time according to deformation parameters of the driving wheel and the driven wheel at the first time and tooth side clearance; calculating a Hertz contact pressure of the driving wheel and the driven wheel based on a first average bias load coefficient and gear parameters for calculating a linear load on a unit tooth width of the driving wheel and the driven wheel; calculating the wear depth of the driving wheel and thedriven wheel at the first time according to the Hertz contact pressure, the number of revolutions of the driving wheel and the driven wheel, the actual wear duration of the driving wheel and the driven wheel, and the relative slip rate of the driving wheel and the driven wheel; calculating the cumulative wear depth of the first system at the first time based on the wear depth of the driving wheeland the driven wheel at the first time.

Description

technical field [0001] The present application relates to the technical field of planetary gear transmission, and relates to a method and device for determining wear depth. Background technique [0002] At present, the static calculation method of tooth surface wear is mostly used in the industry. The static calculation method of tooth surface wear means that the growth rate of the target result changes with time. The relationship between the surface pressure and other physical quantities, by calculating the Hertz contact pressure, relative slip rate, wear duration and wear coefficient at each observation point, the distribution of the tooth surface wear of the driving wheel and the driving wheel along the tooth profile direction is obtained law. However, using this static tooth surface wear calculation method to calculate the tooth surface wear of the compound planetary gear has poor load sharing characteristics, which leads to the problem of insufficient calculation accur...
