When gear hub assembled with gear sleeve as synchronizer assembly

gear sleeve could not be set into gear hub

the smoothness

tilt degree is unqualified

which is the main reason for the failure of assembly.The yield synchronizer assembly and assembling efficiency are severely reduced.For this reason

on the basis of analyzing the assembly features of synchronizer gear hub and gear sleeve

a mathematical model for effect of backlash is derived by using the method of mathematical derivation.Then a matching process is presented under the existing conditions.Finally

through the experimental verification

the matching process is simple and easy to implement

in under the premise of the cost of testing isn’t increased

and the matching efficiency for synchronizer gear hub and gear sleeve could be improved.
