Abstract: The rolling testing apparatus in reciprocating rolling is
developed from tension-compression hydraulic machine with a high
precision, and a number of tests are performed. From the test result
analyzing, the conclusions could be obtained as follow: the coefficient
of friction is variation when the body begins to roll from rest, and it
is sharp affected with the wear style changing.
Key words: Rolling Rolling-sliding contact Coefficient of friction
