Mutual Sliding of Working Surfaces as an Essential Element of a Needle Bearing's Function

Nachimowicz J., Korbut R.

Vol. 41, No. 2

97--107

The paper presents the kinematics of the friction pair on the example of a needle bearing. In the theoretical part we summarize the components of the summary resistance torque in working bearing - slip, micro-sliding and turning. Particular attention is focused on the phenomenon of mutual slip work surface cooperating friction pair. The study and analysis of the results shows us an area of active bearing operation, the share slip in the load zone and the type wear in the studied pairs friction. Defining the conditions wear in the studied pairs of friction will allow us to consciously improve the service life of the bearings needle.
