UNIT FOR STUDYING BEARING FRICTION - MBF

SYSTEMES INNOVANTS

The Unit for Studying Bearing Friction, "MBF", has been designed to study sliding friction in slide bearings and rolling bearings. Since rolling friction is very little, rotational dynamics basic tests can be performed with the inertia flywheel.

Description Générale

The Unit for Studying Bearing Friction, "MBF", has been designed to study sliding friction in slide bearings and rolling bearings. Since rolling friction is very little, rotational dynamics basic tests can be performed with the inertia flywheel.

It consists of a shaft with a cable drum and inertia flywheel supported on the bearings under study.

Three pairs of exchangeable bearings shells made of different material, a pair of ball bearings and a pair of rolling bearings are supplied to study friction in different types of bearings.

Different masses are hanged from the drum cable, generating different torques equivalent to the frictional moment when starting the rotation.
