Description
Technical Details

The clutch plate friction (DN – 005) is a wall mounted apparatus. It is designed to determine the coefficient of friction and minimum torque to maintain rotation. It investigates the relation between the minimum torque to maintain rotation, the axial load and the friction disc diameter.

On top of this stationary disc sits an upper aluminum alloy plate whose shaft rotates in ball bearings but which is in direct contact with the stationary plate.
Between the lower and upper plate are friction discs, of 3 different sizes. Each disc is positioned in turn.
The minimum force on the friction disc is the self-weight of the upper plate, but the contact pressure can be increased by adding weights to the upper plate.
Pure torque is applied to the upper plate through two loaded cords and pulleys. The cords wrap around a groove in the upper plate.
Three interchangeable friction discs are supplied of different diameters. Each one sits onto location pins in the lower plate.
A set of calibrated weights is supplied which enable the loading force to be varied and applied torque to be adjusted also.
