The TE 67 Pin on Disc Machine has the classic configuration of a pin or ball loaded vertically downwards onto a horizontally rotating disc. It also accommodates a variety of other test geometries.
The principle features of the unit are:
• very rigid pin and disc carriers, to allow nominally flat-on-flat contact
• use of pneumatic loading on the pin to reduce inertial loading effects in the contact
The pneumatic loading system is an important difference with other pin on disc designs that use dead weights and a load beam. Loading system inertia can significantly affect the friction and wear response.
The test disc is mounted on the machine spindle driven by a vector controlled a.c. motor. Encoder feedback ensures stable running speeds and a large turn-down ratio.
The pin carrier assembly consists of an aluminium block pivoted about a vertical axis through its centre. The track radius is set by moving the pin carrier assembly radially.
