TWIN DISK TESTING APPARATUS

摘要

The invention relates to an apparatus (1) for testing mechanical strength over time of materials intended for the production of mechanical components, comprising a frame (2) and a supporting base (3) adapted to support a test group (4). The test group (4) comprises a pair of line shafts (5) intended to support each a respective disk (310a, 310b) made of a material to be tested and placed along parallel and coplanar axes of rotation, such that the two disks (310a, 310b) slide and/or roll against one another during the rotation. The apparatus (1) further comprises at least one electric motor (6) connected to a first line shaft (5a) of the pair of line shafts (5) by means of a transmission member (7), so as to apply a rotational motion to the first line shaft (5a). The test group (4) is fixed to a plate (404a) resting on anti-vibration mounts (404b) in turn resting on the supporting base (3).
