ABSTRACT:
An endless belt type bench testing apparatus has a flexible metallic endless belt wound over a pair of rotary drums for rotation therewith. The apparatus has a hydraulic belt lubricating and support structure, in which a liquidus lubricating medium layer, such as a water layer, between the belt and a supporting structural member at an intermediate portion between the rotary drums. A seal structure for preventing the liquidus lubricating medium from leaking from a drain circuit, is provided at least at the downstream end of the clearance with respect to a direction of the belt motion. The seal structure includes a porous seal member associated with a resilient member to be resiliently biased toward an endless belt for establishing liquid-tight seal. The porous seal member is designed for absorbing part of drained liquidus lubricating medium. The porous seal member is also associated with a liquid removing means for removing the liquidus lubricating medium therefrom for maintaining sufficient liquid absorbing capacity of the seal member.
