Claims

[Claims for Utility Model Registration] Consisting of a fixed support part, an upright shaft supported by the support part so as to be movable in the axial direction and relatively rotatable, and a torque arm attached perpendicularly to the upright shaft. a torque axis; and disposed coaxially aligned below the upright axis;
It is rotated by a motor, etc., and a pair of disk-shaped test pieces, which are the materials to be measured, are sandwiched between the upper end surface of the upper end surface and the lower end surface of the upright shaft, and rotated under a predetermined load in a state of frictional contact. a drive shaft; a pressurizing load cell connected to the upper end of the torque shaft via a spring in order to apply a predetermined pressing force to the pair of test pieces; and a pressurizing load cell attached to the tip of the torque arm of the torque shaft. a load cell that measures frictional force as rotational force; and a vertical friction and wear tester in which each of the above-mentioned members that apply pressing force other than the load cell that measures the rotational force is arranged substantially vertically, The testing machine is further configured such that the upright shaft of the torque shaft is restrained from relative movement in the axial direction with respect to the upright shaft via a bearing at a position intermediate the support portion of the upright shaft and the test piece;
a mounting jig that is relatively rotatably mounted, and a length and spring constant set between the mounting jig and the support part that are appropriate for offsetting the weight of the torque shaft. 1. A vertical friction and wear testing machine, characterized in that it has a pressurizing force loading structure that can offset the self-weight of a torque shaft.
