TEAR-RESISTANCE TEST STAND OF FLOOR PANELS Russian patent published in 2014 - IPC G01N3/56 

FIELD: testing technology.

SUBSTANCE: stand comprises a space frame having a support base which serves for securing on it of the test sample of the floor panel, a vertical drive shaft connected to the gear motor mounted on the frame, a holder with roller bearings attached to the end of the drive shaft, mounted with the ability of rolling-off of the test sample, unit of generating a vertical load on the roller bearings for pressing them to the test sample with a predetermined force. The unit of generating a vertical load on the roller bearings comprises a lever mounted through the support assembly bonded to it, which has the sidewall symmetrically placed relative to the axis of the drive shaft, on the axis with the ability to turn in the vertical plane and resting, in two tension sensors attached to the sidewalls, on disc bearing plate with the base in the form of a spherical segment located in the mating socket of the housing of the roller tapered bearing mounted on the drive shaft and transmitting effort to the said shaft. On the lever arm a suspension is fixed, carrying removable loads.

EFFECT: enhancing the technological capabilities of the stand and simplifying maintenance of the stand when changing the load on the roller bearings.
