Rigidity is the capability of mechanical components to resist distortion when forces impressing on it. Its value can be obtained by measuring displacement when the part is impressed by force and become deformed. In china today, there has been no specialized measuring instruments for bearing rigidity yet, most users just calculate bearing rigidity by theory. Some others also use simple test devices to verify and test bearing rigidity, but it can only give a number of discrete points of rigidity, rigidity curve can not be mapped. So it can not be a true reflection of the bearing rigidity.
the bearing axial rigidity measuring instrument we developed is the specialized instrument for bearing axial rigidity. The instrument can provide the curve of bearing axial rigidity, in order to make the bearing parameter analysis easier and ensure the best rigidity of matching host.
this instrument is applicable to bearing production workshop, related research units and host matching units.
