Description
Technical field
The present invention relates to a kind of detection method, specifically a kind of oil seal radical force method of testing.
Background technology
The method of test oil seal radical force, is substantially all tested oil sealing on test axle at present, and tests axle
It is to be separately fixed on two semiaxis, one of semiaxis is fixed, the movable sensor of another semiaxis, is installed on fixed semiaxis
One force snesor, the core parts of the sensor are foil gauges, and force value is converted into according to the foil gauge deflection measured, so that
Draw the radial load of oil sealing.
But it is due to that the physical dimension of test axle will occur when tested oil sealing is installed on test axle
Change, diameter can diminish.The nominal diameter of such as test axle is φ 15.4mm, is loaded onto after oil sealing, and the diameter of test axle will become
Into φ 15.28mm, radial direction enclasping force is bigger, and the change in size for testing axle is also bigger.What we to be tested is test axle deformation institute
The radial load of the tested oil sealing characterized, it is tested that the test axle deformation for being less than nominal dimension actually tested is characterized
The radial load of oil sealing.Investigated according to applicant, being substantially for current home and abroad is tested by above-mentioned method of testing, therefore
The result drawn not oil seal radical force under nominal dimension.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, discloses a kind of oil seal radical force method of testing, is desirably to obtain
Real oil seal radical force, is that this present invention is adopted the technical scheme that：
The present invention discloses a kind of oil seal radical force method of testing, the displacement of the measurable fixed semiaxis of the first displacement transducer（Power
The deflection of sensor）, the displacement of the measurable mobile semiaxis of second displacement sensor, test axle original state is tested formation testing
Envelope nominal diameter subtracts 1mm position；When the realtime deformation that the real-time displacement amount of mobile semiaxis subtracts fixed semiaxis is just equal to
During 1mm, processor control servomotor stops operating and is kept for one section of retention time set in advance immediately, and now display shows
The average value of radial load showing, being converted into the force sensor measuring of fixed semiaxis according to default operation program is tested
The radial load of formation testing envelope.
Compared with prior art, the oil seal radical force that the present invention is obtained is the radial load under its nominal dimension, closer to it
Actual radial load.
