Description

technical field

[0001] The invention relates to the technical field of oil seal radial force testing, in particular to an oil seal radial force testing method. Background technique

[0002] The radial force of an oil seal is a key parameter to characterize its sealing performance and service life. Selecting an oil seal with a suitable radial contact force is an important basis for structural optimization. Therefore, the measurement of the radial force of an oil seal is particularly important. The current method of testing the radial force of the oil seal basically encapsulates the oil to be tested on the test shaft, and the test shaft is fixed on two half shafts, one of which is fixed and the other half shaft is a displacement sensor. A force sensor is installed on the fixed half shaft. The core element of the sensor is a strain gauge. The measured deformation of the strain gauge is converted into a force value to obtain the radial force of the oil seal. In this way, the me...
