O-RING COMPRESSION LOAD MONITORING DEVICE Russian patent published in 2015 - IPC G01M15/00 

FIELD: machine building.

SUBSTANCE: device contains a base plate, mechanism of ring fixing on the plate and O-ring compression load pre-setting element. The instrument is fitted with the device for measurement of value of O-ring latching clearance designed as a photo-electric sensor, the housing of which is designed clamp-shaped and is installed on the base plate, on one shoulder of the clamp-shaped housing LED with collimating element are installed, and on the other one - photoresistor, connected with the current measurement device, the ring fixing mechanism is designed as a cross slide, installed with a possibility of movement in the base plate, and the rod installed in the cross slide with a possibility of rotation and axial movement and spring-loaded with reference to it, and on the rod end the hold-down clamp is installed with a possibility of interaction with the O-ring, meanwhile in the base plate the adjusting and thrust elements intended for setting of the O-ring into specified position on the base plate are placed with a possibility of movement and fixing in the specified position.

EFFECT: expansion of functionalities of the instrument due to possibility of measurement of elastic properties of wide range of O-rings, improvement of accuracy of measurements.
