DEVICE FOR DETERMINING THE COEFFICIENT OF STATIC FRICTION FORCE Russian patent published in 2022 - IPC G01N19/02 

FIELD: measuring technology.

SUBSTANCE: invention relates to measuring devices. The device for determining the coefficient of static friction contains a platform pivotally mounted on a frame with a scale, a three-shouldered body connected to the platform by a restrictive leash, a traction device and spacers with slots. A vertical rectangular cross-section rack is attached to each of the three arms of the three-shoulder body, on two opposite sides of which plate springs with elastic pads are fixed, and an oval cam is placed between them, fixed at one end of a horizontal roller with a rotary lever at its other end, the roller is fixed axially in the hole of the bracket, rigidly attached to the vertical rack with a side perpendicular to the placed plate springs.

EFFECT: ability to reduce the complexity of measurements.
