HEAT TRANSFER COEFFICIENTS GRADIENTS DETERMINING METHOD DURING THE BELT-SHOE BRAKE TRIBOSYSTEM FORCED AIR-LIQUID COOLING HEAT EXCHANGE INTENSITY EVALUATION Russian patent published in 2019 - IPC F16D65/80 F16D49/08 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Proposed is the heat transfer coefficients gradients determining method during the belt-shoe brake tribosystem forced air-liquid cooling heat exchange intensity estimation, in which the heat flow between the tribosystem other components distribution coefficients determination is performed in a certain sequence. First, finding the heat transfer coefficients in heat exchange processes through the multilayer objects. Then, according to the heat transfer coefficients values in friction pairs, which are in the closed or open state, determining the heat distribution coefficients between their elements in the process of braking. Determining the heat flow distribution coefficients between the tribosystem other components. After that, by the dependencies determining the heat transfer coefficients gradients in heat exchange processes through the brake tribosystem multilayer objects.

EFFECT: enabling increase in the belt-shoe brake metal-polymer friction pairs durability by reducing the energy load of their surface layers.
