FRICTION SLEEVE Russian patent published in 2007 - IPC F16D13/75 F16D7/02 F16D13/64 

FIELD: mechanical engineering, possible use in precise mechanics devices for transmitting given driving torque, and also as means for protecting mechanical transmission from rotation elements, exceeding allowed value.

SUBSTANCE: in accordance to invention, device consists of body, driving shaft, set of spring-loaded friction elements, in turns connected to body and driving shaft with possible axial movement, springs and elements for controlling their force. Materials of components of sleeve structure are selected so that in force closed circuit of parts, as closing link of which springs are used, some elements, for example, friction set, have greater coefficient of temperature expansion in comparison with other parts of force circuit, and total change of geometric dimensions during change of temperature of construction additionally compresses springs, for example, during heating, or partially tempers them, for example, during cooling, compensating temperature changes of friction coefficient.

EFFECT: simplified construction, namely of mechanical part of unit for "automatic temperature stabilization of value of momentum being transmitted" due to selection of sleeve part materials, decreased dimensions, weight and industrial costs of sleeve manufacture.
