METHOD FOR MAKING A MOVEABLE CONNECTION Russian patent published in 2007 - IPC F16L27/10 

FIELD: mechanical engineering, possible use for making moveable connections.

SUBSTANCE: method for making a moveable connection includes an assembly of armature elements in press-form, creation of spaces between them by means of separating elements, filling of spaces with non-vulcanized elastomer and vulcanization of elastomer. Press-form is heated up to elastomer pressing temperature, the spaces are filled with elastomer under pressure, during filling the pressure is firstly increased gradually to 60 kgf/cm², then pressure is increased in impulses, increasing the value of pressure by 10 kgf/cm² at each following impulse. Each following impulse is generated after interval 60-70 seconds long and after pressure value of previous impulse becomes 2 times less. When pressure of 210-240 kgf/cm² is reached, process of filling spaces with elastomer is finished and press-form is heated up to elastomer vulcanization temperature, after elastomer vulcanization the press-form is cooled down and pressure is released.

EFFECT: increased reliability of connection.
