FACILITY FOR MODULES CONNECTION Russian patent published in 2010 - IPC B23B31/06 

FIELD: machine building.

SUBSTANCE: facility consists of coupling screw placed in connecting orifice of base module whereon shank end of end module and support component are based. Also the support component is composed of balls placed in a groove on the coupling screw and resting on the end of a boring. The boring is made in a cylinder part of the orifice of the base module to transfer axial force at its coupling with the end module. The end module has a radial threaded orifice for installation of balls of the support component and a screw preventing support component balls falling out. To raise reliability of connection axis of the radial threaded orifice is set off relative to axis of the balls of the support component. Conic surface is made on the screw to contact side surface of the balls of the support component and at a certain moment of screw tightening the support component is wedged at this position thus fixing the moment of coupling screw tightening. It prevents support component slipping and coupling screw unscrewing under effect of vibration.

EFFECT: raised reliability.
