JOINING UNIT OF OPERATIVE PARTS OF POWER MACHINES Russian patent published in 2009 - IPC F16B5/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, particularly to hydraulic mechanical engineering, and can be used for joining of shafts with impellers of hydraulic turbines and labour bodies of agricultural machinery. Joining unit of operative parts of power machinery, mainly hydraulic machines, contains bushes installed in openings of joined parts and studs open located in it. Plain spigots of bushes, implemented with outside threaded surface, are bearing on surface of joined part, in opening of which bushes are open installed, and from the side of which on studs there are tightened screws. In openings of other joined part of bush there are forced fit, and into threaded openings of other joined part there are tightened studs.
