CONNECTION OF COMPONENTS OF POWER MACHINES Russian patent published in 2008 - IPC F16B5/02 

FIELD: machine construction.

SUBSTANCE: proposed connection relates to machine construction, particularly to hydraulic machinery construction, and can be used for shaft locking hydroturbines and hydrogenerators, water wheels and rotors of hydrogenerators with shafts, and also in connections of working elements of agricultural machines. Connection of components of power machines, mainly hydraulic units, contains fixation in apertures of connected flanges of cylindrical bushing with stud bolts and nuts placed in them. The collar is executed with the inner protrusion I close proximity to the division plane with connected flanges, and the stud bolt is executed with a responsive external conic bond, interfits with the protrusion of the stud bolt. The stud bolt has a hexagonal head with a key, and its outer conic band with a smaller base directed to the head.

EFFECT: technology of manufacturing and assembling the unit is simplified, increase in the performance reliability on the connection.
