METHOD OF DYNAMIC SHOCK-ABSORBING OF POWER TRANSFER SHAFT, IN PARTICULAR SUPERCRITICAL SHAFT, AND SHOCK-ABSORBING DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC F16C27/04 F16F15/23 

FIELD: machine building.

SUBSTANCE: invention relates to method of dynamic shock-absorbing of power transfer shaft, in particular supercritical shaft, and shock-absorbing device for its implementation. System of dynamic shock-absorbing on the power shaft (10) contains input (12) and output (14) roll bearings to transfer power (12r, 14r), bearings are installed in two casings (32, 34), and encircling teeth (15) of the geartrain for speed reduction. The output bearing (14) is paired with at least additional roll bearing (20, 20r), connected with compression shock-absorber (26) to make axial output shock-absorber (20, 26), eccentric relatively to the input bearing (12) against engagement of teeth (15). Two output bearings (2, 14) can be connected by the resilient cage carrier (24) installed on common casing (34). The system is used in power transfer shafts, in particularly in supercritical shafts in turbine machines.

EFFECT: creation of the system ensuring use of thee sufficient shock-absorbing on the power shaft upon hardness keeping at level of the front bearing, to exclude disengagement of teeth of the power geartrain of the drive tooth-wheel.
