FIELD: machine building.

SUBSTANCE: invention relates to the compensation device of the ratchet wheel for overhead system of contact wires of high speed electric railroad. The compensation device of the ratchet wheel contains casing (1) of the ratchet wheel, a brake bracket (2) for the ratchet wheel, long pin (3), connecting panels (4) of the ratchet wheels and brake bracket, lock panel (5), balancing wheel (6), steel wire I (7), steel wire II (7'), and wire clamp (8). The casing (1) of the ratchet wheel is installed on the axle (11) of the ratchet wheel by means of pair of self-lubricating journal bearings (10). Two ends of the axle (11) of the ratchet wheel are fixed on the front end of the connecting panels (4) of the ratchet wheel and brake bracket, and are equipped with end face self-lubricating bearings (14) installed between the connecting panels (4) of the ratchet wheel and brake bracket, and self-lubricating journal bearings (10).

EFFECT: jamming and hard rotation of the ratchet wheel are excluded, increased efficiency of transfer upon casing shift of the ratchet wheel.
