DEVICE FOR HYDRAULIC DISTRIBUTION AND ASSEMBLY OF CONNECTIONS OF BEARING RINGS WITH NECK OF AXLE OF WHEEL PAIRS

摘要

1. Device for hydraulic molding and assembling joints of bearing rings with necks of axles of wheel pairs, containing a hydraulic part for mechanical supply of working fluid to the interface, having a working hydraulic cylinder housing made in the form of a cup with a central hole in its bottom and provided with an opposed ring seal in the specified hole with a piston rod placed inside it coaxially attached to the neck of the axis and an end seal on the open end of the said glass, as well as a mechanical part for closing heating the specified working hydraulic cylinder on a dismountable bearing ring and axially moving the latter from the neck to the piston rod, the outer diameter of which is less than the diameter of the axis of the axis by an amount that provides clearance with the bearing ring removed from it, characterized in that the main body of the working hydraulic cylinder, made in the form a two-stage cylindrical cup, has a hollow piston-rod with an internal threaded part and O-rings of the mentioned internal step cavities, equipped with an oil pipe with a shut-off valve in the walls of this glass, and the existing auxiliary housing, made in the form of a stepped thick-walled ring with two opposed inner conical surfaces and oil supply channels in its walls, is fixed coaxially in the inner cavity of the main body, equipped with an annular seal, with one conical surface of the auxiliary housing interacts with the conical sleeve of the high-pressure ring seal on the outer surface of the front bearing ring, secured
