APPARATUS FOR PRESSING OUT SHAFT-SLEEVE TYPE ASSEMBLIES Russian patent published in 2004 - IPC

FIELD: repairing works, namely dismounting pinions from shaft of traction electric motors of locomotives.

SUBSTANCE: apparatus for pressing out shaft-sleeve type assemblies includes in addition needle type regulator mounted on multi-cavity reversing drive, switch connected with inductor and having on one of its end rotatably mounted clamp in the form of shaped ring and power cylinder secured to its other end; timer whose one control outlet is connected with switch of inductor and other outlet is connected with electrically controlled distributor. Needle type regulator is connected to distributor through additional pipeline. Profiled needle of regulator is matched with jet placed in inter-cavity duct of forward and backward strokes of multi-cavity reversing drum-blade type drive. Said drive has rotary levers secured to mutually shifted members. Shaped ring includes limiting member in the form of thickened portion along periphery with circular inner turning joined with annular stop on outer magnetic circuit of inductor. Central openings of said part have size corresponding to outer surface and reciprocal to shape of dismounted sleeve. Poles of outer magnetic circuit are turned to center and adjoined with ends of dismounted sleeve; between them solenoid is arranged.

EFFECT: possibility for keeping size and surface quality for secondary joining of parts, lowered effort of pressing out.
