FIELD: machine building.
SUBSTANCE: invention relates to mechanical engineering and can be used in thermal control systems of aviation and rocket technology products. Electric pump unit comprises a housing, an electric motor installed in it, and a double-support hollow shaft of a pump with an impeller connected to the electric motor shaft through a torsion clutch. Torsion shaft of the coupling is located in the cavity of the double-support hollow shaft of the pump and is connected with it by a free end. At the opposite end of the double-support hollow shaft of the electric motor, an internal thread is made into which the roller is screwed with a protrusion entering the groove at the end of the torsion shaft. Direction of the thread on the roller and double-support hollow shaft of the pump coincides with the direction of rotation of the motor shaft.
EFFECT: invention is aimed at improving manufacturability.
