Device for engaging and disengaging pinion and rack in drive of nuclear reactor regulating element
Abstract
Abstract The invention relates to a device for engaging and disengaging the pinion and rack in the drive of a nuclear reactor regulating element. The device according to the invention is characterized in that the electromagnet which engages the pinion with, and disengages it form, the rack is installed coaxially with the rack axis whereas the swinging balance arm carrying the pinion is connected with the electromagnet core by articulated rods set at an acute angle to the rack axis. This simplifies the drive of the regulating element, reduces the lateral dimensions of the drive and cuts down the time elapsing from the moment of receiving the signal for the movement of the regulating element in the reactor zone to the beginning of its movement both under the regulating and emergency protection conditions.
