Návrh elektrického mechanizmu otáčania výložníka stĺpového žeriava pre manipuláciu s kalovými čerpadlami

Abstract

The article is a continuation of the issue of the technical solution of the hinge for handling sludge pumps in the Jaslovské Bohunice nuclear power plant. The main goal is the design of the electric jib rotating mechanism. It was based on the previous proposal for placing the boom consisting of a dimensional calculation of the new support column and the proposal for placing the boom on this column. The save consisted of two bonds. The upper support of the boom was solved using a rolling bearing fixed in the upper part of the column. The bottom bearing contains an axial plain bearing and a fixed gear as part of the rotating mechanism. In the next step, it is necessary to design the attachment of the selected electric motor with a planetary gearbox and a pinion for this construction. The priority in the design will be mainly to observe the axial distance of the gears, but also to consider the mounting method given by the manufacturer and the torque generated by the engine. A holder in which the motor is attached and then attached to the structure will be designed. Thanks to this, the axial distance will be fulfilled. In addition to supporting the motor, the holder also serves as a radial bearing lock, preventing the bearing from being accidentally pulled out. The result of calculations and designs will be 2D diagrams and 3D visualization of the new construction.
