Ergonomie a manipulace s materiálem na pracovišti broušení čel

Abstract

The thesis deals with ergonomics, work settings and operation of the material used at the workplace of grinding of bearing ring´s fronts, particularly on the machine marked A0, in the world company for manufacture of bearings Koyo Bearings Czech Republic, s.r.o. Firstly, I acquainted myself with the given machine, then I observed the machine as well as motions of operator during the complete manipulation with semi-finished products. The greatest emphasis was put on moments of the highest muscular effort when semi-finished products were put into storage units (input) of the machine and subsequently taken away (output). Pictures of the process were evaluated according to four ergonomic methods, which I compared to each other and thanks to the resultant graphs I stated critical places (motions) for the operator. Based on this output, a project of relief devices as well as their financial demands and following installation was made. Subsequently, a new observation of a workplace was done and moreover, an evaluation of ergonomics. In the conclusion, I thoroughly studied the complete ergonomic situation before and after the installation of relief devices.
