POSSIBILITIES OF INCREASING THE WEAR RESISTANCE OF STEEL CHAIN WHEELS AS A RESULT OF CHANGES IN THEIR MANUFACTURING PROCESS
A. N. Wieczorek
The paper describes the problems of the operation of chain wheels of armoured face conveyors and the related assurance of the required wear resistance. An analysis of the current methods of manufacturing the chain wheels used in armoured face conveyors has also been performed. It has been found that a dynamic surface treatment can be used in the process of manufacture of these elements. As a part of the study, the results of wear tests for the standard and modernized variants of chain barrels have been presented, which confirmed the validity of the changes made in the process.
