| Abstract: | This article introduces the shearer 6LS-03 which is being used in Shenfu_Dongsheng coal company of Shenhua Group often occurs break down_chain broken on the head or tail of the shearer when it occurs in the course of practical use.Facing with this problem,it analyses on the situations of bearing forces of drawing system in shearer and the reasons why the chain is always broken.At last,it puts forward the new methods of improvement and gives some new thinkings of design. |
| Keywords: | shearer covered_chain style drawing system analysis on the bearing forces the factors of the safety |
