Abstract: With the continuous expansion of the subway network, the main line and depot have higher and higher requirements for the use of ZD-6 electric switch machine. In view of the structural characteristics of the friction coupling of ZD-6 electric switch machine, this paper analyzes the causes of the "contact rebound" phenomenon and the problem that the friction current does not up to standard during the operation of the on-site switch machine, and puts forward some daily maintenance methods.

Key words: electric switch machine, friction coupling, contact rebound, frictional current
