This paper describes a bal ot lifting mechanism which is commonly used in the subway ticket machines-bal screw mech-anism, and analyzes its advantages and disadvantages. For the problems existing in the bal screw mechanism, it designs a new bal ot lifting mechanism, which is control ed by spring. From the design thought and the key technologies,it also describes the selec-tion of spring material, the bearing work load and the deformation.
