Traction rotor for elevator traction machine

The invention discloses a traction rotor for an elevator traction machine. The traction rotor is characterized by comprising a spindle (1) and a rotor wall body (2) arranged at the outer side of the spindle (1); the spindle (1) and the rotor wall body (2) are integrally formed through a vertical cavity wall (3); meanwhile, a traction rope groove (4) is formed in the outer surface of one end of the rotor wall body (2). The traction rotor has the advantages that the structure is simple, rigidity is good, machining and manufacturing are easy, and the problem that the accumulated error is high when multiple parts are coordinated and the problems that the multiple parts are difficult to machine and manufacture and high in cost are solved.
