Abstract
An elevator traction transmission mechanism comprises a traction generator, a litter box connected with the traction generator through the traction transmission mechanism. The traction generator comprises a first traction strand and a second traction strand wrapped on the output dial, a first chain wheel as the crown block for the first traction rope, a second chain wheel as the crown block for the second traction rope. One side of the first traction rope and the second traction rope are respectively connected with the top of the litter box symmetrically, which can balance the litter box pulled by the two traction ropes in operating. And the other side of the first traction rope and the second traction rope are respectively connected with the counterpoise piece, which thus prevents the counterpoise piece from shaking in the operating, and ensures the litter box operate vertically and stably. In doing so, the operating guide for the litter box and the counterpoise piece can be omitted, and thus saves the costs for elevator installation.
