Elevator traction sheave

Abstract

The invention relates to an elevator traction sheave. The elevator traction sheave comprises a circular ring shaped wheel rim and a wheel cylinder arranged at the center of the wheel rim and coaxial with the wheel rim, wherein the wheel rim is connected with the wheel cylinder through an annular connecting portion perpendicular to the axial direction. One end of the wheel rim is provided with an auxiliary wheel rim, and the periphery of an outer wall of the auxiliary wheel rim is provided with radial sunken rope grooves. The elevator traction sheave is characterized in that the auxiliary wheel rim and the wheel rim are split and connected through threads. The elevator traction sheave is provided with the auxiliary wheel rim and the wheel rim which are combined in a split mode, facilitates replacement the auxiliary wheel rim with the rope grooves or a damaged auxiliary wheel rim suitable for different conditions, and prolongs the overall service life of the traction sheave while ensuring the connecting stability of the wheel rim and the auxiliary wheel rim. The number of the rope grooves can be adjusted, and the auxiliary wheel rim can be set to be combined type, so that the flexible control of shapes of the rope grooves is facilitated, and the advantages of different rope grooves are complemented. Limiting protrusions are further arranged at the opening positions of the rope grooves, thereby facilitating the stability of traction ropes in the rope grooves.

Description

technical field [0001] The invention relates to a traction sheave in elevator power equipment, in particular to a traction sheave with rope grooves. Background technique [0002] The power equipment of the elevator is mainly a traction machine, which specifically includes an electric motor, a brake, a coupling, a reduction box, a traction wheel and a frame. Among them, the traction sheave is also called the traction sheave or the driving sheave. It is the device for the elevator to transmit the traction power. on axis. At present, the rope grooves are directly set on the outer wall of the rim or the outer wall of the secondary rim extending from one end of the rim. Once a single rope groove is damaged, or it is barely used, the stability of the traction sheave is affected, or the entire traction sheave needs to be replaced. Bring inconvenience to normal work and increase costs. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art...
