Example Embodiment

[0029] Example one

[0030] See figure 1 , An elevator traction bearing mechanism, comprising a traction bearing unit 2, a rotating wheel 1 that cooperates with the traction bearing unit 2. The traction bearing unit 2 is used to carry and move the car and aligns part of the circumference of the rotating wheel 1. For wrapping, the traction bearing unit 2 is in the shape of a flat belt and has a first working surface 21 and a second working surface 22. The first working surface 21 is a flat surface, and the two sides of the second working surface 22 respectively have a convex traction Guide the protruding guide body 5 of the bearing unit 2; the rolling surface of the rotating wheel 1 has two matching grooves 4 that cooperate with the two protruding guide bodies 5. When each protruding guide body 5 is matched with the corresponding fitting groove 4, there is a gap between the outer surface of the protruding guide body 5 and the inner surface of the fitting groove 4.

[0031] In this ...

Example Embodiment

[0035] Example two

[0036] See figure 2 The difference between this embodiment and the first embodiment is that the second working surface 22 of the traction bearing unit 2 is only provided with a protruding guide body 5 in the middle position, and the rotating wheel 1 is also provided with a right one only in the middle position. With the groove 4, the surface area of ​​a protruding guide body 5 is less than 30% of the area of ​​the second working surface 22.

Example Embodiment

[0037] Example three

[0038] See image 3 The difference between this embodiment and the first embodiment is that the first working surface 21 of the traction bearing unit 2 is matched with the rotating wheel 1. The rotating wheel 1 has a concave traction wheel groove 11, and the traction wheel groove 11 is The first working surface 21 is matched and has an axial clearance. In this embodiment, when the first working surface 21 is fitted in the middle of the traction sheave groove 11, there is an axial gap d between the two sides of the traction bearing unit 2 and the traction sheave groove 11, respectively. The width is 1%-10% of the width D of the traction bearing unit 2.

Abstract

The invention discloses an elevator traction-bearing mechanism which comprises a traction-bearing unit and rotary wheels matched with the traction-bearing unit, wherein the traction-bearing unit takes the shape of a flat strip, and comprises a first working surface and a second working surface; the first working surface is a plane; convex guiding bodies which protrude from the traction-bearing unit are arranged on the second working surface; matching grooves matched with the convex guiding bodies or concave-down traction wheel grooves matched with the first working surface are formed in the rolling surfaces of the rotary wheels; when the convex guiding bodies are matched with the matching grooves, gaps are formed between the outer surfaces of the convex guiding bodies and the inner surfaces of the matching grooves; and when the traction wheel grooves are matched with the first working surface; axial gaps are formed between the traction-bearing unit and the traction wheel grooves. Compared with the prior art, the elevator traction-bearing mechanism provided by the invention has the advantages that the traction-bearing unit can be effectively protected from a strip breakage phenomenon, the machining cost can be reduced, and higher safety and reliability can be achieved.

Description

technical field [0001] The invention relates to an elevator traction carrying mechanism used in a traction elevator. Background technique [0002] Chinese patent CN101044084B discloses an elevator with a flat belt as a load-carrying mechanism. The guide grooves on the belt and the guide ribs on the pulley cooperate to overcome the defects that the flat belt slips and falls off from the pulley or is damaged in advance. However, the technical solution of this patent also has some disadvantages: (1) the guide rib of the pulley requires high processing precision and high material cost; (2) the thickness of the belt at the guide groove of the belt is thin, during operation, if the guide rib of the pulley If it does not fit well with the guide groove of the belt, one side is under too much pressure, which may cause the flat belt to break or greatly shorten its life. [0003] Chinese patent CN204138090U discloses a traction suspension cable for elevators. One side working surface ...
