Problems solved by technology

[0004] In view of this, the purpose of the present invention is to solve one of the above technical problems at least to a certain extent. On the one hand, it provides a coated belt traction pulley, which reduces the third work of the elevator when the contact surface between the traction pulley and the cover belt is clean. In this case, the risk of the elevator car being lifted solves the problem that the tra

Example Embodiment

[0048] The technical solutions in the embodiments of the present invention will be apparent from the embodiments of the present invention, which will be described below. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0049] Such as figure 1 with figure 2 As shown, an elevator cladding tape is incorporated between the traction wheel 10 including a traction surface 101 for engaging and driving the cladding strip 20, the traction surface 101 having one or more, the traction surface 101 It can be a convex contact surface or a flat contact surface; between the plurality of traction surfaces 101 can be spaced by a boss 102; both ends of the traction wheel 10 are limited by the flange 103. The traction surface 101 has a tiny pit and a projection, covering a protective layer 30; the diameter of the pulse surface 101 is 3 μm to 8 μm. Among them, the annular directional arith...

Abstract

The invention discloses an elevator wrapping belt traction wheel and a manufacturing method. The traction wheel involves a traction surface used for being connected to and driving a wrapping belt, the traction surface is provided with tiny pits and protrusions and covered with a protective layer, the arithmetic mean roughness of the traction surface in the circumferential direction is 3 micrometers-8 micrometers, the manufacturing method comprises the following steps that the traction wheel is formed, and the traction surface of the traction wheel is subjected to sand blasting treatment and QPQ salt bath tufftriding treatment to form a protection layer. According to the elevator wrapping belt traction wheel and the manufacturing method, the traction wheel provided the characteristics of stable friction coefficient and excellent corrosion resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of traction sheaves, in particular to an elevator coated belt traction sheave and a manufacturing method thereof. Background technique [0002] In the elevator components, the traction wheel will drive the covering belt to run, thereby driving the elevator car and counterweight to run up and down, and keeping the car and counterweight from falling; when the surface of the traction wheel is accidentally stained with oil, water, dust and other pollutants After that, the coefficient of friction between the traction wheel and the covering belt will become smaller, and the traction force between the traction wheel and the covering belt will be reduced, which may cause the risk that the traction force is not enough to drive the car or keep the car stationary . Therefore, in order to ensure the traction force after the surface of the traction wheel is polluted, it is usually necessary to form a certain roughness i...
