Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide shoes, in particular to a rolling guide shoe. Background Art

[0002] As the parts of the elevator running up and down, the guide shoes play an important role in the comfort of the car. At present, the guide shoes can be divided into sliding guide shoes and rolling guide shoes. The sliding guide shoe structure is to fix the nylon U-shaped groove in the metal frame, and the U-shaped groove and the metal frame are fixed by rubber. Since the nylon U-shaped groove and the guide rail are sliding, friction and noise will be generated, and oil cup lubrication is required on them. The other rolling guide shoe is to install the wheel on the metal frame through the bracket and rubber, and the wheel and the guide rail are rolling, with low friction and no noise.

[0003] In the prior art, the structure of the rolling guide shoe wheel is divided into: an inner bearing, a wheel sleeve in the middle, a spring connection between the bearing and the wheel sleeve, and a layer of cast shock-absorbing rubber on the outside. When the guide shoe is running, the outer layer of the shock-absorbing rubber of the wheel contacts the guide rail. Figure 1 As shown in (a), in an ideal state, the outer circle of the rubber outer ring of the wheel and the working surface of the guide rail are tangent. However, in actual situations, the guide shoe wheel has a force from the car eccentric load, such as Figure 1 As shown in (b), the rubber outer ring of the guide shoe wheel exerts a certain pressure on the working surface of the guide rail. When the elevator is in a long-term static state, the rubber is always in a compressed state. Especially after a long period of switching between high and low temperatures, the rubber of the wheel is prone to permanent deformation and cannot rebound. When the elevator starts again, every time the wheel rotates a circle to the compression deformation point, it will shake, affecting the comfort of the car. However, the period from the installation of the elevator to the use of the elevator is unpredictable. Some may be several months or even more than one or two years. In most cases, it is a relatively long period of time. For this situation, a solution is needed to prevent the rolling guide shoe from causing car comfort problems due to the deformation of the wheel rubber. In addition, if the wheel is deformed and needs to be replaced, it needs to be replaced as a whole, but the wheel sleeve is intact. Since the external rubber and the aluminum sleeve are cast as one, it is wasteful to replace the entire wheel. Utility Model Content
