Embodiment Construction

[0017] Hereinafter, technical solutions in the embodiments of the present invention will be clearly and completely described. Apparently, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts will fall within the protection scope of the present invention.

[0018] figure 1 with 2 An example of a roller for an escalator or moving walk according to the present invention is shown, the roller includes a bearing 1, a hub 2, a polyurethane rim 3, and the bearing, the hub, and the outer ring are coaxial. The bearing 1 includes rolling elements 11 , a cage 12 , an inner ring 13 of the bearing 1 , and an outer ring 14 of the bearing 1 . The outer ring 14 of the bearing 1 is integrated on the hub 2 and becomes a part of the hub, and the rolling elements 11 are generally balls.

Abstract

The invention discloses a roller wheel for an escalator or a moving sidewalk and a manufacturing method thereof. The roller wheel is composed of a bearing capable of rotating around a roller wheel rotating shaft, a hub wrapping the bearing and a rim wrapping the hub, and the bearing is composed of a rolling body, a retainer, an inner ring and an outer ring, wherein the inner ring and the outer ring are made of thermoplastic materials, the outer ring of the bearing is integrated on the hub, and the outer ring of the bearing and the hub are of an integrated structure. During manufacturing, the polyurethane rim is firstly subjected to injection molding, then the bearing inner ring and the hub are subjected to injection molding at the same time, in the process, the polyurethane rim and the hubare welded together, and finally the polyurethane rim and the hub are pressed into the rolling body and the retainer. The problem that an existing roller wheel bearing for the escalator or the movingsidewalk rusts is solved, and the roller wheel cost is reduced.

Description

technical field [0001] The present invention relates to escalators or moving walks. More specifically, the present invention relates to a roller for an escalator or moving walk and a method of manufacturing the same. Background technique [0002] Escalators or moving walks are widely used in shopping malls, airports, subways and other occasions with large passenger flow. Rollers are important load-bearing parts on escalators, usually including polyurethane rims, polyamide hubs and rolling bearings, and heavy-duty occasions such as subways also include metal hubs. Rolling bearings include metal outer rings, metal inner rings, rolling elements, cages, etc. While metal bearings reduce friction, they also introduce rust problems, increasing the weight and cost of the rollers. The existing plastic bearings on the market can solve the rust problem, but the plastic bearings cannot be put into the mold to inject the hub, because the high temperature environment in the mold will d...
