Problems solved by technology

Since the sprocket has many tooth grooves, the installation workload of this structure is large, and it needs to be processed in each tooth groove, which is inconvenient to process, and the installation error of multiple vibration damping pads will also cause inconsistent meshing height and large meshing vibration

Embodiment Construction

[0030] Such as Figure 1 to Figure 2 As shown, the driving sprocket used in the passenger conveying device of the present invention includes a vibration-damping sprocket 1, a reinforcing sprocket 2, and a fastener 3 for connection. The vibration-damping sprocket 1 is directly engaged with the rollers of the step chain, The meshing is stable, so as to achieve the effect of vibration reduction and noise reduction; one side or both sides of the vibration reduction sprocket 1 is fixed with a reinforced sprocket 2, and the reinforced sprocket 2 is used to ensure the strength of the sprocket; the vibration reduction sprocket 1 Mounting holes are respectively opened on the reinforced sprocket 2, and are fixed into a whole by axial connection and fixing of multiple fasteners 3 arranged in the mounting holes, so as to meet the load requirements of high lifting height and heavy-duty public transportation occasions;

[0031] The shape of the sprocket of the damping sprocket 1 is designed...

Abstract

The invention discloses a driving chain wheel for a passenger transportation device. The driving chain wheel comprises vibration reducing chain wheels, reinforced chain wheels and fastening parts; the reinforced chain wheels are fixedly arranged on single sides or two sides of the vibration reducing chain wheels; mounting holes are respectively formed in the vibration reducing chain wheels and the reinforced chain wheels, and the vibration reducing chain wheels and the reinforced chain wheels are axially connected and fixed as a whole through multiple fastening parts arranged in the mounting holes; the shapes of the reinforced chain wheels are matched with the shapes of the vibration reducing chain wheels; the bottoms of tooth grooves of the reinforced chain wheels are lower than the bottoms of tooth grooves of the vibration reducing chain wheels; and the two sides of the tooth grooves of the reinforced chain wheels are aligned to or slightly higher than the two sides of the tooth grooves of the vibration reducing chain wheels. The driving chain wheel is simple in structure, convenient for disassembly and assembly, easy to guarantee the matching precision after installation and capable of guaranteeing stable engagement between chains and chain wheels, guarantees the strength, and can be applied to heavy-load public transportation places.

Description

technical field [0001] The invention relates to an accessory of a passenger conveying device, in particular to a driving sprocket for a passenger conveying device. Background technique [0002] Larger vibration and noise will be generated by the meshing of the chain and the sprocket in the driving station of the escalator or moving walk, and in the slewing station. In order to overcome this defect, the following two technologies are generally used at present: [0003] One is to use all-steel sprockets, place the step chain rollers between the inner and outer sides of the chain, and the rollers made of non-metallic materials mesh with the steel sprockets. However, due to the limitation of the diameter of the step chain roller itself, the bearing in the step chain roller cannot bear a large force, so this structure cannot adapt to the occasions of high lifting height or heavy-duty public transportation. [0004] The other is to use a steel sprocket, and add damping pads or d...
