Description

The messenger chain that has sliding sleeve
The present invention relates to a kind of messenger chain, this messenger chain especially can be used for escalator or moving sidewalk.In this application, carry the step of escalator or the supporting plate of moving sidewalk by messenger chain.This messenger chain is for example open by DE 4334064A1.
In the chain joint of this known messenger chain, connecting panel was right in two interior connecting panels connected into by sleeve.This sleeve is run through by master track pin, and it is right that this master track pin connects into outside link plate with two outside link plates.Two connecting panels are to pivoting relative to each other on this chain joint.But, a sliding bearing sleeve is set, and sleeve and master track pin are made by special material and the design of electroplated coating ground between sleeve and master track pin for this pivotability of assurance in long-time.
The messenger chain of escalator and moving sidewalk is continuous endless chain, and its starting point and terminal point at feedway turns on sprocket wheel.At this, the driving of chain also realizes by the engagement of chain and driving chain wheel.Sprocket wheel has the breach of appropriate moulding, so the protection roller place of sprocket wheel in the chain joint area catch chain, and then chain since sprocket rotation by transmission.At this, the change of the direction of load and size can influence master track pin and sleeve.Fig. 5 shows scheme drawing, so that understand described problem.When the chain linear running; because load to be transmitted for example obtains at master track pin shown in Fig. 5 left side, that have sleeve 101 (illustrating as common cylinder) and protects the relative position of roller 102; wherein, obviously show the gap of expression eccentric distance e large at this.Even if pad is provided with a sliding sleeve between protection roller and sleeve, that is be equipped with the sliding sleeve that is pressed into or sleeve 101 when being equipped with the sliding sleeve that presses when the protection roller, this same relative position also arranged protecting between roller and the sleeve.Obtained at the relative position shown in Fig. 5 the right during with sprocket wheel 103 engagements at protection roller 102, just sleeve 101 reduces apart from e and impact protector roller downwards or is positioned at wherein plain bearing.This has produced noise.
The details that relative position changes between the master track pin and sleeve when sleeve and sprocket engagement has for example been described in WO 01/42122, wherein, the document is corresponding has put down in writing a kind of like this technical solution, promptly, make the such degree of cyclic irregularity of having rotatablely moved of sprocket wheel, make that thus when producing impact in the chain, the velocity contrast between sprocket wheel and the chain is always minimum.
Technical matters to be solved by this invention is a kind of messenger chain that is particularly useful for escalator and moving sidewalk of suggestion, and this messenger chain produces little running noises.
The messenger chain of the feature of technical matters of the present invention by having claim 1 solves.In each dependent claims, put down in writing favorable structure of the present invention.
According to the present invention; by having master track pin by movable, that by connecting panel the chain link of forming is formed relative to each other messenger chain; the connecting panel that it is right that this master track pin will be formed connecting panel interconnects and runs through the sleeve setting movably; rotatable protection roller of this sleeve supporting; and described messenger chain has a sliding sleeve that is clamped between sleeve and the protection roller, the off-centre offsetting between this sliding sleeve permission sleeve and the protection roller.
Can avoid free clearance between sleeve, sliding sleeve and the protection roller by this structure of sliding sleeve.Sliding sleeve is filled the circular gap between sleeve and the protection roller, but however also allows the longitudinal axis of sleeve mobile a little prejudicially with respect to the longitudinal axis of protection roller.This means that sliding sleeve both also contacted with the protection roller with sleeve.Therefore can avoid sleeve and protect roller with sprocket engagement the time because the load conversion is especially being moved through free clearance (described gap) collision or impact relative to each other afterwards.Because the impact noise that collision produces can be avoided by use the described sliding sleeve that bears load by the present invention, described chain moves tranquillyer.
