Description
Technical field
The present invention relates to escalator chain field, specifically refers in particular to a kind of major-minor wheel type step chain bar.
Background technology
With the extensive use of escalator, the exploitation of escalator is also increasing, therefore each escalator manufactory
Competition between family is also growing more intense；For the needs of competition, producer optimizes in the design of escalator one after another.Staircase
On step chain also accordingly and then optimize together.
At present, the structure of the step chain of automatic escalator of all multi-vendor designs uses major-minor wheel according to the reason for stress size
With reference to structure, this structure type greatly reduces purchase cost, selected in global design have during chain it is obvious competing
Strive advantage.
The content of the invention
A kind of major-minor wheel type step chain bar is provided the invention aims to overcome the deficiencies in the prior art.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of major-minor wheel type step chain bar is by multiple chain links
Composition is sequentially connected, each chain link includes inner plate and sleeve；The inner plate has two, parallel and be arranged at intervals, and both ends
Inner side is respectively equipped with sleeve；The both sides of the abutting end of the adjacent link are respectively equipped with axle carrier bar, outer plate, and adjacent link
One end of connection passes through corresponding inner plate, axle carrier bar, outer plate and sleeve by short pin shaft, and the other end is passed through corresponding by long pin shaft
Inner plate, axle carrier bar, outer plate and sleeve, realize the connection of adjacent link；It is spaced between the adjacent long pin shaft two short
Bearing pin；Accessory whorl is arranged with the sleeve at the short pin shaft；Main wheel is arranged with sleeve at the long pin shaft.
Preferably, the inner plate, axle carrier bar and outer plate are 45 steel.
Preferably, described short pin shaft one end is fixed for die, and the other end is fixed for back-up ring.
Preferably, fixed on the outside of the long pin shaft by back-up ring.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
Major-minor wheel type step chain bar of the present invention takes major-minor wheel construction Combination Design, reduces the production cost of manufacture,
And there is obvious competitive advantage in the global design of staircase producer is selected.

Short pin shaft 3；Described one end of short pin shaft 3 is that die 4 is fixed, and the other end is that back-up ring 5 is fixed；Sleeve 9 at the short pin shaft 3
On be arranged with accessory whorl 7；The outside of long pin shaft 6 is fixed by back-up ring 5, and is arranged with main wheel 8 on the sleeve 9 at long pin shaft 6；
The inner plate 1, axle carrier bar 10 and outer plate 11 are 45 steel.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
Major-minor wheel type step chain bar of the present invention takes major-minor wheel construction Combination Design, reduces the production cost of manufacture,
And there is obvious competitive advantage in the global design of staircase producer is selected.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, it should all cover within the scope of the present invention.
