Abstract
The invention provides a kind of novel large height public traffic type escalator step chains roller shock absorption device, comprise step chain and ladder sprocket wheel, described step chain has roller and is located at the chain sheet of roller both sides, described roller is meshed with the teeth groove of ladder sprocket wheel, the both sides of described ladder sprocket wheel are respectively equipped with the non-metal roller supporting described chain sheet, described non-metal roller can be arranged on described ladder sprocket wheel along self axial rotation, between described roller and the teeth groove of described ladder sprocket wheel, there is gap when described chain sheet is supported on described non-metal roller.Compared to prior art, the present invention's dismounting supports the chain sheet of step chain by the non-metal roller be arranged on ladder sprocket wheel, make, between the roller of step chain and the teeth groove of ladder sprocket wheel, there is gap, roller can not strike the teeth groove of ladder sprocket wheel, thus reach the effect of damping and minimizing impact noise, simple for structure, easy accessibility.
Description
Technical field
The present invention relates to a kind of step chains roller shock absorption device of escalator.
Background technology
The structure that large height public traffic type escalator step chains generally adopts main wheel external, in order to reduce the collision of roller and ladder sprocket wheel, general employing carries out damping at ladder sprocket wheel inside embedding rubber pad, but the replacing of rubber pad is cumbersome.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of easy for installation, damping effect is better, changes the step chains roller shock absorption device of simple large height public traffic type escalator.
For achieving the above object, the invention provides a kind of novel large height public traffic type escalator step chains roller shock absorption device, comprise step chain and ladder sprocket wheel, described step chain has roller and is located at the chain sheet of roller both sides, described roller is meshed with the teeth groove of ladder sprocket wheel, it is characterized in that: the both sides of described ladder sprocket wheel are respectively equipped with to support the non-metal roller of described chain sheet, described non-metal roller can be arranged on described ladder sprocket wheel along self axial rotation, between described roller and the teeth groove of described ladder sprocket wheel, there is gap when described chain sheet is supported on described non-metal roller.
Preferably, the rotary centerline of described non-metal roller parallels with the rotary centerline of described ladder sprocket wheel.
More preferably, the quantity of the non-metal roller of the both sides of described ladder sprocket wheel is multiple, is distributed on described ladder sprocket wheel along same circumference uniform intervals at the multiple described non-metal roller of the same side.
Further, at the multiple described non-metal roller of the same side and the teeth groove one_to_one corresponding of described ladder sprocket wheel, and each described non-metal roller is all located at the radially inner side of corresponding teeth groove along described ladder sprocket wheel.
Wherein, described non-metal roller is arranged on the both sides of described ladder sprocket wheel by axle and jump ring.
More preferably, the non-metal roller one_to_one corresponding on the both sides of described ladder sprocket wheel, and corresponding two non-metal rollers are arranged on the both sides of described ladder sprocket wheel by the axle that same runs through described ladder sprocket wheel.
Owing to adopting technique scheme, the present invention has the following advantages: step chain is through ladder sprocket wheel, the chain sector-meeting of step chains first rolls across from non-metal roller, support due to non-metal roller makes step chain height slightly raise, between roller and the teeth groove of ladder sprocket wheel, there is gap, roller can not strike the teeth groove of ladder sprocket wheel, is replaced the collision of metal and metal by the collision of non-metal and metal, thus reaches damping and reduce the effect of impact noise; Because non-metal roller is the both sides being fixed on ladder sprocket wheel by axle and jump ring, simple for structure, easy accessibility.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention is arranged on equipment.
Fig. 2 is the enlarging section, A portion in Fig. 1.
Fig. 3 is the installation distribution graph of non-metal roller of the present invention on ladder sprocket wheel.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Refer to Fig. 1 to Fig. 3, a kind of novel large height public traffic type escalator step chains roller shock absorption device of the present invention, comprise step chain and ladder sprocket wheel 4, described step chain has roller 7 and is located at the chain sheet of roller both sides, the chain sheet of every side comprises outer chain sheet 5 and inner chain sheet 6, roller 7 is meshed with the teeth groove 41 of ladder sprocket wheel 4, the both sides of ladder sprocket wheel 4 are respectively equipped with the non-metal roller 1 supporting described chain sheet, non-metal roller 1 can be arranged on ladder sprocket wheel 4 along self axial rotation, between roller 7 and the teeth groove 41 of ladder sprocket wheel 4, there is gap when described chain sheet is supported on non-metal roller 1.Non-metal roller 1 is arranged on the both sides of ladder sprocket wheel 4 by axle 3 and jump ring 2.
Refer to Fig. 3, in the present embodiment, the rotary centerline of non-metal roller 1 parallels with the rotary centerline of ladder sprocket wheel 4.The quantity of the non-metal roller 1 of the both sides of ladder sprocket wheel 4 is multiple, is distributed on ladder sprocket wheel 4 along same circumference uniform intervals at multiple non-metal rollers 1 of the same side.
At multiple non-metal rollers 1 of the same side and the teeth groove one_to_one corresponding of ladder sprocket wheel 4, and each non-metal roller 1 is all located at the radially inner side of corresponding teeth groove 41 along ladder sprocket wheel 4.
In the present embodiment, axle 3 runs through ladder sprocket wheel 4, non-metal roller 1 one_to_one corresponding on the both sides of institute's ladder sprocket wheel 4, and corresponding two non-metal rollers 1 are arranged on the both sides of described ladder sprocket wheel by axle 3 and fix respectively by jump ring 2.
When escalator operation, step chain is when ladder sprocket wheel 4, step chains outer chain sheet 5 and/or step chains inner chain sheet 6 can first roll across from non-metal roller 1, because the step chain height that makes of non-metal roller 1 is slightly raised, roller 7 can not strike the teeth groove 41 of ladder sprocket wheel 4, replaced the collision of metal and metal by the collision of non-metal and metal, thus reach damping and reduce the effect of impact noise.Non-metal roller 1 can be the material such as rubber or resin.
Because non-metal roller 1 is the both sides being arranged on ladder sprocket wheel 4 by axle 3 and jump ring 2, simple for structure, dismounting is very convenient, and maintenance cost is lower.
