The both sides of escalator are typically provided with the preventing rubber band operated together, and preventing rubber band relies on and is arranged on handrail
Revolution chain in guide rail is supported.Revolution chain is generally fixed on armrest support, and the rolling bearing of its both sides is preventing rubber
Band provides rolling support in revolution.A projection is provided among the armrest support is general, common revolution chain is arranged on this
In projection, rolling bearing is located in the groove of raised both sides, due to the needs of rolling, the bottom of rolling bearing not with groove-bottom
Portion is in contact, therefore lacks the support of bottom.When escalator runs well, preventing rubber band is applied to the revolution side roll of chain two
Power on bearing is uniform, but people are when taking elevator, and for security consideration, often handle is placed on preventing rubber band
On, it is applied with the power of multiple directions to preventing rubber band, the stress on the rolling bearing of both sides becomes uneven, or even side is stuck up
Rise, cause a certain damage for sidewindering dynamic bearing of a certain piece of revolution chained block.
Chinese utility model patent CN201620354140.3 discloses a kind of revolution chain for staircase, it is characterised in that：
The revolution chain includes at least one revolution chained block, and multiple translation mechanisms being arranged on the revolution chained block, often
The individual revolution chained block includes a bearing hole, during each translation mechanism is located in the bearing hole including one
Mandrel, a sliding bearing being set between the central shaft and bearing hole, and two be separately positioned on the central shaft
The rolling bearing at both ends, the sliding bearing are brought into close contact with the central shaft and bearing hole, the friction system of the rolling bearing
Number is less than the coefficient of friction between the central shaft and sliding bearing or between the bearing hole and sliding bearing.It is above-mentioned practical new
Type is by adjusting rolling bearing, central shaft and sliding bearing or bearing hole, the coefficient of friction of sliding bearing improves its use
Life-span, but control the coefficient of friction of above-mentioned each part complicated in actual mechanical process, the life of the revolution chain can be directly affected
Produce efficiency.At the same time, above-mentioned sliding bearing bearing hole do not carry out it is circumferentially fixed so that its own also because of frictional force and
As central shaft rolls, the abrasion to bearing hole is increased.
Utility model content
In view of the above, the purpose of this utility model is to provide a kind of new revolution chain for staircase, passes through tune
The structure of whole revolution chain axis bearing bore and bearing shell, it is ensured that the circumferentially fixed accuracy of bearing shell, and then enhance making for revolution chain
Use the life-span.
A kind of revolution chain for staircase, including at least one revolution chain element, the revolution chain element include revolution chain
Chain link and the translation mechanism being arranged on revolution chain chain link, wherein, it is provided with least one bearing on the revolution chain chain link
Hole, each translation mechanism include a central shaft being located in the bearing hole, and two are set in bearing hole both sides and are located at
Bearing shell between the central shaft and bearing hole, and two rolling bearings for being separately positioned on central shaft both sides, its feature exist
In using circumferentially fixed between the bearing shell and the bearing hole.
A kind of revolution chain for staircase provided by the utility model, which can be further arranged to the bearing shell, to be included being located in
The connecting portion of bearing hole and the carrier to be fitted with revolution chain chain link side wall, and also set up on connecting portion and worn for central shaft
The bearing shell hole crossed.
A kind of revolution chain for staircase provided by the utility model can be further arranged to the central shaft, bearing hole with
And bearing shell hole uses and is coaxially disposed.
A kind of revolution chain for staircase provided by the utility model can be further arranged to the bearing hole inwall and set
The fixing groove being outwards recessed, and the fixing groove runs through whole bearing hole, and be provided with the connecting portion of the bearing shell with fixing
The projection that groove matches.
A kind of revolution chain for staircase provided by the utility model can be further arranged to the revolution on the bearing hole
Chain chain link position is set using arc convex.
A kind of revolution chain for staircase provided by the utility model can be further arranged to the bearing shell by EPB15 engineerings
Plastic manufacturing forms.
The beneficial effects of the utility model are：
1st, between the bearing hole and bearing shell in the revolution chain chain link using circumferentially fixed, while being easy to the bearing shell to install, also
The relative movement between bearing shell and bearing hole is avoided, the circumferentially fixed structure is to be connected by the fixing groove on bearing hole with bearing shell
Projection in portion is realized, and the bearing shell uses and be fabricated with the strong EPB15 engineering plastics of self-lubricating capacities, and is adopted
With integral design so that the durability of itself of bearing shell greatly improves, and then enhances the service life of revolution chain；
2nd, the revolution chain chain link position on bearing hole is set using arc convex, it is ensured that so that bearing hole surrounding thickness
Increase, avoids the bearing bore deformation caused by stress is excessive, and then adds the service life of revolution chain.
Brief description of the drawings
Fig. 1 is a kind of revolution chain schematic diagram for staircase of the utility model.
Embodiment
A kind of revolution chain embodiment for staircase of 1 pair of the utility model is described further referring to the drawings.
This is used for the revolution chain of staircase, including at least one revolution chain element 10, and the revolution chain element 10 includes revolution
Chain chain link 20 and the translation mechanism 30 being arranged on revolution chain chain link 20, wherein, be provided with the revolution chain chain link 20 to
A few bearing hole 21, each translation mechanism 30 include a central shaft 31 being located in the bearing hole 21, and two are arranged
In the both sides of bearing hole 21 and the bearing shell 32 between the central shaft 31 and bearing hole 21, and two are separately positioned on center
The rolling bearing 33 of the both sides of axle 31, using circumferentially fixed between the bearing shell 32 and the bearing hole 21.
The bearing shell 32 includes the connecting portion 321 for being located in bearing hole 21 and fitted with revolution chain chain link 20 side wall
Carrier 322, and the bearing shell hole 323 passed through for central shaft 31 is also set up on connecting portion 321.The bearing shell 32 is by EPB15 works
Engineering plastics are fabricated.And carrier 322 is disc structure in bearing shell 32, and the disk surpasses with turning round chain chain link 20 and being bonded
Go out the Partial Resection of chain link, and avoid disk from influenceing consolidating for bearing shell 32 with rubber strip friction beyond the part of revolution chain chain link 20
It is fixed.
Circumferentially fixed form is varied, it is preferred to use the form of fixing groove 22 and projection 324, i.e., using the bearing
The inwall of hole 21 sets the fixing groove 22 being outwards recessed, and the fixing groove 22 runs through whole bearing hole 21, and in the bearing shell 32
The projection 324 to match with fixing groove 22 is provided with connecting portion 321.
Using circumferentially fixed between bearing hole 21 and bearing shell 32 in the revolution chain chain link 20, it is easy to bearing shell 32 to install same
When, it is thus also avoided that the relative movement between bearing shell 32 and bearing hole 21, the circumferentially fixed structure are by the fixation on bearing hole 21
Projection 324 on groove 22 and the connecting portion 321 of bearing shell 32 realize, and the bearing shell 32 using with self-lubricating capacities by force
