Description
Technical field
The present invention relates to staircase field, more particularly to a kind of self-lubricating staircase turns round chain.
Background technology
Escalator, also referred to as handrail elevator are a kind of means of transports transporting people in a manner of conveyer belt.Escalator is general
It is tilting, the step of pedestrian's automatically walk in an end station of staircase will be brought to the other end of staircase, on the way step automatically
It can keep horizontal all the way.Compared with elevator, escalator takes up space more, and the action speed of vertical direction is relatively very
Slowly, but because escalator is continuous action, passenger will wait cabs to arrive unlike as elevator, therefore total handling capacity of passengers of staircase
It is much higher therefore more common in the big place of the flows of the people such as market, subway.
The both sides of escalator are typically provided with the preventing rubber band operated together, and preventing rubber band, which relies on, is mounted on handrail
Revolution chain in guide rail is supported.Revolution chain is generally fixed on armrest support, and the rolling bearing of both sides is preventing rubber
Band provides rolling support in revolution.
Chinese patent ZL200980158025.1 discloses the armrest assembly using roller bearing, using returning for rolling bearing
Turn chain, handrail will produce a large amount of abrasive dust and dust with rail friction, and abrasive dust and dust can cause to roll after entering rolling bearing
Dynamic bearing clamping stagnation or rail damage and fail, the staircase of outdoor operation can cause to get rusty because rainwater enters rolling bearing.
Chinese patent ZL201020002044.5 discloses a kind of self-lubricating plastic stairway rotary chain, plastic sliding bearing
Fixed, two side wheels drive axis pin to rub in plastic sliding bearing, and the pressure that handrail is brought on chain idler wheel is hung down forever
Directly in chain link direction, cause axis pin that the mill that friction causes plastic sliding bearing occurs in the same side of plastic sliding bearing forever
Damage, the service life that plastic sliding bearing wall thickness has worn chain just finish.
