Description
Technical field
The utility model belongs to elevator technology field, and in particular to a kind of ladder sprocket wheel of escalator.
Background technology
Escalator is widely used in the public places such as market, station, subway, for continuative transport personnel.Ladder sprocket wheel
It is the important component for driving and carrying passenger on staircase.Ladder sprocket wheel on general staircase is molded by plastics and metal rolling bearing
Molding, cost is higher, and rolling bearing is connect with step axis pin, and friction therebetween is larger, serious wear.Ladder sprocket wheel is run
On guide rail, carry step and passenger it is necessary to have good elasticity, provide buffering, damping effect, relax so as to improve to take
Adaptive reduces noise.Existing ladder sprocket wheel is made of hard material, can meet bearing requirements, but cause without elasticity
Buffering, the effect of damping are poor, and the riding comfort of passenger is poor.
The information for being disclosed in the utility model background technology part is merely intended to deepen the general background to the utility model
The understanding of technology, and be not construed as recognizing or imply in any form the information form by those skilled in the art public affairs
The prior art known.
Utility model content
The purpose of this utility model is to provide a kind of ladder sprocket wheels of escalator, and gold is replaced using plastic sliding bearing
Belong to rolling bearing, there is low friction and anti abrasive performance.
In addition, the utility model has good buffering and damping effect, and step can be mitigated by engraved structure
The overall weight of sprocket wheel can save material, mitigate weight, further save cost.
The purpose of this utility model is achieved through the following technical solutions：
A kind of ladder sprocket wheel of escalator, including wheel body, the center of the wheel body is equipped with to install step axis pin
Step bearing pin mounting hole is fixedly provided with plastic sliding bearing in the step bearing pin mounting hole, the plastic sliding bearing
The deep equality of length and the step bearing pin mounting hole, step axis pin are tightly sleeved in the plastic sliding bearing；It is described
It is engraved structure between the periphery of wheel body and the step bearing pin mounting hole, and the periphery of the wheel body and the step axis pin
Flexible more damping ribs are set between mounting hole.
Preferably, the more damping ribs are along the circumferential direction radially arranged.
Preferably, two damping ribs are one group of triangle rib group, the vertex of the triangle rib group
It is set close to the step bearing pin mounting hole, multigroup triangle rib group is along the circumferential direction set at equal intervals.
Preferably, the damping rib and the wheel body by integral forming.
Preferably, the wheel body and the damping rib by polyformaldehyde material or polyamide resin material integrated injection molding into
Type.
The beneficial effects of the utility model are：
The utility model replaces metal rolling bearing using plastic sliding bearing, has low friction and anti abrasive performance,
And cost can be reduced；In addition, the utility model by setting damping rib, can play good buffering and damping effect
Fruit；And the overall weight of ladder sprocket wheel can be mitigated by engraved structure, material can be saved, mitigate weight, further save
Cost-saving.

Specific embodiment
With reference to specific embodiment and respective drawings, the utility model is described in further detail.
It is to be appreciated that appended attached drawing is not proportionally drawn, and merely to illustrating the basic principle of the utility model
Various features the suitably simplified technique of painting.The specific design feature of the utility model disclosed herein includes for example specific ruler
Very little, direction, position and shape will be partly determined by the specific application and use environment.
In appended multiple attached drawings, same or equivalent component (element) is indexed with identical reference numeral.
As shown in Figure 1 to Figure 3, the ladder sprocket wheel of the escalator described in the utility model embodiment, including wheel body 1, wheel
The center of body 1 is equipped with the step bearing pin mounting hole for installing step axis pin, is fixedly provided with plastics in step bearing pin mounting hole
Sliding bearing 2, the length of plastic sliding bearing 2 and the deep equality of step bearing pin mounting hole, step axis pin, which is tightly sleeved, to be moulded
Expect in sliding bearing；It is engraved structure between the periphery of wheel body 1 and step bearing pin mounting hole, and the periphery of wheel body 1 and step
Flexible more damping ribs 3 are set between bearing pin mounting hole.
In this example, wheel body 1 is with damping rib 3 by polyformaldehyde material or polyamide resin material integrated injection molding.
Metal rolling bearing is replaced using plastic sliding bearing, plastic sliding bearing has low rub by injection molding
The anti abrasive performance of scrape along, and cost can be reduced.
Damping rib have certain elasticity, be capable of providing when sprocket wheel is run buffering, damping effect, multiply so as to improve
Comfort is sat, reduces noise, and wheel body and damping rib be by polyformaldehyde material or polyamide resin material integrated injection molding,
Can have damping and anti abrasive performance simultaneously.
By the engraved structure of wheel body, material can be saved, mitigates weight, further saves cost.
In this example, the more damping ribs 3 are along the circumferential direction radially arranged.
In this example, two damping ribs 3 are one group of triangle rib group, and the vertex of triangle rib group is close to step
Bearing pin mounting hole is set, and multigroup triangle rib group is along the circumferential direction set at equal intervals.
In this example, it is equidistantly provided with 16 groups of triangle rib groups.
Wherein two damping ribs are arranged to triangular shaped damping and support construction for one group, by triangular shaped
It can play the role of good supporting role, and damping rib has good buffering and damping in itself.In ladder sprocket wheel
During operation, the structure formed by multigroup triangle rib group can have enough support strengths, and with good bullet
Property, provide buffering, damping effect, so as to improve riding comfort, reduce noise.
The front description that specific illustrative embodiment is presented to the utility model is for the purpose of illustration and description.
The description of front, which is not intended to become, to be not intended to the utility model is limited to disclosed accurate shape without missing
