Detailed description of the invention
Below embodiment of the present utility model is described in detail:
As shown in Figure 1 and Figure 2, a kind of hand rail band guiding device, including support frame the 10th, support shaft 20 and double-row balls
Bearing 30, described double-row bearing 30 is arranged on the outside of described support shaft 20, and described support shaft 20 is arranged on described support
On framework 10, described support frame 10 is internal for the handrail guide rail 200 being arranged at handrail 100 turn-around zone, described
Double-row bearing 30 is for contacting with the inner surface of handrail 100.Wherein, described handrail 100 turn-around zone refers to automatically
The upper R portion of handrail 100 running orbit of staircase or moving sidewalk or lower R portion.In the present embodiment, described support shaft 20 is pin
Axle, uses general part as support shaft 20, simple in construction, low cost of manufacture.Described support frame 10 is for supporting steel band, and structure is steady
Gu.Described support frame 10 and described handrail guide rail 200 can by being welded to connect or bolt the mode such as is connected and realizes connecting,
Connect reliable.
When described hand rail band guiding device uses, support frame 10 is arranged on the handrail at handrail 100 turn-around zone
Band guide rail 200 is internal, makes described double-row bearing 30 contact the fortune of supporting armrests band 100 with the inner surface of handrail 100
OK, frictional force at this turn-around zone for the handrail 100 is become rolling friction from sliding friction, and handrail 100 turns to district at this
The running resistance in territory reduces.Further, owing to a support shaft 20 is provided with a double-row bearing 30, i.e. a support shaft
On 20, the roller of supporting armrests band 100 is unique, there are not two rollers mutually by the problem such as side force, poor synchronization.Described
During hand rail band guiding plant running, will not produce mutual side force, synchronism is good, rotation is flexible, can effectively reduce handrail
With the running resistance of 100, eliminate the play phenomenon that handrail 100 runs, it is ensured that passenger's boarding safety.
Further, described support frame 10 includes base plate 110 and is arranged on the side plate 120 of described base plate 110 both sides,
The installing space of described support shaft the 20th, the double-row bearing 30 of formation receiving between described base plate 110 and side plate 120, described
The two ends of support axle 20 are separately mounted on the side plate 120 of respective side.Described support frame 10 is for along handrail 100 moving direction
Strip, described support shaft 20 is multiple, and described double-row bearing 30 corresponds to multiple, and multiple support shaft 20 is along handrail
100 moving direction intervals are arranged in described support frame 10, multiple double-row bearings 30 shape in described support frame 10
Become roller support bar.As in figure 2 it is shown, after the hand rail band guiding device described in the present embodiment is arranged on handrail guide rail 200, energy
Enough one roller support bars of formation at handrail 100 turn-around zone, and then effectively reduce the fortune in turn-around zone for the handrail 100
Row resistance.
As shown in Figure 1, Figure 3, described double-row bearing 30 includes outer ring body the 310th, inner ring body 320 and double rolling
Pearl body 330, described double-row balls body 330 is arranged between described outer ring body 310 and described inner ring body 320, described
Inner ring body 320 is arranged on outside described support shaft 20, and described outer ring body 310 is for contacting with the inner surface of handrail 100.
By using said structure, double-row bearing 30 can either realize the support to handrail 100, again can be as support shaft 20
Upper unique roller, it is to avoid produce the problem such as side force, poor synchronization in handrail 100 running, rotates flexibly, can
Effectively reduce the running resistance of handrail 100, eliminate the play phenomenon that handrail 100 runs, it is ensured that passenger's boarding safety.
In the present embodiment, described double-row bearing 30 is equipped with sealing ring 40, energy along the two sides of its axis direction
Enough play water proof and dust proof effect, strengthen the service life of described double-row bearing 30.Further, owing to have employed double-row balls axle
Hold 30, handrail 100 running will not produce side force, and then sealing ring 40 also will not produce lateral gap, seal
Property is good, can increase the service life of described double-row bearing 30 further.
The described hand rail band guiding device of this enforcement, by using the double-row bearing 30 with two row's balls, one
The double-row bearing 30 of one sole support handrail 100 is set in root support shaft 20, conventionally employed two can be prevented effectively from
Mutually by the problem such as side force, poor synchronization during individual roller.During described hand rail band guiding plant running, mutual side will not be produced
Xiang Li, synchronism are good, rotation is flexible, can effectively reduce the running resistance of handrail 100, eliminate altering of handrail 100 operation
Dynamic phenomenon, it is ensured that passenger's boarding safety, and service life is long.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality
The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited
It in contradiction, is all considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the common skill of this area
