Abstract
The invention discloses a kind of elevator promotion steel bands, it is by multistrand rope and each wirerope is wrapped up integral wrapping layer forms, it is characterized in that, the cross-sectional shape for promoting steel band is trapezoidal, short side in trapezoidal two parallel edges is the bottom edge for promoting steel band, is in contact with traction sheave slot bottom, promotes the two sides of steel band as guide surface, for the automatic centering of steel band, and angle of wedge φ≤45 ° that two sides are constituted.The invention also discloses the traction races to match with above-mentioned promotion steel band, it is characterised in that: the shape of traction race is matched with the cross-sectional shape of the promotion steel band.
Description
Technical field
The present invention relates to elevators field, especially a kind of elevator is prevented with steel band and its matching used traction race is promoted
Only there is sideslip in elevator steel band.
Background technique
Currently, more and more elevator traction liftings start the effect for replacing wirerope using steel band.But promote steel
Band is easy left and right migration sideslip, so that vibration of elevator and generate noise, the also aggravation abrasion that promotes steel band.Cope with the mode of sideslip
Have very much: traction sheave being such as made into drum type, but the internal stress with intermediate position will be caused to be greater than two sides in this way, causes steel
Band Central Cracking；For another example Chinese patent 200810061529.9 is made to change in shape, increases multiple dispersions in steel band
Discontinuous protrusion is concave surface (or use V-ribbed belt) between each protrusion, also correspondingly production male and fomale(M&F) and promotes steel on race
The protrusion of band and concave surface matching use, although also can effectively realize the guiding for promoting steel band, the critical defect of this structure is just
It is to cause the coefficient of friction of promotion steel band and race larger, promoting steel band can not skid.How to guarantee that promoting steel band uses the longevity
Under the premise of life, the automatic centering of steel band is realized, be still to be worth the problem of inquiring into.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of elevator promotes steel band and its traction race, it can
Under the premise of guaranteeing to promote steel band service life, steel belt deviation is prevented.
To achieve the above object, specific technical solution is: a kind of elevator promotes steel band by multistrand rope and will be each
Wirerope wraps up integral wrapping layer composition, which is characterized in that the cross-sectional shape for promoting steel band be it is trapezoidal, this is trapezoidal
Short side in two parallel edges is the bottom edge for promoting steel band, is in contact with traction sheave slot bottom, and the two sides for promoting steel band, which are used as, leads
To face, for the automatic centering of steel band, and angle of wedge φ≤45 ° that two sides are constituted.
The invention also discloses the traction races to match with above-mentioned promotion steel band, it is characterised in that: the shape of traction race
Shape is matched with the cross-sectional shape of the promotion steel band.
Preferably, the shape of traction race be it is trapezoidal, slot bottom size than promotion steel band bottom edge size it is 0.5MM big with
On.
Further, the groove angle of traction race is ψ, ψ≤φ.
The configuration of the present invention is simple, the manufacturing cost for promoting steel band and traction sheave are relatively low, and can not only realize promotion
Steel band automatic centering guarantees to promote steel band even running in traction race, avoids the deviation phenomenon of promotion steel band, but also changes
The kind stress for promoting steel band, prolongs its service life, while reducing vibration and noise.
Detailed description of the invention
Figure 1A, Figure 1B are the cross-sectional view and perspective view that elevator of the present invention promotes steel band respectively；
Fig. 2 is the cooperation figure that the present invention promotes steel band and traction sheave.
Specific embodiment
In the following, based on attached drawing, embodiments of the present invention will be described.
As shown in figure 1 a or figure 1b, the present invention is that a kind of elevator promotes steel band 10, by multistrand rope 12 arranged side by side with
And each wirerope is wrapped up into integral wrapping layer 11 and is formed, wrapping layer 11 is rubber, plastics or other composite materials.Its feature
Be: it is described promoted steel band 10 cross-sectional shape be it is trapezoidal, the short side d in trapezoidal two parallel edges be promotion steel band bottom
Side is in contact with traction sheave slot bottom, promotes the two sides b of steel band as guide surface, for the automatic centering of steel band, and two
Angle of wedge φ≤45 ° that side b is constituted.
As shown in Fig. 2, feature exists the invention also discloses the traction race 20 to match with above-mentioned promotion steel band 10
In: the shape of traction race 20 is matched with the cross-sectional shape of the promotion steel band 10.
Preferably, the shape of traction race 20 be it is trapezoidal, slot bottom size than promotion steel band bottom edge size it is 0.5MM big with
On.
Further, the groove angle of traction race 20 is ψ, ψ≤φ.
The configuration of the present invention is simple, the manufacturing cost for promoting steel band and traction sheave are relatively low, and can not only realize promotion
Steel band automatic centering guarantees to promote steel band even running in traction race, avoids the deviation phenomenon of promotion steel band, but also changes
The kind stress for promoting steel band, prolongs its service life, while reducing vibration and noise.
The present invention is not limited to the above embodiment, and cannot be enumerated, it is all using the design method that has been pointed out of the present invention or
Person's mentality of designing is considered as within protection scope of the present invention.
Claims (4)
1. a kind of elevator is with promoting steel band by multistrand rope and each wirerope is wrapped up integral wrapping layer form, special
