Description
Technical field
The present invention relates to the elevators of a kind of lift facility manufacturing field more particularly to a kind of drawing belt and the cooperation drawing belt
Traction sheave.
Background technology
Existing elevator generally use one or more and steel wire rope that cross-sectional shape is rounded as connection car
With the transmission parts of counterweight, that is, the stiction between steel wire rope and traction sheave is relied on to realize the oscilaltion of car and counterweight.
There is relatively cheap strong point using simple steel wire rope as transmission parts, but due to the friction between steel wire rope and traction sheave
The phenomenon that contacting and show as tangent contact, thus being also easy to produce traction deficiency or even have skidded.Grooving on traction sheave is set
Cross-sectional shape is calculated as in V shapes or the semicircle traction that can improve steel wire rope, it might even be possible to avoid causing because of skidding
Passive motion artifacts, but the abrasion of steel wire rope and traction sheave can significantly aggravate, and influence the adequate service life of steel wire rope.Directly
Connect is using another drawback of exposed steel wire rope：Due to needing in a manner of time-based maintenance to steel wire rope supplemental lubrication grease, because
And lubricant grease, which is used for a long time, on the one hand influences traction efficiency, that is, influences the transmission of the traction of steel wire rope, it is on the other hand easily right
Elevator shaft generates pollution.
In particular, according to elevator design regulation, the diameter ratio of traction sheave and steel wire rope is not less than 40: 1, then if steel wire
A diameter of 8-10 ㎜ of rope, then a diameter of 320-400 ㎜ or more of traction sheave and according to elevator design regulatory requirements, steel wire
The diameter of rope does not allow to be less than 8 ㎜.Then, steel wire rope and rope sheave（Traction sheave, guide wheel, elevator cage guide wheel and counterweight guide wheel
It is referred to as rope sheave）Between forgoing relationship be difficult to even make the volume of rope sheave towards the desired miniaturization hair of industry
Exhibition, because the volume for reducing rope sheave can reduce the overall cost of elevator and reduce the occupancy to space.
In order to overcome above-mentioned technical problem, occurs a kind of drawing belt now to replace steel wire rope, but in the daily of elevator
In operational process, those skilled in the art have found, a group or more of drawing belts on traction sheave will appear shift phenomenon, when going out
When now deviating, the drawing belt that other groups are working normally will receive interference, to be easy to cause the unstable of elevator lifting, hold
Easily lead to security risk.Further, since drawing belt is generally flat structure, steel wire strand can not be possessed as steel wire rope and twined
The larger intensity brought after, thus its service life is generally shorter, needs often to overhaul.
