Drive rope sheave and bear the hawser load all the time, require the function that when tractive force takes place, is well on and rotates.For this reason, drive rope sheave and must have sufficient hardness and intensity, need high-precision processing.For from the big elevator moment of torsion of drive motor transmission, drive that rope sheave adopts the method for hot pressing or key etc. and chimeric with S. A. securely again.Therefore, traditional driving rope sheave is made of thick-wall high-strength casting thing, has hindered the miniaturization and of Winch for elevator.
Again, when adopting the main rope that is made of the steel hawser, from the flexibility equal angles of steel hawser, require D/d (driving rope sheave diameter/main rope diameter) more than 40, this point also can make and drive the rope sheave maximization.
To this, realized the main rope that constitutes by synthetic fibre rope in recent years.This synthetic fibre rope is good because of having high coefficient of friction and pliability, so D/d can be reduced to about 25, can make to drive the rope sheave miniaturization.
Yet particularly when using the high-capacity winch of large-scale Winch for elevator, because of the diameter of S. A. is thicker, in a single day so reduce to drive the diameter of rope sheave, the difference that drives the diameter of the diameter of rope sheave and S. A. is dwindled.That is, when reducing to Min. as if the diameter that will drive rope sheave, driving rope sheave becomes thin-walled, is difficult to drive the manufacturing of rope sheave, is not easy to embed S. A..Therefore,, might influence the miniaturization that drives rope sheave from making and the stack-mounted angle, and then the miniaturization and of restriction winch.
