Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail:
As depicted in figs. 1 and 2, a kind of elevator traction band rope sheave, including wheel body 10 and at least one grooving 20 of being provided with centre bore 110, grooving 20 is along the outer peripheral face circumference of wheel body 10, grooving 20 coordinates with traction belt, the cross section of grooving 20 is provided with the arc section 210 protruding to centre bore 110 side, and arc section 210 is positioned on same circumference.
The groove face of grooving 20 is concave circular arc type structure, when traction belt is arranged on its surface, owing to traction belt is by under tension force effect, understand automatic and grooving 20 centering, ensure the operation safety of elevator, can effectively limit traction belt to move left and right in grooving 20, traction belt is avoided to cause traction belt to misalign with grooving 20 because of installation deviation, thus the problem causing traction belt and the shoulder 220 generation friction of grooving 20 both sides, therefore the centering installation requirement of traction belt and grooving 20 is reduced, it is easily installed, and extends the service life of traction belt and rope sheave.
In the present embodiment, the radius of arc section 210 place circumference is 500mm, and grooving 20 central diameter is 100mm, and traction belt is steel band, and the material of wheel body 10 is 45 steel.According to actual needs the radius of circumference described in arc section 210 can also be set to 400mm～1000mm, grooving 20 central diameter is set to 80mm～200mm, the material of wheel body 10 is set to other materials such as Q235.
As it is shown in figure 1, grooving 20 has three, three groovings 20 are evenly arranged side by side along the axis of centre bore 110, and grooving 20 and wheel body 10 are formed in one structure.Multiple traction belts can be drawn by one rope sheave, it is ensured that traction required when elevator is properly functioning.Grooving 20 can also arrange more than one according to actual needs.
As shown in Figure 3 and Figure 4, the inner surface 250 of grooving 20 is matsurface, can be formed at the inner surface 250 of grooving 20 by the way of blasting treatment or etch processes.The inner surface 250 making grooving 20 has trickle pit 230 and protruding 240, increases the coefficient of friction between traction belt and grooving 20, it is ensured that traction required when elevator is properly functioning, eliminates lift car pier ground or the risk rushed to summit.
