The contact pressure of wire ropes which are wound around the sheave or that on the roller has an important effect upon the durability of wire ropes. We have carried out a series of studies on the contact pressure of the wire rope, and reported some results of them, when the wire rope was bent by a small angle by the cast iron or the lining roller.
In this paper is reported the result of studies made experimentally and theoretically on the contact pressure of wire ropes which are wound around the cast iron or the lining sheave.
The result can be summarized as follows:
(1) The contact pressure of wire ropes on cast iron sheaves can be calculated from Q/d²-A_c/μνd² curve.
(2) With larger diameter of the sheave, the contact pressure decreases in the case of the lining sheave.
(3) The contact pressure of wire ropes which are wound around the lining sheave is nearly equal to that of the wire ropes on the lining roller for the angle of the deviation 2α=6°.
(4) The contact pressure of the wire ropes which are bent by a small angle by the lining roller can be obtained, if values calculated by Herz's formula are multiplied by a compensation factor based on the construction of the wire rope.
