Set so that every reinforcement can be mutually coordinated so that the intensity of whole rope sheave body is preferable.
Preferably, the open top width that described two inclined walls are formed is the open top width of circular-arc bottom face
4/5ths.The open top width that two inclined walls are formed is suitable with the diameter of traction steel-cable, the specific setting of width,
Both enabled traction steel-cable it is suitable be placed and taken out annular groove, in turn ensure that traction steel-cable in the course of the work will not
Deviate from easily out of annular groove, ensure that the safety of work.
Preferably, it is provided with bearing holder (housing, cover) in the centre bore.The setting of bearing holder (housing, cover) enables to diversion sheave on center shaft
It is more flexible to rotate.
Preferably, it is provided with yielding rubber circle in the bearing holder (housing, cover).When car starts or stopped suddenly suddenly, subtract
Shake the active force for alleviating diversion sheave and center between centers that rubber ring can be suitably so that the service life of diversion sheave and central shaft is all
It is elongated.
The present invention has the advantages that：
(1) it is circular-arc bottom face to be arranged to bottom by the groove at by rope sheave body outline, and both sides are inclined wall
Annular groove structure so that annular groove be internally formed bottom circular arc A/F be slightly larger than top necking width
Degree, security are higher；
(2) by the way that the shape that section is arc surface will be arranged at the top of reinforcement so that the intensity of whole rope sheave body compared with
It is high；By setting counterbore, the wall of counterbore is arranged to round and smooth arcwall face, and the counterbore of rope sheave body both sides is interconnected, made again
The radiating effect for obtaining rope sheave body is preferable；
(3) by setting bearing holder (housing, cover) in centre bore, to cause the rotation of diversion sheave on center shaft more flexible；Pass through
Set yielding rubber circle to carry out the appropriate active force for alleviating diversion sheave and center between centers in bearing holder (housing, cover), extend diversion sheave and center
The service life of axle.
