Description

The elevator traction suspension gear
Technical field
The utility model relates to the drag device that a kind of article promote, and specifically is a kind of elevator lifting traction suspension gear that is used for.
Background technology
The elevator traction suspension gear of the present upper and lower motion of drive lift car is suspended on for steel rope in the grooving of traction sheave, and the radius of curvature of steel rope bending is identical with the radius of traction sheave.For reducing the endurance failure that steel rope is in the repeated flex state for a long time, according to GB7588-2003 " elevator manufacturing with safety standard is installed ", wirerope diameter is necessary 〉=8mm, traction sheave and wirerope diameter are than necessary 〉=40.Big traction sheave diameter needs big moment just can make the upper and lower motion of car, thereby significantly increases the manufacturing cost of towing machine.The elevator of installing for no machine room also can increase hoistway and take up room simultaneously, thereby increases building cost.With the traditional approach of steel rope as drawing belt, core body has appearred with the outer platypelloid type drawing belt of high friction, wear resistant rubber-plastics material and the flat drawing belt that one side has serrated slot of coating of many seizing wires for a change.But 1. for the former, drawing belt on traction sheave and transition wheel because processing and installation deviation can cause end float misalignment, serious even may cause many drawing belts overlapping or interfere with each other.For avoiding the generation of this kind phenomenon, a kind of traction sheave has appearred, and be the circular arc projection in the middle of it, the chord length of its arc of while should be 1.5~2.25 times of bandwidth.Can increase the axial length of traction sheave so greatly, thereby increase the amount of deflection of traction sheave when heavy duty.And usually traction sheave and axle are made of one, will add large-diameter for reducing sag of axle, will increase the traction sheave diameter like this, adopt the advantage of belt traction, thereby promptly can reduce the advantage that traction moment reduces the towing machine manufacturing cost thereby partly lost.2. for the latter, one side have the flat drawing belt of serrated slot to require on traction sheave, to process and with the serrated slot respective saw teeth, limit the end float misalignment of drawing belt on traction sheave.But when the guide wheel of drawing belt by car and balance counterweight because the drawing belt back side is smooth flat, just might be on guide wheel end float misalignment, thereby cause interfering with each other of many drawing belts, even overlapping.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of and can reduce the towing machine manufacturing cost, avoids drawing belt to produce the elevator traction suspension gear of end float misalignment on guide wheel.
For solving the problems of the technologies described above, the elevator traction suspension gear that the utility model provides, comprise and have traction sheave, drawing belt, guide wheel, described drawing belt comprises that heart yearn, one side have the clad of protruding I, described heart yearn is positioned within the clad, and the groove on described protruding I and the traction sheave matches.The another side of the clad of described drawing belt has several protruding II, and the groove with protruding II profile coupling is arranged on the described guide wheel.
After adopting above structure, owing to designed projection at the another side of drawing belt clad, and the profile of projection is complementary with the shape of the groove on the guide wheel, so avoided the end float misalignment of drawing belt on guide wheel.Also need not increase simultaneously the axial length of traction sheave, promptly need not increase the diameter of traction sheave, thereby reduce the manufacturing cost of elevator traction machine.
As further improvement, the top width of the groove on the described guide wheel is greater than the bottom width of protruding II on the drawing belt, and the bottom width of described groove is greater than the top width of described protruding II, and the degree of depth of described groove is greater than the height of described protruding II.After adopting this structure, it is lighter that protruding II on the drawing belt is cooperated with groove on the guide wheel, thereby make the operation of lift car more steady.
As further improving, the shape of cross section of the protruding II on the described drawing belt can be trapezoidal, can be rectangle, can also be semicircle or triangle.Adopt such structure, make drawing belt and Guiding wheel structure and processing simpler.
