Abstract
The invention relates to a winding tension device, comprising a first semicircular shaft and a second semicircular shaft which are arranged oppositely and are rotated together; and the winding tension device is provided with a binding strip. The radii of the homolateral round angles of the first semicircular shaft and the second semicircular shaft are unequal and form a staggered high and low interval S, the radius of the round angle with long radius is larger than or equal to the thickness of the binding strip and is smaller than or equal to two times of thickness of the binding strip, the interval S is slightly more than or equal to the thickness of the binding strip, the round angle with long radius is positioned on a low point, and the round angle with short radius is positioned on a high point. The invention reduces the contact specific pressure acted on the side of the binding strip by the semicircular shafts, reduces the side shearing stress of the binding strip, and prevents the binding strip from suffering lateral shearing fracture untimely; and further more, the homolateral round angles of the two semicircular shafts form the staggered interval S, thereby improving the stress working condition of the binding strip on a second layer and enabling the invention to improve the working condition of the binding strip and to prolong the service life thereof in the premise that the cost is not increased.
Description
Technical field
The present invention relates to a kind of winding tension device.
Background technique
Winding tension device comprises two half circular shafts of facing setting and rotating together, and bundling belt is on two and half circular shafts, and when two and half circular shafts were pressed the direction rotation of straining bundling belt, bundling belt reached the object that encircling is fixed gradually around to two and half circular shafts.Present winding tension device, such as, 5 tons of winding tension devices, it mainly is to be strained and fixed on transportation process four limits for main equipment, the phenomenon that the equipment that prevents slides, tilts, collides, skews occurs.The specified tensile strength of its design is 5000daN, and 2 times safety coefficient need be arranged, and both breakdown strength will reach 10000daN.But when doing the test of complete machine Breaking strength, supporting bundling belt is broken when pulling force reaches 7800daN to 9500daN with it, and the body of winding tension device is excellent, and the tensile strength of bundling belt also reaches designing requirement through separately test.
Summary of the invention
Technical problem to be solved by this invention provides a kind of winding tension device that the bundling belt force status improves its working life that improves.For this reason, the present invention by the following technical solutions: it comprises in the face of the first half circular shafts that arrange and rotate together, the second half circular shafts, and described winding tension device is provided with the bundling belt on the first half circular shafts, the second half circular shafts; One of the radius of the homonymy fillet of described the first half circular shafts, the second half circular shafts large one little, and the height interval S of formation dislocation, the radius of the fillet that described radius is large is more than or equal to the bundling belt thickness of bundling belt thickness less than or equal to 2 times, described interval S is slightly larger than or equals the thickness of bundling belt, the fillet that radius is large is in low spot, and the fillet that radius is little is in high point; And on the sense of rotation of the first half circular shafts and the second half circular shaft tension bundling belts, the fillet that radius is little is in rear side, and the fillet that radius is large is in the front side.
By analysis, winding tension device is in when work, a side pressurized of half circular shaft, a side bending resistance, the whole transition arc of compression face and bundling belt close contact.The transition arc r of conventional winding tension device half circular shaft design both sides equates, and transition arc is generally all less than normal.Half circular shaft passes to the pulling force that the bears transition circle cambered surface by half circular shaft compression face on the bundling belt when single direction rotation, because the transition circle cambered surface is less than normal, the specific pressure that acts on the bundling belt side is just higher, thereby bundling belt is cut off easily.
Semicircle shaft section of the present invention is designed to unsymmetrical section.Fillet radius towards the pressure-bearing side is large, to increase the contact bearing area of bundling belt side, has reduced the specific contact pressure that half circular shaft acts on the bundling belt side direction, reduces the lateral shear stress of bundling belt, makes the bundling belt be unlikely to too early lateral shear fracture.And, the homonymy fillet of 2 half circular shafts forms a dislocation interval S, this spacing S is slightly larger than or equals the thickness δ of bundling belt, like this, the profile that the first layer that forms twines bundling belt seamlessly transits, improved the force status of second layer bundling belt, made the present invention can be under the prerequisite that does not increase cost, improve bundling belt force status, improve its working life.
Description of drawings
Fig. 1 is embodiment's provided by the present invention schematic representation.
Embodiment
With reference to accompanying drawing.The present invention includes in the face of the first half circular shafts 1 that arrange and rotate together, the second half circular shafts 2, described winding tension device is provided with the bundling belt 3 on the first half circular shafts, the second half circular shafts; One of the radius of the homonymy fillet of described the first half circular shafts, the second half circular shafts large one little, and the height interval S of formation dislocation, the radius of the fillet that described radius is large is more than or equal to the bundling belt thickness of bundling belt thickness δ less than or equal to 2 times, described interval S is slightly larger than or equals the thickness δ of bundling belt, the fillet 4 that radius is large is in low spot, the radius of fillet 4 is expressed as R, and the fillet 5 that radius is little is in high point, and the radius of fillet 5 is expressed as r; And on the sense of rotation D of the first half circular shafts and the second half circular shaft tension bundling belts, the fillet that radius is little is in rear side, and the fillet that radius is large is in the front side.
Described the first half circular shafts, the second half circular shafts are connected on the ratchet 6, the spin axis of the first half circular shafts, the second half circular shafts is coaxial with the spin axis of ratchet, winding tension device fluctuates to stir ratchet one-way rotation by handle, thereby drive two and half circular shaft single direction rotations, with the bundling belt that is through the industrial dacron thread braiding between two and half circular shafts around to two and half circular shafts, the object that tension is fixed.
Above embodiment all only gives an example for convenience of description, is not the restriction to protection scope of the present invention.For those skilled in the art, under the situation that does not break away from spirit of the present invention and scope, the variation of making all is within protection scope of the present invention.
