Abstract
The utility model relates to a rope pulley which is used by wire ropes of hoisting machinery and equipment, mainly used for guiding and supporting the wire ropes, and is split into a rim, a spoke and a hub. The utility model is characterized in that the singly made chock-shaped rim is plugged in grooves of two webs of the spoke; in the section of the spoke, two webs are pressed into an A shape. The utility model has the advantages of no need of fastening means for the rim, free mounting or dismounting, convenient replacement, and the small self weight, the large intensity and the high stability of the pulley, and can prolong the service life of the wire ropes and the pulley.
Description
The utility model relates to a kind of rope pulley that supplies Hoisting Machinery and equipment wire rope to use, and especially relates to a kind of double width plate Combined pulley.
Rope pulley generally is used for the guiding and the supporting of crane rope, to change rope and to transmit the direction of pulling force or the pulling force of balance rope branch.
At present, the domestic pulley that a variety of patterns are arranged has Chinese patent 96241330 " inserted pulley ", and its structure is that the grooving body is embedded in the groove of wheel rim inboard, but needs to adopt fastening piece and wheel rim to be tightened to one, changes inconvenient.Other has Chinese patent 98235555 " assembling type pulley ", and its structure is that whole race is divided into trisection with the separately design of core wheel, spoke and race, and race is connected by bolt with spoke, still must fixing device, and be not easy to pulley and keep in repair.Also have some integrated type rope pulleies on the market, it takes integral manufacturing, and wheel rim need not securing means, and the spoke cross section is " I " shape, and its deficiency is from great, less stable.
The purpose of this utility model provides a kind of installation, changes double width plate Combined pulley easily.
The utility model is achieved in that pulley is divided into wheel rim, spoke, three parts of wheel hub, it is characterized in that wheel rim makes separately, is chock shape plug in the groove of two formers of spoke, two formers repressed being " A " shape in the spoke cross section.Former hole flanging section is taked interference fit with being connected of wheel hub.
The utility model has the advantages that:
1. other parts of wheel rim and pulley are not integral manufacturings, it adopts nonmetallic material, and the cross section is wedge shape, fills in the groove of two formers of spoke as chock, has self-locking action, need not any fixing device, mounting or dismounting are changed conveniently freely, after the rope race wearing and tearing are scrapped, need only change wheel rim, must not change the working life of greatly having improved wire rope and pulley by whole pulley.
2. two formers repressed being " A " shape in the spoke cross section is different from tradition " I " shape opening section, is a kind of cross section of remaining silent.Because under the same load effect, the maximum shear stress that produces on " A " tee section, constraint torsion direct stress and constraint torsional shearing stress are less than " I " shape opening section, therefore the pulley integral of " A " tee section stability and local stability are better than the pulley of " I " tee section, in addition because stress is little, cause the former thickness of pulley also to reduce, thereby reduced the deadweight of pulley.
3. former takes interference fit to be connected with wheel hub behind hole flanging, need not fixing device, has increased the convenience of equipment assembling.
Fig. 1 is a structure diagram of the present utility model.
Wheel rim 1 is the engineering plastics annulus of opening, and its cross section is wedge shape, in the groove of two formers 2 of pulley, has self-locking action with liner form plug.The outer surface of wheel rim 1 is made into to have the grooving of different wirerope diameters.
Spoke 3 is made up of the disc former 2 compacting backs of two steel.Adopt the technological method of press forming, make spoke 3 cross sections be combined into " A " shape.Form former hole flanging section 4 behind the interior aperture hole flanging of disc disc 2, engage with wheel hub 5 again.In addition, on the circumference of disc former 2, also have the rivet hole of some, by tubular-shank rivet 6 with two disc formers 2 securely riveting be integral.
Wheel hub 5 is axle sleeves of pulley, by with the interference fit of spoke former hole flanging section 4, form a whole with pulley.
Claims (2)
1. double width plate Combined pulley, it is divided into wheel rim (1), spoke (3), (5) three parts of wheel hub, it is characterized in that wheel rim (1) making separately, be chock shape plug in the groove of two formers (2) of spoke (3), two formers (2) repressed being " A " shape in spoke (3) cross section.
2. according to the described pulley of claim 1, it is characterized in that former hole flanging section (4) and being connected of wheel hub (5) taking interference fit.
