Abstract
The utility model discloses a kind of elevator traction sheave, including wheel rim, wheel rim has been bolted accessory whorl circle through first, and the accessory whorl circle includes multiple accessory whorl circle monomers, and multiple accessory whorl circle monomers are connected in series with through the second bolt；The accessory whorl circle monomer includes wheel cylinder and outer ring, takes turns and is equipped with equally distributed reinforcing rib between cylinder and outer ring, is set on each accessory whorl circle monomer there are two grooving, and grooving is interior to be equipped with bending part, and protrusion is equipped between adjacent grooving.The utility model has the advantages that replacement cost is low, traction capacity is good after service life length, damage, small to the abrasion of hoist ropes.
Description
Technical field
The utility model is related to a kind of traction sheave, especially a kind of elevator traction sheave belonging to elevator accessories field.
Background technology
Traction sheave is a part for elevator traction machine, and for carrying out the transmission of steel cable, existing traction sheave is generally integrated
The structure of formula replaces trouble and replacement cost is high if there is damage needs integral replacing, and the damage of traction sheave is typically certain
The abrasion of several groovings causes, although other groovings are intact, can also be damaged to hoist ropes, needs in time more
It changes, grooving is commonly semicircle or V-shaped at present, and semicircle grooving and hoist ropes contact area are big, but equlvalent coefficient of friction
Very little, traction capacity is low, and V-arrangement grooving both sides generate prodigious extruding, although equlvalent coefficient of friction is big, traction to hoist ropes
It restricts easy to wear.Therefore, that there are service lifes is short, replacement cost is high after damage, grooving shape causes for existing elevator traction sheave
The disadvantage that traction capacity is low, the abrasion to hoist ropes is big.
Utility model content
The purpose of the utility model is to provide a kind of elevator traction sheaves.It is replaced after having service life length, damage
Advantage at low cost, traction capacity is good, the abrasion to hoist ropes is small.
The technical solution of the utility model：Elevator traction sheave, including wheel rim, wheel rim have been bolted accessory whorl through first
Circle, the accessory whorl circle includes multiple accessory whorl circle monomers, and multiple accessory whorl circle monomers are connected in series with through the second bolt；The accessory whorl circle list
Body includes wheel cylinder and outer ring, takes turns and is equipped with equally distributed reinforcing rib between cylinder and outer ring, set on each accessory whorl circle monomer there are two
Grooving, grooving is interior to be equipped with bending part, and protrusion is equipped between adjacent grooving.
In elevator traction sheave above-mentioned, the outer ring is equipped with the first connecting hole, and wheel cylinder is equipped with the second connecting hole.
In elevator traction sheave above-mentioned, the wheel cylinder and outer ring are coaxial arrangement.
In elevator traction sheave above-mentioned, the thickness of the accessory whorl circle is more than the thickness of wheel rim.
Compared with prior art, the utility model is secondary by the way that traction sheave to be arranged to the connection structure of wheel rim and accessory whorl circle
Wheel rim again by several accessory whorl circle monomer compositions, when traction sheave damages in use, due to traction sheave grooving with drag
The action character of messenger, abrasion generally produce on certain several grooving, it is only necessary to corresponding accessory whorl circle monomer are replaced, without whole
It replaces, replacement cost is low, and service life is long, and bending is equipped in the grooving of traction sheave, and rope groove cross-section bottom is plane, and centre is equipped with
Bending part, hoist ropes are in contact with two faces of bottom plane and bending part simultaneously, and traction effect is better than common semicircle grooving, right
The abrasion of hoist ropes is smaller than common V-shaped grooving, takes into account the advantages of there are two types of groovings.Therefore, the utility model, which has, uses the longevity
The advantage that replacement cost is low, traction capacity is good after life length, damage, the abrasion to hoist ropes is small.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of accessory whorl circle monomer；
Fig. 3 is the structural schematic diagram of grooving.
Label in attached drawing be：1- wheel rims, the first bolts of 2-, 3- accessory whorl circles, 4- accessory whorl circle monomers, the second bolts of 5-, 6-
Take turns cylinder, the outer rings 7-, 8- reinforcing ribs, 9- groovings, 10- bending parts, 11- protrusions, the first connecting holes of 12-, the second connecting holes of 13-.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment：Elevator traction sheave, structure is as shown in Figures 1 to 3, including wheel rim 1, and wheel rim 1 is connected with through the first bolt 2
Accessory whorl circle 3, the accessory whorl circle 3 include multiple accessory whorl circle monomers 4, and multiple accessory whorl circle monomers 4 are connected in series with through the second bolt 5；Institute
It includes wheel cylinder 6 and outer ring 7 to state accessory whorl circle monomer 4, takes turns and is equipped with equally distributed reinforcing rib 8, each accessory whorl between cylinder 6 and outer ring 7
It is set on circle monomer 4 there are two grooving 9, grooving 9 is interior to be equipped with bending part 10, and protrusion 11 is equipped between adjacent grooving 9.
The outer ring 7 is equipped with the first connecting hole 12, and wheel cylinder 6 is equipped with the second connecting hole 13.
The wheel cylinder 6 and outer ring 7 are coaxial arrangement.
The thickness of the accessory whorl circle 3 is more than the thickness of wheel rim 1.
The mounting means and operation principle of the utility model：The assembling for completing accessory whorl circle 3 first, selects appropriate number of pair
All accessory whorl circle monomers 4 are connected by wheel rim monomer 4 with the second bolt 5, then with the first bolt 2 connection wheel rim 1 and accessory whorl circle
3, complete installation, when traction sheave has damage, the accessory whorl circle monomer 4 of damage replaced, when traction, hoist ropes simultaneously with
Two faces of bottom plane and bending part 10 are in contact, and traction effect is better than common semicircle grooving, to the abrasion of hoist ropes than general
Logical V-shaped grooving is small, and traction sheave whole service life is long, and replacement cost is low when damage.
