Abstract
The utility model relates to a novel elevator traction sheave which comprises a flat-plate-shaped body and rims. The rims are arranged on the edges of the body in circles and in continuous mode, the rims are perpendicular to the flat plane of the body, and an axial concentric wheel barrel is arranged in the center of the body. The novel elevator traction sheave is characterized in that an outer rim is arranged on the outer side of each rim in a circle in coaxial and sleeved mode, rope grooves are arranged on the outer surface of each outer rim, the rope grooves extend along the circumferential direction of each outer rim, and the axial rope grooves at different positions on each outer rim are sequentially connected in head-tail mode to form a spiral rope groove group. According to the novel elevator traction sheave, the multiple spiral rope groove groups are arranged on the outer rims, a single traction rope is wound more than two circles, and therefore the contact area and the static friction force of the traction rope are enlarged, and transmission is enabled to be more stable and safer. The outer rims can be sleeved outside the rims and connected with the rims through screw threads, under the premise that the connection between the outer rims and the rims are firm and stable, the outer rims can be conveniently dismounted and replaced, and therefore the service life of the novel elevator traction sheave is prolonged.
Description
Technical field
The utility model relates to the traction sheave in a kind of elevator power plant, relates in particular to a kind of traction sheave with grooving.
Background technology
The power plant of elevator mainly is towing machine, specifically comprises electrical motor, drg, coupler, drop-gear box, traction sheave and frame.Wherein, traction sheave also claims the traction rope sheave or drives rope sheave, is the device that elevator transmits traction power, utilizes the friction force transferring power of grooving on traction steel-cable and the traction wheel rim, is contained on the worm-wheel shaft in the retarder.At present, circumferential grooving on the traction sheave, separate between the two adjacent rings, usually drive the lift car lifting with several one by one corresponding hoist ropes that are arranged in the individual pen grooving, the area of contact of single hoist ropes and grooving is little, easily skid and skid off, affect normal traction work, even cause danger.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provides a kind of simple in structure, and transmission of power is more stable, safety, the novel elevator traction sheave of long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel elevator traction sheave, comprise the tabular body and be located at continuous wheel rim of described one week of body edges, described wheel rim is perpendicular to body plane, body center is provided with axial nebenkern cylinder, it is characterized in that: the described wheel rim outside one all coaxial sleeves are provided with the outer rim that outside face is laid grooving, and described grooving circumferentially extends along outer rim, and the grooving of the axial diverse location of outer rim is curl grooving group from beginning to end in turn.
In preferred embodiment of the utility model, comprise that further described outer rim is threadedly connected on the wheel rim.
In preferred embodiment of the utility model, comprise further on the described outer rim that diverse location is provided with 1-5 described grooving group vertically.
In preferred embodiment of the utility model, further comprise comprising 2-3 circle grooving in described each grooving group.
In preferred embodiment of the utility model, further comprise being provided with successively vertically 5 described grooving groups on the described outer rim.
In preferred embodiment of the utility model, further comprise comprising 3 circle groovings in described each grooving group.
In preferred embodiment of the utility model, the bottom surface that further comprises described every circle grooving perpendicular to outer rim axial be projected as annulus.
The utility model has solved the defective that exists in the background technology, and elevator traction sheave of the present utility model arranges many group spiral fashion groovings at outer rim, and single hoist ropes twines more than 2 circles, enlarge active surface and static friction force, more stable transmission and safety.Outer rim can be set in outside the wheel rim in the mode that is threaded, guarantee under the prerequisite of firm stable, the facility of provide dismounting, changing, prolongation traction sheave service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the cutaway view of preferred embodiment of the present utility model;
Among the figure: 2, body, 4, wheel rim, 6, the wheel cylinder, 8, outer rim, 81, grooving, 10, the fixed position.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of novel elevator traction sheave of the present utility model, comprise tabular body 2 and be located at continuous wheel rim 4 of described body one week of 2 edges, described wheel rim 4 is perpendicular to body 2 planes, body 2 central authorities are provided with axial nebenkern cylinder 6, described wheel rim 4 outsides one all coaxial sleeves are provided with the outer rim 8 that outside face is laid grooving 81, and described grooving 81 circumferentially extends along outer rim 8, and the grooving 81 of outer rim 8 axial diverse locations is curl grooving group from beginning to end in turn.Described outer rim 8 is connected by screw, nut with two pairs of fixed positions 10 of wheel rim 4 in body 2 both sides, and described two pairs of fixed positions 10 are about body 2 plane symmetry, and the line of every pair of two fixed positions 10 is parallel to body 2 planes.Be provided with successively vertically 5 described grooving groups on the described outer rim 8, comprise 3 circle groovings 81 in each grooving group.The bottom surface of described every circle grooving 81 perpendicular to outer rim 8 axial be projected as annulus, the width of every circle grooving 81 circumferential optional positions is identical, each grooving width that encloses grooving 81 is also identical; The degree of depth of every circle grooving 81 circumferential optional positions is identical, and each grooving degree of depth of enclosing grooving 81 is also identical.Less than 1/2 of individual pen grooving 81 width, outer rim 8 thickness are greater than 1.3 times of arbitrary grooving 81 degree of depth along the axial distance of wheel rim 4 for 81 of each groovings.
During use, by in the spiral-shaped embedding grooving 81 of corresponding grooving group, an end is connected with car with every hoist ropes, and the other end and to reconnecting, traction sheave utilize the friction force between itself and hoist ropes, and the drive hoist ropes drives the car lifting then.Because same hoist ropes will be walked around 3 circle groovings 81, grooving 81 bottom surfaces have increased the area of contact of hoist ropes with 81 of groovings greatly with radian in addition, increase friction force, be difficult for producing bad slip, in addition certain grooving degree of depth, can improve the stability of traction sheave work, strengthen safety.According to grooving 81 width, with the distance of 81 of groovings arrange less, less than 1/2 of individual pen grooving 81 width, be conducive to reduce hoist ropes moment that two ends produce in the grooving group, the minimizing harmful effect.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification sheets, must determine technical scope according to the claim scope.
