Abstract
A traction sheave for an elevator relates to traction sheaves, which comprises a sheave body with a central through hole. A rope race is arranged on the surface of the rim of the sheave body. The traction sheave for the elevator is characterized in that grooves identical in depth are arranged on two end faces of the sheave body respectively, reinforcing ribs are uniformly distributed between a lower step face of each groove and the sheave body, twelve auxiliary holes are uniformly arranged on the same circumference of the sheave body, and two threaded holes are symmetrically arranged on the circumference of the auxiliary holes. The weight of the traction sheave can be reduced by the aid of the grooves on the two end faces and the auxiliary holes, positioning is facilitated during production and processing by the aid of the two threaded holes which are arranged symmetrically, and the strength of the rim of the traction sheave can be enhanced. By adopting the technical scheme, the traction sheave for the elevator up to standard is simple in structure, safe, reliable and convenient in mounting and overhaul.
Description
Technical field
The utility model relates to traction sheave, and particularly the lifting mode elevator is used traction sheave.
Background technology
Elevator is a kind of comparatively complicated electromechanical integration equipment, and the traction-type cage lifter is to use the most general a kind of elevator in the vertical transportation transportation means.Towing machine is one of main mechanical part of lifting mode elevator; Rope sheave on the towing machine is called traction sheave; Be the important component part of towing machine, be installed on the towing machine turbo-shaft, have grooving on the wheel rim; Two ends hang car and counterweight (perhaps two ends are fixed on the machine room) respectively by traction steel-cable, and rely on the static friction force between steel rope and the traction sheave grooving to drive car.Therefore traction sheave is an easy-abrasion part, not only is wound with hoist ropes, and is connected with brake equipment, more complicated structurally.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, and it is convenient to install and overhaul, and practices thrift the lifting mode elevator traction wheel of cost.
The utility model comprises the wheel body that central through hole is set; Wheel rim surface at wheel body is provided with grooving; It is characterized in that being provided with respectively the groove of deep equality in the both ends of the surface of wheel body; Between the leave from office terrace of each groove and wheel body, be uniformly distributed with reinforced rib, on the same circumference of wheel body, evenly arrange 12 auxiliary holes, two tapped bore of symmetric arrangement on the circumference at said auxiliary hole place.
The utility model can reduce the own wt of traction sheave owing to be provided with two sides groove and auxiliary hole; Two tapped bore of symmetric arrangement are located when making things convenient for production and processing; The reinforced rib that is provided with can increase the traction sheave edge strength.The utility model adopts technique scheme, can make the utility model under standard compliant situation, and is simple in structure, safe and reliable, and it is convenient to install and overhaul.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the axonometric drawing of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2, the utility model comprises the wheel body 1 that central through hole 2 is set, and the diameter of central through hole 2 is 240mm, in the wheel rim surface of wheel body 1 grooving is set.
In the both ends of the surface of wheel body 1 degree of depth is set respectively and is the groove 3 that 35mm, diameter are 356mm, between each recessed 3 leave from office terrace and wheel body 1, be uniformly distributed with six reinforced ribs 6.
On the same circumference of wheel body 1, evenly arrange 12 auxiliary holes 4, also on this circumference with two tapped bore 5 of center symmetric arrangement of wheel body 1.
