Abstract
The invention relates to a traction wheel, and particularly relates to an elevator traction wheel with a rope groove. The elevator traction wheel comprises a wheel body provided with a central through hole, and a rope groove is arranged on the surface of the rim of the wheel body. The elevator traction wheel is characterized in that the rope groove is a semicircular groove with a notch, two end parts of the semicircle are respectively provided with an arc transitional surface, and the notch is positioned at the bottom of the semicircle center. According to the invention, the rope groove is arranged to be the semicircular groove with the notch, so that the elevator traction wheel in the invention not only has the advantage of large equivalent coefficient of friction of a V-shaped groove but also has the advantage of a semicircular groove capable of causing free deformation and large contact surface of a steel wire rope.
Description
Technical field
The present invention really relates to a kind of traction sheave, particularly a kind of lifting mode elevator traction wheel.
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 true purpose of the present invention provide a kind of can provide have certain coefficient of friction, simple in structure, install and maintenance has the lifting mode elevator traction wheel of grooving easily.
The present invention really 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 shaped as of said grooving has the semicircle of otch, in semi-round two ends arc transiting surface is set respectively, said otch is positioned at the bottom at semicircle center.
The true grooving shape of the present invention is set to semi-circular cut-out, and the big advantage of existing V-shaped groove equlvalent coefficient of friction has half slot can make the advantage that the steel rope distortion is free, contact surface is big again.
For reaching best result of use, the true said kerf angle of the present invention is 35 °.
The present invention is really simple in structure, and is safe and reliable, and it is convenient to install and overhaul.
Description of drawings
Fig. 1 is the true a kind of axonometric drawing of the present invention.
Fig. 2 is put scheme drawing greatly for a true grooving of the present invention.
The specific embodiment
As shown in Figure 1, in the wheel rim surface of the wheel body 1 of central through hole some groovings 2 are set.
As shown in Figure 2, each grooving 2 is shaped as the semicircle 2-1 with otch 2-2, in two ends of semicircle 2-1 arc transiting surface 2-3 and 2-4 is set respectively.Otch 2-2 is positioned at the bottom at semicircle 2-1 center, and kerf angle is 35 °.
Claims (2)
1. the lifting mode elevator traction with grooving is taken turns; Comprise 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 shaped as of said grooving has the semicircle of otch, in semi-round two ends arc transiting surface is set respectively, said otch is positioned at the bottom at semicircle center.
2. according to the said lifting mode elevator traction wheel of claim 1, it is characterized in that kerf angle is 35 ° with grooving.
