Abstract
A lifting elevator traction sheave with a rope groove relates to a traction sheave, in particular to a lifting elevator traction sheave. The utility model discloses a set up the wheel body of central through-hole, set up the grooving on the rim surface of wheel body, its characterized in that the shape of grooving sets up the arc transition face respectively for having the semicircular of incision at two semicircular tip, the incision is located the bottom at semicircular center. The utility model discloses a grooving shape sets up to semi-circular incision, and existing V-arrangement groove equivalent friction coefficient is big advantage, has the half slot again and can make wire rope warp the advantage that freedom, contact surface are big.
Description
Technical field
The utility model 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 purpose of the utility model 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 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 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 grooving shape of the utility model 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 said kerf angle of the utility model is 35 °.
The utility model is simple in structure, and is safe and reliable, and it is convenient to install and overhaul.
Description of drawings
Fig. 1 is a kind of axonometric drawing of the utility model.
Fig. 2 is put scheme drawing greatly for a grooving of the utility model.
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.
