Abstract
The utility model discloses a metal rope wheel formed by punching, splitting and spinning, and turning a single steel plate. The metal rope wheel comprises a rope slot, a wheel circular ring and a bearing room, wherein the bearing room is arranged on an inner periphery; a bearing station is arranged on the bearing room; and an arc station having the same axis with the bearing room is arranged on the wheel circular ring. One end of the arc station is connected with the periphery of one end of the bearing room, and the other end of the arc station is ended at the surface of the wheel circular ring. By arranging the arc station on the wheel circular ring, the bearing room is formed through punching, meanwhile, the tensile strength and the yield stress of the metal rope wheel are increased, therefore, under the condition that the tensile strength and the yield stress are identical, the material thickness can be reduced, and the cost is saved; furthermore, the arc station is formed by directly punching, so the processing is convenient; the production efficiency is obviously improved; and the wheel quality is easy to ensure.
Description
Technical field
The utility model relates to the rope sheave that uses in a kind of elevator door.
Background technology
Rope sheave is the vitals that uses in the elevator door, the common rope sheave that has plastics, metallic material to make, and be used for elevator industry rise draw rope sheave since to performance requriementss such as tensile strength, yield stresses than higher, so generally use metal rope sheave.The method for making that Chinese patent application specification sheets CN101327562A discloses a kind of metallic rope pulley on December 24th, 2008, the metallic rope pulley of making according to this kind method comprises annulus, ring is provided with bearing carrier ring in this annulus, this bearing carrier ring one end is made by punching press, the other end is by being welded, the excircle of annulus is provided with grooving, and grooving to the annulus between bearing carrier ring is the plane, and bearing is housed in the bearing carrier ring.This metallic rope pulley is thicker, and materials are many, otherwise is difficult to satisfy the requirement of elevator to tensile strength and yield stress, and cost is than higher; But also needing welding, processing is inconvenient.
The utility model content
The purpose of this utility model is to provide that a kind of materials are few, intensity is high, beat, shake little metallic rope pulley.
For achieving the above object, the technical solution adopted in the utility model metallic rope pulley, it comprises grooving, wheel annulus and bearing chamber, described bearing chamber is arranged on the inner periphery of wheel annulus, one end of bearing chamber is provided with bearing stand, it is characterized in that the described annulus of taking turns is provided with arc platform with the bearing chamber concentric.
As the further qualification of this programme, the other end periphery of described arc platform one end and bearing chamber joins, and the other end ends on the wheel circular planes.
Described grooving, wheel annulus, bearing chamber are formed through punching press, the spinning of riving, turning by the monolithic steel plate.
Employing is provided with the scheme of arc platform on anchor ring, the tensile strength and the yield stress of metallic rope pulley have been increased, at identical tensile strength and the next thickness that can reduce materials of yield stress, provide cost savings, as do not have the metallic rope pulley of arc platform need expect thick 3mm, only need 2.5mm after having adopted the arc platform; Simultaneously the arc platform of this programme is by directly being stamped to form, and is easy to process, production efficiency and and safety factor be significantly improved the easier assurance of the quality of wheel.
Description of drawings
Fig. 1, front view of the present utility model;
Fig. 2, be the A-A cutaway view of the utility model front view shown in Figure 1.
The specific embodiment
As Fig. 1, shown in Figure 2, metallic rope pulley of the present utility model is made of wheel annulus 2 and bearing chamber 4, excircle on the wheel annulus 2 is provided with grooving 1, this grooving 1 can be the class V-slot, 2 inner periphery of wheel annulus is provided with the bearing chamber 4 that is stamped to form, one end of bearing chamber 4 is provided with bearing stand 5, the promising arc platform 3 of the outer periphery of the other end, this arc platform 3 is an integral body with annulus, makes by punching press, one end arises from the bearing chamber outer rim, the other end ends on the circular planes, and bearing is embedded in the bearing chamber 4, fixes by calling the roll in the morning in the arc platform side of bearing chamber, for easy to use, the arc platform can be a little more than bearing.
The utility model does not limit to and the above-mentioned specific embodiment, all drops in the protection domain of the present utility model so long as be provided with the metallic rope pulley of arc platform on the anchor ring of bearing chamber outer rim.
Claims (3)
1. metallic rope pulley, it comprises grooving, wheel annulus and bearing chamber, and described bearing chamber is arranged on the inner periphery of wheel annulus, and an end of bearing chamber is provided with bearing stand, it is characterized in that, and the described annulus of taking turns is provided with arc platform with the bearing chamber concentric.
2. according to the described metallic rope pulley of claim 1, it is characterized in that the other end periphery of described arc platform one end and bearing chamber joins, the other end ends on the wheel circular planes.
