Abstract
The invention discloses an elevator door change gear which comprises a groove profile used for being matched with a guide rail in a multi-point contact manner. The groove profile is used for being matched with the guide rail in the multi-point contact manner and is provided with a first side face, a second side face and a bottom face. The first side face and the second side face are located on the two sides of the bottom face so that the elevator door change gear can be in multi-point contact with the guide rail when being matched with the guide rail. Inclination generated by the elevator door change gear due to external force is avoided, interference and friction among all the parts are avoided, and the operation noise of an elevator is lowered.
Description
Technical field
The disclosure relates generally to elevator accessory, particularly relates to a kind of change spur gear of elevator door.
Background technology
At present, along with increasing of skyscraper, the use of elevator is more and more extensive, thus require also more and more higher to the change gear on elevator car door system link plate, the structure of these change gears is all be made up of core wheel and hub substantially, circumferentially arrange slot rolling at hub, the grooved of existing slot rolling is circular shape substantially, and door change gear and guide rail coordinate.When door mechanism system is subject to slight external force time, door change gear can not keep vertical, easily causes the interference between each parts of elevator interior, makes each parts produce friction, produces abnormal sound.
Summary of the invention
In view of above-mentioned defect of the prior art or deficiency, expect to provide a kind of stable change spur gear of elevator door.
Change spur gear of elevator door of the present invention, comprises grooved, and grooved is used for coordinating with guide rail Multi-contact, and grooved is provided with the first side, the second side and bottom surface, and the first side and the second side are positioned at the both sides of bottom surface.
Beneficial effect of the present invention: adopting grooved, is Multi-contact time change spur gear of elevator door is coordinated with guide rail, avoids because external force makes change spur gear of elevator door produce, and avoids producing between each parts and interferes and friction, reduce the noise that elevator runs.

Detailed description of the invention
Below in conjunction with drawings and Examples, the application is described in further detail.Be understandable that, specific embodiment described herein is only for explaining related invention, but not the restriction to this invention.It also should be noted that, for convenience of description, illustrate only in accompanying drawing and invent relevant part.
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the application in detail in conjunction with the embodiments.
Please refer to Fig. 1, a kind of change spur gear of elevator door, comprise grooved 1, grooved 1 is for coordinating with guide rail Multi-contact, and grooved 1 is provided with the both sides that the first side 12, side 11, second and side, bottom surface 13, first 11 and the second side 12 are positioned at bottom surface 13.
In an embodiment of the present invention, a kind of change spur gear of elevator door, comprise grooved 1, grooved 1 is for coordinating with guide rail Multi-contact, and change spur gear of elevator door rolls with guide rail and coordinates, when change spur gear of elevator door rolls on guide rail time, coordinate owing to adopting Multi-contact, add the stability of cooperation, elevator is run more steady, decrease fricative abnormal sound between parts.
In an embodiment of the present invention, grooved 1 is provided with the first side 12, side 11, second and bottom surface 13, first side 11 and the second side 12 are positioned at the both sides of bottom surface 13, in the process that change spur gear of elevator door coordinates with guide rail, the first side 12, side 11, second, bottom surface 13 respectively with guide rail point cantact, the first side 11 and the second side 12 are distributed in both sides, bottom surface 13, form the cooperation of three point contact, more stable, when elevator is by external force time, change spur gear of elevator door not run-off the straight.
Further, bottom surface 13 is provided with projection, and projection is used for rolling with guide rail coordinating.
In an embodiment of the present invention, bottom surface 13 is provided with projection, projection is used for rolling with guide rail coordinating, after elevator runs a period of time, owing to having friction between change spur gear of elevator door and guide rail, cause the mild wear of change spur gear of elevator door, the projection that bottom surface 13 is arranged, ensure that bottom surface 13 and guide rail are point cantact when coordinating.
With reference to figure 2, protruding cross section is arc-shaped.
In an embodiment of the present invention, protruding cross section is arc-shaped, and when projection produces wearing and tearing time, between projection and guide rail, still line coordinates, and reduces the resistance in change spur gear of elevator door operational process.
Further, contact point when projection coordinates with guide rail is positioned on the line of centers of guide rail exterior arc surface.
In an embodiment of the present invention, contact point when projection coordinates with guide rail is positioned on the line of centers of guide rail exterior arc surface, and in the normal work process of elevator, the projection mainly on change spur gear of elevator door is stressed, make change spur gear of elevator door can ensure rational loss, increase the service life of change spur gear of elevator door.
With reference to figure 3, the first side 11 for guide rail point cantact, the second side 12 for guide rail point cantact.
Further, the second contact point of the first make contact of bottom surface 13 and guide rail, the first side 11 and guide rail, the second side 12 are positioned on same circle with the 3rd contact point of guide rail.
In an embodiment of the present invention, second contact point, second side 12 of the first make contact of bottom surface 13 and guide rail, the first side 11 and guide rail are positioned on same circle with the 3rd contact point of guide rail, and it is more steady that such structure makes change spur gear of elevator door run on guide rail.
Further, grooved 1 is polyurethane grooved.
In an embodiment of the present invention, grooved 1 is polyurethane grooved, and wear resisting property is good, and mechanical strength is large.
More than describe and be only the preferred embodiment of the application and the explanation to institute's application technology principle.Those skilled in the art are to be understood that, invention scope involved in the application, be not limited to the technical scheme of the particular combination of above-mentioned technical characteristic, also should be encompassed in when not departing from described inventive concept, other technical scheme of being carried out combination in any by above-mentioned technical characteristic or its equivalent feature and being formed simultaneously.The technical characteristic that such as, disclosed in above-mentioned feature and the application (but being not limited to) has similar functions is replaced mutually and the technical scheme formed.
