Abstract
The utility model relates to an elevator, and particularly to an elevator door machine. An elevator door belt pulley transmission assembly comprises a poly V-belt wheel, a synchronous belt wheel and a fixing device. The poly V-belt wheel is connected with the synchronous belt wheel. The synchronous belt wheel is connected with the fixing device. The fixing device is provided with a bearing. The inner diameter of the connection part between the fixing device and the bearing is larger than the outer diameter of the bearing. The inner diameter of the left side and the right side of the connection part between the fixing device and the bearing is not larger than the outer diameter of the bearing. As the technical solution is adopted, the fixing device of the utility model is closely connected with the bearing and is not shaken easily, so the elevator door belt pulley transmission assembly has the following advantages: reliable safety, simple structure, higher stability, etc.
Description
Technical field
The utility model relates to elevator, is specifically related to elevator door closing mechanism.
Background technique
In the modern life, elevator applications is very extensive.Elevator door closing mechanism is used to control a servo-system that opens and closes elevator door, is the important component part of elevator.The elevator door closing mechanism kind is a lot of in the market, and elevator door closing mechanism adopts the belt pulley transmission usually, and the assembly in the belt pulley transmission adopts poly Vbelt wheel, synchronous pulley and fixing device mostly, and fixing device is provided with bearing, and each assembly interacts and plays transmission agency.
Being connected of existing fixed device and bearing exists connection not tight, and loosening easily, Security and stability are not strong yet, have influenced the normal operation of elevator door closing mechanism like this.
The model utility content
The purpose of this utility model is, provides a kind of elevator door belt pulley transmitting assemblies, to solve the problems of the technologies described above.
The technical problem that the utility model solved can realize by the following technical solutions:
Elevator door belt pulley transmitting assemblies, comprise poly Vbelt wheel, synchronous pulley and fixing device, described poly Vbelt wheel is connected with described synchronous pulley, described synchronous pulley is connected with described fixing device, described fixing device is provided with bearing, the internal diameter of described fixing device and bearing joint is greater than the external diameter of described bearing, and the internal diameter of described fixing device and bearing joint the right and left is not more than the external diameter of described bearing.By above-mentioned design, the tight socket of fixing device and bearing is stuck in bearing in the fixing device so firmly, and difficult generation is rocked.
When fixing device of the present utility model is connected with bearing, adopt principle of expanding with heat and contracting with cold, earlier fixing device heated, treat the internal diameter expansion of fixing device after, overlap upper bearing (metal) in predetermined bearing and fixing device joint, allow the fixing device natural cooling then.After the fixing device cooling, the internal diameter of fixing device almost or fully returns to original size, and fixing device well compresses bearing, is difficult for like this producing rocking.
Described poly Vbelt wheel is provided with at least one penetrating post hole, can save material, weight reduction like this.The shape in penetrating post hole can be cylindrical, also can be other shapes.
Beneficial effect: owing to adopted technique scheme, the utility model fixing device is connected closely with bearing, is difficult for rocking, and makes to the utlity model has advantages such as safe and reliable, simple in structure, that stability is stronger.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model fixing device and the sectional view that is connected of bearing.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
The technical problem that the utility model solved can realize by the following technical solutions:
With reference to Fig. 1, Fig. 2, elevator door belt pulley transmitting assemblies, comprise poly Vbelt wheel 1, synchronous pulley 2 and fixing device 3, poly Vbelt wheel 1 is connected with synchronous pulley 2, synchronous pulley 2 is connected with fixing device 3, fixing device 3 is provided with bearing 4, and the internal diameter of fixing device 3 and bearing 4 joints is greater than the external diameter of bearing 4, and the internal diameter of fixing device 3 and bearing 4 joint the right and lefts is not more than the external diameter of bearing 4.By above-mentioned design, fixing device 3 and bearing 4 tight sockets are stuck in bearing 4 in the fixing device 3 so firmly, and difficult generation is rocked.When fixing device 3 of the present utility model is connected with bearing 4, adopt principle of expanding with heat and contracting with cold, earlier fixing device 3 heated, treat the internal diameter expansion of fixing device 3 after, at predetermined bearing 4 and fixing device 3 joints cover upper bearing (metal) 4, allow fixing device 3 natural cooling then.After fixing device 3 coolings, the internal diameter of fixing device 3 almost or fully returns to original size, and fixing device 3 well compresses bearing 4, is difficult for like this producing and rocks.
Poly Vbelt wheel 1 is provided with at least one penetrating post hole 11, can save material, weight reduction like this.The shape in penetrating post hole 11 can be cylindrical, also can be other shapes.Adopt cylindrical penetrating post hole among Fig. 1.General penetrating post hole 11 is set to around a plurality of penetrating post hole 11 in the center of circle of poly Vbelt wheel 1.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
