Abstract
The utility model relates to an eccentric pressure pulley which comprises a base, an eccentric shaft, a pressure pulley body and a bearing. The lower end of the eccentric shaft is installed inside the base in a coaxial and embedded mode. The pressure pulley body is installed in the eccentric portion of the upper end of the eccentric shaft in a coaxial and sleeved mode. The bearing is installed between the pressure pulley body and the upper portion of the eccentric shaft in a coaxial and sleeved mode. According to the eccentric pressure pulley, an eccentric structure design is adopted, installation angles of the eccentric pressure pulley only need to be adjusted to achieve the purpose of adjusting pretightening force of a synchronous belt in the step of debugging the pretightening force of the synchronous belt in the productive process, and a tool for debugging the pretightening force of the synchronous belt is saved. The synchronous belt can be deformed and lengthened after the synchronous belt is used for a period of time. The installation angles of the eccentric pressure pulley only need to be adjusted to achieve the purpose of adjusting the pretightening force of the synchronous belt, and debugging time is effectively saved.
Description
Technical field
The utility model belongs to the video protection and monitor field, relates to guide pulley, especially a kind of eccentric guide pulley.
Background technique
The general mode that adopts band transmission synchronously in the drive mechanism of The Cloud Terrace, but the pretightening force of band transmission synchronously affects the reliability and the transmission accuracy of The Cloud Terrace always.
Regulate synchronously that the method for band pretightening force generally is to regulate synchronous band pretightening force by the centre distance of regulating between driving wheel and the follower, generally in the process of debugging, need to use special-purpose frock, not only raise the cost but also reduce working efficiency.
In addition, reliable in order to guarantee synchronous tape running, usually cooperate guide pulley is installed, but traditional guide pulley is generally concentric structure, especially after synchronous tape running is than the long time, belt can be out of shape elongation, thereby the centre distance that must regulate driving wheel and follower guarantees the pretightening force of band synchronously, and the shortcoming of this adjustment pretightening force method is: 1, adjustment work is very loaded down with trivial details; 2, expend great amount of manpower.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, rational eccentric guide pulley of design science is provided.
Technical solutions of the utility model are achieved in that
A kind of eccentric guide pulley comprises pedestal, eccentric shaft, guide pulley, bearing, the coaxial lower end that is embedded with eccentric shaft in the described pedestal, and the upper end eccentric part coaxial package of this eccentric shaft has guide pulley, and coaxial package has bearing between the top of guide pulley and eccentric shaft.
And described pedestal links together by three screws of radial equipartition and the underpart of eccentric shaft, and the upper end portion of this eccentric shaft is coaxially installed with nut.
And described bearing is two, and coaxial spaced is installed between the top and guide pulley of eccentric shaft.
Advantage of the present utility model and good effect are:
1, this eccentric guide pulley adopts the eccentric structure design, be with in the link of pretightening force synchronously in the production process debugging, only need can realize adjusting the purpose of synchronous band pretightening force by the setting angle of adjusting eccentric guide pulley, save the debugging frock of band pretightening force synchronously.
2, band can be with distortion to elongate in use for some time synchronously, and a setting angle that needs to adjust eccentric guide pulley can be adjusted the purpose that realizes adjusting synchronous band pretightening force, effectively saves debug time.
3, the utility model design science is reasonable, simple in structure, easy to operate, not only reduces cost, and effectively increases work efficiency.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is a structure sectional view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of eccentric guide pulley, comprise pedestal 4, eccentric shaft 3, guide pulley 2, bearing 6, the coaxial lower end that is embedded with eccentric shaft in the described pedestal, the upper end eccentric part coaxial package of this eccentric shaft has guide pulley, and coaxial spaced is set with two bearings between the top of guide pulley and eccentric shaft.
In the present embodiment, as shown in Figure 2, the top of described eccentric shaft and the axis runout of bottom.
Described pedestal links together by three screws 5 of radial equipartition and the underpart of eccentric shaft, and the upper end portion of this eccentric shaft is coaxially installed with nut 1.
