A kind of driving belt is from tensioning mechanism
Technical field
The utility model relates to driving belt technical field, utilizes motor to conduct oneself with dignity specifically and makes a kind of driving belt of driving belt tensioning from tensioning mechanism.
Background technique
At present, along with the development of society, to the mechanization of process equipment, the requirement of hommization is also more and more higher.Conventional driving belt tensioning mechanism, implements to force tensioning to driving belt, and when power of enforcement is spent greatly easily, easily make transmission device wear and tear, dynamics is too small, causes transmission efficiency low; In addition, force tension device be easily subject to external or inherent problems affect and lost efficacy, cause driving belt transmission efficiency to change.
Model utility content
The purpose of this utility model is to provide a kind of driving belt from tensioning mechanism, utilizes motor to conduct oneself with dignity and implements driving belt tensioning in the course of the work in good time.
For achieving the above object, technical solution adopted in the utility model is:
A kind of driving belt is from tensioning mechanism, and the driving belt that it comprises motor, is connected with motor, described motor is arranged on motor cabinet, and described motor cabinet is connected on support by rotating shaft, and described motor cabinet is also provided with balancing weight.
As further improvement of the utility model, described support is provided with limit stoper.
In the utility model, motor cabinet is rack-mount by rotating shaft, and motor cabinet can around axis of rotation, when driving belt works, make driving belt auto-tensioning by the deadweight of motor, when motor deadweight is inadequate, motor cabinet increases balancing weight, makes driving belt tensioning.When driving belt ruptures, motor cabinet falls on support, prevents contingency from occurring.
The utility model utilizes motor and balancing weight to make driving belt auto-tensioning in the course of the work, and avoid and force tension device to the harmful effect of driving belt, the utility model structure is simple, easy to use.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of driving belt is as shown in Figure 1 from tensioning mechanism, and the driving belt 6 that it comprises motor 5, is connected with motor 5, motor 5 is arranged on motor cabinet 3, and motor cabinet 3 is connected on support 1 by rotating shaft 2, and motor cabinet 3 is also provided with balancing weight 4.Support 1 is provided with elevator mechanism.
By support 1 lifting, after installing driving belt 6, progressively reduce support 1, make driving belt 6 tensioning by the deadweight of motor 5, when relaxation phenomenon appears in driving belt 6, motor cabinet 3 increases balancing weight 4 gradually, the Zhang Jindu of adjustment driving belt 6.
The utility model structure is simple, easy to use.
