Description

Anti-deviation environment-friendly general synchronous belt

Technical Field

The utility model relates to a general industrial meshing type synchronous belt drive's technical field, especially a prevent general hold-in range of environment-friendly of off tracking.

Background

In recent years, with the increasing of the manufacturing level of the china industry, the quality of basic elements of mechanical equipment is promoted to increase, and a meshing type synchronous belt transmission system applied in the industrial field is an important core element component in engineering machinery and is also greatly developed.

In the currently used meshing type synchronous belt transmission system, the grooves and the teeth of the belt wheel can be well meshed, so that the precision of power synchronous transmission is ensured, but because the tooth grooves of the belt wheel and the teeth of the synchronous belt are transverse, the transverse limiting capacity of the belt wheel on the synchronous belt is weaker, and the synchronous belt can generate a left or right deviation phenomenon along with the change of load and rotating speed in the operation process. In addition, the twill nylon elastic cloth greatly used for the tooth surface of the existing synchronous belt has a certain included angle of about 60 degrees between the warp yarns and one side of the weft yarns in the weaving process, as shown in figure 1. When the belt body is stressed in working, the nylon elastic cloth on the tooth surface is stretched, and transverse stress is generated when the nylon elastic cloth is stretched, so that the phenomenon of transverse deviation of the belt body is aggravated, a part of the synchronous belt body deviates to the outside of one side of the belt wheel, or the side surface of the belt body interferes with the flange of the belt wheel to generate the side grinding phenomenon, the running of equipment is unstable, abnormal phenomena such as shaking and noise occur, the side of the belt is damaged and the teeth are disengaged, and the service life of the synchronous belt is shortened.

Therefore, a general synchronous belt which can eliminate the transverse stress of the belt body generated by the conventional twill nylon elastic cloth product, prevent the deviation during operation and has stable operation is needed.
