In today's life, the use of timing belts is becoming more and more common. It can be found in large equipment such as machine tools and automobiles, and small household appliances such as printers and copiers. What we are discussing today is The accuracy of the synchronous belt drive in different situations is related to those aspects. In fact, the timing belt itself does not have accuracy, but when it is connected to the motor and there is a load in use, you can judge its accuracy. What we are discussing today is the accuracy in three cases: open loop, semi-closed loop and closed loop.

First, in the open-loop case

In the transmission process of the synchronous belt, the accuracy is not very high only from the perspective of the device itself, and because of the deformation of the wheel belt to a certain extent, it will lead to poor repeatability. Detailed accuracy division, in this case, choosing some timing belts with better quality and better workmanship can reduce certain deformation and improve accuracy.

Second, in the case of semi-closed loop

In the case of semi-closed loop, the mechanical feedback unit generally exists on the motor of the overall equipment, but there is no feedback on the general transmission unit. In this special case, the synchronous belt can only be improved to a certain extent in two ways. Accuracy, first, buy better equipment to ensure that the accuracy of the transmission itself is relatively high, and the second is to improve the accuracy of the control system.

Third, in the case of closed loop

In this case, it is necessary to pay attention to a special part---the grating ruler. Its precision and the precision of the control system jointly determine the precision of the synchronous belt transmission in this case. The synchronous belt is an elastic body, which is used in the printer When it comes into play, his precision determines whether the printed mosquitoes will be misplaced, it's not clear.

This is the accuracy of the synchronous belt in the three cases of open loop, semi-closed loop and closed loop during the transmission process. If you want to improve the accuracy of the synchronous belt yourself, you can refer to the above content and make modifications to achieve the effect you want.
