Harmonic reducer is a precision component. It acts in intelligent fields such as industrial robots, service robots, and automation equipment. Its accuracy is a very important performance indicator, which directly determines the accuracy and life of the equipment that uses it. How should the accuracy level of the harmonic reducer be measured?

The accuracy level of the harmonic reducer is measured according to its transmission error and free travel.

       1. Free travel refers to the hysteresis of the output shaft in the angle of rotation when the input shaft changes from the positive direction to the reverse rotation under the working state. If the idle distance is less than or equal to 1 arc, it is divided into 1 level, which is represented by the number 1; , represented by the number 3.

2. Transmission error: The transmission error is less than or equal to 30 arc seconds, which belongs to the high-precision reducer, which is represented by the capital letter A, which belongs to the class A; the transmission error is greater than 30 arc seconds and less than or equal to 1 arc minute, which belongs to the precision reducer, and the capital letter B is used. Indicates that it belongs to class B; the transmission error is greater than 1 arc minute and less than or equal to 3 arc minutes, which belongs to the ordinary grade reducer, which is indicated by the capital letter C and belongs to the C class.

The prices of harmonic reducers of different precision grades are also different. Therefore, when purchasing, you can't just look at the price without understanding some important performance parameters. You can only understand the parameters in detail, so as to better choose suitable ones. Harmonic reducer.
