Stepper motor coupling for mounting between stepper motors and loads requires precise transmission performance:
1. Zero clearance: The coupling is not allowed to have clearance during the transmission process, including forward clearance and return clearance;
2, high rigidity: that is, the hysteresis of the transmission is not allowed, otherwise it will seriously affect the accuracy of the stepper motor transmission;
3, low inertia: on the basis of ensuring the transmission strength, the weight of the stepper motor coupling should be reduced as much as possible;
4. Flexibility: The precision servo coupling not only requires high rigidity, but also needs to absorb the deviation between the shaft and the shaft generated during the installation process.
classification:
