工业机器人通常执行重复的动作以完成相同的工序。为保证工业机器人在生产中能够可靠完成工序任务并确保工艺质量，对工业机器人的定位精度和重复定位精度要求很高。因此提高和确保工业机器人的精度就需要采用rv减速器或谐波减速器。

Industrial robots typically perform repetitive actions to complete the same process. To ensure that industrial robots can reliably complete process tasks and ensure process quality in production, high requirements are placed on the positioning accuracy and repeated positioning accuracy of industrial robots. Therefore, to improve and ensure the accuracy of industrial robots, it is necessary to use RV reducers or harmonic reducers.

精密减速电机在工业机器人中的另一作用是传递更大的扭矩。当负载较大时，一味提高伺服电机的功率是很不划算的，可以在适宜的速度范围内通过减速器来提高输出扭矩。而且伺服电机在低频运转下容易发热和出现低频振动，对于长时间和周期性工作的工业机器人，这都不利于确保其精确可靠地运行。

Another function of precision reduction motors in industrial robots is to transmit greater torque. When the load is large, blindly increasing the power of the servo motor is not cost-effective. You can increase the output torque through a reducer within a suitable speed range. Moreover, servo motors are prone to heating and low-frequency vibration during low-frequency operation, which is not conducive to ensuring accurate and reliable operation of industrial robots that work for long periods of time and periodically.

精密减速电机的存在使伺服电机在一个合适的速度下运转，并精确地将转速降到工业机器人各部位需要的速度，提高机械体刚性的同时输出更大的力矩。与通用减速器相比，机器人关节减速电机要求具有传动链短、体积小、功率大、质量轻和易于控制等特点。

The existence of precision reduction motors enables servo motors to operate at an appropriate speed and accurately reduce the speed to the required speed for various parts of industrial robots, improving the rigidity of the mechanical body while outputting greater torque. Compared with universal reducers, robot joint reduction motors require characteristics such as short transmission chains, small size, high power, light weight, and easy control.
