Description

Technical Field

[0001] The utility model belongs to the technical field of machinery, in particular to a servo drive mechanism. Background Art

[0002] A servo drive is a system that achieves position, velocity, or acceleration control of a mechanical system through closed-loop control. A servo drive is an automatic control system that tracks input command signals to achieve precise position, velocity, and power output. A mechanical transmission is an intermediate device that transfers the motion and power generated by a power machine to an actuator. It is a torque-speed converter designed to achieve a proper torque match between the power machine and the load, and to adjust the output speed through mechanical transformation.

[0003] In mechatronic systems, the servo motor's variable speed function largely replaces the variable speed mechanism in traditional mechanical transmissions. Speed changes are only implemented through the transmission when the servo motor's speed range fails to meet system requirements. Because mechatronic systems demand high response speeds, the mechanical transmission in these systems serves more than just a solution for torque matching between the servo motor and the load. More importantly, it improves the system's servo performance. To achieve this, mechanical transmission components must have low moment of inertia, low friction, and adequate damping. Servo drives are widely used in industry due to their high precision. However, currently, a single servo drive mechanism struggles to achieve full range of motion freedom in three dimensions.
