Description

technical field [0001] The invention relates to a constant force output device. Background technique [0002] According to different application environments and application requirements, there are various structures and implementation methods for constant force output. Dynamic constant force output refers to loading a constant force value on a dynamically moving target workpiece. [0003] Hanging the target workpiece through weights is the simplest and most commonly used method of applying constant force. Since the mass of the weight is constant, the force acting on the target workpiece remains unchanged, but when the target workpiece is accelerating or decelerating, the weight The weight will generate an additional force acting on the target workpiece due to the influence of its own inertial force, and the greater the mass of the weight, the greater the effect, so this method is only suitable for low-speed or uniform-speed movement of the target workpiece. Torque motors,...
