Abstract

A low inertia spring torsion bar type constant force mechanism belongs to a constant force loading mechanism. The invention aims to solve the limitation problem of the existing passive constant force output device. In the low-inertia spring torsion bar type constant force mechanism of the present invention, the two ends of a plurality of springs are respectively hinged with the input shaft of the constant force mechanism and the output reel of the constant force mechanism; the torsion bar is located inside the input shaft of the constant force mechanism, and the torsion bar The two ends of the constant force mechanism are respectively fixedly connected with the input shaft of the constant force mechanism and the output reel of the constant force mechanism. This structure fully considers the use requirements of the constant force mechanism. Achieve continuous output of constant torque throughout the transmission process. The invention has the outstanding advantages of simple structure, low inertia, high torque and high sensitivity, and strong versatility. It provides constant force output for high-frequency changing loads, and has a wide range of applicable torque values, high stability of output torque values, and low moment of inertia. Low inertia spring torsion bar constant force mechanism.

Description

technical field [0001] The invention belongs to a constant force loading mechanism, in particular to a low inertia spring torsion bar type constant force mechanism. Background technique [0002] Constant force loading mechanism is widely used in paper roll, thermal power generation, material testing, aerospace equipment and other fields, and it can directly affect the safety and reliability of equipment. Especially in the field of aerospace, it is often used as a ground verification method to verify the performance of spacecraft through the constant force mechanism to provide micro-low gravity compensation. The traditional gravity compensation methods include counterweight balance, air flotation, water flotation, suspension method, etc. Among them, the gravity simulation of the suspension method has two methods: active compensation and passive compensation. [0003] After searching the literature of the prior art, it is found that the passive constant force output devices c...
