A low-torque loading device provided by the present invention comprises a tooth-shaped belt wheel, a tooth-shaped belt, a first spring, a second spring, a zero setting pull rod, a zero setting bolt and nut combination, a shell and a cover plate, the tooth-shaped belt wheel, the tooth-shaped belt, the first spring and the second spring are installed in the shell, the tooth-shaped belt wheel is connected with the shell, the tooth-shaped belt wheel is kneaded with the tooth-shaped belt, and the zero setting bolt and nut combination is connected with the shell. One end of the cog belt is fixedly connected with the bottom frame of the shell through a first spring, and the other end of the cog belt is connected with a zero setting pull rod penetrating through the inner side of the bottom frame of the shell through a second spring. According to the invention, through the positive correlation of the difference between the load torque and the tension of the double springs and the adoption of differential loading, the error caused by the springs is eliminated, the error is reduced, and the loading precision is improved.

    本发明提出一种低扭矩加载装置,包括齿形带轮、齿形带、第一弹簧、第二弹簧、调零拉杆、调零螺栓螺母组合、壳体和盖板,所述的齿形带轮、齿形带、第一弹簧和第二弹簧安装在壳体内,齿形带轮与壳体连接,齿形带轮和齿形带捏合,组成同步传动结构,齿形带一端通过第一弹簧与壳体底边框固定连接,另一端通过第二弹簧与穿过壳体底边框内侧的调零拉杆连接。本发明通过负载扭矩与双弹簧拉力之差正相关,采用差分加载,将由弹簧引起的误差消除掉,降低误差,提高加载精度。
