Ultra-large torque standard machine weight loading system

Abstract

The invention relates to an ultra-large torque standard machine weight loading system. The system is provided with a weight part, a weight tray used for containing weights, a hanging part which is connected with a standard force arm and used for hanging the weight part, a support part used for fixing and supporting a loading system, electronic control systems and lifting mechanisms, wherein the electronic control systems and the lifting mechanisms are used for lifting the weight part, the weight part is composed of an upper layer weight set and a lower layer weight set, the centers of all the weights of the upper layer and the lower layer are on the same vertical straight line, the weight tray is divided into an upper layer weight tray body and a lower layer weight tray body which are used for bearing the upper layer weight set and the lower layer weight set respectively, and the bottom of the upper layer weight tray body and the bottom of the lower layer weight tray body are each connected with one electronic control system and one lifting mechanism and used for controlling and driving the weight part to move up and down. Through the system, the automatic large weight loading function can be achieved, and the weight loading requirement of a large standard torque device is met. Meanwhile, the system has the limitation function, the weights can be loaded more stably, and the weights can return to the initial positions after the system is unloaded.

Description

technical field [0001] The invention relates to measurement detection, torque detection and calibration, and torque testing systems, in particular to a super-large torque standard machine weight loading system. Background technique [0002] The ultra-large static weight torque standard machine is a high-precision torque measurement equipment. This equipment is composed of a standard force arm and a standard weight. The precise torque value obtained by the ultra-large deadweight torque standard machine comes from the product of the length of the standard arm and the weight of the standard weight. In order to obtain super large torque, the super large static weight torque standard machine must be composed of a considerable length arm and a considerable mass of weights. However, because the length of the arm is limited by the processing capacity and the use of space, it is generally not greater than 2 meters. Therefore, the only way to meet the torque requirement is to incre...
