An intelligent safety coupling and its working method

Abstract

An intelligent safety coupling and a working method therefor, which is a novel intelligent safety coupling that uses a real time dynamic torque control actuator (3) to quickly separate a driving side and a driven side of the coupling. A control system (1) on the coupling will analyze real time torque data detected by a torque sensor (8) and compare same with a pre-selected set torque value. If real time torque exceeds the pre-set torque value, the control system (1) will send an instruction to the actuator (3), and the actuator (3) will act immediately to achieve the objective of limiting the torque. The collection, analysis and control of torque dynamic data and the actuator (3) are integrated in the coupling to form an independent intelligent device. An actual dynamic torque value may also be used to correct a preliminary preset loosening torque value of the coupling, so that the transmission system is more accurately and completely protected. The intelligent torque-limiting safety coupling may be widely applied to various industrial fields such as metallurgy, energy, mining, aviation, automotive and engineering machinery.

Description

technical field [0001] The invention relates to the field of transmission systems, in particular to an intelligent torque-limiting safety coupling and a working method thereof. Background technique [0002] The transmission system is an important part of industrial equipment. The dynamic torque on the transmission system is difficult to obtain due to the complex components. Therefore, the design and maintenance of the transmission system has always been a difficult problem for engineers and field equipment personnel. [0003] On the other hand, the setting value of the safety coupling is generally set based on empirical values. It is difficult for designers and users to obtain the actual accurate and real dynamic torque data on the transmission system as a reference, so it will cause the safety coupling There is a large deviation between the design setting value when selecting and the actual real dynamic torque value on the transmission system, and it is difficult to obtain ...

AI Technical Summary

Problems solved by technology

[0005] 1. The error is large, and the error of some torque-limiting couplings sometimes reaches and exceeds + / -30% of the set value;

[0006] 2. The response time is long, which will not be able to effectively limit the impact load actually received by the transmission system, causing potential safety hazards;

[0007] 3. The driving side and the driven side cannot be completely disengaged in time;

[0008] 4. It is difficult to realize the remote control loosening and connection of the coupling;

[0009] 5. The degree of intelligence is not high

[0010] In this context, traditional mechanical safety couplings are increasingly unable to meet the needs of the market, which urgently requires those skilled in the art to solve corresponding technical problems
