Energy-saving and environment-friendly automatic fatigue life testing machine for rubber transmission belt

Abstract

The invention relates to the technical field of conveyor belt fatigue testing machines. The invention further discloses an energy-saving and environment-friendly automatic fatigue life testing machinefor a rubber transmission belt. A tested rubber transmission belt is arranged at a spindle motor; an electromagnetic differential mechanism is arranged at the end, away from the spindle motor, of thetransmission belt; an output shaft of the electromagnetic differential mechanism is connected with a generator rotor serving as a load; a linear feeding device is arranged between a driving wheel anda driven wheel; and a tension sensor is installed on the feeding device. According to the invention, overall control scheme design is carried out on the testing system; the composition and the principle of a test bed measurement and control system are respectively introduced; in combination with test requirements and functions of the test system, hardware model selection of the test machine measurement and control system and a software part of the measurement and control system are designed to complete automatic control and man-machine interaction operation of the test system; and design of the transmission belt fatigue life test system which is energy-saving, environment-friendly and high in test precision is realized.

Description

technical field [0001] The invention relates to the technical field of conveyor belt fatigue testing machines, in particular to an energy-saving and environment-friendly automatic fatigue life testing machine for rubber transmission belts. Background technique [0002] As the core component of the belt drive, the rubber belt is mainly responsible for transmitting the power generated by the motor or engine to other mechanical mechanisms. Fatigue fracture and wear are two common damage forms of the belt. During the working process of the transmission belt, the losses and accidents caused by the failure of the belt cannot be ignored. Among them, the consequences caused by the sudden fracture of the belt during work are the most serious. Threat to the personal safety of relevant staff. In the actual use of the transmission belt, the belt will be replaced with a new belt after a certain degree of wear and tear, which cannot completely solve the problem, and there is a hidden dan...

AI Technical Summary

Problems solved by technology

[0003] Due to the defects of the working mechanism of the traditional mechanically closed drive belt fatigue life test bench, it is difficult to guarantee the accuracy of the slip rate of the tested belt, and the stability of the test load is also relatively poor. The gap between the test conditions and the actual working conditions of the drive belt is relatively large. Therefore, there is a relatively large deviation between the final test results and the actual working conditions, and the test efficiency is low, and the energy saving effect is not obvious

In order to improve the test accuracy, save energy and reduce costs at the same time, a multi-functional, high-efficiency, energy-saving, and high-precision test system for fatigue life testing of electrically-enclosed transmission belts is developed in order to obtain product fatigue performance indicators in the shortest possible time. Therefore, it is of great significance to improve and improve the quality of products. Its significance is to make it possible to improve the domestic transmission belt production line. With the popularity of fatigue life testing machines in the transmission belt production market, it will definitely improve the production level and product quality of the transmission belt industry. , the existing patent CN201773043U, its disadvantage is that it cannot carry out automatic control and data collection, so we propose an energy-saving and environment-friendly rubber transmission belt automatic fatigue life testing machine
