Device used for carrying out rope performance study on tandem type rope sheave structure

Abstract

A device used for carrying out a rope performance study on a tandem type rope sheave structure is mainly formed by a mounting base, guide wheel assemblies, rope sheave assemblies, a reducer, guiding sheaves, balancing weights and the like in an assembled mode. Through the adjustment of corresponding assemblies, the study on the rope performance of the tandem rope sheave structure in a circumferential-assembling mode and a linear-assembling mode can be achieved. A trapezoid cut is formed in each rope sheave in the radial direction, through the match of a locking nut and the two side faces of each trapezoid notch, the lengths of tandem ropes are adjusted and calibrated, and the periphery of each rope sheave is marked with scales to calibrate the turn angle deviation between two rope sheaves. The driving force and loads of the device are provided by the reducer having a self-locking function and the balancing weights. The study device not only can carry out the study on rope tension and turn angle deviation performance among the rope sheaves to obtain the synchronism motion and variation law among the tandem type rope sheaves, but also can achieve the study on fatigue reliability of the ropes, and further analyzes factors affecting the fatigue reliability of the ropes.

Description

technical field [0001] The invention relates to a device for conducting rope performance research on a serial rope wheel structure, which belongs to the field of mechanical engineering flexible system assembly. Background technique [0002] Ropes are widely used in ships, civil elevators, mining machinery, military aerospace and other places because of their advantages such as flexibility, high tensile strength, good shock resistance, and compact structure. The performance requirements for general-purpose ropes are not However, for the rope used for precise transmission control, it puts forward extremely high requirements for its performance. Not only the rope is required to have good performance characteristics, but also the motion accuracy generated during the transmission motion must also be controlled within a certain range. In the range. In order to realize the precise motion control of the rope, in the actual assembly process, people mainly rely on experience to ensur...

AI Technical Summary

Problems solved by technology

In the process of rope motion transmission, the force transmission not only has the characteristics of connection and coupling, but also due to the characteristics of the rope itself and the phenomenon of friction and creep between the rope and the sheave, it will cause the attenuation of the tension on the rope and the motion transmission. The hysteresis of the rope pulleys causes a deviation of synchronous movement between the sheaves connected in series. The more series of sheaves in series, the more serious the deviation of synchronicity will be.

At present, there is no systematic theory in the research on the precise motion control of ropes. Experimental research is still an effective means to analyze the performance characteristics of ropes, and it is also a method commonly used in the world. Therefore, the rope performance research device based on the application status The design of the rope becomes the key to the analysis of the precision motion transmission performance of the rope
