Abstract

The invention relates to a coupling device capable of achieving online separation and joint. The coupling device comprises an input shaft, an input shaft bearing, an output shaft, and an annular triangular wedge block. One side of the input shaft bearing is arranged on a shaft shoulder of the input shaft, the output shaft is connected with the other side of the input shaft bearing, the output shaft is connected with the input shaft through the input shaft bearing, and a wedge-shaped gap is arranged between the input shaft and the output shaft. The annular triangular wedge block is arranged between the output shaft and the input shaft, when the coupling device capable of achieving online separation and joint is separated, the annular triangular wedge block is in the reset state, at least one side of the annular triangular wedge block is separated from the input shaft or output shaft, when the coupling device capable of achieving online separation and joint is in joint, the annular triangular wedge block is in the power transmission state, the two sides of the annular triangular wedge block are tightly attached to the input shaft and the output shaft, and the input shaft drives the output shaft to rotate through the annular triangular wedge block. Friction force between the annular triangular wedge block and the input shaft and the output shaft is used, through hydraulic driving,different kinds of pressing force are adopted, and functions of overload protection, rotating shaft separation and joint and the like of the shaft can be achieved.

Description

technical field [0001] The invention relates to a shaft coupling device, in particular to an online clutchable shaft coupling device. Background technique [0002] In the prior art, there are mainly hydraulic couplings, VOITH safety couplings and gear meshes for overload protection and online clutching of shaft couplings. [0003] The hydraulic coupling is mainly composed of an impeller and a pump wheel. The pump wheel pressurizes the oil and impacts the impeller to realize torque transmission. By controlling the amount of oil, the output speed can be controlled. Since there is no direct mechanical connection between the impeller and the pump wheel, it can be protected when the torque is over. [0004] The VOITH safety coupling is composed of an inner shaft and an outer shaft. By filling the cavity located in the inner wall of the outer shaft with high-pressure oil, the inner wall of the outer shaft expands inward, thereby forming direct contact with the surface of the inne...
