Coupling with quick removable sleeve cover

Abstract

The invention discloses a coupling with a quick removable sleeve cover. The coupling comprises two shaft sleeves and a shaft cover, wherein the two shaft sleeves respectively sleeve an active drivingshaft and a slave driving shaft, the shaft cover sleeves the outer sides of the two shaft sleeves and is used for connecting the two shaft sleeves, and an outer sleeve cover can sleeve the outer sideof the shaft cover according to the magnitude of torque of the service condition so as to increase the load borne by the torque. The coupling has the advantages of the simple structure and conveniencein removal and installation, a knocking mode of a traditional removing and installing process is improved, abnormal damage to a bearing is avoided, no space limitation exists in mechanical seal maintenance such as replacement of a pump shaft and the like, the effects of convenience and modular design are achieved, a large axial installation error is permitted during installation, and the oscillation phenomenon caused by an installation driving error can be obviously reduced, so that the common phenomenon of axial magnetic displacement of a motor device is effectively avoided, the energy consumption is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a cover quick-detachable shaft coupling, which belongs to the technical field of mechanical transmission components. Background technique [0002] With the development of social industry, the application of transmission equipment is ubiquitous. As an important component of transmission equipment, the performance of couplings directly affects the normal operation of the entire production system. Couplings are mechanical parts used to connect the driving shaft and driven shaft in different mechanisms so that the two can rotate together. In high-speed and heavy-duty power transmission, some couplings also have buffering, vibration reduction and The role of shafting dynamic performance. At present, the common couplings include the driving coupling part connected with the driving shaft, the driven coupling part connected with the driven shaft, and the intermediate connecting part connecting the ma...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned existing shaft coupling structure needs to carry out processes such as heating and drawing the shaft sleeves connected with the main and driven shafts during disassembly and assembly. It is very complicated, especially for the replacement and disassembly process of mechanical shaft seals such as pump shafts (there is a space limitation in the replacement of mechanical shaft seals / the driven shaft side of the coupling needs to be disassembled / the driving shaft side needs to be completely disassembled and retreated to make room), Traditional percussion disassembly and maintenance are inconvenient and the downtime for maintenance is long; when this type of coupling corresponds to the main and driven shafts of different sizes and models, all components need specific dimensions, and the installation of the main and driven shaft couplings is also necessary. A fixed gap value is required, so it is difficult to achieve standardization and modularization; when installing the coupling, it is necessary to align the center of the driving shaft of the driving end equipment and the center of the driven shaft of the driven end equipment, if there is a deviation in alignment or If there is a large error, it will seriously damage the connecting parts of the main and driven shafts of the coupling and the corresponding equipment, and the existing coupling is difficult to achieve bare shaft alignment and the alignment accuracy is not high, and the error is large; in addition , the existing coupling does not allow large angular installation errors, so its axial vibration is more obvious during use
