Technical Field

The invention relates to the field of couplings, in particular to a heat-insulating coupling with a middle lengthened section.

Background

The shaft coupling is an indispensable transmission component in the mechanical field. The driving end of the coupler is used for connecting a driving device, the driven end of the coupler is used for connecting a driven device, and the driven device as a specific actuating mechanism is often required to be arranged in a specific working environment, for example, the working part of a high-temperature type wet pit pump is required to be in a high-temperature environment for a long time. At the moment, the driven device transfers heat to the driving device through the coupler, so that the high temperature of the driving device is out of limit, and the driving device is not beneficial to the working stability and the service life of the driving device.

To address the above issues, heat transfer is currently reduced by adding a longer intermediate section between the driving and driven ends; and the middle section is additionally provided with water cooling or air cooling and the like near the active end.

However, the middle section is lengthened, so that the overall stability from the driving device to the driven device is poor; on one hand, water cooling is increased to cause consumption and waste of water resources, and on the other hand, the safety problem is brought.
