Detailed Description
The utility model discloses a membrane disc coupler, which comprises: the membrane disc, the connecting piece 3 and the intermediate shaft 5; the intermediate shaft 5 is connected with the membrane discs at two sides through a connecting piece; the membrane disc consists of a shaft tractor 6, a membrane 4, a flange 1 and a fairing 2; the diaphragm 4 is connected to the connecting piece 3 through a bolt 8 and can be used for compensating the misalignment of the output end and the load end; the flange 1 is positioned at the top of the diaphragm 4, one end of the flange is connected with power input, and the other end of the flange is power output; the fairing 2 is connected between the diaphragm 4 and the flange 1 through bolts 8; mainly protecting the diaphragm 4 and reducing friction between the diaphragm 4 and the bolts 8 and air during operation; the shaft tractor 6 is embedded in the flange 1 and extends into the connecting piece 3, and when faults such as fracture occur, the intermediate shaft 5 is prevented from moving and damaging other parts.
Example 1
In this embodiment, the connecting piece 3 is formed by aligning two planes of two concentric circles with different diameters, so that the central lines of the two circles are combined in a straight line, and the connection part of the two circles and the planes of the two circles are provided with grooves in opposite directions.
Example 2
