Because the size of second spout 10 is greater than the size of first spout 9, and the size of blocking piece 11 is greater than the size of first spout 9, and blocking piece 11 can play limiting displacement, prevents the deviating from of expansion plate 8, and expansion plate 8 stimulate auxiliary spring 12 extension simultaneously for left protective sheath 5 is comparatively slow removal, is convenient for adjust to with installation department 3 looks adaptation, after adjusting, screw up the tight bolt 13 of support in the outside, support tight bolt 13 compresses tightly expansion plate 8, and then spacing after adjusting left protective sheath 5 and right protective sheath 6.
After the left protective sleeve 5 and the right protective sleeve 6 are adjusted, the left protective sleeve 5 and the right protective sleeve 6 are fixed through the fixing lugs 7 by using the fixing bolts, at the moment, the adjusting blocks 25 on the outer sides of the left protective sleeve 5 and the right protective sleeve 6 are rotated, the adjusting blocks 25 are in threaded rotating connection, self-locking is facilitated, the adjusting blocks 25 drive the rotating shafts 23 to rotate, the rotating shafts 23 pull the winding ropes 22, the winding ropes 22 are wound on the outer sides of the encircling parts 24, and the winding ropes 22 are stretched.
The guide wheel 21 assists the stretching of the winding rope 22, and the auxiliary plate 19 blocks the winding rope 22, so that the winding rope 22 can compress the sealing air bag 20, and then the air of the inner sealing air bag 20 is compressed into the outer sealing air bag 20, so that the outer sealing air bag 20 expands, and the connection gaps between the left protective sleeve 5 and the driving end hub 1 and between the right protective sleeve 6 and the driven end hub 2 can be filled by matching of the plurality of sealing air bags 20.
When the coupling is required to be filled with lubricating oil, the lubricating oil is injected through the oil filling pipe 15, the lubricating oil flows into the guide pipe 16 through the oil filling pipe 15, most of the lubricating oil can be filled into the guide pipe 16 firstly because the aperture of the oil filling port 17 is not more than one millimeter, less lubricating oil can be sprayed out through the oil filling port 17, and after the guide pipe 16 is filled with the lubricating oil, the lubricating oil can be uniformly sprayed out from the plurality of oil filling ports 17, so that the lubricating oil can be uniformly sprayed onto the whole coupling.
What is not described in detail in this specification is prior art known to those skilled in the art.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
