Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a shaft coupling that transmission is stable, including first cover shell 1 and second cover shell 8, first cover shell 1 is close to the one end fixed mounting of second cover shell 8 has threaded connection portion 4, and the inside internal thread of carving with threaded connection portion 4 adaptation in one side of second cover shell 8, first cover shell 1 and second cover shell 8 are the annular sleeve, and first cover shell 1 and the 8 outside array of second cover shell are provided with the directional centre of a circle's of a plurality of groups screw through-hole, and the inboard of first cover shell 1 and second cover shell 8 all rotates in screw through-hole department and is provided with along its length direction's conflict piece 9, first cover shell 1 and second cover shell 8 and the equal threaded rod 7 of screw through-hole department threaded connection one end and conflict piece 9 contact.
Further, the outer side of the first casing 1 close to the second casing 8 is concentrically provided with a fixed ring plate 5, a plurality of groups of bar-shaped openings pointing to the circle center are uniformly formed in the fixed ring plate 5, the bar-shaped openings in the fixed ring plate 5 are located under the threaded rod 7, and the bar-shaped openings are parallel to the threaded rod 7.
Specifically, the threaded rod 7 is kept away from the equal thread bush of one end of the contact piece 9 and is provided with a threaded sleeve 6, and one end of the threaded sleeve 6 is fixedly provided with the connecting block 2.
Specifically, the connecting block 2 is provided with a circular through hole communicated with the strip-shaped opening on the fixed ring plate 5, and the fixed ring plate 5 and the connecting block 2 are provided with a nut pair 3 for locking in the circular through hole and the strip-shaped opening in a penetrating manner.
