Claims

[Scope of utility model registration request]

This is a shaft joint for light loads, and the shape of this shaft joint is a cylindrical round shaft body 1 with taper screws machined at both ends, and several slits 4 in the taper screw portion 2, and a hexagonal nut for closing. 5 is a tapered threaded part 6 with a tapered thread machined on the inside, the outer shape is a conical slope 7 with one side inclined, and the conical slope 7 is deformed by providing several pressed arc-shaped recesses 8,
, by increasing the tightening torque and tightening the tapered threaded part 6.
A conical eccentric hole 9 is provided on the opposite end face, and the round shaft end face 10 of the cylindrical round shaft body 1 and the eccentric thick walled part 11 of the hexagonal nut 5 for closing As it progresses, the circumferential pressure of the round shaft end surface 10 of the cylindrical round shaft main body 1 is increased to provide a locking effect and a locking part 15, which achieves a locking effect and further tightens the tapered screw of the locking hexagonal nut 5. As the tightening progresses, the portion 6 also firmly tightens the slit portion 4 to the rotating shaft 12 while maintaining the center point of the rotating shaft 12 to be connected.
, is a shaft joint that prevents the rotary shaft 12 from falling out of the shaft hole 3 of the shaft joint when the rotary shaft 12 rotates, and smoothly transmits power.
