Part ring, the connection male member are located on the half shaft coupling male seat other end, and the star wheel groove is also set to the half shaft coupling female seat
The other end.
In a kind of preferred embodiment of star-wheel shaft coupling provided by the utility model, the star-wheel is to reinforce nylon material.
The working principle and beneficial effect of the star-wheel shaft coupling of the utility model：
Star-wheel shaft coupling is made of six star-wheels and two half a couplers, can effectively absorb shock loading and compensation installation misses
Difference, and the resistance of the axial float of Cone-shaped electric machine can be reduced, because star-wheel is made using nylon material is reinforced, in relative motion
When, cylindrical star-wheel makees rolling movement on the pawl face of half a coupler, so the resistance of motion is small.
Using star-wheel shaft coupling, opening, the braking maneuver of Cone-shaped electric machine brake are sensitiveer, and electric block is safer.
Star-wheel shaft coupling is made of two half a couplers, six star-wheels and a retainer, the trisection of half a coupler
Claw type transmits motor torque by 6 star-wheels, can effectively absorb shock loading and compensation installation error；Star-wheel shaft coupling is connection
The bridge of Cone-shaped electric machine and retarder, conical motor rotor be powered when, motor is under axial magnetic pulling force effect, it is necessary to forward or
Play (1.5mm or so) backward could open the brake of motor taper, ensure motor normal work.Therefore half a coupler needs to meet
It moves axially 1.5mm or so to require, the claw type of two and half two shaft couplings can do relative rolling with 6 star-wheels, so movement resistance
Power is small, best can meet the requirements.
