Row selection is installed, preferably most suitable connected mode.On the other hand, the disc spring and the attachment structure of screwed hole that the present invention is set can
To play a part of bumper and absorbing shock, for needing the non-rigid startup of buffer shock-absorbing very applicable, after connecting, motor presses certain
One single direction is rotated, and the torque of main shaft output largely will not pass to drive disk assembly moment, can first pass around the deformation of disc spring
A release part, then largely passes to the drive disk assembly of connection, moreover, in necessity again when disc spring, which is deformed, to be reached to a certain degree
When, it can make to isolate one section of buffer distance between connecting seat and disc spring, at the beginning of transmission is connected, corresponding connecting seat is being screwed into it
When not being in contact with disc spring in nested big connecting seat, a part of torque is discharged in advance, expands the effect of bumper and absorbing shock,
What its thread pitch (connecting seat can be allowed to have a little radial-play) connected can also zoom in or out as needed
Adjustment, to change cushioning ability to a certain extent.Finally, the cylindrical spring for the second connecting shaft that the present invention is set possesses very big
Cushioning effect, and under the superposition of shock absorbing effect layer by layer in outside several layers of connecting seats, more go for big torsion
The equipment that square operates and needs vibration damping to protect.
