The technical solution adopted in the present invention is a kind of shaft coupling, including the first half a coupler, the second half a coupler, the
Flange is provided with one half a coupler, the second half a coupler and connects disk, each flange connects along the circumferential direction equal on the periphery of disk
Cloth is provided with drive rod, and the first half a coupler and the second half a coupler are connected by bearing pin, and the first half a coupler connects with input shaft
Connect, the second half a coupler and input axis connection.
The features of the present invention also resides in：
First half a coupler is connected with input shaft, the second half a coupler with input shaft by axle sleeve.
Axle sleeve is separately fixed on first half a coupler and the second half a coupler by bolt, axle sleeve and input shaft
Connected between output shaft by flat key.
Bearing pin both ends are provided with baffle plate.
Drive rod connects disk to be detachably connected by screw thread with the flange.
Drive rod and the bearing pin are four.
The flange set on first half a coupler connects and boss is provided with the periphery of disk, is set on the second half a coupler
Flange connect set on the periphery of disk it is fluted.
The shape and size all same of boss and the groove.
The beneficial effects of the invention are as follows：
1) in the case of power input is normal, the shaft coupling is used for passing power；After power, which inputs, to interrupt, by
, can be by manually manually driving whole shaft coupling to operate in being provided with drive rod on half a coupler；
2) shaft coupling of the invention transmits moment of torsion between shaft coupling and power transmission shaft by axle sleeve, is logical in connection procedure
Bolt and flat key connection are crossed, therefore improves the reliability of shaft coupling, and the magnitude of interference of the shaft coupling during dress is clapped is not
Need excessive, the machining accuracy of part is improved while the dismounting difficulty of shaft coupling is reduced；
3) shaft coupling of the invention connects in flange and boss is set on the periphery of disk and groove structure is embedded is connected to one
Rise, so as to effectively alleviate from destruction of the recoil strength caused by output shaft to input shaft；
Coupler structure of the invention is simple, manufacturing cost is low, applied widely and reliability is high, can be directly by existing
Shaft coupling transform to obtain.
