The beneficial effects of the utility model are simple in construction, need not heating, operate more convenient, it is only necessary to one during dismounting
Propping up hexagon and an adjustable wrench can complete, and can transmit high torque, applicable situation is relatively broad.
Accompanying drawing illustrates:
Fig. 1 is this utility model structural representation.
Detailed description of the invention:
With reference to Fig. 1, this utility model specifically uses following embodiment: include slot inner expanding sleeve 2, outer cuff 4 and of inside groove
Fastening bolt 3, fluting inner expanding sleeve 2 opens groove vertically, and fluting inner expanding sleeve 2 cross section is provided with flange bolt hole, flange bolt
Hole is connected with power shaft 1 by fastening bolt 3, and on fluting inner expanding sleeve 2 outer tube wall, hoop is provided with teeth, and teeth are trapezoidal teeth,
Fluting inner expanding sleeve 2 inwall connects liftout bolt 10, and fluting 2 inwalls of inner expanding sleeve are connected with end-equipment power shaft 7 by key 6；
The outer cuff 4 of inside groove is made up of two semi-circular structural members of split, and two semi-circular structural members of split are interlocked by the fastening wing, and two
The individual fastening wing connects by interior hexagonal fastening bolt 9 is fixing, and the outer 4 inwall hoops of cuff of inside groove are provided with teeth groove, teeth groove and teeth
Modulus is consistent, and teeth groove is meshed with teeth, and on outer cuff 4 drum outer wall of inside groove, hoop is provided with enhancing steel ring 8, enhancing steel ring 8 outer wall
It is provided with suspension ring 5.Described flange bolt hole number is ten, and the fastening bolt 3 being connected with flange bolt hole is ten.Described
Two fastening the wings on be equipped with hexagon socket head cap screw hole, hexagon socket head cap screw hole be centrosymmetrically arranged fastening the wing on, interior hexagonal spiral shell
Keyhole matches with interior hexagonal fastening bolt 9.
During installation, hexagonal fastening bolt 9 in the high intensity on the wing is tightly consolidated in school, makes the teeth groove in the outer cuff 4 of inside groove compress and opens
The teeth of 2 on groove inner expanding sleeve, the endoporus of fluting inner expanding sleeve 2 tightens, and produces interference fit with axle.By with the coordinating to end of key 6
End transmission moment of torsion and motion.Fluting inner expanding sleeve 2 is provided with flange bolt hole, can be by fastening bolt 3 and power shaft 1, clutch
Connect Deng power transmission.Wherein fluting 2 inwalls of inner expanding sleeve are by key 6 and winch, slush pump, rotating disk, oil pumper, various
The power shaft 1 of interlocking equipment connects.
During dismounting, first universal drive shaft or other power transmissions of outer for inside groove cuff 4 Flange joint are pulled down, then dismantle
The fastening bolt 3 of the outer cuff 4 of inside groove, pulls down outer for inside groove cuff 4, re-uses and eject spiral shell, 10 ejecting on fluting inner expanding sleeve 2
Fluting inner expanding sleeve 2 is separated by screw 10 with axle, so far dismantles complete.
