Embodiment:
Fig. 1-4 is please referred to, the utility model provides technical solution: the cargo unloader quick-replaceable dress in high speed rotation joint
It sets, including motor casing 1, the upper end of motor casing 1 is longitudinally bolted with fastening screw 2, by 1 set of the motor casing outer wall in motor
On, it is turned on the outer wall of motor, is haved the function that motor locking by the rotation of fastening screw 2；
The bottom of motor casing 1 is provided with lantern ring 4, and transverse splicing has cross support arm 5 in lantern ring 4, covers on the outer wall of cross support arm 5
It is connected to sliding sleeve 6, limit rack gear 7 is provided on the lower surface of cross support arm 5, the downside of sliding sleeve 6 is plugged with push rod 8, and push rod 8 is towards limit
One end of position rack gear 7 is connected with grafting tooth head 9, is supported by fastening spring between grafting tooth head 9 and the inner cavity lower surface of sliding sleeve 6
10, and fastening spring 10 is socketed on the outer wall of push rod 8, as shown in figure 3, limit 7 flank of tooth of rack gear is on the oblique right side in left side
In a vertical shape, the left side right side in a vertical shape of 9 flank of tooth of grafting tooth head is oblique, so that sliding sleeve 6 is moved to right with respect to cross support arm 5
When grafting tooth head 9 right side opposite with the limit tooth left side of rack gear 7 slide and make the drive push rod 8 of grafting tooth head 9 to cunning
The outside of set 6 is mobile, and fastening spring 10 is compressed, so that sliding sleeve 6 can move right with respect to cross support arm 5, otherwise when cunning
When the opposite cross support arm 5 of set 6 is moved to the left, since the left side of grafting tooth head 9 and the tooth right side wall of limit rack gear 7 mutually limit,
So that sliding sleeve 6 can not move to left (similar with the working principle of ratchet and pawl arrangement) with respect to cross support arm 5；
The upper end of sliding sleeve 6 is bolted with column 11, and the top of column 11 is bolted with retainer ring 12, the two sides of 12 upper end opening of retainer ring
Snap-arms 13 are connected with by pin shaft, 13 upper end of snap-arms of two sides is provided with connecting plate 14, the connecting plates 14 of two sides it
Between pass through bolt assembly connect.
Wherein, the lower end of fastening screw 2 extends to inside motor casing 1, and fastening screw 2 is located inside motor casing 1
It is socketed with arc backing plate 3 on one end, by the setting of arc backing plate 3, fastening screw 2 is avoided directly to contact with the outer wall of motor,
To avoid damaging the outer wall of motor；
The outer wall both ends of cross support arm 5 are provided with stop collar, by the setting of stop collar, avoid sliding sleeve 6 from cross support arm 5
It falls；
Sliding slot is offered on axial direction on the antetheca of cross support arm 5 along cross support arm 5, is set on the inner cavity antetheca of sliding sleeve 6
It is equipped with sliding block compatible with sliding slot, by the mating reaction of sliding block and sliding slot, prevent sliding sleeve 6 is relative to cross support arm 5 from rotating,
So that limit rack gear 7 and grafting tooth head 9 remain face；
Retainer ring 12, snap-arms 13 inner sidewall on rubber pad is bonded with by bonding agent, by the setting of rubber pad, make
The frictional force obtained between retainer ring 12, snap-arms 13 and shaft increases.
Working principle: when disassembly, 1 set of motor casing (is selected in advance on the outer wall of motor according to the outer diameter of specific motor
Take the internal diameter of motor casing 1 that 1 internal diameter of motor casing is made to be greater than motor outer diameter), fastening screw 2 is tightened, and make fastening screw 2
Arc backing plate 3 is pushed to be tightly attached on the outer wall of motor.By snap-arms 13, turned-out unlock is opened on retainer ring 12, so that retainer ring 12,
Snap-arms 13 are connected on the outer wall of shaft and will be connected between connecting plate 14 by bolt assembly, so that motor and shaft
Between be fixed.
The bindiny mechanism between motor and shaft is dismantled, after disassembly, pushes sliding sleeve 6 to slide to the right on cross support arm 5,
To which shaft be removed from motor.
When installation, continue aforesaid operations, old shaft is removed, by new shaft be connected to retainer ring 12, snap-arms 13 it
Between, push rod 8 is pulled down and grafting tooth head 9 is declined, fastening spring 10 is generated elastic force by compression at this time, and sliding is slided
Set 6 is mobile to the left end of cross support arm 5, until new shaft and rotor axis of electric is close, Panasonic's push rod 8, in fastening spring 10
Elastic force acts on lower grafting tooth head 9 and is clamped with limit rack gear 7, so that shaft will not move to left, and not under external force, sliding sleeve
6, which not will drive shaft, moves to right, and connection between shaft and rotor axis of electric can reach to the effect of replacement.
