Kind associated mode headstock gear, Publication No.：CN103015376A；Publication date is：On April 3rd, 2 013；The headstock gear is direct connection
Formula list hanging point headstock gear, including rack, motor, shaft coupling, connecting seat, speed reducer, cable drum, steel wire rope, balance are slided
Wheel apparatus and running block；Motor is fixed on the rack by connecting seat；The shaft of motor, shaft coupling, speed reducer it is defeated
Enter axis and output end and cable drum is coaxially set；The speed reducer is planet-gear speed reducer, including mounting flange, work
Dynamic flange and input shaft；The mounting flange of speed reducer is fixed on the rack, and the barrel end of loose flange and cable drum is solid
Fixed connection, the structure division of the loose flange side of speed reducer are located inside cable drum；The cable drum includes rotation
Shaft, fixed frame, dextrorotation grooving and left-handed grooving；Non- speed reducer of the rotary shaft with fixed mount setting in cable drum connects
The inside of side, fixed frame are weldingly fixed on inside the non-speed reducer connection side of reel, and one end and the fixed frame of rotary shaft weld
Fixation is connect, the other end is pierced by rack and the bearing support by being arranged in rack, the cylinder of rotary shaft and cable drum from inside to outside
Body is coaxially set；Motor is connected by shaft coupling with the input shaft of speed reducer, torque after the deceleration mechanism deceleration of speed reducer
It is exported by loose flange.Disadvantage is that：The speed reducer and cable drum of the associated mode headstock gear lead to after independently manufacturing
Flanged joint is crossed, occupancy volume is big, dead weight is also big, not compact enough in structure, and the transmission of speed reducer is positioned at the one of cable drum
End, torque transmission is unreasonable, be easy to cause unbalance loading.
Invention content
The object of the present invention is to provide a kind of headstock gear, which has high transmission accuracy, compact-sized, loading capacity
Greatly, the advantages that noise is small, good braking effect.
The object of the present invention is achieved like this：A kind of two-fold cylinder headstock gear, including motor, reel one and reel two, electricity
The shell of machine is connected on bearing one, is sequentially connected between the output shaft and reel one, reel two of motor, the reel one and volume
It is connected through flange between cylinder two, the output shaft end of motor is connected through shaft coupling with central shaft one end, and the central shaft other end can turn
It is supported on dynamicly on one corresponding flange of reel, driving gear, the inner cavity of reel one is installed close to flange one end on central shaft
In be equipped with ring gear one and ring gear two, between the driving gear and ring gear one be equipped with the first driven gear, first is driven
Gear engages respectively with driving gear, ring gear one；The gear shaft of first driven gear is fixed on first gear frame, in described
The first central gear and the second central gear are set with successively close to driving gear side, the first gear frame and the in mandrel
One central gear is mutually fixed, and the second driven gear, the second driven gear and the are equipped between the first central gear and ring gear two
One central gear, ring gear two are meshed respectively；The gear shaft of second driven gear is fixed on second gear frame, and described second
Tooth rest is mutually fixed with the second central gear, between the second central gear and ring gear two be equipped with third driven gear, third from
Moving gear is meshed respectively with the second central gear, ring gear two；The gear shaft of third driven gear is fixed on third tooth rest
On, the shaft coupling be externally provided with one mutually fixed base bearing mounting base of bearing, the inner wall of base bearing mounting base and reel one it
Between base bearing is installed；The third tooth rest is mutually fixed with base bearing mounting base.
At work, the output shaft of motor first delivers torque to central shaft to the present invention, and central shaft drives driving gear to turn
Dynamic, driving gear drives the rotation of the first driven gear, the first driving gear that the rotation of first gear frame, first gear frame is driven to pass through
First central gear drives the rotation of the second driven gear, second gear frame to drive third driven tooth to rotate by the second central gear
It is dynamic, due to third tooth rest be it is fixed, third driven gear can only drive reel one and reel two to rotate, real
The now steel wire rope tightening on reel one and reel two is unclamped.Compared with prior art, beneficial effects of the present invention
It is：First, passing through the retarded motion of the first driven gear, the second driven gear, third driven gear so that the high speed of motor
Movement can be converted into the low-speed motion of reel one and reel two, and torque of the primary action on reel one is from reel one and reel
It is inputted between two, position is generally located between reel one and reel two, advantageously ensures that balance when folding and unfolding steel wire rope.Its
Two, the axial dimension of headstock gear can be greatly reduced, is conducive to it and is arranged in small space.Third, when reel one rotates, by
Gear ring one, ring gear two are meshed with corresponding first driven gear, the second driven gear, third driven gear in the inner, because
This, the first driven gear, the second driven gear and third driven gear respectively can be to one passing power of reel, the first driven tooths
Wheel, the second driven gear and third driven gear uniform force, torque transmit steady.Fourth, the apparatus structure is compacter, do not have
There are independent speed reducer, cost to substantially reduce, meanwhile, transmission mechanism is worked good with reel one, and small, torque is big, noise
It is small.Fifth, the device radiation is good, the heat that inside generates can ensure that device use can by the rapid heat dissipation outward of reel one
It leans on, lubricating oil not mutability.The device is exclusively used in the keying of gate.
To ensure that one work of reel two of reel is more reliable and more stable, the one end of the reel two far from flange is equipped with bearing
Two, it is connected through support shaft two and spring bearing between bearing two and reel two.
As a further improvement on the present invention, the surface of the reel one and reel two is equipped with spiral steel wire rope groove,
Reel one is opposite with the hand of spiral of steel wire rope groove on reel two.When reel one and two respective haulage cable of reel are wound,
The axial force that generation can be eliminated avoids bearing impaired.Steel wire rope groove increases the area contacted with the external world, can further help
Heat dissipation.
To improve axial carrying capacity, the base bearing is tapered roller thrust bearing and is arranged with two.
For ease of installation and transfer motion power, realize that the deceleration of large speed ratio, the internal diameter of the ring gear one are more than ring gear two
Internal diameter.
For ease of installation, between first gear frame and the first central gear, between second gear frame and the second central gear,
It is connected through spline between third tooth rest and base bearing mounting base.
As a further improvement on the present invention, it is set between the end face and the end face of the second central gear of the third tooth rest
It is equipped with wearing ring.Wearing ring can reduce abrasion, ensure that the end face of the second central gear is not easy to wear.
