Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
Referring to Fig.1, it is a kind of chain wheel transmission shaft disclosed by the invention, including main shaft 1 cylindrical and is set in master
Transmission gear 2 and sprocket wheel 3 on axis 1.
Referring to Fig. 2, Fig. 3, one end of 1 length direction of main shaft is provided with and the integrally formed columned extended segment of main shaft 1
11, extended segment 11 and main shaft 1 coaxial arrangement and extended segment 11 diameter compare main shaft 1 diameter it is small.The other end of main shaft 1 is arranged
Have in the form of annular discs and is compared with the integrally formed flange 12 of main shaft 1, flange 12 and the diameter of the coaxial arrangement of main shaft 1 and flange 12
The diameter of main shaft 1 is big.
In conjunction with Fig. 1, transmission gear 2 is installed on main shaft 1 close to one end of extended segment 11, and sprocket wheel 3 is installed on the axle body of main shaft 1
On.
Referring to Fig.1, Fig. 2, transmission gear 2 include coaxial arrangement and integrally formed axle sleeve 21 and outer ring band wheel rim with teeth
22, axle sleeve 21 passes through wheel rim 22 and wherein one end of axle sleeve 21 is stretched out from the wherein side of 22 thickness direction of wheel rim.Axle sleeve 21
Inner hole is stepped hole, is located at one section of the stretching wheel rim 22 of axle sleeve 21 for lesser one section of diameter in the inner hole of axle sleeve 21.Axle sleeve 21
Inner hole in the diameter dimension of one section of diameter dimension and main shaft 1 that is relatively large in diameter match, lesser one section of the diameter of diameter
Size and the diameter dimension of extended segment 11 match.When transmission gear 2 and main shaft 1 to be installed together, by 21 inner hole of axle sleeve
Biggish one section is sleeved on main shaft 1, and lesser one section of diameter of bore is sleeved on extended segment 11.
When the chain wheel transmission shaft is installed on the box body of chain window-opening machine, the axle sleeve 21 of transmission gear 2 stretches out wheel
One end revolution of edge 22 is connected on the box body of chain window-opening machine.
Referring to Fig. 3, offered on the side wall of one end of extended segment 11 in main shaft 1 several open at one end closed at one end
The first card slot 13 being axially arranged, the first card slot 13 are arc groove.First card slot 13 is uniformly set along the circumferencial direction of main shaft 1
It sets.
Referring to Fig. 2, Fig. 4, in the inner hole of axle sleeve 21, offered on one section of side wall being relatively large in diameter and the on main shaft 1

It is same when steel ball 4 is stuck between the first mounting groove 211 and the first card slot 13, transmission gear 2 rotates
Step drives main shaft 1 to be rotated.When needing individually rotation main shaft 1, main shaft 1 is pulled, main shaft 1 is pulled out from the inner hole of axle sleeve 21
Out, so that the first mounting groove 211 of the first card slot 13 and axle sleeve 21 on main shaft 1 be made to be in phase along the axial direction of main shaft 1
Wrong state, steel ball 4 is located between the first mounting groove 211 of axle sleeve 21 and the extended segment 11 of main shaft 1 at this time.When needing to make main shaft 1
When linking with transmission gear 2, promotion by from main shaft 1 to transmission gear 2, make the first card slot 13 of main shaft 1 again with the first installation
Slot 211 is oppositely arranged, and steel ball 4 is between the first card slot 13 and the first mounting groove 211 at this time.
The length that the length of extended segment 11 compares the first mounting groove 211 is long, thus in the first card slot 13 and axle sleeve of main shaft 1
For 21 the first mounting groove 211 in when being staggered, extended segment 11 is still located at the lesser intersegmental part of diameter in 21 inner hole of axle sleeve.For
Convenient for when main shaft 1 is mobile to 2 direction of transmission gear, steel ball 4 smoothly snap onto the first card slot 13 and the first mounting groove 211 it
Between, chamfering 131 is provided at the open end of the first card slot 13.
Referring to Fig. 2, Fig. 5, sprocket wheel 3 includes the wheel case 31 of coaxial arrangement and outer ring has the wheel bodys 32 of the gear teeth, wheel case 31 with
It is integrally formed between wheel body 32.Wheel case 31 is across the both ends of wheel body 32 and 31 length direction of wheel case respectively from the thickness side of wheel body 32
To both ends stretch out.The diameter of bore of wheel case 31 and the diameter of main shaft 1 match, when wheel case 31 is sleeved on main shaft 1, wheel
Set 31 can be slided on main shaft 1.The sum of the length of wheel case 31 and the thickness of wheel rim 22 of transmission gear 2 open a window with chain type
The tray interior width dimensions of machine match, i.e., when chain wheel transmission shaft is encased in the tray interior of chain window-opening machine, pass
The wheel rim 22 of moving gear away from sprocket wheel 3 the side of side and wheel case 31 far from transmission gear 2 respectively with chain window-opening machine
The opposite two sides side wall of box body abuts against.Spaced and interval size and chain type between wheel case 31 and the flange 12 of main shaft 1
The wall thickness of the box body of window opener matches, thus when being encased in the tray interior of chain window-opening machine when chain wheel transmission shaft,
Flange 12 is located at the outside of the box body of chain window-opening machine.
Several second card slots 14 are offered along the circumferencial direction of main shaft 1 on the axle body of main shaft 1, the second card slot 14 is arc
Shape slot.On the side wall of 31 inner hole of wheel case of sprocket wheel 3, the position opposite with the second card slot 14 of wheel case 31 offers open at one end one
Closed second mounting groove 311 is held, the second mounting groove 311 is arranged along the axial direction of wheel case 31.Second mounting groove 311 is similarly arc
Shape slot.A complete hole is surrounded between second card slot 14 and the second mounting groove 311.Positioned at the second card slot 14 and the second mounting groove
The hole that steel ball 4, the diameter of steel ball 4 and the second card slot 14 and the second mounting groove 311 are surrounded is placed in 311 holes surrounded
Diameter matches.When the length of second card slot 14 can make to extract state out from the axle sleeve 21 of transmission gear 2 in main shaft 1, second
The both ends of 14 length direction of card slot are still located at the length direction both ends of the second mounting groove 311.
Referring to Fig. 6, for convenient for pulling main shaft 1, the radial direction offered on the side wall of flange 12 along flange 12 runs through
The through-hole 15 of flange 12 is equipped with the pull ring 5 of semicircular in shape in through-hole 15.The both ends in 5 radian direction of pull ring are respectively set
Have for extending into inserting column 51 in through-hole 15, inserting column 51 and pull ring 5 are integrally formed.Inserting column 51 is inserted into through-hole 15 and and through-hole
It turns round and is connected between 15, so that pull ring 5 be made to be able to carry out rotation.On a side surface of the flange 12 away from main shaft 1, it is located at pull ring
The concave station 16 to match with the shape of pull ring 5 is offered in 5 rotation direction.When pull ring 5 is rotated to 16 direction of concave station, pull ring
5 are transferred on concave station 16 and abut against with the table top of concave station 16.
Another aspect of the present invention additionally provides a kind of chain window-opening machine, which includes that present invention institute is public
The chain wheel transmission shaft opened.When encountering power failure, main shaft 1 is extracted outward, makes the first card slot 13 and the transmission gear 2 on main shaft 1
On the first mounting groove 211 interlock, manually rotate main shaft 1, make main shaft 1 with movable sprocket 3 rotate, sprocket wheel 3 drive chain movement, from
And open window is closed.
