It is only the utility model part of the embodiment to apply example, rather than whole embodiments.Based on the embodiment in the utility model,
The every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, belongs to this reality
With novel protected scope.
Fig. 1 to Fig. 3 is referred to, Fig. 1 is a kind of facing for crank flying shears gear-box disclosed in the utility model embodiment 1
Figure, Fig. 2 are the first input shafting and the first output shaft of a kind of crank flying shears gear-box disclosed in the utility model embodiment 1
The sectional view of system, Fig. 3 are a kind of the second input shafting and the of crank flying shears gear-box disclosed in the utility model embodiment 1
The sectional view of two output shaftings.
The utility model discloses a kind of crank flying shears gear-box, including：Casing 1；The first input being arranged on casing 1
Shafting 2, including the first input shaft 16, the clutch shaft bearing 17 being arranged between the first input shaft 16 and casing 1 and second bearing 18, if
First input gear on the first input shaft 16 is put, one end of the first input shaft 16 being arranged on and be located on the outside of casing 1 first
Flywheel 19；First output shafting 4, including the first output shaft 24, the first output gear 23 being arranged on the first output shaft 24, if
Put the 3rd bearing 21 and fourth bearing 25, the first input gear and the first output gear between the first output shaft 24 and casing 1
23 engagements；Second input shafting 3, including the second input shaft 6, the second input gear being arranged on the second input shaft 6, are arranged on
5th bearing 7 and 6th bearing 8 between second input shaft 6 and casing 1, are arranged on the one end of the second input shaft 6 and outside casing 1
Second flywheel 9 of side；Second output shafting 5, including the second output shaft 14, the second output gear being arranged on the second output shaft 14
Wheel 13, is arranged on 7th bearing 11 between the second output shaft 14 and casing 1 and 8th bearing 15, the second input gear and second defeated
Go out gear 13 to engage.The first input shaft 16 and the second input shaft 6 are driven respectively by two motors in the present embodiment, pass through gear
Engagement transfers torque to two output shafts, and then the blade up and down for dragging output end carries out cutting steel plate.In order that whole fly
It is stable to cut cutting system, makes velocity perturbation change in the range of one allows, therefore in the first input shaft 16, the second input shaft
The flywheel of one big the moment of inertia is provided with 6.Flywheel is arranged on input shaft by the present embodiment, and input shaft is high speed shaft, root
According to law of conservation of energy, its rotary inertia is transformed on output shaft 14 and output shaft 24 with the quadratic relationship of fast ratio, that is, is being exported
When axle needs the rotary inertia of certain value, it is multiplied by output shaft for the rotary inertia of output shaft in the rotary inertia needed for input shaft and turns
Speed and square of the ratio of input speed, input shaft rotating speed be more than output rotating speed be rotary inertia needed for output shaft end more
Small, i.e. flywheel weight is mitigated, and be may be such that whole device lightweight, is reduced material cost.The present embodiment uses double
Input shaft and dual output shaft design, the output end positioned at the second output shaft of casing top 14 are connected with upper knife edge by crank,
The first output shaft 24 positioned at lower box is connected with lower blade by crank, makes blade cooperation up and down by motor driving
Steel plate is sheared.The design of dual input can utilize two power more small machines compared to the design of original single motor
Go to drive upper knife edge and lower blade respectively, reduce the demand to motor performance on the whole.
To obtain big speed reducing ratio, the number of teeth of the first input gear is less, and gear compound graduation circular diameter is smaller, partial installation,
Then axle can be thinner, and from the aspect of intensity, axle is just into the weak link of intensity.Therefore the first input gear and input shaft are closed
Into an entirety, i.e. the first input shaft 16 and the second input shaft 6 are gear shaft.First output gear 23 and first in the present embodiment
Output shaft 24, the second output gear 13 are connected with the second output shaft 14 using flat key, are that gear and axle are normal using flat key connection
Connected mode, it will be understood by those skilled in the art that gear is also connected with axle with other connected modes, such as spline,
This is not enumerated successively.
To ensure to be synchronized with the movement between blade up and down, ensure the upper knife edge and the first output shaft 24 of the second output shaft 14 connection
Coordinate between the lower blade of connection, the first output gear 23 engages with the second output gear 13.First output gear in the present embodiment
Wheel 23 is vertical with the axial connecting line of the second output gear 13, and the first output gear 23 is identical with 13 big I of the second output gear also may be used
It is different.Now two motor counter-rotatings simultaneously, sliding tooth roller box the first input shaft 16, the second input shaft 6, are engaged by gear
Two output shafts are transferred torque to, and then the blade up and down for dragging output end carries out steel plate cutting.
Further, the first input shaft 16 is provided with one end of the first flywheel 19 and is also associated with first clutch 20, user
Connection and disconnection that first clutch 20 realizes the first flywheel 19 and the first input shaft 16 can be operated according to operating mode.Similarly, second
One end that input shaft 6 is provided with the second flywheel 9 is also associated with second clutch 10.Specifically, when the speed for the middle embryo for needing to shear
Degree≤0.8m/s, the first flywheel 19 of connection and the first input shaft 16, the second flywheel 9 and the second input shaft 6, i.e. the first flywheel 19,
Second flywheel 9 is started working.First clutch 20, second clutch 10 are that multiple-piece pneumatically rubs clutch in the present embodiment
Device.
Each embodiment is described by the way of progressive in this this specification, what each embodiment stressed be and its
The difference of its embodiment, between each embodiment identical similar portion mutually referring to.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
