Abstract
The utility model discloses a flying shear transmission mechanism of a crank, which comprises an upper shearing gear, a lower shearing gear, a high-speed gear shaft A and a high-speed gear shaft B. The upper shearing gear meshes with the lower shearing gear, the high-speed gear shaft A and the high-speed gear shaft B are respectively arranged on the left side and the right side of the lower shearing gear symmetrically, and gears of the high-speed gear shaft A and the high-speed gear shaft B respectively mesh with the lower shearing gear. The flying wheel shear transmission mechanism of the crank reduces using power of a single motor, the diameter of the high-speed gear shafts and modules of the gears are decreased, rotational inertia is reduced simultaneously, and both starting time of the motor and time for reaching the required shearing speed are shortened.
Description
Technical field
The utility model relates to metallurgy, steel rolling field, especially relates to a kind of crank flying shear driving mechanism.
Background technique
Flying shear is rolled piece to be implemented to shear technology in metallurgical steel rolling industry, is one of key equipment indispensable on the continous way steel rolling production-line.The long-time effectively operation of flying shear can reduce the incidence rate of piling the steel accident in rolling process, reduces the processing time of heap steel accident, guarantees carrying out smoothly of steel rolling process.Flying shear be generally used for to rolled piece implement crop, back-end crop, to cut multiple length, segmentation and accident cataclasm, often is in " throat " position of technological process on steel rolling production-line.
As shown in Figure 1, traditional crank flying shear driving mechanism is single motor driving, it comprises: high speed gear shaft A 3, on shear gear 1 and down cut gear 2, high speed gear shaft A 3 drives down cut gear 2, down cut gear 2 drives to go up shears gear 1, down cut gear 2 and last shearing gear 1 are done the synchronous backward motion, and traditional crank flying shear driving mechanism is applicable to the flying shear mechanism that shears the light section stocking; But shearing for big section stocking, flying shear mechanism just needs very big shearing force, therefore, flying shear mechanism just needs very powerful motor driving, will require the modulus of the diameter of high speed gear shaft and gear parts all can be very big like this, bring no small difficulty for the design and the manufacturing of high speed gear shaft.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of crank flying shear driving mechanism, can reduce the rotary inertia of system effectively, shortens the system start-up time, boosts productivity.
In order to realize the foregoing invention purpose, the utility model adopts following technological scheme:
A kind of crank flying shear driving mechanism, it comprises shears gear, down cut gear, high speed gear shaft A and high speed gear shaft B, last shearing gear and down cut gear engagement, high speed gear shaft A and high speed gear shaft B are separately positioned on the bilateral symmetry both sides of down cut gear, the gear on high speed gear shaft A, the high speed gear shaft B respectively with the down cut gear engagement.
Described crank flying shear driving mechanism, its down cut gear, high speed gear shaft A and high speed gear shaft B are centered close on same the horizontal linear.
Described crank flying shear driving mechanism, its high speed gear shaft A and the centre distance that goes up between the shearing gear equal high speed gear shaft B and go up the centre distance of shearing between the gear.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
This crank flying shear driving mechanism, it adopts the dual-motor structure, drive the down cut gear simultaneously by two high speed gear shafts that are connected on two motors, reduced the use power of single motor, reduce the cog modulus of part of the diameter of high speed gear shaft and axle, simultaneously also reduced rotary inertia, shortened the time of electric motor starting, shorten the time that obtains shearing required speed, be well positioned to meet the needs of shearing process parameter.
Description of drawings
Fig. 1 is the structural representation of the traditional crank flying shear kind of drive;
Fig. 2 is a structural representation of the present utility model;
Among the figure: the last shearing of 1-gear; 2-down cut gear; 3-high speed gear shaft A; 4-high speed gear shaft B.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 2, this crank flying shear driving mechanism, comprise and shear gear 1, down cut gear 2, high speed gear shaft A 3, high speed gear shaft B 4, last shearing gear 1 and 2 engagements of down cut gear, high speed gear shaft A and high speed gear shaft B are separately positioned on the bilateral symmetry both sides of down cut gear, gear on high speed gear shaft A, the high speed gear shaft B respectively with the down cut gear engagement, described crank flying shear driving mechanism, its down cut gear, high speed gear shaft A and high speed gear shaft B are centered close on same the horizontal linear; Described crank flying shear driving mechanism, its high speed gear shaft A and the centre distance that goes up between the shearing gear 1 equal high speed gear shaft B and go up the centre distance of shearing between the gear 1.
During work, drive 2 rotations of down cut gear simultaneously by being connected two high speed gear shaft A 3, high speed gear shaft B 4 on the motor respectively, down cut gear 2 drives again shears gear 1, down cut gear 2 rotates with last shearing gear 1 synchronous backward, reduced the use power of single motor, reduced the cog modulus of part of the diameter of high speed gear shaft and axle, simultaneously also reduced rotary inertia, shortened the time of electric motor starting and obtained time of required shearing speed.
