Abstract
The utility model discloses a front driving roller for a continuous casting shear. The utility model is composed of a chain wheel, a shaft, a roller and an overrunning clutch in the chain wheel. An electric motor and the chain wheel are rotated only when the tail blank is conveyed, the roller is disconnected with the power section when the casting blank is not positioned in state of the tail blank, and thereby, the resistance force of blank drawing is reduced, the operating rate of the casting machine is improved, and the service life of the driving roller is extended. Construction investment does not need to be increased because the utility model has the advantage of compact structure. The utility model is favorable for the integral arrangement of workshops.
Description
The utility model relates to a kind of continuous casting and cuts preceding live-roller.
The conticaster that each big steel mill of present China uses, live-roller was formed by sprocket wheel, axle, roller before it was cut, and sprocket wheel and roller all are directly installed on the axle, and when transmitting the tail base, the motor drives sprocket wheel passes through axle by sprocket wheel again and drives a roller.The weak point of this live-roller is that when strand was in non-tail blank state, roller did not need to transmit power, and this moment roller and power section broken not open, and motor and sprocket wheel will become the transmission of load obstruction strand on roller of live-roller.Because caster work rate and strand transfer rate are proportional, the transmission speed of strand reduces, and operating rate is reduced.When roller did not need to transmit power, motor and sprocket wheel also always were in rotary state for a long time, not only increase the wearing and tearing that resistance has quickened roller simultaneously, and the life-span of motor and sprocket wheel also can reduce greatly.
The purpose of this utility model is to provide a kind of transmission resistance little, transmission system life-span height, and the continuous casting of compact conformation is cut preceding live-roller.
In order to achieve the above object, the utility model has been done further improvement on the basis of the live-roller of being made up of sprocket wheel, axle, roller at present, between sprocket wheel and axle a freewheel clutch is installed.The core wheel of freewheel clutch is installed in the end of axle, the roller of freewheel clutch is worked in the wedge shape cavity of core wheel and the formation of sprocket wheel inwall, the sleeve that is freewheel clutch is directly substituted by sprocket wheel, a bearing has been installed on the end of the core wheel of freewheel clutch, in order to support the sprocket wheel of its outside, the sprocket wheel other end is by being installed in another bearing supporting on the axle.
Because the utility model has adopted freewheel clutch, make live-roller only when transmitting the tail base, motor and sprocket wheel just rotate, and when strand is in non-tail blank state, roller and power section disconnect, and sprocket wheel and motor no longer are being with along with the rotation of roller and are being rotated, and have reduced resistance of billet withdrawal thus, improve the operating rate of casting machine, prolonged the life-span of whole live-roller.It is compact conformation that the utility model also has an advantage, because freewheel clutch is installed in sprocket wheel inside, to how much changing hardly that the locus occupies, need not to increase capital expenditure, helps the entire arrangement of production site.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 cuts the main cutaway view of preceding live-roller for the utility model continuous casting.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Fig. 1 shows whole structure of the present utility model substantially, the core wheel 4 of freewheel clutch is connected by the end of key with axle 2, the roller 5 of freewheel clutch is installed in the formed wedge shape cavity of inwall of described core wheel 4 and sprocket wheel 1, and by cover plate 8 roller 5 is covered, with the movement locus of restriction roller.The another side of being close to cover plate 8 is mounted in the bearing 6 on the core wheel 4, in order to supporting wheel 1, the other end of sprocket wheel 1, by being installed in bearing 7 supportings on the axle 2, one pad 9 is housed between bearing 7 and the core wheel 4, same end face at axle 2 and core wheel 4 also is equipped with locked spacer 10 and back-up ring 11, and the two ends of sprocket wheel 1 are equipped with a stifle 12 and saturating lid 13 respectively.Roller 3 is welded on the axle 2.
Live-roller is when transmitting the tail base, roller 3 needs motor to pass through transmission system drives such as sprocket wheel 1, in conjunction with Fig. 2 as can be seen, when motor drives sprocket wheel 1 rotates counterclockwise, the roller 5 of freewheel clutch, be subjected to the tangential frictional force of the counterclockwise circumference of sprocket wheel 1 inwall and by wedging at wedge shape cavity, the core wheel 4 that described thus roller 5 drives freewheel clutches also counterclockwise rotates, then by axle 2 roller 3 is rotated, this moment, the tail base obtained transmitting.When strand is in non-tail blank state, do not need roller 3 that transmission power is provided, this moment, strand forwarded voluntarily, roller 3 was subjected to forward, promptly anticlockwise circumference tangent direction friction power, roller 3 is rotated counterclockwise by this frictional force effect, at this moment also along with rotating counterclockwise, roller 5 then is in the width position of wedge shape cavity to the core wheel 4 of freewheel clutch, so sprocket wheel 1 can not rotate, thereby disconnected being connected of roller 3 and power section, resistance reduced greatly when strand was transmitted.
The utility model can improve the conticaster operating rate, prolong cut before live-roller service life, and compact conformation, reliable operation, install and use at the scene of being convenient to, and does not increase capital expenditure again.
Claims (2)
1, a kind of continuous casting is cut preceding live-roller, it is by sprocket wheel, axle, roller is formed, when transmitting the tail base, the motor drives sprocket wheel, drive roller again by axle, make the tail base be transmitted shearing, it is characterized in that having installed one between described sprocket wheel [1] and the axle [2] can make roller [3] when not needing to transmit power, the freewheel clutch that can disconnect with power section, the core wheel of described freewheel clutch [4] is installed in the end of axle [2], the roller of freewheel clutch [5] is positioned at the wedge shape cavity of the inwall formation of core wheel [4] and sprocket wheel [1], a bearing [6] has been installed on the core wheel end of freewheel clutch, in order to support the sprocket wheel [1] of its outside, the other end of sprocket wheel [1] is by being installed in another bearing [7] supporting on the axle [2].
