Model utility content
The purpose of this utility model be to provide a kind of for roller hearth heat-treated furnace can bidirectional movement chain transmission drive system, when roller hearth heat-treated furnace stops discharging because of fault, can bidirectional movement chain transmission drive system can also realize continuous reciprocally swinging operation.
The utility model content is:
A kind of can bidirectional movement chain transmission drive system, it is characterized in that: two sprocket wheel tensioning conversion equipments divide and are located at propelling chain transmission drive system two ends, a closed chain is contained on two sprocket wheel tensioning conversion equipments, on one side chain of the closed chain between two sprocket wheel tensioning conversion equipments, be provided with the main changing device that turns, chain and the main output sprocket engagement that turns the speed reducer on changing device, in speed reducer, there is discharging chain wheel shaft and drive input shaft, between discharging chain wheel shaft and driving input shaft, there is variable-speed shaft, a gear engagement on gear on driving input shaft and variable-speed shaft, another gear on variable-speed shaft and the gear engagement driving on input shaft, drive the sprocket wheel of the outer side of input shaft to connect the sprocket wheel on reducing motor by chain, drive the opposite side axle head outside input shaft to be processed into square toes, and be furnished with hand crank.
Described tensioning conversion equipment respectively have up and down one to turn to sprocket wheel, turn to up and down the inner side between sprocket wheel to have a tension sprocket, tension sprocket is contained on a leading screw level adjuster.
Described master turns on changing device has two to turn to sprocket wheel, the chain coming from a direction by with one turn to sprocket engagement to turn to again with the output sprocket of speed reducer to mesh, from the output sprocket of speed reducer chain out, by turning to sprocket engagement with another, be transmitted to another direction again.
The utility model beneficial effect:
The roller-way being comprised of many furnace rollers in roller hearth heat-treated furnace, material with process speed operation, can bidirectional movement chain transmission drive system can be realized continuous reciprocally swinging operation on roller-way.When heat treatment furnace stops discharging because of fault, automatically switch and carry out reciprocally swinging, prevent that furnace roller and material from deforming under hot environment.
Can bidirectional movement chain drive technology can realize the automatic switchover of reciprocally swinging.When heat treatment furnace stops discharging because of fault, automatically switch and carry out reciprocally swinging operation, prevent that furnace roller and material from deforming under hot environment.
This drive system is by reducing motor, the compositions such as speed reducer, chain sprocket and conversion tension device.And be furnished with man-operated mechanism, when there is unexpected power-off or there was a mechanical failure, by man-operated mechanism operation speed reducer, rotate furnace roller or material is manually come out of the stove.

Accompanying drawing explanation
Fig. 1 is can bidirectional movement chain transmission drive system structural front view
Fig. 2 is can bidirectional movement chain transmission drive system structure plan view
In figure: 1 reducing motor, 2 speed reducers, 3 main changing device, 4 tensioning conversion equipments, 5 chains, 6 sprocket wheels, 7 hand cranks of turning.
Embodiment
As shown in the figure a kind of can bidirectional movement chain transmission drive system, two sprocket wheel tensioning conversion equipments divide and are located at propelling chain transmission drive system two ends, a closed chain is contained on two sprocket wheel tensioning conversion equipments, on one side chain of the closed chain between two sprocket wheel tensioning conversion equipments, be provided with the main changing device that turns, chain and the main output sprocket engagement that turns the speed reducer on changing device, in speed reducer, there is discharging chain wheel shaft and drive input shaft, between discharging chain wheel shaft and driving input shaft, there is variable-speed shaft, a gear engagement on gear on driving input shaft and variable-speed shaft, another gear on variable-speed shaft and the gear engagement driving on input shaft, drive the sprocket wheel of the outer side of input shaft to connect the sprocket wheel on reducing motor by chain, drive the opposite side axle head outside input shaft to be processed into square toes, and be furnished with hand crank.
Described tensioning conversion equipment respectively have up and down one to turn to sprocket wheel, turn to up and down the inner side between sprocket wheel to have a tension sprocket, tension sprocket is contained on a leading screw level adjuster.
Described master turns on changing device has two to turn to sprocket wheel, the chain coming from a direction by with one turn to sprocket engagement to turn to again with the output sprocket of speed reducer to mesh, from the output sprocket of speed reducer chain out, by turning to sprocket engagement with another, be transmitted to another direction again.
The roller-way being formed by many furnace rollers in roller hearth heat-treated furnace, material is with process speed operation on roller-way, and material is transported to lower operation automatically after coming out of the stove.
Can bidirectional movement chain transmission drive system drive speed reducer 2 runnings by variable frequency reducer motor 1, according to any adjust operation speed of the different technological requirement of each product.Speed reducer output sprocket becomes chain link with furnace roller chain wheel set.For adjusting chain elasticity, in driving chain link both sides, tension device 4 is housed, when upper and lower processing apparatus goes wrong or when other reason causes heat treatment furnace to stop discharging, reducing motor clockwise and anticlockwise switchover operation, furnace rolls road carries out continuous reciprocally swinging, prevents under hot environment furnace roller and material deform (the highest furnace temperature can reach 1000 ℃ of left and right).
When there is unexpected power-off or there was a mechanical failure, operator shake speed reducer 2 with hand crank mechanism 7, and to rotate furnace roller (be furnace roller to direction rotation 180 degree, anti-turnback again, perseveration) or material is slowly come out of the stove, avoid having an accident blowing out or produce waste product.
