Abstract
The utility model relates to a flexible transmission device of a sintering machine, which comprises a transmission device. The transmission device is supported by a flexible supporting system. A large gear of a final-stage speed reducer in the transmission device is driven by two shunting speed reducers. The flexible transmission device is characterized in that the large gear in the final-stage speed reducer is driven by gears on output gear shafts of the two shunting speed reducers, and input shafts of the two shunting speed reducers are connected with an independent motor by a shaft joint. The flexible transmission device has the advantages that: as the traditional primary speed reducer and middle turbine speed reducer are replaced by a PR module type gear speed reducer, the flexible transmission device has compact structure and light weight; as the large gear of the final-stage speed reducer is driven by the gears of the output gear shafts of two PR module type gear speed reducers, the bearing capacity and total transmission efficiency are obviously improved.
Description
Technical field
The utility model relates to a kind of flexible transmission device of sintering machine, especially final stage is exported two improved flexible transmission device of sintering machine of shunting gear-box of gearwheel.
Background technique
Flexible transmission is all transmission system or part slow speed turbine stage transmission device (as the big pinion drive of final stage) are suspended on the carrying main shaft, and the flexible header system of being made up of elastic element (for example spring, elasticity torsion bar etc.) links to each other the gear housing that hangs with ground, make it to adapt, thereby can guarantee to keep between the big small gear of final stage good engagement with the deflection or the distortion of main shaft.This transmission is widely used in sintering machine.In order to reduce the overall sizes of flexible transmission system, generally adopted the method for power dividing, gearwheel at the final stage speed reducer is respectively equipped with elementary speed reducer, intermediate turbine speed reducer with both sides, speed reducer drives the intermediate reduction gear machine, passes through the gearwheel of the output worm drive final stage speed reducer of intermediate turbine speed reducer again.The BFT type flexible transmission device of sintering machine of the 4th edition (Chemical Industry Press publishes in January, 2002) the 15th piece of disclosed domestic use of the 3rd chapter of " mechanical design handbook " the 3rd volume all belongs to this class.
We find in the use, are respectively equipped with elementary speed reducer, intermediate turbine speed reducer at the gearwheel of final stage speed reducer with both sides, and volume is bigger, and structure is complicated, makes total transmission efficiency and bearing capacity all on the low side, and total transmission efficiency is generally 0.56～0.77.
Summary of the invention
The purpose of this utility model is, have elementary speed reducer, intermediate turbine speed reducer at the gearwheel that exists in the present flexible transmission device of sintering machine with both sides, volume is bigger, and structure is complicated, total lower problem of transmission efficiency provides a kind of new flexible transmission device of sintering machine.
The purpose of this utility model is achieved in that a kind of flexible transmission device of sintering machine, comprise the transmission device that flexible header system supports, the gearwheel of the final stage speed reducer in the transmission device drives by two shunting speed reducers, it is characterized in that: the gearwheel in the final stage speed reducer is by the gear drive on two shunting speed reducer output gear shafts, and the input shaft of two shunting speed reducers is connected with motor independently by shaft joint.
In the utility model: described two shunting speed reducers are PR modular type gear reduction unit.
In the utility model: the PR modular type gear reduction unit of selecting for use is the PMD4 type.
Advantage of the present utility model is: owing to adopt PR modular type gear reduction unit to substitute traditional elementary speed reducer, intermediate turbine speed reducer, compact structure, overall weight are lighter, because the gearwheel of final stage speed reducer is by the gear drive of the output gear shaft of two PR modular type gear reduction units, bearing capacity and total transmission efficiency all are significantly improved.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Among the figure: 1, shunting speed reducer, 2, the final stage speed reducer, 3, motor, 4, shaft joint, 5, gearwheel, 6, output gear shaft.
Embodiment
Accompanying drawing discloses the utility model embodiment's concrete structure without limitation, below in conjunction with accompanying drawing the utility model is further described.
Flexible transmission device of sintering machine is supported by flexible header system, as seen from Figure 1, the gearwheel 5 of final stage speed reducer 2 is by the gear drive on two shunting speed reducer 1 output gear shafts 6, and the input shaft of two shunting speed reducers 1 is connected with motor 3 independently by shaft joint 4.During concrete enforcement, two shunting speed reducers 1 can adopt PR modular type gear reduction unit.
The comparative trial of concrete effect of the present utility model:
Laiwu iron and steel group sintering plant has a BFT type sintering machine.The gentle elementary retarder weight that passes device of this sintering machine is 600kg, and reduction speed ratio is 16.75; The weight that contains the final stage retarder of planar quadratic and annular enveloping worm speed reducer is 1900kg, and reduction speed ratio is 18.67, and the gross weight of flexible gearing is 2500kg.Elementary speed reducer input torque is 176Nm, and it is 43.8KNm that worm decelerating machine goes out shaft torque, and total efficiency is 77%.
In July, 2008, this sintering machine to Laiwu iron and steel group sintering plant improved, the PR modular type gear reduction unit of selecting for use after the structure has adopted the PMD4 type, concrete type is the PMD409-315 of the hard flank of tooth, its specified output torque is 86KNm, total efficiency is 93%, and as seen its bearing capacity and efficient all greatly improve.The weight of flexible gearing is 1840kg, is lower than the gross weight of original elementary retarder and intermediate gearbox.
