Technical field
The utility model relates to a kind of step-up gear, especially a kind of cold rolling main transmission step-up gear.
Background technology
Because the special rolled technology of the high rotating speed of cold rolled sheet, high-power, high linear speed and high stability, requirement to main transmission gearbox is very high, main transmission gearbox on the present cold rolling line that uses all needs dependence on import or is designed the cooperation manufacture of domestic production by offshore company, not only price is high, volume is bigger, production cycle is also longer, the Installation and Debugging difficulty.
Summary of the invention
The purpose of this utility model is: at present cold rolling main transmission step-up gear dependence on import or by the modality for co-operation of offshore company design domestic production, the price of product is high, volume is bigger, production cycle is also long, a series of problems such as Installation and Debugging difficulty provide a kind of new cold rolled sheet main transmission step-up gear.
The purpose of this utility model is achieved in that a kind of cold rolled sheet main transmission step-up gear, comprises casing, input gear shaft and output gear shaft, it is characterized in that:
A) output gear shaft comprises upper and lower last output gear shaft that is arranged in parallel and following output gear shaft, and the output of upper and lower output gear shaft stretches out casing, and it is 1: 1 that former and later two travelling gears, the speed ratio between them are all arranged on the upper and lower output gear shaft; Upper and lower output gear shaft is positioned in the casing by the bearings of front and back;
B) be arranged in parallel about input gear shaft and following output gear shaft, the input gear shaft is provided with former and later two and drives gear wheel, and the input gear shaft is positioned in the casing by the bearings of front and back, and the input of input gear shaft stretches out casing;
C) two travelling gears engagements on two driving gear wheels on the input gear shaft and the following output gear shaft, two travelling gears on the upper and lower output gear shaft are meshing with each other.
In the utility model: two driving gear wheels on the input gear shaft and former and later two travelling gears on the upper and lower output gear shaft are helical teeth, and preceding back-geared helical teeth prolongs crossing " people " font that is along teeth directional.
In the utility model: support on the spring bearing of importing gear shaft and last output gear shaft and all be furnished with the bearing eccentric bushing.
In the utility model: described casing is made up of upper box, middle casing and lower box, be provided with the supporting bearing base of input gear shaft and following output gear shaft between middle casing and the lower box, be provided with the supporting bearing base of output gear shaft between upper box and the middle casing.
Advantage of the present utility model is: because step-up gear adopts a parallel input gear shaft and dual output gear shaft, one of them output gear shaft (following output gear shaft) is taken into account the speed increasing gear axle, provide power, compact conformation for another output gear shaft (going up output gear shaft) simultaneously; Because two driving gear wheels on the input gear shaft and former and later two travelling gears on the upper and lower output gear shaft are helical teeth, front and back gear helical teeth intersects along the teeth directional prolongation and is " people " shape, and can guarantee to import in gear shaft and the output gear shaft work does not have axial displacement; Because the casing of step-up gear is made up of upper box, middle casing and lower box, installation and maintenance are all very convenient; Owing to support in the bearing of importing gear shaft and last output gear shaft and all be furnished with the bearing eccentric bushing, can regulate driving pinion on input gear shaft and the following output gear shaft and the running clearance between the driving gear wheel by the bearing eccentric bushing, and regulate the running clearance between two travelling gears on the upper and lower output gear shaft.
