Abstract
The utility model provides a rolling mill with shift reducing gear box which characterized in that: the driving oil cylinder of rolling mill drives shift fork drive shaft rotating, the shift fork transmission shaft drives to pull out plugs in a shift fork external tooth cover, the internal tooth cover sliding connection sheathe in at the external tooth, the external tooth cover is fixed on the transmission shaft, gear an and gear b set up in external tooth cover both sides respectively and rotate and connect on the transmission shaft, the one end number of teeth and modulus that gear an and gear b are close to the external tooth cover are the same with the internal tooth cover, power input shaft connects through assembly gear c and the epaxial gear d transmission of transmission above that, last gear e and the gear f of power output shaft meshes with epaxial gear b of transmission and gear a respectively mutually, the utility model has the advantages of the rolling mill did not need to be changed different power when the adjustment is used according to different technologies motor carries out work, and this novel adoption rolling mill oil cylinder drive shift fork system carries out the shift speed governing for equipment cost greatly reduced.
Description
Technical field
The utility model relates to a kind of milling train, particularly a kind of milling train with shift speed reducer.
Background technique
Traditional milling train speed reducer does not possess the regulatory function that shift slows down, when meeting different process requirement, the power of motor can only be changed, supporting corresponding high-low-voltage electrical equipment simultaneously, cause the waste of input, it is very inconvenient to use, and it is expensive to be equipped with independent gearbox, and equipment cost is increased greatly.
Model utility content
For the deficiencies in the prior art, the utility model aims to provide a kind of milling train with shift speed reducer, has automatic regulation function, greatly saves cost of production.
To achieve these goals, the utility model adopts following technological scheme:
A kind of milling train with shift speed reducer, it is characterized in that: the driving oil cylinder of milling train drives shift fork transmission shaft to rotate, shift fork transmission shaft drives plug axle shift fork external tooth cover, internal tooth casing is slidably connected on external tooth cover, external tooth cover is fixed on transmission shaft, gear a and gear b is separately positioned on external tooth cover both sides and is rotatably connected on transmission shaft, gear a is identical with internal tooth casing with modulus near one end number of teeth of external tooth cover with gear b, power input shaft is in transmission connection by the gear d on assembling gear c thereon and transmission shaft, gear e on pto＝power take-off and gear f is meshed with the gear b on transmission shaft and gear a respectively.
Shift fork propeller shaft slip is nested on external tooth cover.
Drive oil cylinder to be connected with the gear transmission being assemblied in shift fork transmission shaft by tooth bar, shift fork transmission shaft rotarily drives plug axle disposed thereon and swings, and plug axle is slidably connected on the groove of external tooth cover.
The beneficial effects of the utility model are: milling train does not need the motor changing different capacity to carry out work when using according to different process adjustment, and this novel employing milling train hydraulic oil cylinder driving shift fork system carries out shift speed governing, and equipment cost is reduced greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is shifting fork mechanism schematic cross-section of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model will be further described, it should be noted that, the present embodiment, premised on the technical program, give detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to the present embodiment.
As Fig. 1, shown in 2, a kind of milling train with shift speed reducer, it is characterized in that: the driving oil cylinder 1 of milling train drives shift fork transmission shaft 2 to rotate, shift fork transmission shaft 2 drives plug axle 3 shift fork external tooth cover 4, internal tooth casing 4 is slidably connected on external tooth cover 11, external tooth cover 11 is fixed on transmission shaft 8, gear a9 and gear b10 is separately positioned on external tooth cover 11 both sides and is rotatably connected on transmission shaft 8, gear a9 is identical with internal tooth casing 4 with modulus near one end number of teeth of external tooth cover 11 with gear b10, power input shaft 5 is in transmission connection by the gear d7 on assembling gear c6 thereon and transmission shaft 8, gear e12 on pto＝power take-off 14 and gear f13 is meshed with the gear b10 on transmission shaft 8 and gear a9 respectively.
Shift fork transmission shaft 2 slides and is nested on external tooth cover 4.
Drive oil cylinder 1 to be connected with the gear transmission being assemblied in shift fork transmission shaft 2 by tooth bar, shift fork transmission shaft 2 rotarily drives plug axle 3 disposed thereon and swings, and plug axle 3 is slidably connected on the groove of external tooth cover 4.
Gear e12 and gear b10 and gear f13 and gear a9 form two groups of different gear ratio, speed change switching is carried out by driving oil cylinder 1 shift fork slip internal tooth casing 4, when driving oil cylinder 1 stroke to stretch out completely, external tooth cover 11 is connected as overall by internal tooth casing 4 with gear a9, realize the mating engagement of gear a9 and gear f13, now gear b10 freely rotates and does not participate in work; When driving oil cylinder 1 oil cylinder stroke to retract completely, external tooth cover 11 is connected with gear b10 as overall by internal tooth casing 4, and realize the mating engagement of gear b10 and gear e12, now gear a9 freely rotates and do not participate in work.
For a person skilled in the art, according to above technological scheme and design, various corresponding change and distortion can be provided, and all these change and distortion all should be included within the protection domain of the utility model claim.
