Abstract
The invention relates to a transmission device capable of sharing overload. The device is composed of multiple sets of main transmissions, each rack is provided with one set of the main transmission, and in each set of the main transmission, a main motor (6) drives the corresponding working rack (1) through a main deceleration system (2); each main deceleration system (2) is of a planet differential structure, a pair of bevel gears (4) and (5) are arranged between each set of the main deceleration system (2) and the main motor (6), and the bevel gears (5) are connected with the bevel gears of the adjacent racks through connecting shafts (7) and connected with a same overload motor (3); in each set of the main transmission, the main motor and the bevel gears connected with the overload motor simultaneously drives two input parts in the main deceleration system, and another part in the main deceleration system outputs the rotation speed and torque; the main motor and the overload motor jointly form the output rotation speed. According to the transmission device, each rack is still driven by the main motor separately, and flexible speed regulation can be achieved; meanwhile, the total installed capacity is greatly reduced, and energy sources are saved.
Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of transmission device of shared overload.
Background technology
In metallurgical steel rolling field, continuous rolling technology is current state-of-the-art technology, is widely used, and it can improve unit production capacity greatly, and the product quality of stocking and mechanical property good.Tandem rolling is the continuous rolling of by multiple frame, stocking being carried out to multi-pass, and every a time generally has one group of main transmission to drive.The operation of rolling of each passage has stable rolling and impact process of nipping, nip the attack time short (generally only having 1s), but shock loading is comparatively large, so often organize main transmission all require larger overload capacity, 1.5 ~ 2 times normally during stable rolling.Often organize transmission all to transship, great waste is created to general power.
Open the concentrated differential kind of drive subtracted in machine, mair motor only has mair motor and superimposed motor, each group frame is driven by a poor concentration speed reducer, overload can be shared when each frame is impacted, therefore, the general power of opening this concentrated differential kind of drive subtracting machine is lower 2-3 times than the general general power often organizing the independent a set of transmission of frame.But, concentrate the speed governing of the differential kind of drive often can not organize the independent speed governing of frame, there is the inflexible problem of speeds control.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of transmission device of shared overload, this device can speed governing flexibly, and can greatly reduce total installation of generating capacity, economize energy.
For achieving the above object, the invention provides following technical scheme:
A transmission device for shared overload, this device is made up of some groups of main transmissions, and each frame arranges one group of main transmission, often organizes main transmission and drives work housing 1 by a mair motor 6 by a main reduction train 2;
Described main reduction train 2 is planet differential structure, bevel-gear sett 4 and 5 is set often organizing between main reduction train 2 and mair motor 6, the bevel gear 5 being parallel to main transmission setting is connected with the bevel gear of adjacent rack by coupling spindle 7, and described bevel gear 4 is connected with same overload motor 3 with 5; The mair motor often organizing main transmission drives two input blocks in described main reduction train simultaneously with the described bevel gear be connected with overload motor, another parts output speed and moment of torsion in main reduction train; Output speed is made up of jointly mair motor and overload motor.
Further, described main reduction train 2 is planet differential structure, two input blocks in main reduction train are sun gear 10 and ring gear 9, the mair motor 6 often organizing main transmission drives the sun gear 10 in main reduction train 2, and the ring gear 9 in the main reduction train 2 of bevel gear driving be connected with overload motor 3, planet carrier 8 output speed in main reduction train 2 and moment of torsion; Output speed is made up of jointly mair motor 6 and overload motor 3, N

Beneficial effect of the present invention is: the transmission device of a kind of shared overload that the present invention proposes, each frame is still driven by independent mair motor, can speed governing flexibly.Often organize main transmission bear sting steel drift hit time, transship and to be realized by a shared overload motor, greatly reduce total installation of generating capacity, economize energy.
Accompanying drawing explanation
In order to make object of the present invention, technical scheme and beneficial effect clearly, the invention provides following accompanying drawing and being described:
Fig. 1 is the schematic diagram of device of the present invention;
Fig. 2 is main reduction train schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
Fig. 1 is the schematic diagram of device of the present invention, and as shown in the figure, this device is made up of some groups of main transmissions, and each frame arranges one group of main transmission, often organizes main transmission and drives work housing 1 by a mair motor 6 by a main reduction train 2;
Described main reduction train 2 is planet differential structure, and arrange bevel-gear sett 4 and 5 often organizing between main reduction train 2 and mair motor 6, speed ratio is 1, also can be other value; The bevel gear 5 being parallel to main transmission setting is connected with the bevel gear of adjacent rack by coupling spindle 7, and described bevel gear 5 is connected with same overload motor 3; The mair motor often organizing main transmission drives two input blocks in described main reduction train simultaneously with the described bevel gear be connected with overload motor, another parts output speed and moment of torsion in main reduction train; Output speed is made up of jointly mair motor and overload motor.
Fig. 2 is main reduction train schematic diagram, as shown in the figure, described main reduction train 2 is planet differential structure, two input blocks in main reduction train are sun gear 10 and ring gear 9, the mair motor 6 often organizing main transmission drives the sun gear 10 in main reduction train 2, and the ring gear 9 in the main reduction train 2 of bevel gear driving be connected with overload motor 3, planet carrier 8 output speed in main reduction train 2 and moment of torsion; Output speed is made up of jointly mair motor 6 and overload motor 3, N
nout=N
nmotor× i
n1+ N
n transships motor× i
n2, wherein overload motor speed N
