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, is related 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 greatly improve unit
Production capacity, and the product quality and mechanical property of stocking are good.Tandem rolling is to carry out continuously rolling for multi-pass to stocking by multiple frames
System, typically has one group of main transmission to be driven per a time.The operation of rolling of each passage has stable rolling and nips punching
Hit process, nip the attack time short (typically only have 1s), but shock loading is larger, so every group of main transmission required it is larger
Overload capacity, typically stable rolling when 1.5～2 times.Per group of transmission is all transshipped, and great wave is generated to general power
Take.
The concentration differential kind of drive in stretch reducing machine, mair motor only has mair motor and superimposed motor, by a poor concentration
Speed reducer drives each group of frame, and each frame can share overload when impacting, therefore, this concentration differential gearing of stretch reducing machine
The general power of mode is lower 2-3 times than the general power that every group of general frame single set is driven.But, concentrate the differential kind of drive
Speed governing can not the independent speed governing of every group of frame, there are problems that speeds control is inflexible.
The content of the invention
In view of this, it is an object of the invention to provide a kind of transmission device of shared overload, the device can flexibly speed governing,
And can greatly reduce total installation of generating capacity, energy saving.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of transmission device of shared overload, the device is made up of some groups of main transmissions, and each frame arranges one group of main biography
Dynamic, every group of main transmission drives work housing 1 by a mair motor 6 by a main reduction train 2；
The main reduction train 2 is planet differential structure, and a pair of cone teeth are arranged between per group of main reduction train 2 and mair motor 6
Wheel 4 and 5, the bevel gear 5 arranged parallel to main transmission is coupled by coupling spindle 7 with the bevel gear of adjacent rack, the bevel gear 4
It is connected with same overload motor 3 with 5；The mair motor of every group of main transmission and it is described with overload motor connection bevel gear simultaneously
Two input blocks in the main reduction train are driven, another part output speed and moment of torsion in main reduction train；Output turns
Speed is collectively formed by mair motor and overload motor.
Further, the main reduction train 2 is planet differential structure, and two in main reduction train input block is sun gear 10
With ring gear 9, the mair motor 6 of every group of main transmission drives the sun gear 10 in main reduction train 2, and the cone being connected with overload motor 3
Gear drives the ring gear 9 in main reduction train 2, the output speed of planet carrier 8 and moment of torsion in main reduction train 2；Output speed is by leading
Motor 6 and overload motor 3 are collectively formed, Nnout=Nnmotor×in1+NN transships motor×in2, wherein overload motor speed NN transships motorIt is permanent
It is fixed, NnoutSpeed governing by mair motor NnmotorRealize.
The beneficial effects of the present invention is：A kind of transmission device of shared overload proposed by the present invention, each frame still by
Individually mair motor drives, can flexibly speed governing.Every group of main transmission bear sting steel and impact when, transship by a shared overload electricity
Machine realization, greatly reduces total installation of generating capacity, energy saving.
Description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carries out
Explanation：
Fig. 1 is the schematic diagram of device of the present invention；
Reduction train schematic diagram based on Fig. 2.
Specific embodiment
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, as illustrated, the device is made up of some groups of main transmissions, each machine
Frame arranges one group of main transmission, and every group of main transmission drives work housing 1 by a mair motor 6 by a main reduction train 2；
The main reduction train 2 is planet differential structure, and a pair of cone teeth are arranged between per group of main reduction train 2 and mair motor 6
Wheel 4 and 5, speed is than being 1, or other values；Pass through coupling spindle 7 and adjacent rack parallel to the bevel gear 5 that main transmission is arranged
Bevel gear connection, the bevel gear 5 is connected with same overload motor 3；The mair motor of every group of main transmission and described with mistake
The bevel gear of motor connection is carried while driving two input blocks in the main reduction train, another part in main reduction train
Output speed and moment of torsion；Output speed is collectively formed by mair motor and overload motor.
Reduction train schematic diagram based on Fig. 2, as illustrated, the main reduction train 2 is planet differential structure, in main reduction train
Two input blocks are sun gear 10 and ring gear 9, and the mair motor 6 of every group of 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 being connected with overload motor 3, the output turn of planet carrier 8 in main reduction train 2
