Description
Technical field
The present invention relates to the transmissions of slab conveying roller on roll mill, more specifically to a kind of rolling-mill housing
Roller drive arrangement.
Background technique
Vertical miller and roughing mill can be installed together in general Thick Plate Plant rolling line region, vertical miller is close to roughing mill
It is arranged before machine.As shown in Figure 1, it is respectively disposed with the standing roller frame roller 2 of a set of two roller-ways composition in 1 front and back of vertical miller rack,
Play the role of conveying slab disengaging milling train.Just because of standing roller frame roller 2 is close to vertical miller rack 1 and roughing mill 3 is arranged, lead
In the upper standing roller frame roller 2 of spatial position layout, there are very big inconsistent phenomenons with driving motor 4 for cause.And at home and abroad milling train is arranged
In, transmission agency is realized under this spatial position constrained environment, generally universal shaft 5 is selected to be driven in design, borrowed
Help universal shaft 5 that can connect out of line two components, to realize the effect of transmitting torque.
But the transmission of universal shaft 5 haves the defects that its is intrinsic, and the service life depends primarily on cross shaft bearing service life.Due to
Standing roller frame roller 2 is arranged in vertical miller rack 1, in process of production impact vibration of the rolled plate to standing roller frame roller 2
Especially acutely, while heavy plate mill is reversable mill, and steel plate passes through milling train frequently forward and reverse rolling final molding, therefore universal
Axis 5 is subjected to frequent alternating load, and the rolled slab substance of heavy plate mill is big, causes driving torque also bigger, thus phase
Also need to increase corresponding size when 5 crosshead of the universal shaft design answered, once but crosshead it is excessive, will affect universal shaft 5 can be with inclining
Angular region.The standing roller frame roller 2 and 4 largest axis angle theta of driving motor of slab have reached 17.2 °, when universal shaft 5 designs thus
Its size is also restricted, and 5 cross axle portion structure of universal shaft is more weak.Since high inclination-angle is driven, lead to the flower of universal shaft 5
Key is paid effective contact area when rotary drive and is reduced, and unilateral stress is concentrated, and concentrated wear is caused to aggravate, and spline pair gap is larger,
Aggravation is vibrated when transmission.Often occur machine on universal shaft 5 in actual use at the scene and just occurs the change of cross jaw bearing clearance soon
Greatly, gap, which increases, causes vibration to aggravate, and dynamic balance is poor in high-speed rotation.In addition the frequent forward and backward of standing roller frame roller 2,
In the case where steel plate kowtows shock and alternating load, universal axis connection bolt frequent failure loosens, driving key abrasion.And ten thousand newly replaced
Just start transmission accuracy reduction occur within machine general 1~2 month on axis 5, cross head bearing disabling damage causes Frequent Troubles.
Once universal shaft 5 on standing roller frame roller 2 damages failure, will lead to slab in the operation of rolling be stuck on standing roller frame roller 2 and
It normally can not complete to roll into and out of milling train, or steel plate occur, blank deflection occurs when entering milling train, so that it is existing to form angular rolling
As influencing steel plate final molding size, the normal Rolling Production of strong influence.
Summary of the invention

Assembling.The center line of the input shaft 13 is overlapped with the center line of driving motor 10, universal shaft 11, the output shaft 14
Center line is overlapped with the center line of breast roll roller-way 12.Due to driving motor 10 and the cloth substantially on same center line of input shaft 13
Postpone 11 swing angle of universal shaft do not need it is excessive, thus realize by 11 overall structural strength of universal shaft increase, to improve maximum
Determine torque, steel plate single weight is big, impact vibration is big and the operating condition of frequent forward and backward to meet when slab rolling line produces.Output
The drum-shaped tooth type shaft coupling 141 installed on 14 spindle nose of axis by interference fit and the other half installed on 12 spindle nose of breast roll roller-way
121 tooth form of drum-shaped tooth type shaft coupling, size are identical, and two shaft couplings 141,121 are linked together by external tooth cover 23, are passed through
Gear engages to transmit torque.Due to selecting cydariform toothing, allow to install, there are two a small amount of axis are not right in use process
Middle phenomenon, consequently facilitating install, safeguard in the future.The end-tooth of 13 spindle nose position of input shaft installation takes over 131 firmly, passes through universal shaft
11 take over 131 with the end-tooth on driving motor 10 firmly is connected.Due to using end-tooth form, when than original " one " keyboard transmission
The field of conjugate action is higher, and bolt is not easy stress elongation, and more secure and reliable is used under large torque, HI high impact environment.
Heavy plate mill stings steel when rolling and throwing steel speed is not high, therefore bath lubrication side can be used in this gear reduction box
Formula is equipped with pouring orifice and exhaust valve 162 in top of the box, and the bottom of box is equipped with sewage draining exit and oil scale 172, periodically opens oiling
Mouth can carry out checking to box house gear lubrication situation and oil liquid updates.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
