Be labeled as in figure:
1, platform deflector roll is with; 2, lining; 3, eccentric shaft; 4, the first angular contact ball bearing; 5, the second angular contact ball bearing; 6, triangle contact ball bearing; 7, locking back of the body cap; 8, labyrinth gland; 9, looping bed; 10, rolled piece; 11, oil inlet pipe; 12, oil-feed back of the body cap.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, be described in further detail the specific embodiment of the present invention, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contribute to its enforcement.
As shown in Figure 1, the present invention is specifically related to a kind of Horizontal loose sleeve roller (guide) apron, comprise looping bed 9, with platform deflector roll 1 and the lining 2 be located in band platform deflector roll 1, roller (guide) apron also comprises eccentric shaft 3, bearing group and the locking device for locking bearing group two ends, eccentric shaft 3 comprises the first axle part connecting setting successively, connecting portion and the second axle part be located in lining, band platform deflector roll 1 is connected with looping bed 9 by the first axle part, bearing group to be located between the second axle part and lining 2 and to be born respectively towards the axial load of bearing group two ends axial direction by the arranged in series between bearing and back-to-back configuration.This structure of bearings also has the effect connecting the second axle part and lining.
To be provided with away from one end of looping bed 9 with platform deflector roll 1 and spacing shoulder is carried out to bandaging piece 10.The contact jaw of shoulder and bandaging piece 10 is provided with rounding, to prevent wedge angle to the scuffing of rolled piece.After kink plays cover, rolled piece 10 is close to the band platform deflector roll sidewall motion of rotation, and shoulder can limit the height that rolled piece moves upward, and makes rolled piece operate in the centre position of roll path all the time, no longer contacts with guide and guard to produce with guide groove to scratch.Be positioned at the side of shoulder with platform deflector roll and lining is fastenedly connected by securing member, securing member can be bolt, and lining is fastened in band platform deflector roll preferably.
Consider actual needs and raw materials for production and cost, even more preferably, bearing group to comprise from the second axle part away from one end of looping bed 9 to the first angular contact ball bearing 4, second angular contact ball bearing 5 and the triangle contact ball bearing 6 set gradually near the direction of looping bed 9 one end, second angular contact ball bearing and the first angular contact ball bearing 4 are arranged in series, the axial force away from looping bed direction that rolled piece 10 produces after touching shoulder is on average born by the bearing of two arranged in series, and bearing capacity is the twice of traditional single-row bearing; Second angular contact ball bearing 5 and triangle contact ball bearing 6 are back-to-back configuration, and rigidity is high, can bear tilting moment.Each bearing of bearing group all adopts window punching press brass retainer, can run at up to the temperature of 150 DEG C.This bearing arrangement achieves radial direction to deflector roll and axial effective location, can bear the upwards huge axial forces produced after rolled piece plays cover, prevent the damage of bearing and axial workpiece.
Above-mentioned locking device comprises is located at the second axle part away from one end of looping bed 9 and for the first locking positioning device bearing of bearing group being carried out to axial location and lock bearing inner race.Be preferably, the first locking positioning device is locking back of the body cap 7, effectively can ensure the locking to all bearing inner races and axial location.
Locking device also comprises is located at the second locking positioning device of lining 2 near one end of looping bed 9 and for locating band platform deflector roll 1 and for locking the bearing outer ring of bearing group.Be preferably, the second locking positioning device is labyrinth gland 8, and as shown in Figure 1, the connecting portion of eccentric shaft 3 is provided with the structure that the tightening cover that to match with labyrinth gland 8 is combined, and constitutes a set of closed bearing block; In order to ensure the stability connected between lining and eccentric shaft further, be fastenedly connected by securing member between lining and labyrinth gland.The layout of this structure can ensure the locking of all bearing outer rings and the location of band platform deflector roll 1.
The lubricating system of bearing group is for adopting oil-air lubrication.Specifically, the first axle part below eccentric shaft 3 is provided with fuel feed hole, oil inlet pipe 11 relies on oil-feed back of the body cap 12 with holes to be arranged on the first axle part of eccentric shaft, oil inlet pipe 11 connects Oil/Gas Pipe, oil gas arrives the top the second axle part of eccentric shaft by oil inlet pipe 11, for the first angular contact ball bearing 4, second angular contact ball bearing 5, triangle contact ball bearing 6 provide oil-air lubrication, ensure that the cooling of bearing.
After adopting Horizontal loose sleeve roller (guide) apron of the present invention, each bearing stressed more reasonable, kink and the connecting mode between eccentric shaft and lining more reliable, do not occur because of bearing damage, deflector roll play and the accident caused again, equipment operates steadily, fault time and spare part expense significantly reduce, and operating rate of rolling mill and product quality significantly improve.
Below by reference to the accompanying drawings to invention has been exemplary description.Obviously, specific implementation of the present invention is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; Or without improvement, above-mentioned design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention.
